Hurricane Ida, a Category 4 hurricane, made landfall in southern Louisiana in August of 2021, causing widespread wind damage and flooding. The objective of this study was to investigate knowledge, attitudes, and practices related to post-hurricane mold exposure and cleanup among residents and workers in areas of Louisiana affected by Hurricane Ida and assess changes in knowledge, attitudes, and practices that have occurred over the past 16 years since Hurricane Katrina. We conducted in-person interviews with 238 residents and 68 mold-remediation workers in areas in and around New Orleans to ask about their mold cleanup knowledge and practices, personal protective equipment use, and risk perceptions related to mold. Knowledge of recommended safety measures increased since the post-Katrina survey but adherence to recommended safety measures did not. Many residents and some workers reported using insufficient personal protective equipment when cleaning up mold despite awareness of the potential negative health effects of mold exposure.

The Black Church has long been an institution of refuge, mobilization, and healing in Black or African American communities. While health promotion interventions have been implemented in the Black Church, little is known about ways to incorporate faith into colorectal cancer (CRC) screening messages. Using modified boot camp translation, a community-based approach, we met with 27 members of the African Methodist Episcopal Church in Atlanta, Georgia, for in-person and virtual sessions to co-create faith-based CRC screening messages and identify channels for sharing information within the church community. Examples of messages developed included "Faith over fear" and "Honor God by taking care of your body." Identified dissemination channels included Sunday service, community events, and social media. Churches serve as key partners in delivering health information, as they are among the most trusted institutions within the Black or African American community.

OBJECTIVE: Pet ownership among people experiencing homelessness (PEH) is common, but access to shelter, veterinary care, and flea-preventative products for PEH who own pets in the US is not well described. We sought to evaluate current knowledge of fleas and flea-borne diseases and characterize practices around pets and service animals among staff at homeless shelters and outreach organizations. METHODS: In-person surveys were administered to staff at homeless shelters and on outreach teams in 7 states from August 2022 to April 2023 to evaluate knowledge, attitudes, and practices and to assess homeless shelter/organizational characteristics. RESULTS: Surveys were administered to 333 staff members at 60 homeless shelters and among 29 outreach teams. Seventy-eight percent of homeless shelters allowed pets or service animals. Only 2% of homeless shelters and 7% of outreach teams provided veterinary care; 15% of homeless shelters and 7% of outreach teams provided flea preventatives. Nearly three-quarters of surveyed homeless shelter staff responded that no steps were taken to treat fleas at their shelters. CONCLUSIONS: Veterinary care and availability of flea-preventative products are limited in homeless shelter and outreach organizations serving people experiencing homelessness. CLINICAL RELEVANCE: Pets of PEH might be at an increased risk of flea infestation and flea-borne diseases because of limited access to veterinary care and preventatives. Improving knowledge and access to flea prevention, screening, and treatment are critical to ensure PEH and their pets can consistently access homeless shelters or outreach services, and to prevent flea-borne disease transmission.

BACKGROUND AND OBJECTIVES: Blood donor cohorts are an underappreciated resource for surveillance and public health programming for infectious diseases. The incidence of hepatitis C virus (HCV) infection was evaluated in repeat blood donors in Georgia. MATERIALS AND METHODS: Using data from the national hepatitis C screening registry, we calculated overall hepatitis C incidence for 2017-2023 and annual incidence during 2017-2022 among adults who donated blood at least twice and had a nonreactive HCV antibody (anti-HCV) test result upon first screening and a subsequent anti-HCV test conducted in any location. Rates of anti-HCV seroconversion and current infection were calculated by year, sex, age group, and location of last HCV screening and expressed per 100,000 person-years (PY). RESULTS: Of 101,443 blood donors with ≥2 anti-HCV results,775 (0.8%) seroconverted to anti-HCV reactive, of whom 403 (52.0%) had current infection. Incidence of anti-HCV seroconversion decreased from 408 per 100,000 PY in 2017 to 218 per 100,000 PY in 2022 and incidence of infection decreased from 172 per 100,000 PY in 2017 to 118 per 100,000 PY in 2022. Males, persons aged 18-39 years, and people last tested for HCV in prisons had the highest incidence rates for anti-HCV seroconversion and HCV infection, while persons last screened in blood banks and during antenatal care had the lowest. CONCLUSION: Despite the observed decline, incidence of HCV infection among repeat blood donors remains high in specific subgroups. Hepatitis C prevention, screening and treatment interventions need to particularly focus on incarcerated populations and young adults in Georgia.

Comprehensive prenatal care incorporates recommended vaccines to help protect the mother, the pregnancy, and the infant from adverse health outcomes and severe illness from vaccine preventable diseases (VPDs). However, vaccinations during pregnancy remain underutilized, often influenced by concerns about vaccine safety and low perception of disease risk. Self-reported vaccine hesitancy among pregnant people in the United States has significantly increased in the last few years, and influenza and Tdap (tetanus, diphtheria, and pertussis) vaccination rates have declined. Furthermore, the number of vaccines routinely recommended during pregnancy has expanded. Communication strategies tailored to pregnant people may help build vaccine confidence among pregnant people and their health care providers. While characteristics and perceptions associated with hesitancy to vaccinate during pregnancy are documented in existing literature, more information is needed on promising communication practices preferred by subgroups of pregnant persons, particularly Black pregnant people who have higher rates of illness from VPDs and greater risk of pregnancy-related complications. This article summarizes literature on the current landscape of prenatal vaccination, discusses qualitative findings from focus groups with non-Hispanic Black pregnant people, and describes promising practices for communicating with this group about vaccination. Promising practices include specifying the benefits of vaccination for both the pregnant person and the infant, outlining potential risks, and emphasizing the overall importance of vaccination during pregnancy, while also acknowledging that many non-Hispanic Black pregnant people may have health concerns they perceive as superseding vaccination.

