Projected outcomes of reduced-biopsy management of grade group 1 prostate cancer: Implications for relabeling
Zhao Y , Gulati R , Yang Z , Newcomb L , Zheng Y , Zhu K , Liu M , Heijnsdijk EAM , Haffner MC , Cooperberg M , Eggener SE , De Marzo AM , Kibel AS , Rizopoulos D , Hall IJ , Etzioni R . J Natl Cancer Inst 2024 BACKGROUND: Implications of relabeling grade group (GG) 1 prostate cancer as non-cancer will depend on the recommended active surveillance (AS) strategy. Whether relabeling should prompt de-intensifying, PSA-based active monitoring approaches is unclear. We investigated outcomes of biopsy-based AS strategies vs PSA-based active monitoring for GG1 diagnoses under different patient adherence rates. METHODS: We analyzed longitudinal PSA levels and time to GG ≥ 2 reclassification among 850 patients diagnosed with GG1 disease from the Canary Prostate Active Surveillance Study (2008-2013). We then simulated 20,000 patients over 12 years, comparing GG ≥ 2 detection under biennial biopsy against three PSA-based strategies:(1) PSA: biopsy for PSA change ≥20%/year, (2) PSA+MRI: MRI for PSA change ≥20%/year and biopsy for PI-RADS ≥3, and (3) Predicted risk: biopsy for predicted upgrading risk ≥10%. RESULTS: Under biennial biopsies and 20% dropout to active treatment, 17% of patients had a > 2-year delay in GG ≥ 2 detection. The PSA strategy reduced biopsies by 39% but delayed detection in 32% of patients. The PSA+MRI strategy cut biopsies by 52%, with a 34% delay. The predicted risk strategy reduced biopsies by 31%, with only an 8% delay. These findings are robust to biopsy sensitivity and confirmatory biopsy. CONCLUSIONS: PSA-based active monitoring could substantially reduce biopsy frequency; however, a precision strategy based on an individual upgrading risk is most likely to minimize delays in disease progression detection. This strategy may be preferred if AS is deintensified under relabeling, provided patient adherence remains unaffected. |
Traceback and testing of food epidemiologically linked to a norovirus outbreak at a wedding reception
Papafragkou E , Kita-Yarbro A , Yang Z , Chhabra P , Davis T , Blackmore J , Ziemer C , Klos R , Hall AJ , Vinjé J . J Food Prot 2024 100395 We investigated a suspected norovirus outbreak associated with a wedding reception in Wisconsin in May 2015. Fifty-six of 106 (53%) wedding attendees were interviewed and 23 (41%) reported symptoms consistent with norovirus infection. A retrospective cohort study identified fruit salad as the likely vehicle of infection (risk ratio 3.2, 95% confidence interval 1.1- 8.3). Norovirus was detected by real-time reverse transcription polymerase chain reaction (RT-qPCR) in stool specimens collected from four attendees and one food handler and in 12 leftover fruit salad samples from both an opened and a sealed container. Norovirus-positive clinical samples (n=4) were genotyped as GII.4 Sydney and norovirus-positive fruit salad samples (n=2) confirmed the presence of GII.4 norovirus by Sanger sequencing with 98% nucleotide (n=236) similarity in 5' end of ORF2 between fruit salad and clinical specimens. In conclusion, this comprehensive norovirus outbreak investigation combined epidemiologic, virologic, and environmental findings to traceback the contaminated food as the source of the outbreak. |
Genomic surveillance for SARS-CoV-2 variants: Circulation of Omicron XBB and JN.1 lineages - United States, May 2023-September 2024
Ma KC , Castro J , Lambrou AS , Rose EB , Cook PW , Batra D , Cubenas C , Hughes LJ , MacCannell DR , Mandal P , Mittal N , Sheth M , Smith C , Winn A , Hall AJ , Wentworth DE , Silk BJ , Thornburg NJ , Paden CR . MMWR Morb Mortal Wkly Rep 2024 73 (42) 938-945 CDC continues to track the evolution of SARS-CoV-2, including the Omicron variant and its descendants, using national genomic surveillance. This report summarizes U.S. trends in variant proportion estimates during May 2023-September 2024, a period when SARS-CoV-2 lineages primarily comprised descendants of Omicron variants XBB and JN.1. During summer and fall 2023, multiple descendants of XBB with immune escape substitutions emerged and reached >10% prevalence, including EG.5-like lineages by June 24, FL.1.5.1-like lineages by August 5, HV.1 lineage by September 30, and HK.3-like lineages by November 11. In winter 2023, the JN.1 variant emerged in the United States and rapidly attained predominance nationwide, representing a substantial genetic shift (>30 spike protein amino acid differences) from XBB lineages. Descendants of JN.1 subsequently circulated and reached >10% prevalence, including KQ.1-like and KP.2-like lineages by April 13, KP.3 and LB.1-like lineages by May 25, and KP.3.1.1 by July 20. Surges in COVID-19 cases occurred in winter 2024 during the shift to JN.1 predominance, as well as in summer 2023 and 2024 during circulation of multiple XBB and JN.1 descendants, respectively. The ongoing evolution of the Omicron variant highlights the importance of continued genomic surveillance to guide medical countermeasure development, including the selection of antigens for updated COVID-19 vaccines. |
Regional differences in autism and intellectual disability risk associated with cesarean section delivery
