BMC Infect Dis 2024 24 (1) 1179 BACKGROUND: Streptococcus pneumoniae (S. pneumoniae), Haemophilus influenzae (H. influenzae), and Neisseria meningitidis (N. meningitidis) are leading causes of childhood bacterial meningitis and preventable by vaccines. The aim of this hospital-based sentinel surveillance is to describe the epidemiological characteristics of pneumococcal meningitis, including disease burden, and to provide baseline data on pneumococcal serotype distribution to support decision making for pneumococcal conjugate vaccine (PCV) introduction in Vietnam. METHODS: Surveillance for probable bacterial meningitis in children 1-59 months of age is conducted in three tertiary level pediatric hospitals: one in Hanoi and two in Ho Chi Minh City. Cerebrospinal fluid (CSF) specimens were collected via lumbar puncture from children with suspected meningitis. Specimens were transferred immediately to the laboratory department of the respective hospital for cytology, biochemistry, and microbiology testing, including culture. PCR testing was conducted on CSF specimens for bacterial detection (S. pneumoniae, H. influenzae, and N. meningitidis) and pneumococcal serotyping. RESULTS: During 2015-2018, a total of 1,803 children with probable bacterial meningitis were detected; 1,780 had CSF specimens available for testing. Of 245 laboratory-confirmed positive cases, the majority were caused by S. pneumoniae (229,93.5%). Of those with S. pneumoniae detected, over 70% were caused by serotypes included in currently available PCV products; serotypes 6 A/6B (27.1%), 14 (19.7%), and 23 F (16.2%) were the most common serotypes. Children with laboratory-confirmed pneumococcal meningitis were more likely to live in Hanoi (p < 0.0001) and children 12-23 months of age were at greater odds (OR = 1.65, 95% CI: 1.11, 2.43; p = 0.006) of having confirmed pneumococcal meningitis compared to children < 12 months of age when compared to those without laboratory-confirmed bacterial meningitis. Additionally, children with confirmed pneumococcal meningitis were more likely to exhibit signs and symptoms consistent with clinical meningitis compared to negative laboratory-confirmed meningitis cases (p < 0.0001) and had a greater odds of death (OR = 6.18, 95% CI: 2.98, 12.86; p < 0.0001). CONCLUSIONS: Pneumococcal meningitis contributes to a large burden of bacterial meningitis in Vietnamese children. A large proportion are caused by serotypes covered by PCVs currently available. Introduction of PCV into the routine immunization program could reduce the burden of pneumococcal meningitis in Viet Nam. |
A qualitative assessment of changes in occupational exposures among healthcare facility workers
Gimeno Ruiz de Porras D , Patel J , Conway S , Pompeii L , Mitchell LE , Carson A , Whitehead LW , Han I , Zock JP , Henneberger PK , Patel R , De Los Reyes J , Delclos GL . Workplace Health Saf 2024 21650799241284085 Adult-onset asthma, notably prevalent among healthcare professionals, especially nurses, is often attributed to occupational factors such as exposure to cleaning agents. Studies consistently underscore the substantial role of such exposure in work-related asthma among hospital staff. We aimed to (a) identify and characterize current practices in cleaning and aerosolized medication administration; (b) assess changes in practices since a similar 2003 study of Texas healthcare workers; and (c) identify factors contributing to diverse exposures within healthcare job categories. We conducted focus groups with 38 participants in 6 healthcare settings, analyzing current practices, changes since 2003, and factors contributing to exposure diversity. We used a three-step approach for data analysis, including sociodemographic characterization, a scissor-and-sort technique for exposure description, and qualitative content analysis. Participants were primarily healthcare providers (76%) and housekeepers/cleaners (11%) who reported exposure to aerosolized medications, cleaning products, adhesives, and solvents. Participants reported transitioning from cleaning practices to new formulas with reduced odors and shifting from spray cleansers to wipes. Personal protective equipment (PPE) used during cleaning tasks varied, with training differing among job categories. Aerosolized medication administration varied among facilities, with reported medication types and protocol changes over time. The results emphasized the significance of maintaining uniform protection, disseminating knowledge, and consistently adhering to PPE protocols in the healthcare environment. Addressing the identified gaps in comprehension and potential sources of exposure variability requires additional focus on occupational health and safety initiatives. |

Health Security 2024 In the early years of the COVID-19 pandemic, unprecedented public health measures were designed and implemented to mitigate the spread of SARS-CoV-2. On January 26, 2021, US Centers for Disease Control and Prevention (CDC) staff began daily audits of documents of arriving passengers at 18 US international ports of entry to ensure documentation of either a negative predeparture antigen or nucleic acid amplification test result for SARS-CoV-2 or recent recovery from COVID-19. This case study briefly describes the results of those audits. The CDC found a very low rate of issues overall. Of the 483,251 passengers selected for audit, 2,142 (0.44%) had issues with their COVID-19 test documentation and 1,182 (0.24%) provided documentation of recovery from COVID-19 rather than a negative test result. The low rate of issues noted during traveler audits indicated airlines were largely compliant with the order. However, the burden of SARS-CoV-2 infections within the United States was high during much of this period, which suggests that implementing a predeparture testing requirement earlier in the pandemic might have had more impact on spread. Digital solutions could reduce the burden of similar interventions in the future on airlines, public health authorities, and other partners. © Mary Ann Liebert, Inc. |
Asking for verbal sexual consent and experiences of sexual violence and sexual behaviors among high school students - Youth Risk Behavior Survey, United States, 2023
Szucs LE , Pampati S , Jozkowski KN , DeGue S , Rasberry CN , Brittain AW , Copen C , Zimbelman L , Leonard S , Young E , Trujillo L . MMWR Suppl 2024 73 (4) 59-68 Adolescents' sexual consent behaviors are critical for developing healthy sexual relationships and preventing experiences of sexual violence. This report uses 2023 Youth Risk Behavior Survey data to describe prevalence of asking for sexual consent verbally at last sexual contact among U.S. high school students. Differences in prevalence of asking for sexual consent verbally by sex, age, race and ethnicity, sexual identity, sex of sexual contacts, and gender identity were examined. Differences in asking for sexual consent verbally also were examined by experiences of sexual violence and sexual behaviors. Sex-stratified logistic regression analyses were performed to determine the association between asking for sexual consent verbally with experiences of sexual violence and sexual behaviors. In addition, data were analyzed using adjusted logistic regression models controlling for age, race and ethnicity, and sexual identity. Among high school students who reported ever having sexual contact, 79.8% reported asking for sexual consent verbally at last sexual contact. A lower percentage of female students (74.5%) reported asking for sexual consent verbally than male students (84.6%). In adjusted sex-stratified analyses, female students who asked for sexual consent verbally had higher prevalence of ever having had sexual intercourse. Male students who asked for sexual consent verbally had higher prevalence of ever having had sexual intercourse and being currently sexually active. Female and male students who asked for sexual consent verbally had higher prevalence of having first sexual intercourse before age 13 and using condoms. In addition, female students who asked for sexual consent verbally during last sexual intercourse had lower prevalence of using alcohol or drugs at last sexual intercourse. Public health researchers and practitioners, health care providers, schools, and youth-serving organizations can use these findings to better understand high school students' verbal sexual consent, improve complex measurement of consent-seeking behaviors, and guide multicomponent sexual health and violence prevention efforts across various settings. |

