Sridhar S , Worby CJ , Bronson RA , Turbett SE , Oliver EH , Shea T , Rao SR , Sanchez V , Becker MV , Kogut L , Slater D , Harris JB , Walters MS , Walker AT , Knouse MC , Leung DT , Kelly P , Ryan ET , LaRocque RC , Earl AM . bioRxiv 2025 ![]() ![]() Antimicrobial resistance (AMR) is an urgent threat to public health, but gaps in surveillance limit the detection of emergent novel threats and knowledge about the global distribution of AMR genes. International travelers frequently acquire AMR organisms, and thus may provide a window into AMR dynamics in otherwise poorly monitored regions and environments. To assess the utility of travelers as global AMR sentinels, we collected pre- and post-travel stool samples from 608 travelers, which were screened for the presence of extended-spectrum beta-lactamase producing Enterobacterales, carbapenem-resistant Enterobacterales, and mcr-mediated colistin-resistant Enterobacterales. A total of 307 distinct AMR organisms were sequenced in order to determine genotypic patterns and their association with travel region and behavior. Travel-associated AMR organisms were overwhelmingly E. coli, which exhibited considerable phylogenetic diversity regardless of travel region. However, the prevalence of resistance genes varied by region, with bla (CTX-M-55) and bla (CTX-M-27) significantly more common in travelers returning from South America and South-Eastern Asia, respectively. Hybrid assembly and plasmid reconstruction revealed the genomic neighborhood of bla (CTX-M-55) frequently matched a motif previously linked to animal populations. Contact with animals was also associated with virulence factors in acquired AMR organisms, including carriage of the ColV plasmid, a driver of avian pathogenic E. coli. We identified novel variants of the mcr-1 gene in strains acquired from Western Africa, highlighting the potential for traveler surveillance to detect emerging clinical threats. Ongoing efforts to track travel-acquired organisms could complement existing global AMR surveillance frameworks. |
Diabetes distress among US adults with diagnosed diabetes, 2021
Alexander DS , Saelee R , Rodriguez B , Koyama AK , Cheng YJ , Tang S , Rutkowski RE , Bullard KM . Prev Chronic Dis 2025 22 E07 ![]() National prevalence of diabetes distress is unknown among US adults. This cross-sectional study examined the prevalence among US adults with diabetes using 2021 National Health Interview Survey data. Multivariable multinomial logistic regressions were used to estimate adjusted prevalence and prevalence ratios for diabetes distress. Adjusted prevalence of moderate and severe diabetes distress was 24.3% (95% CI, 22.5%-26.1%) and 6.6% (95% CI, 5.6%-7.8%), respectively. Prevalence was higher among people aged 18 to 64 years, women, and those with lower incomes. Findings highlight the importance of examining economic and social factors and integrating diabetes distress screening into diabetes management and services. |
Educational attainment and employment status of adults living with congenital heart disease in the United States, CH STRONG 2016-2019
Downing KF , Goudie A , Nembhard WN , Andrews JG , Collins RT , Oster ME , Benavides A , Ali MM , Farr SL . Birth Defects Res 2025 117 (2) e2452 ![]() BACKGROUND: Our objective was to characterize the education and employment history of young adults with congenital heart defects (CHD) living in the United States. METHODS: The 2016-2019 Congenital Heart Survey To Recognize Outcomes, Needs, and well-beinG collected data from young adults (ages 19-38) with CHD identified from active birth defect in Arkansas, Arizona, and Atlanta, Georgia. Educational attainment, employment history, and special education between kindergarten and 12th grade were self-/proxy-reported. Respondent percentages were standardized to the eligible population by CHD severity, birth year, site, sex, and maternal race/ethnicity and compared by CHD severity using p values from Z-scores. Log-binomial prevalence ratios (aPRs) assessed associations between respondent characteristics and outcomes, adjusting for CHD severity, age group, sex, race/ethnicity, and site. Employment models also adjusted for education. Point estimates were compared to the 2018 American Community Survey (ACS) 5-year general population estimates. RESULTS: Among 1438 respondents, 28.3% attained ≥ bachelor's degree and 22.1% were unemployed for ≥ 12 months. Estimates were comparable by CHD severity (aPRs ~1.0) and similar to general population estimates (in ACS, 21% attained ≥ bachelor's degree and 26% were unemployed). About 25.3% of adults with CHD received special education, more commonly adults with severe (32.9%) than nonsevere CHD (23.5%, p = 0.01). CONCLUSIONS: Among young adults with CHD, educational attainment and employment did not substantially differ by CHD severity or from general population rates. One in four used special education between kindergarten and 12th grade. Clinical guidelines recommend ongoing educational and vocational support to individuals with CHD as needed so this population continues to thrive. |

Pollack LM , Chang A , Lee JS , Shaffer T , Wall HK , Brawner CA , Thompson MP , Keteyian SJ , Sukul D , Luo F , Jackson SL . J Am Heart Assoc 2025 e037811 ![]() BACKGROUND: Cardiac rehabilitation (CR) can improve cardiovascular health. We identified whether CR participation was associated with fewer subsequent inpatient hospitalizations and emergency department visits and less Medicare and out-of-pocket expenditures, and whether outcomes varied by amount of participation. METHODS: This retrospective study used Medicare fee-for-service claims data, including beneficiaries with a CR-qualifying event in 2016. Participants attended ≥2 sessions of CR within 365 days of the event. Propensity score matching was used to identify CR-eligible nonparticipants. Difference-in-differences analyses were used to compare differences in outcomes before (2014-2015) and after (2018-2019; 2-year CR period=2016-2017) the CR period between participants and nonparticipants. RESULTS: We identified 57 668 CR-eligible beneficiaries after matching, with equal numbers of participants and nonparticipants. Nearly 65% of beneficiaries had a percutaneous coronary intervention, 33.5% had an acute myocardial infarction, 17.5% had a coronary artery bypass graft, and 16.8% had a heart valve repair/replacement. Compared with nonparticipants, participants had 47.6 fewer subsequent annual inpatient hospitalizations per 1000 beneficiaries (95% CI, -58.8 to -36.3) and $1005 lower subsequent annual Medicare expenditures per beneficiary (95% CI, -$1352 to -$659). Compared with no participation, medium participation (12-23 sessions), high participation (24-35 sessions), and CR completion (≥36 sessions) were associated with fewer inpatient hospitalizations and lower Medicare expenditures per year. CONCLUSIONS: CR was associated with fewer subsequent annual inpatient hospitalizations and lower subsequent annual Medicare expenditures. A higher amount of participation was associated with a further reduction in hospitalizations and expenditures. These findings can inform programs and policies that encourage CR participation. |

Tenforde MW , Noah KP , O'Halloran AC , Kirley PD , Hoover C , Alden NB , Armistead I , Meek J , Yousey-Hindes K , Openo KP , Witt LS , Monroe ML , Ryan PA , Falkowski A , Reeg L , Lynfield R , McMahon M , Hancock EB , Hoffman MR , McGuire S , Spina NL , Felsen CB , Gaitan MA , Lung K , Shiltz E , Thomas A , Schaffner W , Talbot HK , Crossland MT , Price A , Masalovich S , Adams K , Holstein R , Sundaresan D , Uyeki TM , Reed C , Bozio CH , Garg S . Clin Infect Dis 2025 80 (2) 461-468 ![]() BACKGROUND: Pneumonia is common in adults hospitalized with laboratory-confirmed influenza, but the association between timeliness of influenza antiviral treatment and severe clinical outcomes in patients with influenza-associated pneumonia is not well characterized. METHODS: We included adults aged ≥18 years hospitalized with laboratory-confirmed influenza and a discharge diagnosis of pneumonia over 7 influenza seasons (2012-2019) sampled from a multistate population-based surveillance network. We evaluated 3 treatment groups based on timing of influenza antiviral initiation relative to admission date (day 0, day 1, days 2-5). Baseline characteristics and clinical outcomes were compared across groups using unweighted counts and weighted percentages accounting for the complex survey design. Logistic regression models were generated to evaluate the association between delayed treatment and 30-day all-cause mortality. RESULTS: A total of 26 233 adults were sampled in the analysis. Median age was 71 years and most (92.2%) had ≥1 non-immunocompromising condition. Overall, 60.9% started antiviral treatment on day 0, 29.5% on day 1, and 9.7% on days 2-5 (median, 2 days). Baseline characteristics were similar across groups. Thirty-day mortality occurred in 7.5%, 8.5%, and 10.2% of patients who started treatment on day 0, day 1, and days 2-5, respectively. Compared to those treated on day 0, adjusted odds ratio for death was 1.14 (95% confidence interval [CI], 1.01-1.27) in those starting treatment on day 1 and 1.40 (95% CI, 1.17-1.66) in those starting on days 2-5. CONCLUSIONS: Delayed initiation of antiviral treatment in patients hospitalized with influenza-associated pneumonia was associated with higher risk of death, highlighting the importance of timely initiation of antiviral treatment at admission. |
Incidence and risk factors for invasive fungal infections in patients initiating TNF-alpha inhibitors for inflammatory bowel disease and rheumatoid arthritis
Hennessee I , Benedict K , Bahr NC , Lipner SR , Gold JAW . Clin Infect Dis 2025 80 (2) 364-366 ![]() In a commercial claims database analysis, <0.5% of patients with inflammatory bowel disease or rheumatoid arthritis developed an invasive fungal infection (IFI) within 1 year of initiating tumor necrosis factor-alpha therapy. Histoplasmosis was the most common IFI type. Overall IFI incidence varied based on region, underlying conditions, and use of certain immunosuppressive medications. |