Bilder DA , Sullivan S , Hughes MM , Dalton S , Hall-Lande J , Nicholls C , Bakian AV . Autism Res 2024 Prior epidemiological studies investigating the association between delivery mode (i.e., vaginal birth and cesarean section [C-section]) and autism spectrum disorder (ASD) and intellectual disability (ID) risk have reported mixed findings. This study examined ASD and ID risks associated with primary and repeat C-section within diverse US regions. During even years 2000-2016, 8-years-olds were identified with ASD and/or ID and matched to birth records [ASD only (N = 8566, 83.6% male), ASD + ID (N = 3445, 79.5% male), ID only (N = 6158, 60.8% male)] using the Centers for Disease Control and Prevention's Autism and Developmental Disabilities Monitoring Network methodology. The comparison birth cohort (N = 1,456,914, 51.1% male) comprised all births recorded in the National Center for Health Statistics corresponding to birth years and counties in which surveillance occurred. C-section rates in the birth cohort demonstrated significant regional variation with lowest rates in the West. Overall models demonstrate increased odds of disability associated with primary and repeat C-section. Adjusted models, stratified by region, identified significant variability in disability likelihood associated with repeat C-section: increased odds occurred for all case groups in the Southeast, for ASD only and ID only in the Mid-Atlantic, and no case groups in the West. Regional variability in disability risk associated with repeat C-section coincides with differences in birth cohorts' C-section rates. This suggests increased likelihood of disability is not incurred by the procedure itself, but rather C-section serves as a proxy for exposures with regional variability that influence fetal development and C-section rates. |
A new tool for estimating the number of pregnant people in the United States
Strid P , Simeone RM , Hall R , Meeker JR , Ellington SR . Obstet Gynecol 2024 BACKGROUND: Knowing the approximate number of women of reproductive age (ie, 15-49 years) who are pregnant at a point in time in the United States can aid in emergency preparedness resource allocation. The Centers for Disease Control and Prevention (CDC) released a pregnancy estimator toolkit in 2012, which could be used to estimate the number of pregnant people in a geographic area at a point in time. This original toolkit did not account for pregnancy losses before 20 weeks of gestation; however, an updated toolkit released by the CDC in May 2024 uses a ratio of live births to estimate the number of pregnancy losses before 20 weeks at a point in time for improved estimation of total pregnant people at a point in time. INSTRUMENT: We used the CDC's updated reproductive health tool, "Estimating the Number of Pregnant Women in a Geographic Area." EXPERIENCE: Using publicly available data for 2020, we gathered the necessary input values, including total births, fetal deaths, and induced abortions, and applied the equation available in the CDC toolkit to estimate the number of pregnant people in the United States at any point in time in 2020. CONCLUSION: In 2020, there were 75,582,028 women of reproductive age in the United States, and we estimate that approximately 2,962,052 or 3.9% of women of reproductive age were pregnant at any point in time in the United States. |

Gon G , Dramowski A , Hornsey E , Graham W , Fardousi N , Aiken A , Allegranzi B , Anderson D , Bartram J , Bhattacharya S , Brogan J , Caluwaerts A , Padoveze MC , Damani N , Dancer S , Deeves M , Denny L , Feasey N , Hall L , Hopman J , Chettry LK , Kiernan M , Kilpatrick C , Mehtar S , Moe C , Nurse-Findlay S , Ogunsola F , Okwor T , Pascual B , Patrick M , Pearse O , Peters A , Pittet D , Storr J , Tomczyk S , Weiser TG , Yakubu H . Antimicrob Resist Infect Control 2024 13 (1) 112 Environmental cleaning is essential to patient and health worker safety, yet it is a substantially neglected area in terms of knowledge, practice, and capacity-building, especially in resource-limited settings. Public health advocacy, research and investment are urgently needed to develop and implement cost-effective interventions to improve environmental cleanliness and, thus, overall healthcare quality and safety. We outline here the CLEAN Group Consensus exercise yielding twelve urgent research questions, grouped into four thematic areas: standards, system strengthening, behaviour change, and innovation. |
Assessing attitudes and knowledge of mpox vaccine among unvaccinated men who have sex with men
Green CJ , Hall GC , Kachur R , Finley E , Furness BW , Merritt M , Lewis FMT . Sex Transm Dis 2024 BACKGROUND: The 2022 mpox outbreak disproportionately affected gay, bisexual, and other men who have sex with men (GBMSM). Mpox cases continue to be reported nationally. Vaccination is a tool to prevent the spread of and serious disease from mpox. To understand mpox vaccine uptake and hesitancy, a virtual focus group with unvaccinated GBMSM was conducted. METHODS: In November 2022, a 60-minute, virtual focus group was conducted within an artificial intelligence (AI) platform that engages participants in chat-based conversation. The AI system uses machine learning and natural language processing to analyze and provide results immediately to the moderator. Descriptive frequencies, cross-tabulations and qualitative themes were analyzed. RESULTS: Fifty-one GBMSM ages 18-55 participated, of whom 12 had attempted to get the mpox vaccine. The top barriers in accessing the vaccine included challenges in scheduling appointments (4/12), available vaccine locations (3/12), and transportation (2/12). Nine participants reported not wanting the vaccine and 22 were undecided; Of these, 15 (4/9 and 11/22, respectively) said they did not think they needed the vaccine due to low perceived risk or monogamy.. Among the undecided, after receiving health messaging about mpox, 12/22 said the messaging made them reconsider getting the vaccine. CONCLUSION: During an outbreak, many unvaccinated GBMSM who may be at increased risk for mpox either wanted the vaccine or, with appropriate health messaging, may be open to getting the vaccine. Messaging about mpox vaccine efficacy, potential side effects, and how to access the vaccine may improve vaccine uptake especially as cases continue to occur. |