Racial disparities and achievement of the Low Lupus Disease Activity State (LLDAS): A CARRA Registry Study
Soulsby WD , Olveda R , He J , Berbert L , Weller E , Barbour KE , Greenlund KJ , Schanberg LE , von Scheven E , Hersh A , Son MBF , Chang J , Knight A . Arthritis Care Res (Hoboken) 2024 OBJECTIVE: Differential disease control may contribute to racial disparities in outcomes of childhood-onset systemic lupus erythematosus (cSLE). We evaluated associations of race and individual- or neighborhood-level social determinants of health (SDoH) with achievement of low lupus disease activity state (LLDAS), a clinically relevant treatment target. METHODS: In this cSLE cohort study using the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry, the primary exposure was self-reported race and/or ethnicity and collected SDoH included insurance status and area deprivation index (ADI). Outcomes included LLDAS, disease activity, and time-averaged prednisone exposure. Associations between race and/or ethnicity, SDoH, and disease activity were estimated with multivariable regression models, adjusting for disease-related and demographic factors. RESULTS: Among 540 children with cSLE, 27% identified as Black, 25% White, 23% Latino/a, 11% Asian, 9% more than one race, and 5% Other. More Black children (41%) lived in neighborhoods of highest ADI compared to White children (16%). Black race was associated with lower LLDAS achievement (adjusted OR 0.56, 95% CI: 0.38-0.82) and higher disease activity (adjusted β: 0.94, 95% CI: 0.11, 1.78). Highest ADI was not associated with lower LLDAS achievement upon adjustment for renal disease and insurance. However, renal disease was found to be a significant mediator (p=0.04) of the association between ADI and prednisone exposure. CONCLUSIONS: Children with cSLE identifying as Black are less likely to achieve LLDAS and have higher disease activity. Living in areas of higher ADI may relate to renal disease and subsequent prednisone exposure. Strategies to address root causes will be important to design interventions mitigating cSLE racial disparities. |
SARS-CoV-2 infection and other communicable diseases identified among evacuees from Afghanistan arriving in Virginia and Pennsylvania, August to September 2021
Gearhart SL , Preston LE , Christensen DL , Kinzer MH , Ohlsen EC , Kim C , Palo MR , Rothney E , Klevos AD , Pieracci EG , Hausman LB , Rey A , Sockwell D , Lawman H , Alvarado-Ramy F , Brown C , Gertz AM . Public Health Rep 2024 333549241277375 In 2021, the US government undertook Operation Allies Welcome, in which evacuees from Afghanistan arrived at 2 US ports of entry in Virginia and Pennsylvania. Because of the rapid evacuation process, the US government granted evacuees an exemption to a Centers for Disease Control and Prevention (CDC) requirement in place at that time-namely, that air passengers present a negative SARS-CoV-2 viral test result or documentation of recovery from COVID-19 before they boarded international flights bound for the United States. This study describes cases of SARS-CoV-2 infection detected among 65 068 evacuees who arrived at the 2 ports of entry in August and September 2021. Because evacuees were a population at increased risk for infection with diseases of public health concern, CDC staff helped coordinate on-site and on-arrival testing, visually observed evacuees for signs and symptoms of communicable disease, and referred evacuees for further evaluation and treatment as needed. CDC staff used antigen or nucleic acid amplification tests at the ports of entry to evaluate evacuees aged ≥2 years without documentation of recent SARS-CoV-2 infection. CDC staff isolated evacuees with confirmed SARS-CoV-2 infection and quarantined their close contacts, consistent with CDC guidance at the time, before evacuees rejoined the repatriation process. Of 65 068 evacuees, 214 (0.3%) were confirmed as having SARS-CoV-2 infection after port-of-entry testing. Cases of measles, varicella, pertussis, tuberculosis, hepatitis A, malaria, leishmaniasis, and diarrheal illness were also identified. Although the percentage of SARS-CoV-2 infection was low in this evacuated population, communicable disease detection at US ports of entry, along with vaccination efforts, was an important part of a multilayered approach to mitigate the transmission of disease in congregate housing facilities and into US communities. |
Associations between acute COVID-19 symptom profiles and long COVID prevalence: Population-based cross-sectional study
Hirschtick JL , Slocum E , Xie Y , Power LE , Elliott MR , Orellana RC , Fleischer NL . JMIR Public Health Surveill 2024 10 e55697 BACKGROUND: Growing evidence suggests that severe acute COVID-19 illness increases the risk of long COVID (also known as post-COVID-19 condition). However, few studies have examined associations between acute symptoms and long COVID onset. OBJECTIVE: This study aimed to examine associations between acute COVID-19 symptom profiles and long COVID prevalence using a population-based sample. METHODS: We used a dual mode (phone and web-based) population-based probability survey of adults with polymerase chain reaction-confirmed SARS-CoV-2 between June 2020 and May 2022 in the Michigan Disease Surveillance System to examine (1) how acute COVID-19 symptoms cluster together using latent class analysis, (2) sociodemographic and clinical predictors of symptom clusters using multinomial logistic regression accounting for classification uncertainties, and (3) associations between symptom clusters and long COVID prevalence using modified Poisson regression. RESULTS: In our sample (n=4169), 15.9% (n=693) had long COVID, defined as new or worsening symptoms at least 90 days post SARS-CoV-2 infection. We identified 6 acute COVID-19 symptom clusters resulting from the latent class analysis, with flu-like symptoms (24.7%) and fever (23.6%) being the most prevalent in our sample, followed by nasal congestion (16.4%), multi-symptomatic (14.5%), predominance of fatigue (10.8%), and predominance of shortness of breath (10%) clusters. Long COVID prevalence was highest in the multi-symptomatic (39.7%) and predominance of shortness of breath (22.4%) clusters, followed by the flu-like symptom (15.8%), predominance of fatigue (14.5%), fever (6.4%), and nasal congestion (5.6%) clusters. After adjustment, females (vs males) had greater odds of membership in the multi-symptomatic, flu-like symptom, and predominance of fatigue clusters, while adults who were Hispanic or another race or ethnicity (vs non-Hispanic White) had greater odds of membership in the multi-symptomatic cluster. Compared with the nasal congestion cluster, the multi-symptomatic cluster had the highest prevalence of long COVID (adjusted prevalence ratio [aPR] 6.1, 95% CI 4.3-8.7), followed by the predominance of shortness of breath (aPR 3.7, 95% CI 2.5-5.5), flu-like symptom (aPR 2.8, 95% CI 1.9-4.0), and predominance of fatigue (aPR 2.2, 95% CI 1.5-3.3) clusters. CONCLUSIONS: Researchers and clinicians should consider acute COVID-19 symptom profiles when evaluating subsequent risk of long COVID, including potential mechanistic pathways in a research context, and proactively screen high-risk patients during the provision of clinical care. |