J Infect Dis 2025 231 (2) e328-e336 ![]() ![]() BACKGROUND: Approaches for determining whether influenza vaccination prevents infection, attenuates illness, or both are important for developing improved vaccines. We estimated influenza infection incidence and evaluated symptom ascertainment methodologies in children to inform future vaccine trial design. METHODS: We conducted a prospective cohort study among children aged 6 to 23 months from May to October 2022. Study nurses collected symptom and temperature data and midturbinate nasal swabs twice weekly irrespective of symptoms; caregivers entered symptom data daily and collected nasal swabs weekly. Samples were tested for influenza with polymerase chain reaction. RESULTS: Of 230 healthy screened children, 93 were enrolled, of whom 87 (94%) completed 6-month follow-up. In total, 95% (4245/4476) of scheduled nurses, 90% (2045/2276) of caregiver swabs, 99% (92/93) of baseline blood collections, and 67% (9245/13 768) of scheduled symptom diaries were completed. Polymerase chain reaction-confirmed influenza incidence was 65% (60/93) for ≥1 infection; 11 (18%) individuals had 2 episodes and 1 (2%) had 3. Of 73 episodes, 55 (75%) had ≥1 symptom and 37 (51%) had fever (measured and/or reported). Median infection duration was 7 days (IQR, 4-9). Human RNase P gene was detected in 99% (2032/2045) of caregiver-collected swabs, through which 5 additional episodes were identified. Per episode, caregivers' diaries of reported and measured fever were 19% (25/73, 34%) and 11% (15/73, 21%) higher than nurse-reported (11/73, 15%) and nurse-measured (7/73, 10%) fever, respectively. CONCLUSIONS: The incidence of influenza infection was high and mainly symptomatic, suggesting that this platform could be suitable for future trials of vaccine efficacy and correlates of protection against infection and illness in children. |

Levy V , Branzuela A , Hsieh K , Getabecha S , Berumen R 3rd , Saadeh K , Snyder RE , Marek G , Dodson D , Newman A , Hacker JK , Kath C , Minhaj FS , Gigante CM , Gearhart S , Kallen A , Hutson CL , Jacobson K . MMWR Morb Mortal Wkly Rep 2025 74 (4) 44-49 ![]() ![]() A clade I monkeypox virus (MPXV) outbreak is ongoing in the Democratic Republic of the Congo; travel-associated clade I MPXV infections have been reported in non-African countries. In November 2024, San Mateo County Health in California identified an electronic laboratory report of polymerase chain reaction results suggestive of clade I MPXV infection in a male traveler who had recently returned from East Africa. After conferring with the California Department of Public Health (CDPH), a county health department worker visited the patient that same day at his home and obtained skin pustule swab specimens for expedited clade I MPXV testing. Clade I MPXV was confirmed the following day by the CDPH Viral and Rickettsial Disease Laboratory. This was the first reported clade I MPXV infection in the Americas. Among 83 identified contacts, five received JYNNEOS vaccine as postexposure prophylaxis. All contacts were monitored for 21 days; no secondary cases were identified. Patients with mpox-compatible lesions or clinical features should receive MPXV testing, and health care providers should immediately notify public health authorities of suspected clade I MPXV infections (e.g., mpox manifestations and travel history to an area with ongoing clade I MPXV transmission) or upon receiving a nonvariola orthopoxvirus DNA detected, clade II MPXV DNA undetectable test result to trigger additional testing and facilitate the rapid implementation of transmission-based precautions and other preventive public health interventions. |

Adler AL , Waghmare A , Smith J , Kelton M , Dickerson JA , Reed JC , Greninger AL , Kehoe L , Fairlie T , Hagen MB , Midgley CM , Lacombe K , Englund JA . Pediatr Transplant 2025 29 (2) e70050 ![]() ![]() BACKGROUND: Limited data are available regarding the development and durability of immune responses following COVID-19 infection or vaccination in pediatric solid-organ transplant (SOT) recipients. METHODS: Renal, liver, or intestinal transplant recipients < 21 years of age followed at Seattle Children's Hospital were enrolled from August 2020 to May 2021. Blood samples were collected at ~6-month intervals for up to 3 years and tested for antinucleocapsid (N) antibodies. COVID-19 vaccination data were collected from the Washington State Immunization Information System and/or the medical record. Semi-quantitative anti-S IgG testing was performed on all postvaccine samples using the Abbott Architect platform. We further evaluated a subset of postvaccine samples using variant-specific quantitative binding (Meso Scale Discovery, MSD) immunoassays and pseudovirus-neutralization assays. Antibody levels were compared over time and by vaccine category. RESULTS: We followed 83 SOT recipients for a median of 12.5 months (IQR 7.0, 28.3). Overall, 16 (19.3%) participants had evidence of SARS-CoV-2 infection based on anti-N antibody detection. Forty-six (55%) participants had a blood sample collected > 14 days after receipt of a vaccination. Serum IgG to spike antigens (anti-S antibody) increased following vaccination and increased with the number of vaccine doses received as assessed by both the Abbott and MSD assays. Neutralizing activity was significantly lower against the Omicron subvariants compared to the ancestral strain. CONCLUSION: Pediatric SOT recipients demonstrated strong antibody responses following SARS-CoV-2 vaccination, with higher anti-S antibody responses following > 2 doses of vaccine. Our study offers unique longitudinal immune response data in this vulnerable patient population. |

Lancet Reg Health - Am 2025 44 ![]() Background: Although short-term outcomes of Long COVID have been described, longer-term physical and mental health outcomes of Long COVID are less well-established. This study sought to assess differences in long-term physical and mental health outcomes extending up to three years among those with current, resolved, and no Long COVID, as well as duration of Long COVID and vaccination status. Methods: This was a prospective, multisite, study of participants with SARS-CoV-2 infection from 12/7/2020-8/29/2022, with data collected through 4/2/2024. Surveys included validated tools for physical and mental health. Data were analyzed by Long COVID status (never-had, resolved, current), Long COVID duration and vaccination status. Findings: Of 3663 participants, 2604 (71.1%) never had Long COVID, 994 (27.1%) reported current Long COVID, and 65 (1.8%) reported resolved Long COVID. Compared to never having Long COVID, current Long COVID had lower/worse scores for Patient-Reported Outcomes Measurement Information System (PROMIS) version 29 Physical (7.8; 95% confidence interval [CI] 7.3–8.3) and Mental Health (9.4; 95% CI 8.8–10.1) and higher likelihood of moderate-to-high stress (adjusted odds ratio [aOR]: 2.0; 95% CI 1.6–2.4), moderate-to-high loneliness (aOR: 1.6; 95% CI 1.4–2.0), moderate-to-severe fatigue (aOR: 3.0; 95% CI 2.5–3.7), insufficient activity (aOR for Speedy Nutrition and Physical Activity Assessment ≤4: 0.6; 95% CI 0.5–0.7; aOR for Exercise Vital Sign ≤150 min/week: 0.7, 95% CI 0.6–1.0), and worse dyspnea (aOR: 5.0; 95% CI 4.3–5.8). Resolved Long COVID had lower scores for PROMIS Physical by 2.0 (95% CI 0.2–3.8) and Mental Health by 2.3 (95% CI 0.2–4.4) than the never-had-Long COVID cohort. Number of COVID-19 vaccinations was associated with better outcomes across all measures. Interpretation: Among participants followed up to 3 years after initial infection, those with current Long COVID had worse physical and mental health outcomes. The majority of those with Long COVID did not resolve, with less than 2% having resolved Long COVID. The resolved Long COVID cohort had moderately worse physical and mental health compared with those never-having-Long COVID. COVID-19 vaccination was associated with better outcomes.

Differentiated community-based point-of-care early infant diagnosis to improve HIV diagnosis and ART initiation among infants and young children in Zambia: a quasi-experimental cohort study
Manasyan A , Tembo T , Dale H , Pry JM , Itoh M , Williamson D , Kapesa H , Derado J , Beard RS , Iyer S , Gass S , Mwila A , Herce ME . BMJ Glob Health 2025 10 (2) ![]() INTRODUCTION: An estimated 800 000 children (<15 years) globally living with HIV remain undiagnosed. To reach these children with timely HIV testing services during infancy, we implemented a community-based differentiated care model using mobile point-of-care (POC) technology for early infant diagnosis (EID) of HIV, and assessed its effects on EID positivity, antiretroviral therapy (ART) initiation and 3-month retention in care. METHODS: Between 1 June 2019 and 31 May 2020 at six health facilities in Lusaka, Zambia, we enrolled mother-infant pairs (MIPs) at high risk for vertical transmission of HIV based on missing or late infant EID testing or other maternal risk factors. We offered these MIPs community POC EID testing (post-intervention), and compared their outcomes to historical high-risk controls at the same sites (1 June 2017-31 May 2018; pre-intervention). We used propensity score matched weighting and mixed effects regression modelling to estimate outcome differences pre-intervention and post-intervention, and to identify MIP characteristics predictive of vertical transmission of HIV. RESULTS: 2577 MIPs were included in the analysis: 1763 and 814 high-risk MIPs from the pre-intervention and post-intervention periods, respectively. Infant HIV positivity was significantly higher in the post-intervention (2.2%) vs pre-intervention (1.1%) period (p=0.038), however this difference was attenuated (0.83%, 95% CI: -0.50%, 2.15%) after adjusting for differences in maternal age, maternal antenatal care visits, infant birth month and facility. During the post-intervention period, MIPs where the mother disengaged from care were 12.97 (95% CI: 2.41, 69.98) times as likely to have an infant diagnosed with HIV vs those in which the infant received late EID testing without maternal care disengagement. Among 18 infants diagnosed with HIV by the intervention, 16 (88.9%) initiated same-day ART and all continued ART at 3-month follow-up. CONCLUSION: Community-based differentiated care employing POC EID technology increased testing positivity in unadjusted analyses, and resulted in high ART initiation and early care retention, suggesting it may be a promising approach for reaching infants and young children living with HIV being missed by current facility-based approaches. TRIAL REGISTRATION NUMBER: This trial is registered under the following Clinicaltrials.gov Identifier: NCT03133728. |
Highly pathogenic avian influenza A(H5N1) virus infection of indoor domestic cats within dairy industry worker households - Michigan, May 2024
Naraharisetti R , Weinberg M , Stoddard B , Stobierski MG , Dodd KA , Wineland N , Beal M , Morse J , Hatter S , Sledge D , Youatt K , Coyle J , McFadden J , Uyeki TM , Durand LO . MMWR Morb Mortal Wkly Rep 2025 74 (5) 61-65 ![]() ![]() Highly pathogenic avian influenza (HPAI) A(H5N1) virus, clade 2.3.4.4b, genotype B3.13 infection has been documented in cats on U.S. dairy cattle farms. In May 2024, the detection of HPAI A(H5N1) virus infection in two cats that were reported to be exclusively indoor, and that had respiratory and neurologic illness in different households, prompted an investigation by the Michigan Department of Health and Human Services and Mid-Michigan District Health Department (MDHHS/MMDHD). The cats' owners and household members were interviewed and offered testing for influenza A(H5) virus. The owner of one cat worked on a dairy farm but declined A(H5) testing; three other household members received negative A(H5) test results. The owner of the other cat lived alone and worked on multiple dairy farms transporting unpasteurized milk; this worker also reported getting splashed in the face and eyes by unpasteurized milk but declined A(H5) testing. Both workers were employed in a county known by MDHHS/MMDHD to have HPAI A(H5N1) virus, clade 2.3.4.4b, genotype B3.13-positive dairy cattle. In states with confirmed HPAI A(H5N1) in livestock, veterinary care can be aided if veterinarians obtain household members' occupational information, especially when evaluating cats with signs of respiratory or neurologic illness. If occupational exposure to HPAI A(H5N1)-infected livestock is identified among cat owners, and their companion cats are suspected to have HPAI A(H5N1) virus infection, it is important that veterinarians contact state and federal public health and animal health officials to collaborate on joint One Health investigations and testing to protect human and animal health. |