Galang RR , Meeker JR , Leonard JS , Hansen S , Sayyad A , Waits G , McArdle CE , Hall RL . J Womens Health (Larchmt) 2024 This report describes opportunities to address emergency preparedness to incorporate the needs of pregnant and postpartum populations. This report briefly summarizes data on the impacts of weather and climate disasters on maternal and infant health and outlines opportunities for individuals, health care providers, and public health practitioners to increase capacity to prepare for these occurrences, which are becoming more frequent and costly. Specific resources from the U.S. Centers for Disease Control and Prevention's Division of Reproductive Health are shared to support individual preparedness, communication of disaster safety messages, and emergency preparedness planning capacity among health care providers and health departments. |
Household economic costs of norovirus gastroenteritis in two community cohorts in Peru, 2012-2019
Neyra J , Kambhampati AK , Calderwood LE , Romero C , Soto G , Campbell WR , Tinoco YO , Hall AJ , Ortega-Sanchez IR , Mirza SA . PLOS Glob Public Health 2024 4 (7) e0002748 While costs of norovirus acute gastroenteritis (AGE) to healthcare systems have been estimated, out-of-pocket and indirect costs incurred by households are not well documented in community settings, particularly in developing countries. We conducted active surveillance for AGE in two communities in Peru: Puerto Maldonado (October 2012-August 2015) and San Jeronimo (April 2015-April 2019). Norovirus AGE events with PCR-positive stool specimens were included. Data collected in follow-up interviews included event-related medical resource utilization, associated out-of-pocket costs, and indirect costs. There were 330 norovirus-associated AGE events among 3,438 participants from 685 households. Approximately 49% of norovirus events occurred among children <5 years of age and total cost to the household per episode was highest in this age group. Norovirus events cost a median of US $2.95 (IQR $1.04-7.85) in out-of-pocket costs and $12.58 (IQR $6.39-25.16) in indirect costs. Medication expenses accounted for 53% of out-of-pocket costs, and productivity losses accounted for 59% of the total financial burden on households. The frequency and associated costs of norovirus events to households in Peruvian communities support the need for prevention strategies including vaccines. Norovirus interventions targeting children <5 years of age and their households may have the greatest economic benefit. |
CDC prioritizes HIV prevention and treatment to reduce HIV disparities among cis-gender black women
Raiford JL , DiNenno E , Beer L , Bowman S , Johnson Lyons S , Anderson SKE , Powell N , Nickson R , Hall G , Neblett Fanfair R . J Womens Health (Larchmt) 2024 To succeed in ending the HIV epidemic in the United States, the Centers for Disease Control and Prevention (CDC) focuses on delivering combinations of scientifically proven, cost-effective, and scalable interventions to priority populations. Systemic factors continue to contribute to persistent health disparities and disproportionately higher rates of HIV diagnosis in some communities. The National HIV/AIDS Strategy has designated cis-gender Black women (CgBW) as a priority population to address the racial and ethnic inequities in HIV. This report presents the portfolio of projects, programs, and initiatives funded by the CDC's Division of HIV Prevention (DHP) to address disparities in HIV and improve health and QOL among CgBW. These funded activities include the development, planning, and implementation of HIV prevention programs, mass media campaigns, and behavioral interventions focused on CgBW. This report also summarizes DHP's community engagement, capacity building, and partnership efforts, and highlights research and surveillance activities focusing on CgBW. Finally, this report outlines future directions for CDC's efforts to improve access to HIV testing, treatment, and prevention for CgBW in the United States. |
Distilling the fundamentals of evidence-based public health policy
Kelly MA , Puddy RW , Siddiqi SM , Nelson C , Ntazinda AH , Kucik JE , Hall D , Murray CT , Tomoaia-Cotisel A . Public Health Rep 2024 333549241256751 Public health policy interventions are associated with many important public health achievements. To provide public health practitioners and decision makers with practical approaches for examining and employing evidence-based public health (EBPH) policy interventions, we describe the characteristics and benefits that distinguish EBPH policy interventions from programmatic interventions. These characteristics include focusing on health at a population level, focusing on upstream drivers of health, and involving less individual action than programmatic interventions. The benefits of EBPH policy interventions include more sustained effects on health than many programs and an enhanced ability to address health inequities. Early childhood education and universal preschool provide a case example that illustrates the distinction between EBPH policy and programmatic interventions. This review serves as the foundation for 3 concepts that support the effective use of public health policy interventions: applying core component thinking to understand the population health effects of EBPH policy interventions; understanding the influence of existing policies, policy supports, and the context in which a particular policy is implemented on the effectiveness of that policy; and employing a systems thinking approach to identify leverage points where policy implementation can have a meaningful effect. |
Women in coal mining-radiographic findings of women participants in the Coal Workers' Health Surveillance Program 1970-2022