Continuum of health equity practice and science: conceptualising health equity research and practice for injury prevention
Scheuer H , Wulz AR , Carmichael AE , Welder LE . Inj Prev 2024 BACKGROUND: Integrating and advancing health equity are a core tenant of the Centers for Disease Control and Prevention's mission. Comprehensive frameworks that clearly conceptualise equity are needed to prioritise and inform the advancement of health equity within public health. METHODS: To help meet this need, the investigative team developed The Continuum of Health Equity Practice & Science (The Continuum). The Continuum was developed in two phases: (1) an initial survey distributed to internal CDC Division of Injury Prevention investigators, and (2) a review of public health frameworks and the current health equity evidence base. RESULTS: The Continuum is a framework that includes seven key components of health equity and ultimately aims to guide public health practice and research towards the advancement of health equity. To illustrate its usefulness, we provide an example using adolescent suicide for each component of The Continuum and demonstrate how this may inform efforts to advance health equity. CONCLUSION: With a specific focus on conceptualising health equity and addressing systemic inequities, The Continuum may be used to inform efforts to advance equity in injury prevention and beyond. |
Differences in drug poisonings among those who identify as transgender compared to cisgender: An analysis of the Toxicology Investigators Consortium (ToxIC) Core Registry, United States 2017-2021
Magnusson K , Glidden E , Mustaquim D , Welder LE , Stokes EK , Beauchamp GA , Greenberg MR , Aldy K , Mazzaccaro RJ , Careyva BA , Sabino JN , Fikse DJ , McLain K , Amaducci AM . Clin Ther 2024 PURPOSE: In this manuscript, the abbreviation TG is defined as persons who identify as transgender, GNC is defined as persons who identify as gender nonconforming, and CG is defined as persons who identify as cisgender. TG and GNC (e.g., nonbinary), are those whose gender identity and sex assigned at birth do not align, as opposed to CG. This study describes drug poisonings among TG, GNC, and CG captured in the Toxicology Investigators Consortium (ToxIC) Core Registry during 2017-2021. METHODS: Authors conducted a secondary data analysis of medical toxicology physician consultations involving intentional exposures (i.e., use with the knowledge of the exposed person) within the ToxIC Core Registry from 2017 through 2021. Demographic characteristics, exposure intent, and reported drug classes are reported by gender identity and sex assigned at birth. FINDINGS: From a total of 15,800 medical toxicology consultations, 213 (1.3%) involved both TG (n = 187, 1.2%) and GNC (n = 26, 0.2%), and 15,587 (98.7%) involved CG. Among TG, 128 (68.8%) were transgender men, 58 (31.2%) transgender women. Sixty-two percent of TG/GNC (n = 132) and 34.8% of CG (n = 5,428) were aged ≤18 years. Reported intent for exposure (i.e., self-harm and misuse/harmful use) differed proportionally across both sexes assigned at birth and gender identity among transgender men and cisgender men. IMPLICATIONS: In the ToxIC Core Registry, the consultations varied proportionally by age group across TG/GNC and CG, with more than half of TG/GNC aged ≤18 years. The proportion of consultations also varied by intent across TG/GNC and CG. Further research to delineate differences between TG/GNC and CG could increase knowledge in prevention, assessment, and treatment of drug poisonings in this population. |
Trends in contacts made by immigrants to the National Domestic Violence Hotline, before and during the COVID-19 Pandemic
Treves-Kagan S , Le VD , Berra LS , Ray CM , Ruvalcaba Y , Wood L , D'Angelo DV , Vera TM , Estefan LF . Public Health Rep 2024 333549241279101 OBJECTIVES: Immigrants in the United States are more likely than nonimmigrants to experience risk factors for intimate partner violence (IPV) and problems in getting support. The COVID-19 pandemic and recent incidents of xenophobia and anti-immigrant sentiment may have exacerbated exposure to IPV risk factors. We examined immigrant experiences of IPV before and during the COVID-19 pandemic. METHODS: This study identified changes in characteristics of abuse, services used, referrals, and barriers to services among those who contacted the National Domestic Violence Hotline (NDVH) and identified as immigrants, reported immigration status as a concern, needed immigration support, and/or identified immigration status as a barrier to accessing services (N = 49 817). We used joinpoint regressions to examine whether the rate of change differed significantly from 2016-2019 (before the pandemic) to 2019-2021 (during the pandemic). RESULTS: The number of immigrant contacts to NDVH peaked in 2017 (n = 9333) and declined 25% to 6946 in 2021. During 2016-2019, the percentage of contacts reporting the following increased significantly: technology-facilitated violence (+12.7 percentage points), economic/financial abuse (+10.8 percentage points), and involvement of firearms (+4.8 percentage points); during 2019-2021, these trends reversed. The percentage of contacts reporting separation or divorce was relatively flat until 2019 and then increased from 14.6% in 2019 to 19.9% in 2021 (+5.2 percentage points). Housing instability increased during 2017-2020 (+9.3 percentage points), but requests for shelters decreased (-4.5 percentage points). Immigration status and personal finances were commonly reported barriers to services; both decreased during 2016-2019 but then increased during 2019-2021. CONCLUSIONS: This study can inform prevention and response strategies relevant for immigrants experiencing or reporting IPV. |
Cervical cancer incidence in the US-affiliated Pacific Islands
Gopalani SV , Qin J , Baksa J , Thompson TD , Saraiya M , Senkomago V , Pordell P , Jeong Y , Palafox NA , Reichhardt M , Buenconsejo-Lum LE . JAMA Oncol 2024 IMPORTANCE: The World Health Organization has called for eliminating cervical cancer as a public health problem. Accurate and up-to-date estimates of population-based cervical cancer incidence are essential for monitoring progress toward elimination and informing local cancer control strategies, but these estimates are lacking for the US-Affiliated Pacific Islands (USAPI). OBJECTIVE: To calculate age-standardized incidence rates for cervical cancer in the 6 USAPI and compare these rates with rates in the US (50 states and the District of Columbia). DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used population-based data from the Pacific Regional Central Cancer Registry for women aged 20 years or older who were diagnosed with invasive cervical cancer from January 1, 2007, to December 31, 2020. The registry comprises data on all cervical cancers from the USAPI, which include 3 US territories (American Samoa, Commonwealth of the Northern Mariana Islands, and Guam) and 3 freely associated states (Federated States of Micronesia [FSM], Republic of the Marshall Islands [RMI], and Republic of Palau). Data were analyzed from July 10, 2023, to November 28, 2023. MAIN OUTCOMES AND MEASURES: The main outcome was age-standardized cervical cancer incidence rates, stratified by age, stage, and histologic code for the USAPI using population estimates from 3 different sources (US Census Bureau International Database, United Nations Population Division, and Pacific Data Hub). Rate ratios were calculated to compare incidence rates between the USAPI and the US. RESULTS: From 2007 to 2020, 409 cases of cervical cancer were diagnosed in the USAPI (median age at diagnosis, 46.0 years [25th-75th percentile, 39.0-55.0 years]), with an age-standardized incidence rate ranging from 21.7 (95% CI, 19.6-23.9) to 22.1 (95% CI, 20.0-24.4) per 100 000 women, depending on the population estimate. Incidence rates were highest in RMI, ranging from 58.1 (95% CI, 48.0-69.7) to 83.4 (95% CI, 68.3-101.0) per 100 000 women, followed by FSM, ranging from 28.7 (95% CI, 23.4-34.9) to 29.8 (95% CI, 24.3-36.3) per 100 000 women. Compared with the US, incidence rates were highest in RMI (rate ratio, 5.7 [95% CI, 4.7-6.8] to 8.2 [95% CI, 6.7-9.9]) and FSM (rate ratio; 2.8; 95% CI, 2.3-3.4). Of all cases in the USAPI, 213 (68.2%) were diagnosed at a late stage. CONCLUSIONS AND RELEVANCE: In this cross-sectional study, cervical cancer remained a major public health issue in some USAPI, with RMI reporting the highest incidence rates. The findings suggest that improvements in human papillomavirus vaccination and cancer screening coverage through efforts tailored to the unique geographic, sociocultural, economic, and health care landscape of the USAPI may reduce the burden of cervical cancer. |