Cyclospora genotypic variations and associated epidemiologic characteristics, United States, 2018-2021
Shen J , Cama VA , Jacobson D , Barratt J , Straily A . Emerg Infect Dis 2025 31 (2) 256-266 ![]() ![]() Seasonal cyclosporiasis outbreaks occur in the United States every year. To better understand the disease, the Centers for Disease Control and Prevention developed a novel genotyping system that successfully clusters nonclonal eukaryotes. We examined temporal-geographic distributions of Cyclospora cluster consensus genotypes (CCGs) and applied regression analyses to identify correlations between Cyclospora spp. parasites and clinical manifestations or epidemiologic risk factors, using data collected during 2018-2021. No CCG was uniquely associated with or consistently detected in a state during the study, suggesting that cyclosporiasis in the United States is likely caused by frequent parasite introductions. We identified positive associations between infection with C. ashfordi and C. cayetanensis and consumption of specific produce items: cilantro, mango, and onion for C. ashfordi and iceberg lettuce, carrot, and cauliflower for C. cayetanensis. Our findings can guide future research into public health interventions aimed at reducing the burden of cyclosporiasis in the United States. |
Association of infection-induced antibody levels with risk of subsequent SARS-COV-2 reinfection among healthcare professionals, Rhode Island, 1 March 2020-17 February 2021
Shi J , Gabriel MG , Epperson M , Chan PA , Jones JM , Petersen LR , Briggs Hagen M , Thornburg NJ , Saydah S , Midgley CM . Microbiol Spectr 2025 e0208624 ![]() Numerous studies have investigated vaccine-induced correlates of protection (CoP) against severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) infection, but data on infection-induced CoP are limited. Given differences between vaccine- and infection-induced immune responses, in conjunction with low vaccination in many US populations, a better understanding of infection-induced CoP is needed. We used residual sera from a mid-2020 Rhode Island serosurvey of healthcare professionals (HCP) and corresponding state-collected SARS-CoV-2 testing data through February 2021 to generate an analytic cohort of HCP with a first SARS-CoV-2 infection prior to serosurvey blood collection and multiple viral tests after blood collection to assess for reinfection (defined as a positive viral test ≥90 days after their first positive). We tested sera for levels of IgG and IgA targeting ancestral spike (S), receptor-binding domain (RBD), or nucleocapsid (N). We used adjusted Cox proportional hazard ratios to assess the association between categorical antibody level and the risk of subsequent reinfection. Among 170 HCP included in this analysis (median age = 47 years; interquartile range: 35-55 years), 30 were reinfected during the analytic period. Adjusted Cox proportional hazard ratios indicated that higher levels of anti-S or anti-RBD IgG were significantly associated with a lower risk of reinfection. These findings support the use of anti-S or anti-RBD IgG levels as markers of immunologic protection, such as in population serosurveys, or immune-bridging studies in settings of high prevalence of prior infection.  IMPORTANCEThe measurement of antibodies in blood is a relatively simple process and commonly used to estimate overall levels of past infection in populations. But, if someone has antibodies, does this mean that they are protected from being infected again? And are people with higher levels of antibody better protected? There are good data in the literature exploring how antibodies from the coronavirus disease 2019 (COVID-19) vaccination are associated with protection. But, there is still a lot to learn about protection conferred by antibodies that develop after a severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) infection. In our study, we measure the levels of six different antibody types developed after infection and compare levels to the risk of subsequent infection to better understand which antibody types are best associated with protection. Our data are important for improving studies that use antibodies as proxies for protection, such as population immunity estimates, or those assessing new prevention products. |
Risk period for transmission of SARS-CoV-2 and seasonal influenza: a rapid review
Stone EC , Okasako-Schmucker DL , Taliano J , Schaefer M , Kuhar DT . Infect Control Hosp Epidemiol 2025 1-9 ![]() ![]() BACKGROUND: Restricting infectious healthcare workers (HCWs) from the workplace is an important infection prevention strategy. The duration of viral shedding or symptoms are often used as proxies for the infectious period in adults but may not accurately estimate it. OBJECTIVE: To determine the risk period for transmission among previously healthy adults infected with SARS-CoV-2 omicron variant (omicron) or influenza A (influenza) by examining the duration of shedding and symptoms, and day of symptom onset in secondary cases of transmission pairs. DESIGN: Rapid review. METHODS: This rapid review adhered to PRISMA-ScR; five databases were searched. The cumulative daily proportion of participants with an outcome of interest was calculated for each study and summarized. RESULTS: Forty-three studies were included. Shedding resolved among ≥ 70% of participants by the end of day nine post symptom onset for omicron, and day seven for influenza; and for ≥ 90% of participants, by the end of day 10 for omicron and day nine for influenza. Two studies suggested shedding continues > 24 hours post-fever resolution for both viruses. Symptom onset occurred in ≥ 80% of secondary cases by the end of day seven post-primary case symptom onset for omicron and day six for influenza. CONCLUSIONS: Omicron shedding is consistent with previous recommendations to exclude infected HCWs from work for 10 days; and influenza follows a similar trend. Earlier symptom onset in most secondary cases for both pathogens indicates that, despite persistent viral shedding, most transmission occurs earlier; and the cumulative serial interval might better approximate the duration of infectiousness. |

Malar J 2025 24 (1) 53 ![]() BACKGROUND: Monitoring insecticide levels and physical integrity over time is essential for assessing the durability of insecticide-treated nets (ITNs), which largely depends on the net handling habits of users. This study determined the insecticide content and effectiveness of ITNs (Yorkool and PermaNet 2.0) at 6, 12, 24, and 36 months after a mass distribution campaign in Mali. METHODS: At 6 months (May, 2018), 12 months (December, 2018), 24 months (November-December, 2019), and 36 months (November-December, 2020), 30 nets were randomly collected from households in the districts of Kenieba and Kita in the southern part of Mali, together with information about ITN use and washing practices. The insecticidal effectiveness of the ITNs was assessed with the World Health Organization (WHO) cone test using a laboratory-reared, susceptible colony of Anopheles coluzzii. The residual insecticide content was measured by a nondestructive sampling technique with a portable field-adapted high-performance liquid chromatographic (HPLC) system (C-Vue®) validated by running samples in parallel with standardized WHO HPLC methods. RESULTS: At each survey time, nets were washed an average of three times over the previous 6 months, most commonly using Local soaps containing sodium hydroxide, detergent, or bleach. Using HPLC_CVue, the average deltamethrin concentration was 55 mg/m(2) at 6 months and gradually decreased to 14 mg/m(2) at 36 months for Yorkool nets. The values for the PermaNet 2.0 nets were 45 mg/m(2) at 6 months and 6 mg/m(2) at 36 months. Until the 24-month evaluation, the proportion of nets with minimal effectiveness was greater than 80% for both net types and sites. At 24 and 36 months, less than 80% of nets from both products and sites met the WHO optimal effectiveness criteria. CONCLUSION: The WHO standardized cone test and C-Vue evaluation demonstrated that net type effectiveness and insecticide content were consistently lower than expected at 3 years, and users washed nets with local soaps containing sodium hydroxide, detergent or bleach. The C-Vue portable chromatographic device was used successfully for the first time in Mali to measure the insecticide concentration of ITNs. |