Hall NB , Myers NT , Reynolds LE , Blackley DJ , Laney AS . J Womens Health (Larchmt) 2024 Objective: To describe the work experience and respiratory health of women coal miners in the United States using Coal Workers' Health Surveillance Program (CWHSP) data. Methods: Analysis included CWHSP participants with self-reported sex of female between January 1, 1970, and December 31, 2022, and examined radiographic surveillance, demographics, and job history. National Institute for Occupational Safety and Health-certified physicians classified chest radiographs. Results: Among 8,182 women participants, most worked <10 years and a majority reported working in non-dusty jobs. Among 3,392 with ≥1 year of coal mining tenure, 18 (0.5%) had evidence of pneumoconiosis, with no cases of progressive massive fibrosis. Conclusion: Women coal miners participating in the CWSHP had short mining careers and low pneumoconiosis prevalence. Few worked in the most dusty jobs, indicating limited exposure to coal mine dust. This underscores the need to explore women's roles in mining, and for improved gender-specific employment reporting. Such changes can enhance health and work conditions for women in male-dominated industries. |

McMorrow ML , Moline HL , Toepfer AP , Halasa NB , Schuster JE , Staat MA , Williams JV , Klein EJ , Weinberg GA , Clopper BR , Boom JA , Stewart LS , Selvarangan R , Schlaudecker EP , Michaels MG , Englund JA , Albertin CS , Mahon BE , Hall AJ , Sahni LC , Curns AT . Pediatrics 2024 BACKGROUND: The coronavirus disease 2019 pandemic disrupted respiratory syncytial virus (RSV) seasonality resulting in early, atypical RSV seasons in 2021 and 2022, with an intense 2022 peak overwhelming many pediatric healthcare facilities. METHODS: We conducted prospective surveillance for acute respiratory illness during 2016-2022 at 7 pediatric hospitals. We interviewed parents, reviewed medical records, and tested respiratory specimens for RSV and other respiratory viruses. We estimated annual RSV-associated hospitalization rates in children aged <5 years and compared hospitalization rates and characteristics of RSV-positive hospitalized children over 4 prepandemic seasons (2016-2020) to those hospitalized in 2021 or 2022. RESULTS: There was no difference in median age or age distribution between prepandemic and 2021 seasons. Median age of children hospitalized with RSV was higher in 2022 (9.6 months vs 6.0 months, P < .001). RSV-associated hospitalization rates were higher in 2021 and 2022 than the prepandemic average across age groups. Comparing 2021 to 2022, RSV-associated hospitalization rates were similar among children <2 years of age; however, children aged 24 to 59 months had significantly higher rates of RSV-associated hospitalization in 2022 (rate ratio 1.68 [95% confidence interval 1.37-2.00]). More RSV-positive hospitalized children received supplemental oxygen and there were more respiratory virus codetections in 2022 than in prepandemic seasons (P < .001 and P = .003, respectively), but there was no difference in the proportion hypoxemic, mechanically ventilated, or admitted to intensive care. CONCLUSIONS: The atypical 2021 and 2022 RSV seasons resulted in higher hospitalization rates with similar disease severity to prepandemic seasons. |
Advancing evidence-based public health policy: How core component thinking can illuminate the multilevel nature of public health policy
Puddy RW , Kelly MA , Nelson C , Ntazinda AH , Siddiqi S , Hall D , Murray CT , Kucik JE . Public Health Rep 2024 333549241247708 A growing body of literature uses the concept of core components to better understand small-scale programmatic interventions. Instead of interventions being viewed as unitary "black boxes," interventions are viewed as configurations of core components, which are the parts of interventions that carry their causal potential and therefore need to be reproduced with fidelity to produce the intended effect. To date, the concept of core components has not been as widely applied to public health policy interventions as it has to programmatic interventions. The purpose of this topical review is to familiarize public health practitioners and policy makers with the concept of core components as applied to public health policy interventions. Raising the profile of core component thinking can foster mindful adaptation and implementation of public health policy interventions while encouraging further research to enhance the supporting evidence base. We present 3 types of multilevel interactions in which the core components of a public health policy intervention produce effects at the population level by (1) seeking to directly affect individual behavior, (2) facilitating adoption of programmatic interventions by intermediaries, and (3) encouraging intermediaries to take action that can shape changes in upstream drivers of population health. Changing the unit of analysis from whole policies to core components can provide a basis for understanding how policies work and for facilitating novel evidence-generating strategies and rapid evidence reviews that can inform future adaptation efforts. |
Characteristics of healthcare personnel with SARS-CoV-2 infection: 10 emerging infections program sites in the United States, April 2020-December 2021