Fatal meningoencephalitis associated with Ebola virus persistence in two survivors of Ebola virus disease in the Democratic Republic of the Congo: a case report study

Lancet Microbe 2024 100905 BACKGROUND: During the 2018-20 Ebola virus disease outbreak in the Democratic Republic of the Congo, thousands of patients received unprecedented vaccination, monoclonal antibody (mAb) therapy, or both, leading to a large number of survivors. We aimed to report the clinical, virological, viral genomic, and immunological features of two previously vaccinated and mAb-treated survivors of Ebola virus disease in the Democratic Republic of the Congo who developed second episodes of disease months after initial discharge, ultimately complicated by fatal meningoencephalitis associated with viral persistence. METHODS: In this case report study, we describe the presentation, management, and subsequent investigations of two patients who developed recrudescent Ebola virus disease and subsequent fatal meningoencephalitis. We obtained data from epidemiological databases, Ebola treatment units, survivor programme databases, laboratory datasets, and hospital records. Following national protocols established during the 2018-20 outbreak in the Democratic Republic of the Congo, blood, plasma, and cerebrospinal fluid (CSF) samples were collected during the first and second episodes of Ebola virus disease from both individuals and were analysed by molecular (quantitative RT-PCR and next-generation sequencing) and serological (IgG and IgM ELISA and Luminex assays) techniques. FINDINGS: The total time between the end of the first Ebola virus episode and the onset of the second episode was 342 days for patient 1 and 137 days for patient 2. In both patients, Ebola virus RNA was detected in blood and CSF samples during the second episode of disease. Complete genomes from CSF samples from this relapse episode showed phylogenetic relatedness to the genome sequenced from blood samples collected from the initial infection, confirming in-host persistence of Ebola virus. Serological analysis showed an antigen-specific humoral response with typical IgM and IgG kinetics in patient 1, but an absence of an endogenous adaptive immune response in patient 2. INTERPRETATION: We report the first two cases of fatal meningoencephalitis associated with Ebola virus persistence in two survivors of Ebola virus disease who had received vaccination and mAb-based treatment in the Democratic Republic of the Congo. Our findings highlight the importance of long-term monitoring of survivors, including continued clinical, virological, and immunological profiling, as well as the urgent need for novel therapeutic strategies to prevent and mitigate the individual and public health consequences of Ebola virus persistence.

Contact tracing for mpox clade II cases associated with air travel - United States, July 2021-August 2022
Delea KC , Chen TH , Lavilla K , Hercules Y , Gearhart S , Preston LE , Hughes CM , Minhaj FS , Waltenburg MA , Sunshine B , Rao AK , McCollum AM , Adams K , Ocaña M , Akinkugbe O , Brown C , Alvarado-Ramy F . MMWR Morb Mortal Wkly Rep 2024 73 (35) 758-762 Monkeypox virus (MPXV) can spread among humans through direct contact with lesions, scabs, or saliva; via respiratory secretions; and indirectly from fomites; via percutaneous injuries; and by crossing the placenta to the fetus during pregnancy. Since 2022, most patients with mpox in the United States have experienced painful skin lesions, and some have had severe illness. During 2021-2022, CDC initiated aircraft contact investigations after receiving reports of travelers on commercial flights with probable or confirmed mpox during their infectious period. Data were collected 1) during 2021, when two isolated clade II mpox cases not linked to an outbreak were imported into the United States by international travelers and 2) for flights arriving in or traveling within the United States during April 30-August 2, 2022, after a global clade II mpox outbreak was detected in May 2022. A total of 113 persons (100 passengers and 13 crew members) traveled on 221 flights while they were infectious with mpox. CDC developed definitions for aircraft contacts based on proximity to mpox cases and flight duration, sent information about these contacts to U.S. health departments, and received outcome information for 1,046 (68%) of 1,538 contacts. No traveler was found to have acquired mpox via a U.S. flight exposure. For persons with mpox and their contacts who had departed from the United States, CDC forwarded contact information as well as details about the exposure event to destination countries to facilitate their own public health investigations. Findings from these aircraft contact investigations suggest that traveling on a flight with a person with mpox does not appear to constitute an exposure risk or warrant routine contact tracing activities. Nonetheless, CDC recommends that persons with mpox isolate and delay travel until they are no longer infectious. |
Cost-effectiveness of vaccinating adults aged 60 years and older against respiratory syncytial virus
Hutton DW , Prosser LA , Rose AM , Mercon K , Ortega-Sanchez IR , Leidner AJ , Havers FP , Prill MM , Whitaker M , Roper LE , Pike J , Britton A , Melgar M . Vaccine 2024 42 (24) 126294 Respiratory syncytial virus (RSV) causes substantial morbidity and mortality in older adults. In May 2023, two subunit RSV vaccines (Arexvy [GSK] and Abrysvo [Pfizer]) received approval from the U.S. Food and Drug Administration (FDA). In June 2023, ACIP recommended that adults aged ≥60 years may receive a single dose of RSV vaccine, using shared clinical decision-making. In support of development of this policy, our objective was to assess the cost-effectiveness of RSV vaccination in the general population in this age group. We used a decision-analytical model of RSV over a two-year timeframe using data from published literature, FDA documents, epidemiological databases, and manufacturer data. We tracked RSV-associated outpatient, emergency department, inpatient healthcare utilization, RSV-attributable deaths, quality-adjusted life-years lost (QALYs), and societal costs. The societal cost per QALY saved from RSV vaccination depended on age group and product: adults aged ≥60 years, $196,842 for GSK's vaccine and $176,557 for Pfizer's vaccine; adults ≥65 years, $162,138 for GSK and $146,543 for Pfizer; adults 60- <65 years, $385,829 for GSK and $331,486 for Pfizer. Vaccine efficacy, incidence of RSV hospitalization, and vaccine cost had the greatest influence on cost per QALY. Cost per QALY saved decreased as the age of those vaccinated increased. Inputs such as long-term efficacy are uncertain. RSV vaccination in adults aged ≥60 years may be cost-effective, particularly in those of more advanced age. Lower vaccine acquisition costs and persistent efficacy beyond two RSV seasons would render RSV vaccination more cost-effective for a broader target population.