Alcover KC , McAdam J , Denic-Roberts H , Byrne C , Sjodin A , Davis M , Jones R , Zhang Y , Rusiecki JA . Int J Hyg Environ Health 2025 265 114540 ![]() OBJECTIVES/BACKGROUND: We evaluated patterns of serum concentrations of endocrine disrupting chemicals (EDCs), namely polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), and polybrominated diphenyl ethers (PBDEs), in a U.S. military sample by race/ethnicity (R/E) and sex. METHODS: Twenty-three EDCs were measured in stored serum samples obtained between 1995 and 2010 for 708 service members from the Department of Defense Serum Repository. For each EDC, geometric means (GM) were estimated using log-transformed concentrations in a linear regression model, for eight combined R/E/sex groups: non-Hispanic White (NHW), non-Hispanic Black (NHB), non-Hispanic Asian (NHA), and Hispanic men and women, adjusted for age and service branch and stratified by age tertile ("younger age": 17-23, "middle age": 24-30, and "older age": 31-52 years). Comparisons were made between our military sample and the National Health and Nutrition Examination Survey (NHANES) 2003-2004 data for NHW and NHB groups. RESULTS: Within our military sample, the highest PCB concentrations were among older age NHB men and women and highest OCP concentrations among older age NHB women and NHA men. PBDE concentrations were generally highest in middle age Hispanic women and NHA men, though based on small sample size. Generally, NHB men and women had higher concentrations of EDCs in both the military and NHANES. CONCLUSIONS: We found patterns of elevated EDC concentrations among NHB, NHA, and Hispanic groups in the military sample and for NHB men and women in NHANES. There were no consistent patterns of higher or lower EDCs comparing the military to NHANES. Future studies of EDCs and health outcomes should stratify by R/E/sex to account for potential disparities in EDC concentrations. |
Improving volatile organic compound exposure assessment using biomonitoring by relating exposure biomarker levels in blood and urine
Chambers DM , Roberson BJ , Woodruff CA , Blount BC , Bhandari D . Chem Res Toxicol 2025 ![]() Exposure assessment of hazardous volatile organic compounds (VOCs) requires accurate quantification of internal dose when establishing limits or identifying significant differences within and among populations. Even though accurate internal dose can be directly measured in blood, it is not always practical or possible to collect a suitable blood specimen. This work studies the relationship between blood and urine levels for certain smoke biomarkers (e.g., tobacco, marijuana) measured in self-reported cigarette smokers. Urine and blood specimens were collected as matched pairs from individuals at the same time. We used our latest specimen collection and VOC analysis protocols to minimize sample collection, handling, and analysis biases. From these analyses, unmetabolized urine benzene, furan, 2,5-dimethylfuran, isobutyronitrile, and benzonitrile levels were found to trend with blood levels. In addition, we measured urine creatinine levels, which were found to be significantly associated with all blood analyte concentrations (p-value ranging from <0.0063 to <0.0001) except for isobutyronitrile (p = 0.3347). For the analytes that were associated with urine creatinine levels, the ratios of urine-to-blood concentrations were substantially higher than those predicted from the urine/blood partition coefficients (K(urine/blood)), which should occur if VOCs can freely equilibrate (i.e., passive diffusion) between the blood and urine. The urine isobutyronitrile concentration, which was the only analyte that was not associated with the urine creatinine level, had a urine-to-blood ratio similar to K(urine/blood). These results suggest either that urine VOC levels for certain VOCs do not equilibrate with blood levels in the urinary tract or that there is a conversion of conjugated to free forms, increasing urine VOC levels. Nevertheless, these deviations from partition theory (e.g., Henry's Law) are analyte-specific and require characterization to establish a relationship between blood and urine levels. |
Expert panel on monitoring radiation doses from recurrent medical diagnostic procedures: Sixth Gilbert W. Beebe Webinar
Frush DP , Ansari A , Brink JA , Kosti O , Larson DB , Linet MS , Mahesh M , Sechopoulos I , Vassileva J . J Appl Clin Med Phys 2025 e70022 ![]() ![]() Recurrent imaging is an essential tool for patient care but with an attendant dose from radiation exposure. Recurrent imaging has been the subject of increasing scrutiny and debate based largely on the risk from increasing cumulative doses. However, the accountability for and actions with recurrent imaging as a special component in the general construct of radiation protection in medicine is unclear. This is demonstrated by the perspectives provided by the various imaging community experts. Some perspectives may be different, but many share a common ground. Understanding these various perspectives illustrates the wide-ranging optics in considering benefits and costs in the recurrent imaging paradigm and, moreover, the value in pursuing multi-stakeholder-derived harmonization for recurrent imaging and radiation dose. This move towards consensus would be to the benefit of the imaging community, referrers, and other related healthcare professionals, as well as patients, their caregivers, and the public. |
The trade-offs between wildfires and prescribed fires: A case study for 2016 Gatlinburg wildfires
Li Z , Vaidyanathan A , Maji KJ , Hu Y , O'Neill SM , Russell AG , Odman MT . ACS EST Air 2025 2 (2) 236-248 ![]() Prescribed burning is an effective land management tool that provides a range of benefits, including ecosystem restoration and wildfire risk reduction. However, prescribed fires, just like wildfires, introduce smoke that degrades air quality. Furthermore, while prescribed fires help manage wildfire risk, they do not eliminate the possibility of wildfires. It is therefore important to also evaluate fire and smoke impacts from wildfires that may occur after a prescribed burn. In this study, we developed a framework for understanding the air quality and health related trade-offs between wildfires and prescribed fires by simulating a set of counterfactual scenarios including wildfires, prescribed fires, and postprescribed burn wildfires. We applied this framework to the case of the Gatlinburg wildfire and found that emissions from prescribed burns and subsequent wildfire were slightly lower than those from the wildfire itself. This reduction resulted in lower daily average concentrations and exposures of PM(2.5), O(3), and NO(2). Even considering the possibility of a postprescribed burn wildfire, prescribed fires reduced population-weighted daily average PM(2.5), daily maximum 8-h average O(3), and 1-h maximum NO(2) concentrations. In Sevier County, Tennessee where the wildfire occurred, these reductions reached 5.28 μg/m(3), 0.18 ppb, and 1.68 ppb, respectively. The prescribed fires also reduced the person-days smoke exposures from the wildfire. Our results suggest that although prescribed fires cannot eliminate the air quality impacts of wildfires, they can greatly reduce smoke exposure in downwind areas distant from the burn sites. |
Effectiveness of educational and psychological messaging interventions to improve safe fish consumption knowledge and behaviors among Asian women of childbearing age
Polter E , Haban A , Meiman J , Tomasallo C . WMJ 2024 123 (6) 537-541 ![]() BACKGROUND: We evaluated the effectiveness of an intervention to reduce contaminant exposure from fish consumption among Asian women of childbearing age residing in the Milwaukee, Wisconsin, area. METHODS: Women of childbearing age were randomized to group 1, no intervention; group 2, educational messaging only; or group 3, educational messaging plus a motivational self-affirmation component. Then, we compared safe fish consumption knowledge, intentions, and behaviors among groups. RESULTS: Among 123 participants, groups 2 and 3 were more likely than group 1 to report "eating fewer fish meals" to reduce exposure to contaminants (group 2 odds ratio [OR] 1.42; 95% CI, 0.59-3.44; group 3 OR 2.76; 95% CI, 1.12-7.03). DISCUSSION: Self-affirmation messaging can enhance educational messaging to increase safe fish consumption among Asian women of childbearing age. |
Fish consumption advisory awareness and behavior among Asian women of childbearing age - Milwaukee, Wisconsin, January 1, 2022-January 31, 2023
Polter EJ , Schinwald M , Haban A , Meiman J , Tomasallo C . WMJ 2024 123 (6) 521-527 ![]() INTRODUCTION: Asian persons in the Milwaukee, Wisconsin, area might be more susceptible to contaminant exposure because of high consumption of local sportfish and store-purchased fish. This is a particular risk to women who are pregnant or might become pregnant and breastfeeding women because of health risks to the developing fetus or child's neurological system. METHODS: We conducted a survey among women of childbearing age from 4 Asian ethnic groups (Hmong, Karen, Chinese, and Filipino) residing in the Milwaukee area to assess self-reported fish consumption from different sources, fish preparation behaviors, fish consumption behaviors during pregnancy and breastfeeding, and awareness of local and national fish consumption advisories and limits. RESULTS: Participants included 153 women aged 18 to 50 years. Seventy-one (46%) had consumed ≥1 sport-caught or store-purchased species at levels above a local, state, or federal advisory. Participants reported consuming a median of 11 Wisconsin sportfish and 24 store-purchased fish meals each year. Approximately half of participants reported reducing fish consumption or changing fish preparation methods to avoid contaminants. Overall, 62 (41%) were aware of any fish consumption advisory. CONCLUSIONS: Self-reported fish consumption habits among certain Hmong, Karen, Chinese, and Filipino women of child-bearing age were higher than local, state, or federal advisories, and approximately half of participants self-reported awareness of local or federal fish consumption advisories. Reaching Asian diaspora communities with culturally appropriate educational materials regarding safe fish consumption might help reduce contaminant exposure. |

National surveillance of human ehrlichiosis caused by Ehrlichia ewingii, United States, 2013-2021
Adams SN , Bestul NC , Calloway KN , Kersh GJ , Salzer JS . Emerg Infect Dis 2025 31 (2) 222-227 ![]() ![]() Human ehrlichiosis is a potentially fatal tickborne disease caused by 3 species: Ehrlichia chaffeensis, E. ewingii, and E. muris eauclairensis. In the United States, 234 confirmed cases of E. ewingii ehrlichiosis were reported to the Centers for Disease Control and Prevention through the National Notifiable Diseases Surveillance System during 2013-2021; average annual incidence was 0.08 cases/1 million population. E. ewingii ehrlichiosis was reported more commonly among older, White, non-Hispanic, and male patients. Incidence and case counts generally increased yearly, except for 2020 and 2021. The highest number of cases were reported from Missouri and Arkansas. We report the geographic expansion of E. ewingii ehrlichiosis and the continued public health challenge of clarifying clinical manifestations of this infection. Clinician education will be essential to implement molecular assays to properly diagnose E. ewingii infection in patients and gain a better understanding of the epidemiology of this emerging disease. |