Chea N , Eure T , Alkis Ramirez R , Zlotorzynska M , Blazek GT , Nadle J , Lee J , Czaja CA , Johnston H , Barter D , Kellogg M , Emanuel C , Meek J , Brackney M , Carswell S , Thomas S , Fridkin SK , Wilson LE , Perlmutter R , Marceaux-Galli K , Fell A , Lovett S , Lim S , Lynfield R , Shrum Davis S , Phipps EC , Sievers M , Dumyati G , Myers C , Hurley C , Licherdell E , Pierce R , Ocampo VLS , Hall EW , Wilson C , Adre C , Kirtz E , Markus TM , Billings K , Plumb ID , Abedi GR , James-Gist J , Magill SS , Grigg CT . Infect Control Hosp Epidemiol 2024 1-9 BACKGROUND: Understanding characteristics of healthcare personnel (HCP) with SARS-CoV-2 infection supports the development and prioritization of interventions to protect this important workforce. We report detailed characteristics of HCP who tested positive for SARS-CoV-2 from April 20, 2020 through December 31, 2021. METHODS: CDC collaborated with Emerging Infections Program sites in 10 states to interview HCP with SARS-CoV-2 infection (case-HCP) about their demographics, underlying medical conditions, healthcare roles, exposures, personal protective equipment (PPE) use, and COVID-19 vaccination status. We grouped case-HCP by healthcare role. To describe residential social vulnerability, we merged geocoded HCP residential addresses with CDC/ATSDR Social Vulnerability Index (SVI) values at the census tract level. We defined highest and lowest SVI quartiles as high and low social vulnerability, respectively. RESULTS: Our analysis included 7,531 case-HCP. Most case-HCP with roles as certified nursing assistant (CNA) (444, 61.3%), medical assistant (252, 65.3%), or home healthcare worker (HHW) (225, 59.5%) reported their race and ethnicity as either non-Hispanic Black or Hispanic. More than one third of HHWs (166, 45.2%), CNAs (283, 41.7%), and medical assistants (138, 37.9%) reported a residential address in the high social vulnerability category. The proportion of case-HCP who reported using recommended PPE at all times when caring for patients with COVID-19 was lowest among HHWs compared with other roles. CONCLUSIONS: To mitigate SARS-CoV-2 infection risk in healthcare settings, infection prevention, and control interventions should be specific to HCP roles and educational backgrounds. Additional interventions are needed to address high social vulnerability among HHWs, CNAs, and medical assistants. |
Estimating hepatitis C prevalence in the United States, 2017-2020
Hall EW , Bradley H , Barker LK , Lewis K , Shealey J , Valverde E , Sullivan P , Gupta N , Hofmeister MG . Hepatology 2024 BACKGROUND AIMS: The National Health and Nutrition Examination Survey (NHANES) underestimates the true prevalence of hepatitis C virus (HCV) infection. By accounting for populations inadequately represented in NHANES, we created two models to estimate the national hepatitis C prevalence among US adults during 2017-2020. APPROACH RESULTS: The first approach (NHANES+) replicated previous methodology by supplementing hepatitis C prevalence estimates among the US noninstitutionalized civilian population with a literature review and meta-analysis of hepatitis C prevalence among populations not included in the NHANES sampling frame. In the second approach (persons who inject drugs [PWID] adjustment), we developed a model to account for underrepresentation of PWID in NHANES by incorporating the estimated number of adult PWID in the United States and applying PWID-specific hepatitis C prevalence estimates. Using the NHANES+ model, we estimated HCV RNA prevalence of 1.0% (95% confidence interval [CI]: 0.5%-1.4%) among US adults in 2017-2020, corresponding to 2,463,700 (95% CI: 1,321,700-3,629,400) current HCV infections. Using the PWID adjustment model, we estimated HCV RNA prevalence of 1.6% (95% CI: 0.9%-2.2%), corresponding to 4,043,200 (95% CI: 2,401,800-5,607,100) current HCV infections. CONCLUSIONS: Despite years of an effective cure, estimated prevalence of hepatitis C in 2017-2020 remains unchanged from 2013-2016 when using comparable methodology. When accounting for increased injection drug use, estimated prevalence of hepatitis C is substantially higher than previously reported. National action is urgently needed to expand testing, increase access to treatment, and improve surveillance, especially among medically underserved populations, to support hepatitis C elimination goals. |
Who gets sick from COVID-19? Sociodemographic correlates of severe adult health outcomes during Alpha- and Delta-variant predominant periods, 9/2020-11/2021
Wei SC , Freeman D , Himschoot A , Clarke KEN , Van Dyke ME , Adjemian J , Ahmad FB , Benoit TJ , Berney K , Gundlapalli AV , Hall AJ , Havers F , Henley SJ , Hilton C , Johns D , Opsomer JD , Pham HT , Stuckey MJ , Taylor CA , Jones JM . J Infect Dis 2024 229 (1) 122-132 BACKGROUND: Because COVID-19 case data do not capture most SARS-CoV-2 infections, the actual risk of severe disease and death per infection is unknown. Integrating sociodemographic data into analysis can show consequential health disparities. METHODS: Data were merged from September 2020 to November 2021 from 6 national surveillance systems in matched geographic areas and analyzed to estimate numbers of COVID-19-associated cases, emergency department visits, and deaths per 100 000 infections. Relative risks of outcomes per infection were compared by sociodemographic factors in a data set including 1490 counties from 50 states and the District of Columbia, covering 71% of the US population. RESULTS: Per infection with SARS-CoV-2, COVID-19-related morbidity and mortality were higher among non-Hispanic American Indian and Alaska Native persons, non-Hispanic Black persons, and Hispanic or Latino persons vs non-Hispanic White persons; males vs females; older people vs younger; residents in more socially vulnerable counties vs less; those in large central metro areas vs rural; and people in the South vs the Northeast. DISCUSSION: Meaningful disparities in COVID-19 morbidity and mortality per infection were associated with sociodemography and geography. Addressing these disparities could have helped prevent the loss of tens of thousands of lives. |

Carbapenem-resistant Acinetobacter baumannii complex in the United States - an epidemiological and molecular description of isolates collected through the Emerging Infections Program, 2019