Leptospirosis outbreak in aftermath of Hurricane Fiona - Puerto Rico, 2022
Jones FK , Medina AG , Ryff KR , Irizarry-Ramos J , Wong JM , O'Neill E , Rodríguez IA , Cardona I , Hernández L , Hernandez-Romieu AC , Phillips MT , Johansson MA , Bayleyegn T , Atherstone C , DeBord KR , Negrón ME , Galloway R , Adams LE , Marzán-Rodríguez M . MMWR Morb Mortal Wkly Rep 2024 73 (35) 763-768 Leptospirosis, an acute bacterial zoonotic disease, is endemic in Puerto Rico. Infection in approximately 10%-15% of patients with clinical disease progresses to severe, potentially fatal illness. Increased incidence has been associated with flooding in endemic areas around the world. In 2022, Hurricane Fiona, a Category 1 hurricane, made landfall and inundated Puerto Rico with heavy rainfall and severe flooding, increasing the risk for a leptospirosis outbreak. In response, the Puerto Rico Department of Health (PRDH) changed guidelines to make leptospirosis cases reportable within 24 hours, centralized the case investigation management system, and provided training and messaging to health care providers. To evaluate changes in risk for leptospirosis after Hurricane Fiona to that before the storm, the increase in cases was quantified, and patient characteristics and geographic distribution were compared. During the 15 weeks after Hurricane Fiona, 156 patients experienced signs and symptoms of leptospirosis and had a specimen with a positive laboratory result reported to PRDH. The mean weekly number of cases during this period was 10.4, which is 3.6 as high as the weekly number of cases during the previous 37 weeks (2.9). After Hurricane Fiona, the proportion of cases indicating exposure to potentially contaminated water increased from 11% to 35%, and the number of persons receiving testing increased; these factors likely led to the resulting overall surge in reported cases. Robust surveillance combined with outreach to health care providers after flooding events can improve leptospirosis case identification, inform clinicians considering early initiation of treatment, and guide public messaging to avoid wading, swimming, or any contact with potentially contaminated floodwaters. |

J Racial Ethn Health Disparities 2024 BACKGROUND: Differences in acute COVID-19 associated morbidity based on race, ethnicity, and gender have been well described; however, less is known about differences in subsequent longer term health-related quality of life and well-being. METHODS: This prospective cohort study included symptomatic adults tested for SARS-CoV-2 who completed baseline and 3-month follow-up surveys. Using the PROMIS-29 tool, a validated measure of health and well-being, we compared outcomes at 3 months and change in outcomes from baseline to 3 months among groups with different races, ethnicities, and/or sexes. RESULTS: Among 6044 participants, 4113 (3202 COVID +) were included. Among COVID + participants, compared to non-Hispanic White participants, Black participants had better PROMIS T-scores for cognitive function (3.6 [1.1, 6.2]) and fatigue (- 4.3 [- 6.6, - 2.0]) at 3 months and experienced more improvement in fatigue over 3 months (- 2.7 [- 4.7, - 0.8]). At 3 months, compared with males, females had worse PROMIS T-scores for cognitive function (- 4.1 [- 5.6, - 2.6]), physical function (- 2.1 [- 3.1, - 1.0]), social participation (- 2.8 [- 4.2, - 1.5]), anxiety (2.8 [1.5, 4.1]), fatigue (5.1 [3.7, 6.4]), and pain interference (2.0 [0.9, 3.2]). Females experienced less improvement in fatigue over 3 months (3.1 [2.0, 4.3]). Transgender/non-binary/other gender participants had worse 3-month scores in all domains except for sleep disturbance and pain interference. CONCLUSIONS: Three months after the initial COVID-19 infection, Black participants reported better cognitive function and fatigue, while females and other gender minoritized groups experienced lower well-being. Future studies are necessary to better understand how and why social constructs, specifically race, ethnicity, and gender, influence differences in COVID-19-related health outcomes.

National vaccination coverage among adolescents aged 13-17 years - National Immunization Survey-Teen, United States, 2023
Pingali C , Yankey D , Chen M , Elam-Evans LD , Markowitz LE , DeSisto CL , Schillie SF , Hughes M , Valier MR , Stokley S , Singleton JA . MMWR Morb Mortal Wkly Rep 2024 73 (33) 708-714 Based on safety and efficacy data, vaccinations are the best defense to protect persons and communities from serious vaccine-preventable diseases. The Advisory Committee on Immunization Practices recommends routine vaccination of adolescents aged 11-12 years with three vaccines including tetanus, diphtheria, and acellular pertussis vaccine; quadrivalent meningococcal conjugate vaccine; and human papillomavirus vaccine. CDC analyzed data from the 2023 National Immunization Survey-Teen for 16,658 adolescents aged 13-17 years (born during January 2005-December 2010) to assess vaccination coverage in 2023, recent trends in coverage by birth year, and trends in coverage by eligibility for the Vaccines for Children (VFC) program and birth year. In 2023, coverage with all routine vaccines recommended for adolescents was similar to coverage in 2022. Vaccination coverage among VFC-eligible adolescents was generally stable during the COVID-19 pandemic, except for a decrease in the percentage of VFC-eligible adolescents who were up to date with HPV vaccination by age 13 years among those born in 2010 compared with those born in 2007. Whereas coverage differences were found between VFC-eligible and non-VFC-eligible adolescents before the COVID-19 pandemic, coverage was similar among the most recent birth years in the survey. Providers should make strong recommendations for all routine vaccines and review adolescent vaccination records to verify if adolescents are up to date with all recommended vaccines. |
Comparison of the sensitivity and specificity of commercial anti-dengue virus IgG tests to identify persons eligible for dengue vaccination