BACKGROUND: Acute gastroenteritis (AGE) is a major medical condition for travellers worldwide, particularly travellers to low- and middle-income countries. Norovirus (NoV) is the most common cause of viral AGE in older children and adults, but data on prevalence and impact amongst travellers is limited. METHODS: Prospective, multi-site, observational cohort study conducted 2015-2017, amongst adult international travellers from the US and Europe to areas of moderate to high risk of travel-acquired AGE. Participants provided self-collected pre-travel stool samples and self-reported AGE symptoms whilst travelling. Post-travel stool samples were requested from symptomatic subjects and a sample of asymptomatic travellers within 14 days of return. Samples were tested for NoV by RT-qPCR, genotyped if positive and tested for other common enteric pathogens by Luminex xTAG GPP. RESULTS: Of the 1109 participants included, 437 (39.4%) developed AGE symptoms resulting in an overall AGE incidence of 24.7 per 100 person-weeks [95% confidence interval (CI): 22.4; 27.1]. In total, 20 NoV-positive AGE cases (5.2% of those tested) were identified at an incidence of 1.1 per 100 person-weeks (95% CI: 0.7; 1.7). NoV-positive samples belonged mostly to genogroup GII (18, 85.7%); None of the 13 samples sequenced belonged to genotype GII.4. Clinical severity of AGE was higher for NoV-positive than for NoV-negative cases (mean modified Vesikari Score 6.8 vs 4.9) with more cases classified as severe or moderate (25% vs 6.8%). In total, 80% of NoV-positive participants (vs 38.9% in NoV-negative) reported at least moderate impact on travel plans. CONCLUSIONS: AGE is a prevalent disease amongst travellers with a small proportion associated with NoV. Post-travel stool sample collection timing might have influenced the low number of NoV cases detected; however, NoV infections resulted in high clinical severity and impact on travel plans. These results may contribute to targeted vaccine development and the design of future studies on NoV epidemiology.

BACKGROUND: Hypertension affects nearly half of US adults yet remains inadequately controlled in over three-quarters of these cases. This study aimed to assess the association between adherence to antihypertensive medications and total medical costs, health care use, and productivity-related outcomes. METHODS AND RESULTS: We conducted cross-sectional analyses using MarketScan databases, which included individuals aged 18 to 64 years with noncapitated health insurance plans in 2019. Adherence was defined as ≥80% medication possession ratio for prescribed antihypertensive medications. We used a generalized linear model to estimate total medical costs, a negative binomial model to estimate health care use (emergency department visits and inpatient admissions), an exponential hurdle model to estimate productivity-related outcomes (number of sick absences, short-term disability, long-term disability), and a 2-part model to estimate productivity-related costs in 2019 US dollars. All models were adjusted for age, sex, urbanicity, census region, and comorbidities. We reported average marginal effects for outcomes related to antihypertensive medication adherence. Among 379 503 individuals with hypertension in 2019, 54.4% adhered to antihypertensives. Per person, antihypertensive medication adherence was associated with $1441 lower total medical costs, $11 lower sick absence costs, $291 lower short-term disability costs, and $69 lower long-term disability costs. Per 1000 individuals, medication adherence was associated with lower health care use, including 200 fewer emergency department visits and 90 fewer inpatient admissions, and productivity-related outcomes, including 20 fewer sick absence days and 442 fewer short-term disability days. CONCLUSIONS: Adherence to antihypertensives was consistently associated with lower total medical costs, reduced health care use, and improved productivity-related outcomes.

Common methods to collect data include quantitative, qualitative, and mixed method approaches. Although it is common to complete data collection in-person, the onset of COVID-19 has resulted in the increased use of online modalities. Qualitative research is commonly gathered through individual or focus group interviews. However, best practices outlining strategies when conducting online focus groups and approaches to address issues specific to online research (i.e., scammers) are limited. Due to the growing use of data collection through such means, it is imperative to draw out specific strategies that could regulate data quality and reduce the chances of scamming. The current article addresses this practical gap by providing a synthesis of the available literature on online focus groups that document best practices and suggestions to deal with scammers which is currently missing from the literature. The goal was to provide initial suggestions to improve data quality of online focus groups by examining the available literature that outlines best practices, addresses the issues of scammers, and to provide a concise and comprehensive overview of identified literature The article is organized beginning with a review of the literature. The research is then synthesized including an outline of best practices and strategies to address scammers when engaging in online focus groups. The article closes with a discussion of the significance of the review, limitations, and article summary. Scammers are prevalent in online spaces. Although this article provides a preliminary outline of suggestions from the literature, more research is necessary that provides specific examples of how challenges have been addressed and the impact of including the recommended strategies on the research process and outcomes. © 2024, Ludomedia EN.

The landscape of research on the benefits of influenza vaccines and antivirals to protect pregnant persons and infants has increased in recent years, while influenza vaccination rates and antiviral usage have declined. Pregnant people and infants <6 months of age are at increased risk of hospitalization with influenza, making protection of this population essential. Maternal influenza vaccination at any time during pregnancy is the best way to reduce the risk of influenza and severe influenza in both pregnant people and their infants <6 months of age. Influenza antiviral medications for pregnant people and infants are also recommended as early as possible if influenza is confirmed or suspected. This report will update on the current research on the benefits of influenza vaccination during pregnancy and influenza antiviral medication for the pregnant person and infant, current Advisory Committee on Immunization Practices recommendations for influenza vaccination in pregnancy and vaccination coverage rates, current influenza antiviral medication guidance and usage rates in pregnancy and among infants, and future directions for influenza pregnancy research. With over half a century of maternal influenza vaccination in the United States, we have improved protection for pregnant persons and infants against influenza, but we still have room for improvement and optimization with new challenges to overcome following the COVID-19 pandemic. By continuing to fill research gaps and increase vaccination coverage and antiviral usage, there is potential for significant reductions in the domestic and global burden of influenza in pregnant persons and infants.