BMJ Glob Health 2025 10 (2) ![]() Investigating acute respiratory illnesses (ARIs) is difficult due to non-specific symptoms, varied health-seeking behaviors, and resource limitations; yet early detection is critical to global health security. Kenya's Ministry of Health (MOH) uses the Integrated Disease Surveillance strategy for public health surveillance, incorporating event-based surveillance (EBS) and indicator-based surveillance (IBS) for early warning system. MOH, supported by the US-CDC, established Influenza Sentinel Surveillance (ISS) in 2006 and later launched community EBS (CEBS) and health facility EBS (HEBS) pilots to enhance surveillance for COVID-19. On March 2, 2021, the CEBS system detected a signal of "Two or more people presenting with similar signs and symptoms in a community within a week" in a county. Investigations launched on March 4, 2021, investigations revealed unreported ARI cases which had been missed by both the ISS and IBS. A total of 176 ARI cases were line-listed with 91/176 (51.7%) aged <5-years and 46/176 (26.1%) hospitalized. RT-PCR tests confirmed 34/79 (43.0%) SARS-CoV-2 and 1/7 (14.3%) A/H3N2 cases. Of the CEBS, HEBS, IBS, and ISS systems deployed by the county to strengthen the early warning for respiratory diseases, CEBS detected a signal of unreported ARIs that facilitated further investigations and response. |
Salmonella serotypes in the genomic era: simplified Salmonella serotype interpretation from DNA sequence data
Deng X , Li S , Xu T , Zhou Z , Moore MM , Timme R , Zhao S , Lane C , Dinsmore BA , Weill F , Fields PI . Appl Environ Microbiol 2025 e0260024 ![]() ![]() In the era of genomic characterization of strains for public health microbiology, whole genome sequencing (WGS)-enabled subtyping of Salmonella provides superior discrimination of strains compared to traditional methods such as serotyping. Nonetheless, serotypes are still very useful; they maintain historical continuity and facilitate clear communication. Genetic determination of serotypes from WGS data is now routine. Genetic determination of rarer serotypes can be problematic due to a lack of sequences for rare antigen types and alleles, a lack of understanding of the genetic basis for some antigens, or some inconsistencies in the White-Kauffmann-Le Minor (WKL) Scheme for Salmonella serotype designation. Here, we present a simplified interpretation of serotypes to address the shortcomings of genetic methods, which will allow the streamlined integration of serotype determination into the WGS workflow. The simplification represents a consensus perspective among major U.S. public health agencies and serves as a WGS-oriented interpretation of the WKL Scheme. We also present SeqSero2S, a bioinformatics tool for WGS-based serotype prediction using the simplified interpretation.IMPORTANCEThe utility of Salmonella serotyping has evolved from a primary subtyping method, where the need for strain discrimination justified its complexity, to a supplemental subtyping scheme and nomenclature convention, where clarity and simplicity in communication have become important for its continued use. Compared to phenotypic methods like serotyping, whole genome sequencing (WGS)-based subtyping methods excel in recognizing natural populations, which avoids grouping together strains from different genetic backgrounds or splitting genetically related strains into different groups. This simplified interpretation of serotypes addresses a shortcoming of the original scheme by combining some serotypes that are known to be genetically related. Our simplified interpretation of the White-Kauffmann-Le Minor (WKL) Scheme facilitates a complete and smooth transition of serotyping's role, especially from the public health perspective that has been shaped by the routine use of WGS. |

Carry MG , Soelaeman RH , Aluko-Estrella SK , Garcia-Williams AG , West LK , Haston JC , Besrat BN , Aponte J , Jones SL , Rutt CD . Health Behav Policy Rev 2024 11 (6) 1770-1782 ![]() Objective: Schools’ ability to implement recommended hygiene-related activities is critical in preventing the spread of gastrointestinal and respiratory illness. We conducted this study to improve understanding of perceived barriers to, and responsibility for implementing recommended activities related to hand hygiene, cleaning, and disinfection. Methods: We recruited a convenience sample of adults affiliated with the National Parent Teacher Association during July-August 2020. Questions focused on barriers to implementing recommended hygiene-related, cleaning, and disinfection activities. Results: Overall, 1173 participants completed the survey. Among caregivers, the main barriers to conducting hand hygiene were educators’ ability to monitor students (72%), lack of time (66%), and limited funding for hygiene supplies (65%). Among educators, the main barriers to conducting hand hygiene were access to needed supplies (75%), ability to monitor students (75%), and lack of time (72%). The top barriers reported by both groups relating to cleaning and disinfection activities were similar, with both groups reporting limited staff capacity (61% vs 75%), lack of time/scheduling difficulties (64% vs 75%), and lack of funds to purchase supplies (64% vs 70%). Conclusions: Our results clarify stakeholder concerns around implementation and main barriers. To implement recommended activities, schools need support (funding, staff, and supplies) and guidance for hygiene-related activities. © 2024, Paris Scholar Publishing. All rights reserved. |
Multiple behaviors associated with HIV risk among female sex workers and men who have sex with men: Results from pooled respondent-driven sampling (RDS) surveys - Uganda, 2021-2023
Chapman KS , Tumusinze G , Gutreuter S , Arons M , Ogwal M , Aluzimbi G , Mutunzi R , Nakabugo F , Fitzmaurice AG , Musinguzi G , Hladik W . AIDS Behav 2025 ![]() Key populations (KP), such as female sex workers (FSW) and men who have sex with men (MSM) can engage in multiple behaviors associated with HIV risk, but they are typically categorized by a single defining behavior, i.e., selling sex and sex with a man, respectively. We estimated the prevalence of engaging in multiple KP defining behaviors such as buying/selling sex, receptive anal sex, and injection drug use (IDU) among KP in Uganda. Data were collected at survey offices in four sites (Kampala, Jinja, Mbarara, and Masaka) through respondent-driven sampling. Data across multiple sites were combined and reweighted based on the combined sample size for each population. We fitted weighted multinomial logistic models for additional KP defining behaviors using demographics as predictors, and the simplest plausible model was identified for each KP using the Bayesian Information Criterion. Among FSW and sexually exploited minors under 18 years of age, 21.8% (CI: 20.1-23.5%) ever engaged in anal sex and 12.0% (CI: 10.6-13.3%) ever engaged in IDU in our model. Among MSM, 54.8% (CI: 52.0-57.7%) ever engaged in buying/selling sex and 11.0% (CI: 9.3-12.8%) ever engaged in IDU in the model. While KP are generally viewed as independent groups, our findings demonstrate that KP defining behaviors such as buying/selling sex, anal sex with a man, and IDU are shared across populations, with buying/selling sex particularly common among MSM. Consideration of comprehensive behaviors by outreach and service providers may better inform HIV risk reduction and prevention services for key populations. |
Health and economic impact of COVID-19 surveillance testing in seattle homeless shelters: A cost-effectiveness analysis
Cox SN , Chow EJ , Rolfes MA , Mosites E , Sharma M , Chu HY , Zimmermann M . AJPM Focus 2025 4 (2) ![]() Introduction: COVID-19 surveillance in congregate settings is important to mitigating disease, but the health and economic impact of testing remains unclear. Methods: The authors developed a Markov model to project the cost-utility of COVID-19 testing strategies in homeless shelters from the healthcare payer and societal perspective over 1 year. Model inputs utilized data from residents aged ≥18 years across 23 Seattle shelters from January 1, 2020, to May 31, 2021. No in-shelter surveillance was compared with scenarios of 2 COVID-19 testing strategies implemented monthly: polymerase chain reaction (PCR) testing and rapid antigen testing; scenarios in which only PCR testing was available were also evaluated. The primary health outcome was quality-adjusted life years. Interventions were considered cost-effective if the incremental cost-effectiveness ratio was ≤$150,000 per quality-adjusted life year and dominant if they saved costs and provided health effects. Results: When assuming the availability of both antigen and PCR tests, most rapid antigen testing strategies were cost-effective, whereas PCR testing was dominated by antigen testing. Compared with no in-shelter surveillance, antigen testing increased mean quality-adjusted life years by 0.0009 (0.03% infections averted) at an incremental cost of $97/resident from the healthcare perspective (incremental cost-effectiveness ratio=$112,352/quality-adjusted life year gained) and $8/resident from the societal perspective (incremental cost-effectiveness ratio=$9,627/quality-adjusted life year gained) at 75% vaccination coverage. PCR testing was not cost-effective when antigen testing was available but was cost-effective compared with no surveillance at low vaccination coverage levels (<30% coverage from the healthcare perspective and ≤48% coverage from the societal perspective). Probabilistic sensitivity analysis showed that antigen testing was cost-effective in 62% and 86% of simulations from the healthcare and societal perspectives, respectively. Conclusions: Modeled findings show that COVID-19 testing in shelters can be a cost-effective pandemic response. Antigen testing remained cost-effective at high vaccination levels, whereas PCR testing was most effective at low vaccination levels if antigen testing was not available. © 2024 The Author(s) |

Meningococcal vaccination in the United States: Past, present, and future
Schillie S , McNamara LA . Paediatr Drugs 2025 ![]() Meningococcal disease is rare but serious, often striking previously healthy adolescents or young adults, with substantial morbidity and mortality. The incidence of meningococcal disease in the USA declined even prior to the issuance of routine recommendations for vaccination, although an uptick in incidence has occurred since 2022. Routine recommendations for adolescent MenACWY vaccination were issued in 2005, and recommendations for adolescent MenB vaccination based on shared clinical decision-making (SCDM) were issued in 2015. Although meningococcal vaccines are safe and effective, their limited duration of protection coupled with low disease incidence result in a high cost per case averted by vaccination, most notably with MenB vaccines. The low cost-effectiveness raises ethical concerns about resource use and the role of economic analyses in policy decisions. However, the potential for substantial public health impact remains. Outer membrane vesicle (OMV)-containing MenB vaccines provide some protection against gonorrhea infections. The recent development of pentavalent ABCWY vaccines provide the opportunity to reduce the number of injections and simplify implementation, provided MenACWY and MenB vaccine schedules are harmonized. Vaccine attributes, implementation issues, and resource utilization will be important considerations in optimization of the US adolescent meningococcal vaccination strategy. |