Bulens SN , Campbell D , McKay SL , Vlachos N , Burgin A , Burroughs M , Padila J , Grass JE , Jacob JT , Smith G , Muleta DB , Maloney M , Macierowski B , Wilson LE , Vaeth E , Lynfield R , O'Malley S , Snippes Vagnone PM , Dale J , Janelle SJ , Czaja CA , Johnson H , Phipps EC , Flores KG , Dumyati G , Tsay R , Beldavs ZG , Maureen Cassidy P , Hall A , Walters MS , Guh AY , Magill SS , Lutgring JD . Am J Infect Control 2024 BACKGROUND: Understanding the epidemiology of carbapenem-resistant A. baumannii complex (CRAB) and the patients impacted is an important step towards informing better infection prevention and control practices and improving public health response. METHODS: Active, population-based surveillance was conducted for CRAB in 9 U.S. sites from January 1-December 31, 2019. Medical records were reviewed, isolates were collected and characterized including antimicrobial susceptibility testing and whole genome sequencing. RESULTS: Among 136 incident cases in 2019, 66 isolates were collected and characterized; 56.5% were from cases who were male, 54.5% were from persons of Black or African American race with non-Hispanic ethnicity, and the median age was 63.5 years. Most isolates, 77.2%, were isolated from urine, and 50.0% were collected in the outpatient setting; 72.7% of isolates harbored an acquired carbapenemase gene (aCP), predominantly bla(OXA-23) or bla(OXA-24/40); however, an isolate with bla(NDM) was identified. The antimicrobial agent with the most in vitro activity was cefiderocol (96.9% of isolates were susceptible). CONCLUSIONS: Our surveillance found that CRAB isolates in the U.S. commonly harbor an aCP, have an antimicrobial susceptibility profile that is defined as difficult-to-treat resistance, and epidemiologically are similar regardless of the presence of an aCP. |
Economic burden of acute gastroenteritis among members of integrated healthcare delivery system, United States, 2014-2016
Dickerson JF , Salas SB , Donald J , Groom HC , Lee MH , Mattison CP , Hall AJ , Schmidt MA . Emerg Infect Dis 2024 30 (5) 968-973 We conducted a large surveillance study among members of an integrated healthcare delivery system in Pacific Northwest of the United States to estimate medical costs attributable to medically attended acute gastroenteritis (MAAGE) on the day care was sought and during 30-day follow-up. We used multivariable regression to compare costs of MAAGE and non-MAAGE cases matched on age, gender, and index time. Differences accounted for confounders, including race, ethnicity, and history of chronic underlying conditions. Analyses included 73,140 MAAGE episodes from adults and 18,617 from children who were Kaiser Permanente Northwest members during 2014-2016. Total costs were higher for MAAGE cases relative to non-MAAGE comparators as were costs on the day care was sought and costs during follow-up. Costs of MAAGE are substantial relative to the cost of usual-care medical services, and much of the burden accrues during short-term follow-up. |
A programmatic update on COVID-19 vaccination in rural communities in the United States
Piasecki AM , Hall DM , Zajac J , Miller SA , Nilson JR . Vaccine 2024 When public health experts think of rural barriers to vaccines, they often initially focus on access, which makes sense with a new vaccine during a pandemic. This commentary highlights that there can be more complexity to vaccine uptake in rural communities. What follows are some examples of CDC's efforts to better understand rural health and learnings to inform ongoing vaccination efforts in rural communities. |
Evaluating acute viral gastroenteritis severity: Modified Vesikari and Clark scoring systems
Plancarte C , Stopczynski T , Hamdan L , Stewart LS , Rahman H , Amarin JZ , Chappell J , Wikswo ME , Dunn JR , Payne DC , Hall AJ , Spieker AJ , Halasa N . Hosp Pediatr 2024 OBJECTIVE: Acute gastroenteritis (AGE) is the second leading cause of death in children worldwide. Objectively evaluating disease severity is critical for assessing future interventions. We used data from a large, prospective surveillance study to assess risk factors associated with severe presentation using modified Vesikari score (MVS) and Clark score (CS) of severity. METHODS: From December 1, 2012 to June 30, 2016, AGE surveillance was performed for children between 15 days and 17 years old in the emergency, inpatient, and outpatient settings at Vanderbilt's Monroe Carell Jr. Children's Hospital in Nashville, TN. Stool specimens were tested for norovirus, sapovirus, rotavirus, and astrovirus. We compared demographic and clinical characteristics, along with the MVS and CS, by viral detection status and by setting. RESULTS: Of the 6309 eligible children, 4216 (67%) were enrolled, with 3256 (77%) providing a stool specimen. The median age was 1.9 years, 52% were male, and 1387 (43%) of the stool samples were virus positive. Younger age, male sex, hospitalization, and rotavirus detection were significantly associated with higher mean MVS and CS. Non-Hispanic Black race and ethnicity was associated with a lower mean MVS and CS as compared with non-Hispanic white race and ethnicity. Prematurity and enrollment in the ED were associated with higher mean CS. The 2 scoring systems were highly correlated. CONCLUSIONS: Rotavirus continues to be associated with more severe pediatric illness compared with other viral causes of AGE. MVS and CS systems yielded comparable results and can be useful tools to assess AGE severity. |
Health care utilization and clinical management of all-cause and norovirus-associated acute gastroenteritis within a US integrated health care system