BACKGROUND: Borealpox virus (BRPV, formerly known as Alaskapox virus) is a zoonotic member of the Orthopoxvirus genus first identified in a person in 2015. In the six patients with infection previously observed BRPV involved mild, self-limiting illness. We report the first fatal BRPV infection in an immunosuppressed patient. METHODS: A man aged 69 years from Alaska's Kenai Peninsula was receiving anti-CD20 therapy for chronic lymphocytic leukemia. He presented to care for a tender, red papule in his right axilla with increasing induration and pain. The patient failed to respond to multiple prescribed antibiotic regimens and was hospitalized 65 days postsymptom onset for progression of presumed infectious cellulitis. BRPV was eventually detected through orthopoxvirus real-time polymerase chain reaction testing of mucosal swabs. He received combination antiviral therapy, including 21 days of intravenous tecovirimat, intravenous vaccinia immunoglobulin, and oral brincidofovir. Serial serology was conducted on specimens obtained posttreatment initiation. FINDINGS: The patient's condition initially improved with plaque recession, reduced erythema, and epithelization around the axillary lesion beginning one-week post-therapy. He later exhibited delayed wound healing, malnutrition, acute renal failure, and respiratory failure. He died 138 days postsymptom onset. Serologic testing revealed no evidence the patient generated a humoral immune response. No secondary cases were detected. CONCLUSION: This report demonstrates that BRPV can cause overwhelming disseminated infection in certain immunocompromised patients. Based on the patient's initial response, early BRPV identification and antiviral therapies might have been beneficial. These therapies, in combination with optimized immune function, should be considered for patients at risk for manifestations of BRPV.

PROBLEM/CONDITION: Seasonal influenza accounts for 9.3 million-41 million illnesses, 100,000-710,000 hospitalizations, and 4,900-51,000 deaths annually in the United States. Since 2003, the Influenza Hospitalization Surveillance Network (FluSurv-NET) has been conducting population-based surveillance for laboratory-confirmed influenza-associated hospitalizations in the United States, including weekly rate estimations and descriptions of clinical characteristics and outcomes for hospitalized patients. However, a comprehensive summary of trends in hospitalization rates and clinical data collected from the surveillance platform has not been available. REPORTING PERIOD: 2010-11 through 2022-23 influenza seasons. DESCRIPTION OF SYSTEM: FluSurv-NET conducts population-based surveillance for laboratory-confirmed influenza-associated hospitalizations among children and adults. During the reporting period, the surveillance network included 13-16 participating sites each influenza season, with prespecified geographic catchment areas that covered 27 million-29 million persons and included an estimated 8.8%-9.5% of the U.S. population. A case was defined as a person residing in the catchment area within one of the participating states who had a positive influenza laboratory test result within 14 days before or at any time during their hospitalization. Each site abstracted case data from hospital medical records into a standardized case report form, with selected variables submitted to CDC on a weekly basis for rate estimations. Weekly and cumulative laboratory-confirmed influenza-associated hospitalization rates per 100,000 population were calculated for each season from 2010-11 through 2022-23 and stratified by patient age (0-4 years, 5-17 years, 18-49 years, 50-64 years, and ≥65 years), sex, race and ethnicity, influenza type, and influenza A subtype. During the 2020-21 season, only the overall influenza hospitalization rate was reported because case counts were insufficient to estimate stratified rates. RESULTS: During the 2010-11 to 2022-23 influenza seasons, laboratory-confirmed influenza-associated hospitalization rates varied significantly across seasons. Before the COVID-19 pandemic, hospitalization rates per 100,000 population ranged from 8.7 (2011-12) to 102.9 (2017-18) and had consistent seasonality. After SARS-CoV-2 emerged, the hospitalization rate for 2020-21 was 0.8, and the rate did not return to recent prepandemic levels until 2022-23. Inconsistent seasonality also was observed during 2020-21 through 2022-23, with influenza activity being very low during 2020-21, extending later than usual during 2021-22, and occurring early during 2022-23. Molecular assays, particularly multiplex standard molecular assays, were the most common influenza test type in recent seasons, increasing from 12% during 2017-18 for both pediatric and adult cases to 43% and 55% during 2022-23 for pediatric and adult cases, respectively. During each season, adults aged ≥65 years consistently had the highest influenza-associated hospitalization rate across all age groups, followed in most seasons by children aged 0-4 years. Black or African American and American Indian or Alaska Native persons had the highest age-adjusted influenza-associated hospitalization rates across these seasons. Among patients hospitalized with influenza, the prevalence of at least one underlying medical condition increased with increasing age, ranging from 36.9% among children aged 0-4 years to 95.4% among adults aged ≥65 years. Consistently across each season, the most common underlying medical conditions among children and adolescents were asthma, neurologic disorders, and obesity. The most common underlying medical conditions among adults were hypertension, obesity, chronic metabolic disease, chronic lung disease, and cardiovascular disease. The proportion of FluSurv-NET patients with acute respiratory signs and symptoms at hospital admission decreased from 90.6% during 2018-19 to 83.2% during 2022-23. Although influenza antiviral use increased during the 2010-11 through the 2017-18 influenza seasons, it decreased from 90.2% during 2018-19 to 79.1% during 2022-23, particularly among children and adolescents. Admission to the intensive care unit, need for invasive mechanical ventilation, and in-hospital death ranged from 14.1% to 22.3%, 4.9% to 11.1%, and 2.2% to 3.5% of patients hospitalized with influenza, respectively, during the reported surveillance period. INTERPRETATIONS: Influenza continues to cause severe morbidity and mortality, particularly in older adults, and disparities have persisted in racial and ethnic minority groups. Persons with underlying medical conditions represented a large proportion of patients hospitalized with influenza. Increased use of multiplex tests and other potential changes in facility-level influenza testing practices (e.g., influenza screening at all hospital admissions) could have implications for the detection of influenza infections among hospitalized patients. Antiviral use decreased in recent seasons, and explanations for the decrease should be further evaluated. PUBLIC HEALTH ACTION: Continued robust influenza surveillance is critical to monitor progress in efforts to encourage antiviral treatment and improve clinical outcomes for persons hospitalized with influenza. In addition, robust influenza surveillance can potentially reduce disparities by informing efforts to increase access to preventive measures for influenza and monitoring any subsequent changes in hospitalization rates.