JAMA Netw Open 2025 8 (2) e2459672 ![]() IMPORTANCE: An estimated 1% to 3% of children with SARS-CoV-2 infection will develop post-COVID-19 condition (PCC). OBJECTIVE: To evaluate the odds of PCC among children with COVID-19 vaccination prior to SARS-CoV-2 infection compared with odds among unvaccinated children. DESIGN, SETTING, AND PARTICIPANTS: In this case-control study, children were enrolled in a multisite longitudinal pediatric cohort from July 27, 2021, to September 1, 2022, and followed up through May 2023. Analysis used a case (PCC reported)-control (no PCC reported) design and included children aged 5 to 17 years whose first real time-polymerase chain reaction (RT-PCR)-confirmed SARS-CoV-2 infection occurred during the study period, who were COVID-19 vaccine age-eligible at the time of infection, and who completed a PCC survey at least 60 days after infection. From December 1, 2022, to May 31, 2023, children had weekly SARS-CoV-2 testing and were surveyed regarding PCC (≥1 new or ongoing symptom lasting ≥1 month after infection). EXPOSURES: COVID-19 mRNA vaccination status at time of infection was the exposure of interest; participants were categorized as vaccinated (≥2-dose series completed ≥14 days before infection) or unvaccinated. Vaccination status was verified through vaccination cards or vaccine registry and/or medical records when available. MAIN OUTCOME AND MEASURES: Main outcomes were estimates of the odds of PCC symptoms. Multivariate logistic regression was performed to estimate the odds of PCC among vaccinated children compared with odds of PCC among unvaccinated children. RESULTS: A total of 622 participants were included, with 28 (5%) case participants and 594 (95%) control participants. Median (IQR) age was 10.0 (7.0-11.9) years for case participants and 10.3 (7.8-12.7) years for control participants (P = .37). Approximately half of both groups reported female sex (13 case participants [46%] and 287 control participants [48%]). Overall, 57% of case participants (16 children) and 77% of control participants (458 children) were vaccinated (P = .05). After adjusting for demographic characteristics, number of acute COVID-19 symptoms, and baseline health, COVID-19 vaccination was associated with decreased odds of 1 or more PCC symptom (adjusted odds ratio [aOR], 0.43; 95% CI, 0.19-0.98) and 2 or more PCC symptoms (aOR, 0.27; 95% CI, 0.10-0.69). CONCLUSIONS AND RELEVANCE: In this study, mRNA COVID-19 vaccination was associated with reduced odds of PCC in children. The aORs correspond to an estimated 57% and 73% reduced likelihood of 1 or more and 2 or more PCC symptoms, respectively, among vaccinated vs unvaccinated children. These findings suggest benefits of COVID-19 vaccination beyond those associated with protection against acute COVID-19 and may encourage increased pediatric uptake. |
Content analysis of social determinants of health accelerator plans using artificial intelligence: A use case for public health practitioners
DePriest K , Feher J 3rd , Gore K , Glasgow L , Grant C , Holtgrave P , Hacker K , Chew R . J Public Health Manag Pract 2025 ![]() ![]() CONTEXT: Public health practice involves the development of reports and plans, including funding progress reports, strategic plans, and community needs assessments. These documents are valuable data sources for program monitoring and evaluation. However, practitioners rarely have the bandwidth to thoroughly and rapidly review large amounts of primarily qualitative data to support real-time and continuous program improvement. Systematically examining and categorizing qualitative data through content analysis is labor-intensive. Large language models (LLMs), a type of generative artificial intelligence (AI) focused on language-based tasks, hold promise for expediting content analysis of public health documents, which, in turn, could facilitate continuous program improvement. OBJECTIVES: To explore the feasibility and potential of using LLMs to expedite content analysis of real-world public health documents. The focus was on comparing semiautomated outputs from GPT-4o with human outputs for abstracting and synthesizing information from health improvement plans. DESIGN: Our study team conducted a content analysis of 4 publicly available community health improvement plans and compared the results with GPT-4o's performance on 20 data elements. We also assessed the resources required for both methods, including time spent on prompt engineering and error correction. MAIN OUTCOME MEASURES: Accuracy of data abstraction and time required. RESULTS: GPT-4o demonstrated abstraction accuracy of 79% (n = 17 errors) compared to 94% accuracy by the study team for individual plans, with 8 instances of falsified data. Out of the 18 synthesis data elements, GPT-4o made 9 errors, demonstrating an accuracy of 50%. On average, GPT-4o abstraction required fewer hours than study team abstraction, but resource savings diminished when accounting for time for developing prompts and identifying/correcting errors. CONCLUSIONS: Public health professionals who explore the use of generative AI tools should approach the method with cautious curiosity and consider the potential tradeoffs between resource savings and data accuracy. |

The association between HI and age at ALS diagnosis was assessed using multivariate analysis. Results: Of the 3424 respondents, 56.6% had experienced a HI. The adjusted odds ratio (aOR) for an ALS diagnosis before age 60 years for patients with a HI was 1.24 (95% CI, 1.07-1.45). One or two HIs had an aOR of 1.15 (95% CI, 0.97-1.36), and five or more HIs had an aOR of 1.58 (95% CI, 1.19-2.09). HI before age 18 years yielded an aOR of 2.03 (95% CI, 1.53-2.70) as well as HI between the ages of 18 and 30 years (aOR = 1.48, 95% CI: 1.06-2.06)). When narrowing the analysis to patients with HI before age 18 compared with patients with no HI, we found an association with HI that led to an emergency department or hospital visit (aOR = 1.50 (95% CI: 1.21-1.86)). Conclusions: In this cross-sectional analysis of ALS patients, HIs occurring in childhood and early adulthood and the number of HIs increased the odds of being diagnosed before age 60 years. These results suggest that HI continues to be a risk factor for ALS and could be associated with a younger age of diagnosis. |
Interior-point methods for monotone linear complementarity problems based on the new kernel function with applications to control tabular adjustment problem
Lesaja G , Oganian A , Williams T , Iacob I , Iqbal M . Stat Optim Inf Comput 2025 13 (3) 900-921 ![]() We present a feasible kernel-based interior point method (IPM) to solve the monotone linear complementarity problem (LCP) which is based on an eligible kernel function with a new logarithmic barrier term. This kernel function defines the new search direction and the neighborhood of the central path. We show the global convergence of the algorithm and derive the iteration bounds for short- and long-step versions of the algorithm. We applied the method to solve a continuous Control Tabular Adjustment (CTA) problem which is an important Statistical Disclosure Limitation (SDL) model for protection of tabular data. Numerical results on a test example show that this algorithm is a viable option to the existing methods for solving continuous CTA problems. We also apply the algorithm to the set of randomly generated monotone LCPs showing that the initial implementation performs well on these instances of LCPs. However, this limited numerical testing is done for illustration purposes; an extensive numerical study is necessary to draw more definite conclusions on the behavior of the algorithm. © (2025), (International Academic Press).