Cates J , Mattison CP , Groom H , Donald J , Hall RP , Schmidt MA , Hall AJ , Naleway AL , Mirza SA . Open Forum Infect Dis 2024 11 (4) ofae151 BACKGROUND: Norovirus-associated acute gastroenteritis (AGE) exacts a substantial disease burden, yet the health care utilization for and clinical management of norovirus-associated AGE are not well characterized. METHODS: We describe the health care encounters and therapeutics used for patients with all-cause and norovirus-associated AGE in the Kaiser Permanente Northwest health system from 1 April 2014 through 30 September 2016. Medical encounters for patients with AGE were extracted from electronic health records, and encounters within 30 days of one another were grouped into single episodes. An age-stratified random sample of patients completed surveys and provided stool samples for norovirus testing. RESULTS: In total, 40 348 individuals had 52 509 AGE episodes; 460 (14%) of 3310 participants in the substudy tested positive for norovirus. An overall 35% of all-cause AGE episodes and 29% of norovirus-associated AGE episodes had ≥2 encounters. While 80% of norovirus-associated AGE episodes had at least 1 encounter in the outpatient setting, all levels of the health care system were affected: 10%, 22%, 10%, and 2% of norovirus-associated AGE episodes had at least 1 encounter in virtual, urgent care, emergency department, and inpatient settings, respectively. Corresponding proportions of therapeutic use between norovirus-positive and norovirus-negative episodes were 13% and 10% for intravenous hydration (P = .07), 65% and 50% for oral rehydration (P < .001), 7% and 14% for empiric antibiotic therapy (P < .001), and 33% and 18% for antiemetics (P < .001). CONCLUSIONS: Increased health care utilization and therapeutics are likely needed for norovirus-associated AGE episodes during peak norovirus winter seasons, and these data illustrate that effective norovirus vaccines will likely result in less health care utilization. |

Hum Vaccin Immunother 2024 20 (1) 2330138 Measurement of IgG antibodies against group B streptococcus (GBS) capsular polysaccharide (CPS) by use of a standardized and internationally accepted multiplex immunoassay is important for the evaluation of candidate maternal GBS vaccines in order to compare results across studies. A standardized assay is also required if serocorrelates of protection against invasive GBS disease are to be established in infant sera for the six predominant GBS serotypes since it would permit the comparison of results across the six serotypes. We undertook an interlaboratory study across five laboratories that used standardized assay reagents and protocols with a panel of 44 human sera to measure IgG antibodies against GBS CPS serotypes Ia, Ib, II, III, IV, and V. The within-laboratory intermediate precision, which included factors like the lot of coated beads, laboratory analyst, and day, was generally below 20% relative standard deviation (RSD) for all six serotypes, across all five laboratories. The cross-laboratory reproducibility was < 25% RSD for all six serotypes, which demonstrated the consistency of results across the different laboratories. Additionally, anti-CPS IgG concentrations for the 44-member human serum panel were established. The results of this study showed assay robustness and that the resultant anti-CPS IgG concentrations were reproducible across laboratories for the six GBS CPS serotypes when the standardized assay was used. |

Koneru A , Wells K , Amanda Carnes C , Drumhiller K , Chatham-Stephens K , Melton M , Oliphant H , Hall S , Dennison C , Fiscus M , Vogt T . Vaccine 2024 OBJECTIVE: This report highlights state and local practices for optimizing the pediatric COVID-19 vaccination program for children ages 6 months through 11 years. METHODS: State and local practices designed to optimize pediatric COVID-19 vaccine uptake were identified from a range of sources, including immunization program, CDC, and partner staff; and media stories or program descriptions identified via online searches. RESULTS: A range of practices were identified across different categories: provider-focused practices, school-based practices, jurisdiction or health department-based activities, community-focused practices involving partners, use of vaccination incentives, and Medicaid-related practices. CONCLUSIONS: Immunization programs and stakeholders implemented a variety of practices to meet the challenge of the pediatric COVID-19 vaccination program. The key findings may serve to inform not only the current pediatric COVID-19 vaccination program, but also future outbreak response work and routine immunization activities. |

Sci Rep 2024 14 (1) 8158 Plasmodium falciparum with the histidine rich protein 2 gene (pfhrp2) deleted from its genome can escape diagnosis by HRP2-based rapid diagnostic tests (HRP2-RDTs). The World Health Organization (WHO) recommends switching to a non-HRP2 RDT for P. falciparum clinical case diagnosis when pfhrp2 deletion prevalence causes ≥ 5% of RDTs to return false negative results. Tanzania is a country of heterogenous P. falciparum transmission, with some regions approaching elimination and others at varying levels of control. In concordance with the current recommended WHO pfhrp2 deletion surveillance strategy, 100 health facilities encompassing 10 regions of Tanzania enrolled malaria-suspected patients between February and July 2021. Of 7863 persons of all ages enrolled and providing RDT result and blood sample, 3777 (48.0%) were positive by the national RDT testing for Plasmodium lactate dehydrogenase (pLDH) and/or HRP2. A second RDT testing specifically for the P. falciparum LDH (Pf-pLDH) antigen found 95 persons (2.5% of all RDT positives) were positive, though negative by the national RDT for HRP2, and were selected for pfhrp2 and pfhrp3 (pfhrp2/3) genotyping. Multiplex antigen detection by laboratory bead assay found 135/7847 (1.7%) of all blood samples positive for Plasmodium antigens but very low or no HRP2, and these were selected for genotyping as well. Of the samples selected for genotyping based on RDT or laboratory multiplex result, 158 were P. falciparum DNA positive, and 140 had sufficient DNA to be genotyped for pfhrp2/3. Most of these (125/140) were found to be pfhrp2+/pfhrp3+, with smaller numbers deleted for only pfhrp2 (n = 9) or only pfhrp3 (n = 6). No dual pfhrp2/3 deleted parasites were observed. This survey found that parasites with these gene deletions are rare in Tanzania, and estimated that 0.24% (95% confidence interval: 0.08% to 0.39%) of false-negative HRP2-RDTs for symptomatic persons were due to pfhrp2 deletions in this 2021 Tanzania survey. These data provide evidence for HRP2-based diagnostics as currently accurate for P. falciparum diagnosis in Tanzania. |