Medina FA , Vila F , Adams LE , Cardona J , Carrion J , Lamirande E , Acosta LN , De León-Rodríguez CM , Beltran M , Grau D , Rivera-Amill V , Balmaseda A , Harris E , Madewell ZJ , Waterman SH , Paz-Bailey G , Whitehead S , Muñoz-Jordán JL . J Clin Microbiol 2024 e0059324 The Advisory Committee on Immunization Practices (ACIP) recommended that dengue pre-vaccination screening tests for Dengvaxia administration have at least 98% specificity and 75% sensitivity. This study evaluates the performance of commercial anti-DENV IgG tests to identify tests that could be used for pre-vaccination screening. First, for seven tests, we evaluated sensitivity and specificity in early convalescent dengue virus (DENV) infection, using 44 samples collected 7-30 days after symptom onset and confirmed by RT-PCR. Next, for the five best-performing tests and two additional tests (with and without an external test reader) that became available later, we evaluated performance to detect past dengue infection among a panel of 44 specimens collected in 2018-2019 from healthy 9- to 16-year-old children from Puerto Rico. Finally, a full-scale evaluation was done with the four best-performing tests using 400 specimens from the same population. We used virus focus reduction neutralization test and an in-house DENV IgG ELISA as reference standards. Of seven tests, five showed ≥75% sensitivity in detecting anti-DENV IgG in early convalescent specimens with low cross-reactivity to the Zika virus. For the detection of previous DENV infections, the tests with the highest performance were the Euroimmun NS1 IgG ELISA (sensitivity 84.5%, specificity 97.1%) and CTK Dengue IgG rapid test R0065C with the test reader (sensitivity 76.2% specificity 98.1%). There are IgG tests available that can be used to accurately classify individuals with previous DENV infection as eligible for dengue vaccination to support safe vaccine implementation. IMPORTANCE: The Advisory Committee on Immunization Practices (ACIP) has set forth recommendations that dengue pre-vaccination screening tests must exhibit at least 98% specificity and 75% sensitivity. Our research rigorously assesses the performance of various commercial tests against these benchmarks using well-characterized specimens from Puerto Rico. The findings from our study are particularly relevant given FDA approval and ACIP recommendation of Sanofi Pasteur's Dengvaxia vaccine, highlighting the need for accurate pre-vaccination screening tools. |
Vaccine effectiveness against anal HPV among men who have sex with men aged 18-45 years attending sexual health clinics in three United States cities, 2018-2023
DeSisto CL , Winer RL , Querec TD , Dada D , Pathela P , Asbel L , Lin J , Tang J , Iqbal A , Meites E , Unger ER , Markowitz LE . J Infect Dis 2024 BACKGROUND: We assessed human papillomavirus (HPV) vaccine effectiveness (VE) against anal HPV among men who have sex with men (MSM) in 2018-2023. METHODS: Residual anal specimens from MSM without HIV ages 18-45 years were tested for HPV. We calculated adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) for associations between vaccination (≥1 dose) and quadrivalent vaccine (4vHPV)-type prevalence adjusting for city, race/ethnicity, and non-vaccine-type HPV prevalence, stratified by age group (18-26, 27-45). VE was calculated as (1-aPR)x100. RESULTS: Among 2802 persons aged 18-26, 4vHPV-type prevalence was lower in those vaccinated at age <18 (aPR=0.13, CI: 0.08-0.22, VE=87%) and those vaccinated ≥2 years before specimen collection (aPR=0.52, CI: 0.42-0.64, VE=48%), compared with unvaccinated persons. Among 3548 persons aged 27-45, 4vHPV-type prevalence was lower in those vaccinated at ages 18-26 (aPR=0.68, CI: 0.57-0.82, VE=32%) and those vaccinated ≥2 years before specimen collection (aPR=0.66, CI: 0.57-0.77, VE=33%), compared with unvaccinated persons. While we observed no VE in persons vaccinated at age >26 overall, 4vHPV-type prevalence was lower in the subgroup vaccinated ≥2 years before specimen collection (aPR=0.71, CI: 0.56-0.89, VE=29%). CONCLUSIONS: We found high VE against anal 4vHPV-type prevalence among MSM aged 18-26 who were vaccinated at age <18. Lower VE was observed among MSM ages 27-45 who were vaccinated at age 18-26 or ≥2 years before specimen collection. While ideally vaccination should be given at younger ages, vaccination can prevent some future infections in this population. |
Trends in drug overdose deaths by intent and drug categories, United States, 1999‒2022
Nguyen A , Wang J , Holland KM , Ehlman DC , Welder LE , Miller KD , Stone DM . Am J Public Health 2024 e1-e5 Objectives. To examine trends in overdose deaths by intent and drug category to better understand the recent decrease in overdose suicides amid the overdose epidemic. Methods. We examined trends in rates of overdose deaths by intent (unintentional, suicide, or undetermined) across 9 drug categories from 1999 to 2022 using US National Vital Statistics System mortality data. Results. Unintentional overdoses involving synthetic opioids, polydrug toxicity involving synthetic opioids, psychostimulants, and cocaine increased exponentially with annual percentage changes ranging from 15.0% to 104.9% during 2010 to 2022. The death rates also increased for suicides involving these drugs, especially for psychostimulants (annual percentage change = 12.9% for 2010-2022; P < .001). However, these drugs accounted for relatively small percentages of overdose suicides. The leading drug categories among suicides were antidepressants, prescription opioids, and benzodiazepines, though these deaths have decreased or leveled off in recent years. Conclusions. Different drugs commonly involved in suicides and unintentional overdoses may contribute to their divergent trends. Public Health Implications. Amid the overdose epidemic, safe storage of medications remains a crucial strategy to prevent overdose suicides. The large increases in suicides involving psychostimulants warrant monitoring.