Contribution of limited molecular testing to low ehrlichiosis diagnosis in high incidence area, North Carolina, USA
Siegler A , Ursery L , Giandomenico DA , Miller MB , Salzer JS , Barbarin AM , Williams C , Boyce RM . Emerg Infect Dis 2025 31 (2) 281-287 ![]() ![]() Indirect immunofluorescence antibody assays have been the primary method for laboratory diagnosis of ehrlichiosis. Detection of Ehrlichia spp. DNA by using PCR is now widely available through commercial laboratories. To prepare for Ehrlichia spp. PCR introduction, we assessed ehrlichiosis testing practices, quantified the proportion of samples eligible for PCR testing, and estimated the potential effect of implementing PCR at the University of North Carolina health system in North Carolina, USA, which is in an area with a high-incidence of ehrlichiosis. We found <1% of patient samples underwent PCR testing, even though rates of serodiagnostic algorithm completion (testing of acute and convalescent samples) were low (18.4%). Our findings show a need to educate providers on diagnostic and treatment guidelines for ehrlichiosis and raise awareness of the availability and advantage of PCR testing. |
Health preferences in transition: Differences from pandemic to post-pandemic in valuation of COVID-19 and RSV illness in children and adults
Mercon KR , Rose AM , Cadham CJ , Gebremariam A , Pike J , Wittenberg E , Prosser LA . Children (Basel) 2025 12 (2) ![]() Objective: This study aimed to measure changes in preferences regarding health-related quality of life associated with COVID-19 and RSV illness in children and adults from 2021 (during the COVID-19 pandemic) to 2023 (post-pandemic). Methods: A stated-preference survey elicited time trade-off (TTO) values from US adults in spring 2021 (n = 1014) and summer 2023 (n = 1186). Respondents were asked to indicate how much time they would hypothetically be willing to trade from the end of their life to avoid the effects of varying severities of COVID-19 and RSV illness for: (1) children; (2) parents of an ill child (family spillover); and (3) adults. Attitudes relating to COVID-19 vaccination and data on experience with COVID-19 or RSV illness were also collected. The primary outcome measure was the loss in quality-adjusted life years (QALYs). Changes in preferences over the time period from 2021 to 2023 were evaluated using regression analysis. Results: QALY losses increased with disease severity and were highest for Long COVID. Across all COVID-19 and RSV health states, QALY losses associated with child health states were higher than family spillover or adult health states. In the regression analysis, QALY losses reported in the 2023 survey were significantly lower than 2021 QALY losses for COVID-19, but not RSV. Conclusions: Preferences may change over time in a pandemic context and therefore, economic analyses of pandemic interventions should consider the timeframe of health preference data collection to determine whether they are suitable to include in an economic evaluation. Even with the impacts on health-related quality of life attenuated over time, childhood illnesses still had a measurable impact on caregivers' quality of life. |
The five-year impact of state and community program efforts to increase opportunities for healthy eating and active living, 2018 to 2023
Pejavara A , Kahin S , O'Toole T , Petersen R . Health Promot Pract 2025 15248399251319341 ![]() The burden of obesity and other chronic diseases negatively affects the nation's health, businesses, economy, and military readiness. From 2018 to 2023, the Centers for Disease Control and Prevention's Division of Nutrition, Physical Activity, and Obesity (DNPAO) awarded funding to 71 recipients to advance evidence-based strategies to increase opportunities for healthy eating, physical activity, breastfeeding, and tobacco-free living. Recipients consisted of states, universities, and communities funded through the following three cooperative agreements: State Physical Activity and Nutrition (SPAN), Racial and Ethnic Approaches to Community Health (REACH), and the High Obesity Program (HOP). Recipients tailored efforts to their state or local contexts by using community engagement methods, needs assessments, and coalitions to accomplish their work. DNPAO transparently developed an evaluation approach that was feasible for recipients. DNPAO annually collected and validated recipient self-reported data using a two-way cloud-based platform to increase the visibility around data sharing and to ensure real-time communication. SPAN, REACH, and HOP recipients made considerable impact in funded states and communities. For example, more than 28 million people have increased access to places to be physically active, and more than 9 million people have increased access to places with healthy nutrition standards. Recipients also leveraged additional resources from a source other than the granting organization totaling almost US$400 million during the five-year cooperative agreement period. This article documents the combined five-year impact of three public health programs funded by one CDC Division and illustrates the rigorous methods used to evaluate impact. |
Emission-assisted maintenance for advanced diesel engines and exhaust aftertreatment systems in underground mining
Bugarski AD . Min Metall Explor 2025 42 (1) 61-81 ![]() Maintaining the particulate emissions from contemporary diesel engines equipped with diesel particulate filter (DPF) systems at targeted levels and assuring the effectiveness of DPF systems retrofitted to traditional diesel engines are critical to the efforts of underground mining operations to reduce exposures of miners to diesel particulate matter. The methodologies and instrumentation currently used to support the emission-assisted maintenance (EAM) programs for previous generations of diesel engines are in need of improvement to allow for monitoring low concentrations of complex aerosols emitted by the advanced diesel engines. The results showed that of the test conditions currently used in EAM programs, the torque converter stall and hydraulic stall are the most suitable for assessing the effectiveness of the DPF-based advanced aftertreatment systems. The low idle and high idle test conditions, frequently used in EAM programs for traditional engines, did not produce reliable and reproducible data. The solid particle number (SPN) concentrations proved to be more suitable than total particulate number concentrations as a metric for EAM monitoring of diesel aerosols emitted by advanced diesel engines. Both of the evaluated direct reading instruments, TSI 3795-HC and Pegasor Mi3, provided comparably accurate results of assessments of the SPN concentrations in the targeted range of concentrations between 2×10^3 and 3×10^6 #/cm3. Those proved to be viable EAM tools for determination of the efficiencies and performance degradation of the DPF system. The findings of this study should provide the underground mining industry with valuable information needed to enhance their EAM programs. |
Advanced diesel powertrains for underground mining mobile equipment
Bugarski AD , Ritter DA . Min Metall Explor 2025 ![]() Strategies based on the repowering existing and powering new mobile equipment with contemporary diesel engines with substantially lower tailpipe and crankcase emissions are expected to play an important role in the efforts to curtail exposures of underground miners to criteria diesel pollutants. Laboratory characterization of tailpipe emissions for three “clean” engines that meet U.S. Environmental Protection Agency (EPA) Tier 4 final emissions standards were used to assess the viability and effectiveness of those strategies. The evaluated engines were representative of those that achieve the emission standards through implementation of various in-cylinder emissions control strategies, use of crankcase filtration, and use of three types of exhaust aftertreatment systems: (1) diesel oxidation catalytic converter (DOC), (2) combination of DOC and the full-flow wall flow monolith diesel particulate filter (DPF), or (3) combination of DOC, diesel exhaust fluid (DEF)-based selective catalytic reduction (SCR) system, and ammonia slip catalyst (ASC). The study showed that the highest reductions in concentrations of diesel aerosols in underground workings, in terms of both mass and number, could be achieved if the engines, preferably in all power classes, are fitted with viable DPF systems. The use of U.S. EPA Tier 4 final engines equipped with DOC and DOC/SCR/ASC systems could help operators to considerably reduce mass, but not number concentrations of aerosols. The emissions of two of the evaluated engines, one equipped with DOC and the other equipped with DOC/DPF systems, were characterized by substantial secondary NOâ‚‚ emissions that would limit the viability of those engines for underground mining applications. The catalyst formulations used in the exhaust aftertreatment systems of the diesel engines marketed to the underground mining industry need to be formulated to minimize the potential for generation of secondary NOâ‚‚ emissions. Engines fitted with viable SCR/ASC systems present a low-NOâ‚‚ alternative. All three of the evaluated advanced engines were found to have low CO output. Due to nuances associated with the use of diesel-powered mobile equipment in underground mines, the selection and potentially optimization of advanced engines for underground mining applications deserves special consideration. © This is a U.S. Government work and not under copyright protection in the US; foreign copyright protection may apply 2025. |
Fall safety in steel construction: a research study
McKenzie EA Jr , Bobick TG , Hause MG . Prof Saf 2025 70 (2) 20-29 ![]() Key takeaways: Workers at elevation can be exposed to falls to a lower level when working. A personal fall arrest system is designed to stop workers from experiencing free fall, but even after the system engages, a worker will continue to fall. A NIOSH study compared the end effects of using a proper and improper personal fall arrest lanyard in a 12-ft free fall foot-level tie off. A 12-ft free fall personal fall arrest lanyard should always be used for free fall distances greater than 6 ft. A 6-ft free fall personal fall arrest lanyard should never be used at foot-level tie off. The personal energy absorber reached its maximum effectiveness during pullout and stopped extending. When this occurred, an excessive force spike was measured before the fall was fully arrested. Energy is absorbed in the mannequin's harness, as well as the personal fall arrest lanyard during a fall arrest, resulting in a shorter pullout length of the personal fall arrest lanyard as compared to a drop weight. |
A preliminary quantitative risk assessment for inhalation exposure to glutaraldehyde
Pandalai SP , Dankovic DA . J Appl Toxicol 2025 ![]() Glutaraldehyde (Chemical Abstracts Service [CAS] registry number 111-30-8) has various occupational uses and is associated with adverse health effects including respiratory tract irritation, asthma, and chronic obstructive pulmonary disease. A quantitative risk assessment was conducted to evaluate the likelihood of adverse health effects associated with differing levels of occupational inhalation exposure to glutaraldehyde. Dose-response models were fit to data from a 2-year glutaraldehyde inhalation exposure bioassay conducted by the National Toxicology Program. The benchmark concentration lower bound values of 32 and 44 parts per billion (ppb) were based on bioassay data for female rats and mice that developed squamous epithelium inflammation and respiratory epithelium squamous metaplasia, respectively. These values were used as a point of departure to determine exposure levels relevant to the occupational setting. Extrapolation from rodents to humans assumed a 40-h workweek and an 8-fold uncertainty factor to account for interspecies and interindividual variability. Adjusted benchmark lower bound concentrations of 3 and 4.1 ppb were calculated for inhalation exposure to glutaraldehyde using the endpoints observed in rat and mouse models. Due to the extrapolation parameters used in deriving this result, these findings have applicability for exposure to glutaraldehyde in the occupational setting. |
Entomological profiles of households in plasmodium falciparum case foci and comparison areas in Grand'Anse, Haiti
Joseph V , Sutcliffe A , Leite L , Czeher C , Druetz T , Rogier E , Eisele TP , Lemoine JF , Chang M , Impoinvil D , Ashton RA . Am J Trop Med Hyg 2025 ![]() Hispaniola, which is shared by Haiti and the Dominican Republic, remains the last island in the Caribbean that is still endemic for malaria, with Haiti bearing the highest caseload. Few studies have examined the ecology of malaria vectors in Haiti. Five species of Anopheles have been described on the island, but the exophilic Anopheles albimanus (An. albimanus) is considered the primary vector of malaria in Haiti. Households recruited for a case-control study profiling risk factors for symptomatic Plasmodium falciparum (P. falciparum) infections were approached to participate in an entomological study. The goal was to determine the bionomics of anopheline mosquitoes around the 32 participating households across varying malaria transmission settings. We assessed the characteristics of the Anopheles population using ultraviolet-light traps and larval surveys. Anopheles albimanus was the most abundant mosquito species identified in the Grand'Anse. Its abundance was higher in outdoor traps than in indoor traps and in areas with relatively high positivity based on rapid diagnostic test results. A greater proportion of blood-fed mosquitoes were found in higher transmission areas. Anopheles albimanus samples were found to be infected with both P. falciparum and Plasmodium vivax sporozoites. As Haiti aims for the elimination of malaria, disrupting localized residual malaria transmission will increasingly rely on focal vector control strategies. |
Embedding physical activity training in state child care systems: An evaluation of the physical activity learning sessions
Duchette R , Payes R , Botsko C , Dooyema C , West M , Dahl K . Health Promot Pract 2025 15248399251320977 ![]() Child care programs can be one setting for promoting physical activity (PA). To support technical assistance providers in promoting PA best practices, Nemours Children's Health with the Centers for Disease Control and Prevention developed a set of trainings known as Physical Activity Learning Sessions (PALS). PALS centers on PA best practices, and state partners are encouraged to embed the program into early care and education (ECE) systems, such as training and TA networks. From 2019 to 2023, 22 states and 802 individuals completed a PALS train-the-trainer (TTT) course. This brief highlights findings from the 2022-2023 PALS evaluation, examining the extent to which PALS provided ECE trainers with effective training materials, affected trainer confidence in providing PA trainings to ECE providers, and was integrated into state systems. The PALS evaluation included a mixed-methods design consisting of pre-, post-, and 6-month post-TTT surveys of trainers. Among trainers, 87% of 125 respondents said they were confident training ECE providers on PA practices after completing the PALS TTT. Nearly 67% of participants planned to deliver a PALS training to ECE providers within 6 months of completing the TTT. Surveys from 16 of 18 PALS state leads suggested PALS has been embedded in state ECE systems. PALS counts for training credit of some type in 10 states, including licensing, provider credentials, and Quality Rating and Improvement Systems. Additional evaluation efforts could determine the impact of PALS on PA practices and policies among ECE providers and programs. |