Paediatr Perinat Epidemiol 2024 BACKGROUND: No data exist at the population level on what tests are used to aid in the diagnosis of autism spectrum disorder in community practice. OBJECTIVES: To describe autism spectrum disorder testing practices to inform autism spectrum disorder identification efforts. METHODS: Data are from the Autism and Developmental Disabilities Monitoring Network, a multi-site surveillance system reporting prevalence estimates and characteristics of 8-year-old children with autism spectrum disorder. Percentages of children with autism spectrum disorder who received any autism spectrum disorder test or a 'gold standard' test were calculated by site, sex, race, median household income, and intellectual ability status. Risk ratios were calculated to compare group differences. RESULTS: Of 5058 8-year-old children with autism spectrum disorder across 11 sites, 3236 (64.0%) had a record of any autism spectrum disorder test and 2136 (42.2%) had a 'gold standard' ADOS or ADI-R test. Overall, 115 children (2.3%) had both the ADOS and ADI-R in their records. Differences persisted across race, median household income, and intellectual ability status. Asian/Pacific Islander children had the highest percent receiving any ASD test (71.8%; other groups range: 57.4-66.0%) and White children had the highest percent receiving 'gold standard' tests (46.4%; other groups range: 35.6-43.2%). Children in low-income neighbourhoods had a lower percent of any test (62.5%) and 'gold standard' tests (39.4%) compared to medium (70.2% and 47.5%, respectively) and high (69.6% and 46.8%, respectively) income neighbourhoods. Children with intellectual disability had a lower percent of any ASD test (81.7%) and 'gold standard' tests (52.6%) compared to children without intellectual disability (84.0% and 57.6%, respectively). CONCLUSIONS: Autism spectrum disorder testing practices vary widely by site and differ by race and presence of co-occurring intellectual disability, suggesting opportunities to standardise and/or improve autism spectrum disorder identification practices. |

Parasit Vectors 2024 17 (1) 153 BACKGROUND: Recent studies point to the need to incorporate the detection of non-falciparum species into malaria surveillance activities in sub-Saharan Africa, where 95% of the world's malaria cases occur. Although malaria caused by infection with Plasmodium falciparum is typically more severe than malaria caused by the non-falciparum Plasmodium species P. malariae, P. ovale spp. and P. vivax, the latter may be more challenging to diagnose, treat, control and ultimately eliminate. The prevalence of non-falciparum species throughout sub-Saharan Africa is poorly defined. Tanzania has geographical heterogeneity in transmission levels but an overall high malaria burden. METHODS: To estimate the prevalence of malaria species in Mainland Tanzania, we randomly selected 1428 samples from 6005 asymptomatic isolates collected in previous cross-sectional community surveys across four regions and analyzed these by quantitative PCR to detect and identify the Plasmodium species. RESULTS: Plasmodium falciparum was the most prevalent species in all samples, with P. malariae and P. ovale spp. detected at a lower prevalence (< 5%) in all four regions; P. vivax was not detected in any sample. CONCLUSIONS: The results of this study indicate that malaria elimination efforts in Tanzania will need to account for and enhance surveillance of these non-falciparum species. |

Clin Infect Dis 2024 BACKGROUND: We aimed to determine if pre-existing immunocompromising conditions (ICCs) were associated with the presentation or outcome of patients with acute coronavirus disease 2019 (COVID-19) admitted for pediatric intensive care. METHODS: 55 hospitals in 30 U.S. states reported cases through the Overcoming COVID-19 public health surveillance registry. Patients <21 years admitted March 12, 2020-December 30, 2021 to the pediatric intensive care unit (PICU) or high acuity unit for acute COVID-19 were included. RESULTS: Of 1,274 patients, 105 (8.2%) had an ICC including 33 (31.4%) hematologic malignancies, 24 (22.9%) primary immunodeficiencies and disorders of hematopoietic cells, 19 (18.1%) nonmalignant organ failure with solid organ transplantation, 16 (15.2%) solid tumors and 13 (12.4%) autoimmune disorders. Patients with ICCs were older, had more underlying renal conditions, and had lower white blood cell and platelet counts than those without ICCs, but had similar clinical disease severity upon admission. In-hospital mortality from COVID-19 was higher (11.4% vs. 4.6%, p = 0.005) and hospitalization was longer (p = 0.01) in patients with ICCs. New major morbidities upon discharge were not different between those with and without ICC (10.5% vs 13.9%, p = 0.40). In patients with ICC, bacterial co-infection was more common in those with life-threatening COVID-19. CONCLUSIONS: In this national case series of patients <21 years of age with acute COVID-19 admitted for intensive care, existence of a prior ICCs were associated with worse clinical outcomes. Reassuringly, most patients with ICCs hospitalized in the PICU for severe acute COVID-19 survived and were discharged home without new severe morbidities. |