BACKGROUND: Previous estimates of vaccine effectiveness (VE) against asymptomatic influenza virus infection based on seroconversion have varied widely and may be biased. We estimated 2022-2023 influenza VE against illness and asymptomatic infection in a prospective cohort. METHODS: In the HEROES-RECOVER cohort, adults at increased occupational risk of influenza exposure across 7 US sites provided weekly symptom reports and nasal swabs for reverse transcription-polymerase chain reaction (RT-PCR) influenza testing. Laboratory-confirmed influenza virus infections were classified as symptomatic (≥1 symptom) or asymptomatic during the week of testing. Participants reported demographic information and vaccination through surveys; most sites verified vaccination through medical record and immunization registry review. Person-time was calculated as days from the site-specific influenza season start (September-October 2022) through date of infection, study withdrawal, or season end (May 2023). We compared influenza incidence among vaccinated versus unvaccinated participants overall, by symptom status, and by influenza A subtype, using Cox proportional hazards regression adjusted for site and occupation. We estimated VE as (1 - adjusted hazard ratio) × 100%. RESULTS: In total, 269 of 3785 (7.1%) participants had laboratory-confirmed influenza, including 263 (98%) influenza A virus infections and 201 (75%) symptomatic illnesses. Incidence of laboratory-confirmed influenza illness among vaccinated versus unvaccinated participants was 23.7 and 33.2 episodes per 100 000 person-days, respectively (VE: 38%; 95% CI: 15%-55%). Incidence of asymptomatic influenza virus infection was 8.0 versus 11.6 per 100 000 (VE: 13%; 95% CI: -47%, 49%). CONCLUSIONS: Vaccination reduced incidence of symptomatic but not asymptomatic influenza virus infection, suggesting that influenza vaccination attenuates progression from infection to illness.

We evaluated HIV DNA levels in individuals who received long-acting cabotegravir (CAB-LA) or tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) pre-exposure prophylaxis in the HPTN 083 and 084 trials and had HIV DNA testing performed to help determine HIV status. HIV DNA testing was performed using peripheral blood mononuclear cell (PBMC) samples collected after a reactive HIV test was obtained at a study site. DNA was quantified using droplet digital PCR (lower limit of detection [LLOD]: 4.09 copies/million PBMCs). Final HIV status and the timing of the first HIV-positive visit were determined by an independent adjudication committee based on HIV test results from real-time site testing and retrospective testing at a centralized laboratory. HIV DNA testing was performed for 133 participants [21 HIV-positive (7 CAB-LA arm, 14 TDF/FTC arm) and 112 HIV-negative; 1-6 tests/person]. For persons with HIV, the time between the first HIV-positive visit and collection of the first sample for DNA testing was a median of 81 days for those receiving CAB-LA (range 41-246) and 11 days for those receiving TDF/FTC (range 3-127). Four (57.1%) of the seven CAB-LA cases with infection had a low initial DNA result [three detected <LLOD; one near the LLOD (4.2 copies/10(6) PBMCs); in 2/4 cases, the DNA level was still <10 copies/10(6) PBMCs ≥40 weeks after the first HIV-positive visit. In contrast, only 3/14 (21.4%) of the TDF/FTC cases had a low or negative initial DNA test result (one not detected; two <10 copies/10(6) PBMCs). In this study, the time between the first HIV-positive visit and the first DNA test was longer in the CAB-LA cases than the TDF/FTC cases. Despite this difference, low or undetectable DNA levels were more frequently observed in the CAB-LA cases. This suggests that CAB-LA exposure may limit seeding of the HIV reservoir in early infection.

BACKGROUND: A sharp increase in reported brucellosis incidence was observed in northwestern Tajikistan (from 1.0/100,000 people in January-May 2022 to 32.7/100,000 in January-May 2023). Most (82%) cases were from the same remote mountainous village (population = 10,712). The aim of this study was to identify risk factors for brucellosis infection and mitigate disease risk. METHODS: Using a case-control design, we conducted face-to-face interviews and collected blood samples during May-June 2023. Fifty-seven cases and 114 controls were recruited. Cases were the first person in a household diagnosed with brucellosis during February-June 2023 with positive serum agglutination test and antibody titers ≥1/160 from blood samples. Two controls were selected for each case (neighbors from different households matched by age and sex). Controls testing positive were excluded and replaced. We conducted conditional multivariable logistic regression to calculate adjusted odds ratio (AOR) and 95% confidence intervals (CI). RESULTS: Among the 87 brucellosis patients reported, 57 (66%) agreed to participate and didn't have secondary cases in the household. Of the 57 cases, 68% were 15-44 years old, and 44% were male. Cases peaked in May 2023. Common symptoms were joint pain (95%), fever (84%), weakness (72%), and night sweats (65%). Of selected controls, 13% tested positive and were excluded. All cases and 94% of controls owned livestock (mostly cattle, sheep, or goats); no animals had not been vaccinated in the past 5 years. Brucellosis was associated with consumption of both homemade kaymak (clotted cream) and home-raised meat compared with neither (AOR: 59 [95%CI: 4.3-798], p < 0.01), home-raised meat but not kaymak compared with neither (AOR: 54 [4.0-731], p < 0.01), and involvement in animal slaughter compared with no involvement (AOR: 36 [2.8-461], p < 0.01). CONCLUSION: Contact with unvaccinated livestock or consumption of their products was a key contributor to this outbreak in a remote village of Tajikistan. With 13% of controls testing positive, true incidence was likely greater than reported. Following our investigation, a brucellosis awareness education campaign and animal vaccination campaigns were carried out in the region and only one case was reported in September 2023.