Aids 2025 39 (4) 434-447 ![]() OBJECTIVE: Using an innovative data sharing model, we assessed the impacts of the COVID-19 pandemic on the health of people who inject drugs (PWID). DESIGN: The PWID Data Collaborative was established in 2021 to promote data sharing across PWID studies in North America. Contributing studies submitted aggregate data on 23 standardized indicators during four time periods: prepandemic (March 2019 to February 2020), early-pandemic (March 2020 to February 2021), mid-pandemic (March 2021 to February 2022), and late pandemic (March 2022 to February 2023). METHODS: We present study-specific and meta-analyzed estimates for the percentage of PWID who took medications for opioid use disorder, received substance use treatment, shared syringes or injection equipment, had a mental health condition, had been incarcerated, or had experienced houselessness. To examine change over time across indicators, we fit a random effects meta-regression model to prevalence estimates using time as a moderator. RESULTS: Thirteen studies contributed estimates to the Data Collaborative on these indicators, representing 6213 PWID interviews. We observed minimal change across prevalence of the six indicators between the prepandemic (March 2019 to February 2020) and three subsequent time periods, overall or within individual studies. Considerable heterogeneity was observed across study-specific and time-specific estimates. CONCLUSION: Limited pandemic-related change observed in indicators of PWID health is likely a result of policy and supportive service-related changes and may also reflect resilience among service providers and PWID themselves. The Data Collaborative is an unprecedented data sharing model with potential to greatly improve the quality and timeliness of data on the health of PWID. |
Characterising people who inject drugs, and association with HIV infection: A situation analysis in Kampala City, Uganda
Mudiope P , Mathers B , Nangendo J , Mutyaba S , Mutamba BB , Alamo S , Nanyenya N , Makumbi F , Laker-Oketta M , Wanyenze R . PLOS Glob Public Health 2025 5 (2) e0003370 ![]() Uganda implements interventions for injection drug use, but significant barriers hinder efforts to effectively reach and support persons who inject drugs (PWID). We describe characteristics of PWID, and associated risk behaviour, to inform the designing of programmes that are tailored to clients' needs and preferences. A cross-sectional survey (August 23rd to December 5th, 2023) in Kampala interviewed 354 PWID (≥18-years) at selected venues(bars,lodges, street corners and ghetto). Peer eductors and counsellors administered a structured questionnaire covering socio-demographics, drug use, sexual risk, and medical history. HIV serostatus was determined by self-report or testing for consenting participants without history of recent testing Binary logistic regression was used to establish the relationship between HIV infection and risky drug- and sexual behaviour of PWID. Participants were predominantly Ugandan (95.2%), male (73.2%), unmarried (55.9%), unemployed (81.8%), with higher levels of education and varying ages. Mental disorders were prevalent, with 48.7% reporting at least one underlying condition, including depression (30.8%) and anxiety (9.6%). Physical health issues included fever (32.9%), cough (32.5%), malaria (22%), and sexually transmitted infections (15%). Over 82.6% were introduced to drugs by close acquaintances. HIV prevalence among participants was 3.7%, higher in females (8.4%) and non-Ugandans (16.7%). Being female and experiencing difficulty accessing sterile injection materials were associated with HIV-positive status. Our study provides valuable insight into the socio-demographic, mental, physical health, and HIV risk behaviour of PWID in Kampala, Uganda. The findings indicate significant vulnerabilities to injecting drug use, mental disorders, and high-risk behaviors that predispose this population to HIV infection. Despite a low HIV prevalence in this population compared to previous estimates, the interplay between drug use, risky injecting practices, and sexual behaviour suggests an urgent need for targeted interventions to address these intertwined challenges. |
Bayou hantavirus cardiopulmonary syndrome, Louisiana, USA, 2022-2023
Ortega E , Simonson S , Shedroff E , Whitmer S , Whitesell A , Choi MJ , Shoemaker T , Montgomery JM , Klena JD , Hennig J , Sokol T . Emerg Infect Dis 2025 31 (2) 401-403 ![]() ![]() During 2020-2023, we sequenced Bayou virus from 2 patients in Louisiana, USA, with hantavirus cardiopulmonary syndrome. Direct virus sequencing demonstrated an inferred evolutionary relationship to previous cases. Our findings demonstrate that separate virus spillovers cause isolated cases and probable wide distribution of Bayou hantavirus in rodents across Louisiana. |
Clinical, prognostic, and longitudinal functional and neuropsychological features of West Nile Virus neuroinvasive disease in the United States: A systematic review and meta-analysis
Roberts JA , Kim CY , Hwang SA , Hassan A , Covington E , Heydari K , Lyerly M , Sejvar JJ , Hasbun R , Prasad M , Thakur KT . Ann Neurol 2025 ![]() OBJECTIVE: West Nile virus (WNV) is the most common cause of arboviral disease in the United States. Approximately 1% of infections involve the nervous system, most commonly resulting in West Nile encephalitis (WNE), West Nile meningitis (WNM), or acute flaccid paralysis (AFP). METHODS: In this systematic review, we characterized comprehensively the diagnostic and clinical features of WNV neuroinvasive disease (WNND) in the United States, as well as the evidence regarding prognostic factors and long-term outcomes of WNND. RESULTS: We identified 47 relevant studies reporting data on acute or longitudinal features of WNND. Across studies, the most common presenting symptoms were fever (88%), nausea/vomiting (58%), and fatigue (50%) coupled neurologically with headache (50%), altered mental status (39%), and focal weakness (32%). Pooled mortality was 9.2%, and 42.1% of reported cases required intensive care unit (ICU) admission. In meta-analyses, chronic kidney disease (odds ratio [OR] = 5.99, 95% confidence interval [CI] = 2.71-13.23), diabetes mellitus (OR = 2.43, 95% CI = 1.54-3.84), and hypertension (OR = 4.01, 95% CI = 2.39-6.72) were associated with an increased risk of mortality. Multidomain neurocognitive impairment was reported in several studies at post-hospitalization follow-up, although with marked heterogeneity between study methodology. Subjective neurocognitive impairment, most notably fatigue (37-75%), memory concerns (11-57%), concentration deficits (17-48%), and depression (17-38%), were also common at post-hospitalization follow-up. INTERPRETATION: These findings underscore the significant mortality and morbidity of WNND in the acute and long-term setting. Our findings may additionally provide utility for risk stratification of hospitalized patients with WNND and suggest the need for further evaluation of novel therapeutics to prevent substantial disease-associated acute and long-term disability.

Dengue outbreak and response - Puerto Rico, 2024
Ware-Gilmore F , Rodriguez DM , Ryff Mph K , Torres JM , Velez MP , Torres-Toro CT , Santiago GA , Rivera A , Madewell ZJ , Maldonado Y , Cardona-Gerena I , Brown GC , Adams LE , Paz-Bailey G , Marzán-Rodriguez M . MMWR Morb Mortal Wkly Rep 2025 74 (5) 54-60 ![]() Dengue, a mosquitoborne viral infection, is a public health threat in Puerto Rico, where multiple dengue virus (DENV) serotypes circulate. Dengue causes an acute febrile illness that can progress to severe disease or death. The last outbreak declared by the Puerto Rico Department of Health occurred during 2013. In January 2024, the number of dengue cases in Puerto Rico surpassed the epidemic threshold and remained elevated, prompting the Puerto Rico Department of Health to declare a public health emergency in March 2024. In collaboration with CDC, a dengue outbreak response was initiated to monitor the outbreak and implement vector-control measures alongside public health campaigns to raise awareness about increasing dengue case numbers and strategies to prevent mosquito bites. During 2024, a total of 6,291 confirmed dengue cases were reported; the highest numbers of cases were reported in the municipalities of San Juan (1,200; 17.3%), Carolina (354; 5.1%), and Rincón (252; 3.6%). DENV serotype 3 predominated, accounting for 59.2% of cases with known serotype. Approximately one half of ill patients (52.3%) required hospitalization, with the highest percentages of hospitalizations (33.9%) and severe dengue cases (28.4%) occurring among persons aged 10-19 years. Overall, severe dengue was identified in 4.2% of cases, with 11 reported fatalities (0.2%). Transmission remains elevated in multiple regions, underscoring the need for tailored public health measures, including vaccination among eligible populations, vector management, community outreach, and provider education to facilitate improved outcomes. To reduce the risk for mosquito bites, residents of and visitors to Puerto Rico should consider using repellents, wearing protective clothing, and staying in places with door and window screens. |