Brainstorm: A case of granulomatous encephalitis
Benoit Patrick , Wang Stephanie , Wang Catherine , Chakravarti Arpita , Villalba Julian A , Ali Ibne Karim M , Roy Shantanu , Sapp Sarah GH , Reagan-Steiner Sarah , Nelson Kristoff , Cayrol Romain , Luong Me-Linh , Grand'Maison Sophie , Desjardins Michaël . J Assoc Med Microbiol Infect Dis Can 2024 9 (2) 113-120 Background: Free-living amoebas (FLAs) can cause severe and fatal central nervous system infections that are difficult to diagnose. Methods: We present the case of a 74-year-old immunocompetent woman admitted for focal neurological symptoms with enhancing lesions in the right cerebellar hemisphere. A first cerebral biopsy showed granulomatous inflammation, but no microorganisms were identified. After transient clinical improvement, she eventually deteriorated 4 months after initial presentation, with an MRI confirming multiple new masses affecting all cerebral lobes. Results: A second brain biopsy revealed granulomatous and acute inflammation with organisms containing a large central nucleus with prominent karyosome, consistent with FLAs. Immunohistochemical and polymerase chain reaction assays performed at CDC were positive for Acanthamoeba spp, confirming the diagnosis of granulomatous amoebic encephalitis (GAE) caused by Acanthamoeba spp. The patient was treated with combination therapy recommended by CDC, but died a few days later. Upon histopathological rereview, amoebic cysts and trophozoites were identified by histochemical and immunohistochemical methods in the first cerebral biopsy. Conclusion: FLA infections can be challenging to diagnose because of the low incidence, non-specific clinical and radiological presentation, lack of accessible diagnostic tools, and clinicians' unfamiliarity. This case highlights the importance of recognizing FLA as a potential cause of granulomatous encephalitis, even in the absence of risk factors, as early treatment might be associated with favourable outcomes in case reports. When suspected, CDC laboratories offer tests to confirm the diagnosis promptly. | Historique : Les amibes libres peuvent causer des infections du système nerveux central graves et fatales qui sont difficiles à diagnostiquer. Méthodologie : Les auteurs présentent le cas d'une femme immunocompétente de 74 ans hospitalisée à cause de symptômes neurologiques focaux avec lésions rehaussantes dans l'hémisphère cérébelleux droit. Une première biopsie cérébrale a révélé une inflammation granulomateuse, mais aucun microorganisme n'a été décelé. Après une amélioration clinique transitoire, son état s'est détérioré quatre mois après la première consultation, et l'IRM a confirmé de multiples nouvelles masses touchant tous les lobes cérébraux. Résultats : Une deuxième biopsie cérébrale a révélé une inflammation granulomateuse aiguë par des organismes dont les gros noyaux centraux et les caryosomes volumineux étaient évocateurs d'amibes libres. L'immunohistochimie et l'amplification en chaîne par polymérase effectuées aux CDC se sont avérés positives pour Acanthamoeba spp, ce qui a confirmé un diagnostic d'encéphalite amibienne granulomateuse causée par Acanthamoeba spp. La patiente a reçu une polythérapie recommandée par les CDC, mais est malheureusement décédée quelques jours plus tard. À la reprise de l'analyse histopathologique, des kystes amibiens et des trophozoïtes ont été décelés dans la première biopsie cérébrale par des méthodes histochimiques et immunohistochimiques. Conclusion : Les infections par des amibes libres peuvent être difficiles à diagnostiquer en raison de leur faible incidence, de leur présentation clinique et radiologique non spécifique, de l'absence d'outils diagnostiques accessibles et de la méconnaissance des cliniciens. Ce cas renforce l'importance d'inclure les amibes libres dans les causes potentielles d'encéphalite granulomateuse, même en l'absence de facteurs de risque, car un traitement rapide a été associé à des résultats favorables dans certains rapports de cas. Lorsqu'on en soupçonne la présence, les laboratoires des CDC offrent des tests pour confirmer rapidement le diagnostic. |

Influenza Other Respir Viruses 2024 18 (7) e13305 BACKGROUND: The COVID-19 pandemic underscored the need for rapid and accurate diagnostic tools. In August 2020, the Abbott BinaxNOW COVID-19 Antigen Card test became available as a timely and affordable alternative for SARS-CoV-2 molecular testing, but its performance may vary due to factors including timing and symptomatology. This study evaluates BinaxNOW diagnostic performance in diverse epidemiological contexts. METHODS: Using RT-PCR as reference, we assessed performance of the BinaxNOW COVID-19 test for SARS-CoV-2 detection in anterior nasal swabs from participants of two studies in Puerto Rico from December 2020 to May 2023. Test performance was assessed by days post symptom onset, collection strategy, vaccination status, symptomatology, repeated testing, and RT-PCR cycle threshold (Ct) values. RESULTS: BinaxNOW demonstrated an overall sensitivity of 84.1% and specificity of 98.8%. Sensitivity peaked within 1-6 days after symptom onset (93.2%) and was higher for symptomatic (86.3%) than asymptomatic (67.3%) participants. Sensitivity declined over the course of infection, dropping from 96.3% in the initial test to 48.4% in testing performed 7-14 days later. BinaxNOW showed 99.5% sensitivity in participants with low Ct values (≤ 25) but lower sensitivity (18.2%) for participants with higher Cts (36-40). CONCLUSIONS: BinaxNOW demonstrated high sensitivity and specificity, particularly in early-stage infections and symptomatic participants. In situations where test sensitivity is crucial for clinical decision-making, nucleic acid amplification tests are preferred. These findings highlight the importance of considering clinical and epidemiological context when interpreting test results and emphasize the need for ongoing research to adapt testing strategies to emerging SARS-CoV-2 variants. |

JAMA Netw Open 2024 7 (7) e2423555 IMPORTANCE: Chronic symptoms reported following an infection with SARS-CoV-2, such as cognitive problems, overlap with symptoms included in the definition of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). OBJECTIVE: To evaluate the prevalence of ME/CFS-like illness subsequent to acute SARS-CoV-2 infection, changes in ME/CFS symptoms through 12 months of follow-up, and the association of ME/CFS symptoms with SARS-CoV-2 test results at the acute infection-like index illness. DESIGN, SETTING, AND PARTICIPANTS: This prospective, multisite, longitudinal cohort study (Innovative Support for Patients with SARS-CoV-2 Infections Registry [INSPIRE]) enrolled participants from December 11, 2020, to August 29, 2022. Participants were adults aged 18 to 64 years with acute symptoms suggestive of SARS-CoV-2 infection who received a US Food and Drug Administration-approved SARS-CoV-2 test at the time of illness and did not die or withdraw from the study by 3 months. Follow-up surveys were collected through February 28, 2023. EXPOSURE: COVID-19 status (positive vs negative) at enrollment. MAIN OUTCOME AND MEASURES: The main outcome was the weighted proportion of participants with ME/CFS-like illness based on the 2015 Institute of Medicine clinical case definition using self-reported symptoms. RESULTS: A total of 4378 participants were included in the study. Most were female (3226 [68.1%]). Mean (SD) age was 37.8 (11.8) years. The survey completion rates ranged from 38.7% (3613 of 4738 participants) to 76.3% (1835 of 4738) and decreased over time. The weighted proportion of participants identified with ME/CFS-like illness did not change significantly at 3 through 12 months of follow-up and was similar in the COVID-19-positive (range, 2.8%-3.7%) and COVID-19-negative (range, 3.1%-4.5%) groups. Adjusted analyses revealed no significant difference in the odds of ME/CFS-like illness at any time point between COVID-19-positive and COVID-19-negative individuals (marginal odds ratio range, 0.84 [95% CI, 0.42-1.67] to 1.18 [95% CI, 0.55-2.51]). CONCLUSIONS AND RELEVANCE: In this prospective cohort study, there was no evidence that the proportion of participants with ME/CFS-like illness differed between those infected with SARS-CoV-2 vs those without SARS-CoV-2 infection up to 12 months after infection. A 3% to 4% prevalence of ME/CFS-like illness after an acute infection-like index illness would impose a high societal burden given the millions of persons infected with SARS-CoV-2. |