In the United States, states and local jurisdictions set vaccination requirements for school attendance, conditions and procedures for exemptions from these requirements, grace periods for submitting documentation, and provisional enrollment for students who need more time to be vaccinated. States annually report data to CDC on the number of children in kindergarten who meet, are exempt from, or are in the process of meeting requirements. Data reported by 49 states and the District of Columbia (DC) for the 2023-24 school year were used for national- and state-level estimates of the following measures: complete vaccination with required doses of measles, mumps, and rubella vaccine (MMR), diphtheria, tetanus, and acellular pertussis vaccine (DTaP), poliovirus vaccine (polio), and varicella vaccine (VAR); exemptions from vaccination; and school attendance while meeting requirements. The 2023-24 kindergarten class became age-eligible to complete most state-required vaccinations during the COVID-19 pandemic, after schools had returned to routine in-person learning. Compared with approximated national coverage levels across all reported vaccines for the 2019-20 (95%) and 2022-23 (93%) school years, coverage dropped below 93% for the 2023-24 school year, ranging from 92.3% for DTaP to 92.7% for MMR. Exemptions increased to 3.3%, compared with those during the 2022-23 (3.0%) and 2021-22 school years (2.6%). Coverage with MMR, DTaP, polio, and VAR decreased in 35, 32, 33, and 36 jurisdictions, respectively, compared with the 2022-23 school year. Exemptions increased in 41 jurisdictions, with 14 reporting that >5% of kindergartners had an exemption from one or more vaccine. Efforts by health departments, schools, and providers are needed to ensure that students begin school fully vaccinated.

A global outbreak of clade II mpox associated with sexual contact, disproportionately affecting gay, bisexual, and other men who have sex with men (MSM), has been ongoing since May 2022. Information on types of contact most associated with transmission is limited. This report used data from a multijurisdictional vaccine effectiveness case-control study of sexually active persons aged 18-49 years who identified as MSM or transgender, collected during August 2022-July 2023. Odds of mpox associated with selected types of intimate and nonintimate close contact with a person with mpox were estimated. Among 457 case-patients and 1,030 control patients who met minimum data requirements, 150 (32.8%) case-patients and 57 (5.5%) control patients reported close contact with a person with mpox and were included in this analysis. Adjusted odds of mpox were 5.4 times as high among those who reported having condomless receptive anal sex with a person with mpox, compared with participants who reported close contact with a person with mpox and no condomless receptive anal sex with that person (OR = 5.4; p = 0.031). Although the mpox vaccine is highly effective, vaccination coverage remains low; a multifaceted approach to prevention remains important and should include vaccination promotion, safer sex practices, and increasing awareness that mpox continues to circulate.

This study examined coronavirus disease 2019 (COVID-19) prevention knowledge among community residents in Eastern Ethiopia to support public health interventions and vaccination coverage. A cross-sectional survey in August-September 2021 recruited 880 participants from households in a Health and Demographic Surveillance System (HDSS) in Harari and Oromia, Ethiopia. Participants were randomly selected and interviewed in person using tablets and a standardized questionnaire. Principal components analysis was used to create a score representing COVID-19 prevention knowledge. Quasi-Poisson regression was used to examine associations between demographic characteristics and COVID-19 prevention knowledge. The survey also assessed awareness of community/government COVID-19 prevention measures and healthcare services for under-5 children and pregnant women. The most cited COVID-19 prevention measures were handwashing with soap (91.5%) and wearing facemasks (89.2%); least mentioned were avoiding travel (22.2%) and wearing medical gloves (20.3%). Commonly recognized community/government measures included school closures (77.0%), avoiding gatherings (75.2%), and staying home (62.3%). Adjusted analyses demonstrated higher COVID-19 prevention knowledge among rural participants, those aged ≥65 years (reference: <25), with secondary education (reference: no education), with monthly income of ≥2,001 Birr (reference: 0–1,200), and were farmers, domestic/subsistence workers, or government employees (reference: unemployed). Knowledge was lower among households with ≥5 household members. Of households with under-5 children and pregnant women, 9.4% and 12.3% missed medical care visits since mid-March 2020 consequent to the pandemic. Public health interventions to reduce COVID-19 transmission rely on risk perception and knowledge. Understanding these factors can help Ethiopian authorities design effective health education programs to control community and household SARS-CoV-2 transmission. © The Author(s) 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.

BACKGROUND: The United States Preventive Services Task Force recommends annual alcohol screening and brief behavioral intervention (alcohol SBI) with general adult and pregnant populations. Implementation of alcohol SBI in primary care has encountered numerous barriers to adapting procedures and infrastructure to support its routine delivery. This collection of case studies describes the implementation strategies used by 4 academic health system teams that were funded by the Centers for Disease Control and Prevention to implement alcohol SBI within healthcare systems to prevent alcohol-exposed pregnancies. METHODS: We used constructs from the Framework for Reporting Adaptations and Modifications-Expanded (FRAME) to describe planned and unplanned adaptations to implementation strategies, and the SBIRT (Screening, Brief Intervention, and Referral to Treatment) Program Matrix to identify key questions, challenges, and recommendations for improving alcohol SBI implementation. Participating systems were 2 regional affiliates of a national reproductive healthcare organization, an integrated non-profit healthcare system, and an urban medical center and its affiliated network of community health centers. RESULTS: Planned adaptations included expanding the target population for brief interventions to include patients drinking at low levels who could become pregnant, modifying workflows and systems to support routine screening, and customizing training content and logistics. Unplanned adaptations included varying site recruitment and pre-implementation awareness-building strategies to enhance local receptivity of systems with decentralized management, and pivoting from in-person to virtual training during the COVID-19 pandemic. Fewer unplanned adaptations were observed for health systems with centralized management structures and practice teams that were fully engaged in implementation planning, training, roll-out, and problem-solving. CONCLUSIONS: Unplanned adaptations were observed across the 4 cases and emphasized the importance of flexible, adaptive designs when implementing evidence-based practice in dynamic settings. Participation of the health system in planning, including decisions to modify electronic health records and workflows, supported adapting to unplanned circumstances to achieve implementation goals.

BACKGROUND: The second phase of the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) transitioned from scaling up HIV prevention and treatment to promoting sustainability and capacity building for programs monitoring performance and evaluating key program indicators. We assessed the success of a monitoring and evaluation (M&E) curriculum designed to build capacity in three PEPFAR-supported countries. METHODS: We customized M&E trainings based on country-specific epidemic control priorities in Ethiopia, Guatemala, and Cameroon. The M&E curriculum included five modules and three evaluation activities to assess impact: (i) in-person pre-post confidence assessment surveys (CAS), (ii) in-person pre-post knowledge tests (PPKT), and (iii) electronic 6-12 months post-training translating knowledge into practice (TKP) surveys. Pre- and post-training results were compared within and across countries and triangulation with the qualitative data evaluated overall success. RESULTS: Among 188 participants attending M&E trainings, 154 (82 %) responded to CAS and 165 (88 %) participants from Ethiopia and Cameroon completed PPKT. Overall CAS scores between pre- and post-test improved [Score mean difference:1.5-1.9]. PPKT indicated statistically significant knowledge gained. One out of five TKP respondents provided direct application examples from the M&E training. CONCLUSION: While feedback was predominantly positive overall, revisions were recommended for three of the five modules. Developing a customizable and adaptable M&E curriculum may sustain countries' ability to monitor their progress towards epidemic control.

West Nile virus (WNV) is the most common cause of human arboviral disease in the contiguous United States, where only lineage 1 (L1) WNV had been found. In 2023, an immunocompetent patient was hospitalized in Nebraska with West Nile neuroinvasive disease and multisystem organ failure. Testing at the Centers for Disease Control and Prevention indicated an unusually high viral load and acute antibody response. Upon sequencing of serum and cerebrospinal fluid, we detected lineage 3 (L3) and L1 WNV genomes. L3 WNV had previously only been found in Central Europe in mosquitoes. The identification of L3 WNV in the United States and the observed clinical and laboratory features raise questions about the potential effect of L3 WNV on the transmission dynamics and pathogenicity of WNV infections. Determining the distribution and prevalence of L3 WNV in the United States and any public health and clinical implications is critical.

The Centers for Disease Control and Prevention's (CDC's) Global Rapid Response Team (GRRT) was created in 2015 to efficiently deploy multidisciplinary CDC experts outside the United States for public health emergencies. The COVID-19 pandemic dramatically increased the need for domestic public health responders. This study aimed to follow up on previously published data to describe the GRRT surge staffing model during the height of the COVID-19 response. We conducted descriptive analyses to assess GRRT deployment characteristics during April 1, 2019-March 31, 2022, and characteristics of responders rostered in 2021 and 2022. We analyzed data on response events, remote versus in-person work, and international versus domestic deployment location. We also examined the number of responders on call per month, language proficiency, and technical skills. During the study period, 1725 deployments were registered, accounting for 82 058 person-days deployed. Of all person-days deployed during the study period, 82% were related to COVID-19. Eighty-seven percent of all person-days deployed were domestic. Virtual deployments that were not in person accounted for 51% of deployments registered, yet these resulted in 67% of person-days deployed. The median deployment duration was 31 days. We found a median of 79 surge responders on call each month. Among 608 responders rostered in 2021 and 2022, 35% self-reported proficiency in a second language. Epidemiology was the most common technical skill (38%). GRRT transitioned to primarily remote, domestic deployments to support the COVID-19 pandemic response. The GRRT model demonstrates how response structure shifted to address the global health threat of a pandemic.

OBJECTIVES: This study aimed to estimate the incidence of asthma and assess the association between job exposure matrix (N-JEM) assigned occupational exposure, self-reported occupational exposure to vapour, gas, dust and fumes (VGDF), mould, damages from moisture and cold, and new-onset asthma. We also aimed to assess the corresponding population attributable fraction (PAF) for ever exposure to VGDF. DESIGN: Longitudinal population-based respiratory health study. SETTING: Responders from the baseline Telemark Study in south-eastern Norway were followed up from 2013 to 2018. PARTICIPANTS: 7120 participants, aged 16-55, were followed during a 5-year period. MAIN OUTCOME MEASURES: New-onset asthma and its association with self-reported occupational exposure to VGDF, data from the N-JEM and self-reported workplace conditions were assessed using logistic regression adjusted for gender, age, smoking and body mass index. The PAF was calculated using the PUNAF command in STATA. RESULTS: There were 266 (3.7%) cases of new-onset asthma and an incidence density of 7.5 cases per 1000 person-years. A statistically significant association was found for ever exposed to VGDF with an OR of 1.49 (95% CI 1.15 to 1.94), weekly OR 2.00 (95% CI 1.29 to 3.11) and daily OR 2.46 (95% CI 1.39 to 4.35) exposure to VGDF. The corresponding PAF for ever exposed to VGDF was 17% (95% CI 5.4% to 27.8%) and the risk of asthma onset increased with frequent VGDF exposure, indicating a possible exposure-response relationship (p=0.002 for trend). The N-JEM exposure group, accidental peak exposure to irritants had an increased risk of new-onset asthma, OR 2.43 (95% CI 1.21 to 4.90). A significant association was also found for self-reported exposure to visible damages due to moisture 1.51 (95% CI 1.08 to 2.11), visible and smell of mould 1.88 (95% CI 1.32 to 2.68), 1.55 (95% CI 1.12 to 2.16) and cold environment 1.41 (95% CI 1.07 to 1.86). CONCLUSION: Participants had elevated ORs for asthma associated with self-reported and N-JEM-assigned exposures. A PAF of 17% indicates that work-related asthma is still common. The possible exposure-response relationship suggests that reducing occupational VGDF exposure frequency could prevent the onset of asthma.