Crit Care Explor 2024 6 (7) e1122 IMPORTANCE: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has evolved through multiple phases in the United States, with significant differences in patient centered outcomes with improvements in hospital strain, medical countermeasures, and overall understanding of the disease. We describe how patient characteristics changed and care progressed over the various pandemic phases; we also emphasize the need for an ongoing clinical network to improve the understanding of known and novel respiratory viral diseases. OBJECTIVES: To describe how patient characteristics and care evolved across the various COVID-19 pandemic periods in those hospitalized with viral severe acute respiratory infection (SARI). DESIGN: Severe Acute Respiratory Infection-Preparedness (SARI-PREP) is a Centers for Disease Control and Prevention Foundation-funded, Society of Critical Care Medicine Discovery-housed, longitudinal multicenter cohort study of viral pneumonia. We defined SARI patients as those hospitalized with laboratory-confirmed respiratory viral infection and an acute syndrome of fever, cough, and radiographic infiltrates or hypoxemia. We collected patient-level data including demographic characteristics, comorbidities, acute physiologic measures, serum and respiratory specimens, therapeutics, and outcomes. Outcomes were described across four pandemic variant periods based on a SARS-CoV-2 sequenced subsample: pre-Delta, Delta, Omicron BA.1, and Omicron post-BA.1. SETTING: Multicenter cohort of adult patients admitted to an acute care ward or ICU from seven hospitals representing diverse geographic regions across the United States. PARTICIPANTS: Patients with SARI caused by infection with respiratory viruses. MAIN OUTCOMES AND RESULTS: Eight hundred seventy-four adult patients with SARI were enrolled at seven study hospitals between March 2020 and April 2023. Most patients (780, 89%) had SARS-CoV-2 infection. Across the COVID-19 cohort, median age was 60 years (interquartile range, 48.0-71.0 yr) and 66% were male. Almost half (430, 49%) of the study population belonged to underserved communities. Most patients (76.5%) were admitted to the ICU, 52.5% received mechanical ventilation, and observed hospital mortality was 25.5%. As the pandemic progressed, we observed decreases in ICU utilization (94% to 58%), hospital length of stay (median, 26.0 to 8.5 d), and hospital mortality (32% to 12%), while the number of comorbid conditions increased. CONCLUSIONS AND RELEVANCE: We describe increasing comorbidities but improved outcomes across pandemic variant periods, in the setting of multiple factors, including evolving care delivery, countermeasures, and viral variants. An understanding of patient-level factors may inform treatment options for subsequent variants and future novel pathogens. |
Prevalence, risk factors, and impact of long COVID in a socially vulnerable community in Brazil: a prospective cohort study
Azambuja P , Bastos LSL , Batista-da-Silva AA , Ramos GV , Kurtz P , Dias CMC , da Silva EP , Arouca LE , Soares J , Sejvar JJ , Sigfrid L , Ranzani OT , Hamacher S , Bozza FA . Lancet Reg Health - Am 2024 37 Background: Long COVID is an emerging global public health issue. Socially vulnerable communities in low- and-middle-income countries were severely impacted by the pandemic and are underrepresented in research. This prospective study aimed to determine the prevalence of long COVID, its impact on health, and associated risk factors in one such community in Rio de Janeiro, Brazil. Methods: A total of 710 individuals aged 18 and older, with confirmed SARS-CoV-2 infection at least three months prior, were enrolled between November 25, 2021, and May 5, 2022. Participants were assessed via telephone or in person using a standardized questionnaire to evaluate their perception of recovery, symptoms, quality of life, and functional status. Findings: Twenty percent of participants did not feel fully recovered, 22% experienced new or persistent symptoms, 26% had worsened functional status, 18% had increased dyspnoea, and 32% reported a worse quality of life. Persistent symptoms included headache, cough, fatigue, muscle pain, and shortness of breath. Dyspnoea during the acute phase was the strongest independent predictor of worsening outcomes. Females and individuals with comorbidities were more likely to report worse recovery, functioning, dyspnoea, and quality of life. Interpretation: Our findings reveal a high burden of severe and persistent physical and mental health sequelae in a socially vulnerable community following COVID-19.

Med Mycol 2024 62 (6) The World Health Organization, in response to the growing burden of fungal disease, established a process to develop a fungal pathogen priority list. This systematic review aimed to evaluate the epidemiology and impact of infections caused by Talaromyces marneffei, Coccidioides species, and Paracoccidioides species. PubMed and Web of Sciences databases were searched to identify studies published between 1 January 2011 and 23 February 2021 reporting on mortality, complications and sequelae, antifungal susceptibility, preventability, annual incidence, and trends. Overall, 25, 17, and 6 articles were included for T. marneffei, Coccidioides spp. and Paracoccidioides spp., respectively. Mortality rates were high in those with invasive talaromycosis and paracoccidioidomycosis (up to 21% and 22.7%, respectively). Hospitalization was frequent in those with coccidioidomycosis (up to 84%), and while the duration was short (mean/median 3-7 days), readmission was common (38%). Reduced susceptibility to fluconazole and echinocandins was observed for T. marneffei and Coccidioides spp., whereas >88% of T. marneffei isolates had minimum inhibitory concentration values ≤0.015 μg/ml for itraconazole, posaconazole, and voriconazole. Risk factors for mortality in those with talaromycosis included low CD4 counts (odds ratio 2.90 when CD4 count <200 cells/μl compared with 24.26 when CD4 count <50 cells/μl). Outbreaks of coccidioidomycosis and paracoccidioidomycosis were associated with construction work (relative risk 4.4-210.6 and 5.7-times increase, respectively). In the United States of America, cases of coccidioidomycosis increased between 2014 and 2017 (from 8232 to 14 364/year). National and global surveillance as well as more detailed studies to better define sequelae, risk factors, outcomes, global distribution, and trends are required. |
Changes in maternity care policies and practices that support breastfeeding as measured by the Ten Steps to Successful Breastfeeding - United States, 2018-2022
Marks KJ , Gosdin L , O'Connor LE , Hamner HC , Grossniklaus DA . BMC Pregnancy Childbirth 2024 24 (1) 475 BACKGROUND: Experiences during the birth hospitalization affect a family's ability to establish and maintain breastfeeding. The Ten Steps to Successful Breastfeeding (Ten Steps) describe evidence-based hospital policies and practices shown to improve breastfeeding outcomes. We aim to describe hospitals' implementation of the Ten Steps, changes over time, and hospitals' implementation of a majority (≥ 6) of the Ten Steps by hospital characteristics and state. METHODS: The biennial Maternity Practices in Infant Nutrition and Care (mPINC) survey assesses all hospitals in the United States (including the District of Columbia and territories) that routinely provide maternity care services. We analyzed data from 2018, 2020, and 2022 survey cycles to describe trends in the prevalence of hospitals implementing maternity care policies and practices that are consistent with the Ten Steps. Differences were calculated using the absolute difference in percentage-points between 2018 and 2022. RESULTS: Between 2018 and 2022, the percentage of hospitals that implemented Step 2: Staff Competency and Step 5: Support Mothers with Breastfeeding increased 12 and 8 percentage points, respectively. The percentage of hospitals that implemented Step 6: Exclusive Breastfeeding Among Breastfed Infants was 7 percentage points lower in 2022 than 2018. Implementation of the remaining seven steps did not change by more than 5 percentage points in either direction between 2018 and 2022. Nationally, the percentage of hospitals that implemented ≥ 6 of the Ten Steps increased from 44.0% in 2018 to 51.1% in 2022. Differences were seen when comparing implementation of ≥ 6 of the Ten Steps by hospital characteristics including state, hospital size, and highest level of neonatal care offered.