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.

INTRODUCTION: In March 2023, a Marburg Virus Disease (MVD) outbreak was declared in Kagera region, Northwestern Tanzania. This was the first MVD outbreak in the country. We describe the epidemiological characteristics of MVD cases and contacts. METHODS: The Ministry of Health activated an outbreak response team. Outbreak investigation methods were applied to cases identified through MVD standard case definitions and confirmed through reverse-transcriptase polymerase chain reaction (RT PCR). All identified case contacts were added into the contact listing form and followed up in-person daily for any signs or symptoms for 21 days. Data collected from various forms was managed and analyzed using Excel and QGIS software for mapping. RESULTS: A total of nine MVD cases were reported with eight laboratory-confirmed and one probable. Two of the reported cases were frontline healthcare workers and seven were family related members. Cases were children and adults between 1-59 years of age with a median age of 34 years. Six were males. Six cases died equivalent to a case fatality rate (CFR) of 66.7%. A total of 212 individuals were identified as contacts and two (2) became cases. The outbreak was localized in two geo-administrative wards (Maruku and Kanyangereko) of Bukoba District Council. CONCLUSION: Transmission during this outbreak occurred among family members and healthcare workers who provided care to the cases. The delay in detection aggravated the spread and possibly the consequent fatality but once confirmed the swift response stemmed further transmission containing the disease at the epicenter wards. The outbreak lasted for 72 days but as the origin is still unknown, further research is required to explore the source of this outbreak.

BACKGROUND: The Massachusetts Child Psychiatry Access Program for Moms and PRogram In Support of Moms are designed to help obstetric practices address perinatal depression. The PRogram in Support of Moms includes the statewide Massachusetts Child Psychiatry Access Program for Moms program, plus proactive implementation support. OBJECTIVE: The goal of this study was to understand the impact of these programs on perinatal generalized anxiety disorder and posttraumatic stress disorder symptoms among individuals screening positive for depression. STUDY DESIGN: We conducted a secondary analysis of 2017-2022 data from a cluster randomized controlled trial of Massachusetts Child Psychiatry Access Program for Moms vs PRogram In Support of Moms. We included participants completing a generalized anxiety disorder or posttraumatic stress disorder screen at baseline (n=254) with antenatal Edinburgh Postnatal Depression Scale scores ≥10. We assessed changes in generalized anxiety disorder and posttraumatic stress disorder symptoms from pregnancy (4-25 weeks of gestational age or 32-40 weeks of gestational age), 4-12 weeks postpartum, and 11-13 months postpartum. We conducted a difference-in-difference analysis to compare symptom change from pregnancy to postpartum. We used adjusted linear mixed models with repeated measures to examine the impact of the Massachusetts Child Psychiatry Access Program for Moms and PRogram In Support of Moms on changes in the Generalized Anxiety Disorder 7 and the Posttraumatic Stress Disorder Checklist. RESULTS: Mean Generalized Anxiety Disorder 7 scores decreased by 3.6 (Massachusetts Child Psychiatry Access Program for Moms) and 6.3 (PRogram In Support of Moms) points from pregnancy to 4-12 weeks postpartum. Mean Posttraumatic Stress Disorder Checklist scores decreased by 6.2 and 10.0 points, respectively, at 4-12 weeks postpartum among individuals scree ning positive on the Generalized Anxiety Disorder 7 (n=83) or Posttraumatic Stress Disorder Checklist (n=58) in pregnancy. Generalized Anxiety Disorder 7 and Posttraumatic Stress Disorder Checklist scores decreased among both groups at 11-13 months postpartum. These changes were clinically meaningful. PRogram In Support of Moms conferred a statistically significant greater decrease (2.7 points) on the Generalized Anxiety Disorder 7 than the Massachusetts Child Psychiatry Access Program for Moms at 4-12 weeks postpartum. No differences were found between the Massachusetts Child Psychiatry Access Program for Moms and PRogram In Support of Moms in Posttraumatic Stress Disorder Checklist or Generalized Anxiety Disorder 7 change at 11-13 months, although both were associated with a reduction in generalized anxiety disorder and posttraumatic stress disorder symptoms at 4-12 weeks and 11-13 months postpartum. CONCLUSION: Both the Massachusetts Child Psychiatry Access Program for Moms and PRogram In Support of Moms could help to improve symptoms for individuals experiencing co-occurring symptoms of depression, generalized anxiety disorder, or posttraumatic stress disorder. PRogram In Support of Moms may confer additional benefits in the early postpartum period, although this difference was not clinically significant.

BACKGROUND: The COVID-19 pandemic may have influenced partner-seeking and sexual behaviors of adults. METHODS: We examined cross-sectional survey data collected at the end of the first year (n = 1161) and second year (n = 1233) of the COVID-19 pandemic by the National Opinion Research Center's nationally representative, probability-based AmeriSpeak panel. Data were analyzed to (1) quantify behavioral changes across pandemic years, (2) examine changes of in-person dating prevalence during year 2, and (3) assess risk perception for acquiring COVID-19 or HIV/STIs through new partnerships during year 2. Weighted percentages were calculated for responses; univariate relationships between demographic characteristics and outcomes were assessed. RESULTS: Prevalence of new partners for dating remained stable across pandemic years (year 1: n = 1157 [10%]; year 2: n = 1225 [12%]). The prevalence of in-person sex with new partners was also stable (year 1: n = 1157 [7%], year 2: n = 1225 [6%]), marking a decline from a prepandemic estimate (2015-2016: 16%). Partner-seeking experiences varied by age and sexual identity in both years, and by race/ethnicity during year 2. Reports of in-person dating fluctuated throughout year 2, without clear relationship to viral variants. Respondents who met new partners in person during year 2 generally reported greater concern and preparedness for reducing risks associated with HIV/STIs than COVID-19. CONCLUSIONS: The prevalence of US adults seeking new partners for dating or sex remained stable across pandemic years. During future public health emergencies, public health officials are encouraged to offer guidance for reducing disease risks in partnerships, while emphasizing sexual health and providing tailored messaging for persons more susceptible to infection.

Hepatitis A is a vaccine-preventable disease that typically causes mild illness. Hepatitis A outbreaks associated with person-to-person transmission have been widespread in the United States since 2016. We used public-use US Multiple Cause of Death data to compare characteristics and listed comorbidities among decedents with hepatitis A-listed deaths during non-outbreak (2011-2015) and outbreak (2017-2021) periods and assessed the median age at death among decedents with and without hepatitis A-listed deaths during the outbreak period. From the non-outbreak period to the outbreak period, hepatitis A-listed deaths more than doubled (from 369 to 801), while the hepatitis A-listed age-adjusted mortality rate increased 150% (p < 0.001). When compared with the non-outbreak period, hepatitis A-listed decedents during the outbreak period were more frequently male, aged 18-49 years, non-Hispanic White, died in an inpatient setting, and had hepatitis A listed as their underlying cause of death. The median age at death for hepatitis A-listed decedents was significantly younger during the outbreak period overall and among females (62 and 66 years, respectively) compared with the non-outbreak period (64 and 72 years, respectively, p < 0.001). During the outbreak period, median age at death for hepatitis A-listed decedents was 14 years younger than decedents without hepatitis A listed. Compared with the general US population, decedents with hepatitis A listed on the death certificate died at younger ages during 2017-2021. Efforts are needed to improve hepatitis A vaccination coverage among adults recommended for hepatitis A vaccination to prevent additional premature hepatitis A deaths.

BACKGROUND: Fetal alcohol spectrum disorders (FASDs) are lifelong conditions that can occur in a person with prenatal alcohol exposure. Although studies using intensive, in-person assessments of children in selected communities have found higher estimates of children with FASDs than studies of healthcare claims data, claims-based studies provide more current information about individuals with recognized FASDs from diverse populations. We estimated the proportion of children with administratively reported FASDs in two large healthcare claims databases. METHODS: We analyzed Merative™ MarketScan® commercial and Medicaid claims databases, that include nationwide data from employer-sponsored health plans and from Medicaid programs in 8-10 states, respectively. For each database, we estimated the proportion of children aged 0-17 years with administratively reported FASDs, identified by one inpatient or two outpatient codes for prenatal alcohol exposure or fetal alcohol syndrome during the entire seven-year period from 2015 to 2021 and during each year. RESULTS: During 2015-2021, 1.2 per 10,000 commercially-insured and 6.1 per 10,000 Medicaid-insured children had an administratively reported FASD; estimates varied by sex, geography, and other available demographics. Among commercially-insured children, 0.5 per 10,000 in 2015 and 0.6 per 10,000 children in 2021 had an administratively reported FASD; among Medicaid-insured, 1.2 per 10,000 in 2015 and 2.1 per 10,000 children in 2021 had an administratively reported FASD. CONCLUSIONS: Although an underestimate of the true population of children with FASDs, patterns in administratively reported FASDs by demographics were consistent with previous studies. Healthcare claims studies can provide timely, ongoing information about children with recognized FASDs to complement in-persons studies.

BACKGROUND: A major update to the International Nuclear Workers Study (INWORKS) was undertaken to strengthen understanding of associations between low-dose exposure to penetrating forms of ionising radiation and mortality. Here, we report on associations between radiation dose and mortality due to haematological malignancies. METHODS: We assembled a cohort of 309 932 radiation-monitored workers (269 487 [87%] males and 40 445 [13%] females) employed for at least 1 year by a nuclear facility in France (60 697 workers), the UK (147 872 workers), and the USA (101 363 workers). Workers were individually monitored for external radiation exposure and followed-up from Jan 1, 1944, to Dec 31, 2016, accruing 10·72 million person-years of follow-up. Radiation-mortality associations were quantified in terms of the excess relative rate (ERR) per Gy of radiation dose to red bone marrow for leukaemia excluding chronic lymphocytic leukaemia (CLL), as well as subtypes of leukaemia, myelodysplastic syndromes, non-Hodgkin and Hodgkin lymphomas, and multiple myeloma. Estimates of association were obtained using Poisson regression methods. FINDINGS: The association between cumulative dose to red bone marrow, lagged 2 years, and leukaemia (excluding CLL) mortality was well described by a linear model (ERR per Gy 2·68, 90% CI 1·13 to 4·55, n=771) and was not modified by neutron exposure, internal contamination monitoring status, or period of hire. Positive associations were also observed for chronic myeloid leukaemia (9·57, 4·00 to 17·91, n=122) and myelodysplastic syndromes alone (3·19, 0·35 to 7·33, n=163) or combined with acute myeloid leukaemia (1·55, 0·05 to 3·42, n=598). No significant association was observed for acute lymphoblastic leukaemia (4·25, -4·19 to 19·32, n=49) or CLL (0·20, -1·81 to 2·21, n=242). A positive association was observed between radiation dose and multiple myeloma (1·62, 0·06 to 3·64, n=527) whereas minimal evidence of association was observed between radiation dose and non-Hodgkin lymphoma (0·27, -0·61 to 1·39, n=1146) or Hodgkin lymphoma (0·60, -3·64 to 4·83, n=122) mortality. INTERPRETATION: This study reports a positive association between protracted low dose exposure to ionising radiation and mortality due to some haematological malignancies. Given the relatively low doses typically accrued by workers in this study (16 mGy average cumulative red bone marrow dose) the radiation attributable absolute risk of leukaemia mortality in this population is low (one excess death in 10 000 workers over a 35-year period). These results can inform radiation protection standards and will provide input for discussions on the radiation protection system.
