Pregnant women might be at increased risk for severe coronavirus disease 2019 (COVID-19) (1,2). The COVID-19-Associated Hospitalization Surveillance Network (COVID-NET) (3) collects data on hospitalized pregnant with laboratory-confirmed SARS-CoV-2, the virus that causes COVID-19; to date, such have been limited. During March 1-August 22, 2020, approximately one in four aged 15-49 years COVID-19 was pregnant. Among 598 COVID-19, 54.5% were asymptomatic admission. 272 who symptomatic hospital...
Antigen-based tests for SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), are inexpensive and can return results within 15 minutes (1). Antigen have received Food Drug Administration (FDA) Emergency Use Authorization (EUA) use in asymptomatic symptomatic persons first 5-12 days after symptom onset (2). These been used at U.S. colleges universities other congregate settings (e.g., nursing homes correctional detention facilities), where serial testing of might facilitate...
hospital admissions are subject to lag.
Each year, infections from major foodborne pathogens are responsible for an estimated 9.4 million illnesses, 56,000 hospitalizations, and 1,350 deaths in the United States (1). To evaluate progress toward prevention of enteric States, Foodborne Diseases Active Surveillance Network (FoodNet) conducts surveillance laboratory-diagnosed caused by eight transmitted commonly through food at 10 U.S. sites. During 2020-2021, FoodNet detected decreases many that were due to behavioral modifications,...
Abstract Background Real-time reverse transcription polymerase chain reaction (rRT-PCR) and antigen tests are important diagnostics for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Sensitivity of has been shown to be lower than that rRT-PCR; however, data evaluate epidemiologic characteristics affect test performance limited. Methods Paired mid-turbinate nasal swabs were collected from university students staff tested SARS-CoV-2 using both Quidel Sofia SARS Antigen...
Abstract Background Influenza virus and SARS-CoV-2 are significant causes of respiratory illness in children. Methods Influenza- COVID-19–associated hospitalizations among children <18 years old were analyzed from FluSurv-NET COVID-NET, 2 population-based surveillance systems with similar catchment areas methodology. The annual hospitalization rate per 100 000 during the ongoing COVID-19 pandemic (1 October 2020–30 September 2021) was compared influenza-associated rates 2017–2018...
Global temperatures are projected to rise by ≥2 °C the end of century, with expected impacts on infectious disease incidence. Establishing historic relationship between temperature and childhood diarrhea is important inform future vulnerability under climate change scenarios.We compiled a national dataset from Peruvian government data sources, including weekly surveillance records, annual administered doses rotavirus vaccination, piped water access estimates, daily estimates. We used...
Abstract Background Enteroviruses (EV)—a group of viruses including echoviruses (E) and coxsackieviruses (CV)—and parechoviruses (PeV) can cause a range symptoms, respiratory illness; hand, foot, mouth disease; acute flaccid myelitis; meningitis; sepsis. Neonates (persons < 1 month old) are at higher risk severe EV or PeV disease. We analyzed data from the National Enterovirus Surveillance System (NESS) to assess types outcomes neonatal infections reported during 2004–2022. Methods...
Background Cryptosporidium is a leading cause of moderate-to-severe diarrhea (MSD) in young children Africa. We examined factors associated with infection MSD cases enrolled at the rural western Kenya Global Enteric Multicenter Study (GEMS) site from 2008-2012. Methodology/Principal findings At health facility enrollment, stool samples were tested for enteric pathogens and data on clinical, environmental, behavioral characteristics collected. Each child's status was recorded 60-day...
On November 10, 2021, the Michigan Department of Health and Human Services (MDHHS) was notified a rapid increase in influenza A(H3N2) cases by University Service (UHS) at Ann Arbor. Because this outbreak represented some first substantial activity during COVID-19 pandemic, CDC, collaboration with university, MDHHS, local partners conducted an investigation to characterize help control outbreak. Beginning August 1, persons COVID-19-like* or influenza-like illness evaluated UHS received...
Project Vigilancia de Embarazadas con Zika (VEZ), an intensified surveillance of pregnant women with symptoms the virus disease (ZVD) in Colombia, aimed to evaluate relationship between ZVD during pregnancy and adverse pregnancy, birth, infant outcomes early childhood neurodevelopmental outcomes. During May–November 2016, three Colombian cities who were reported national system, or visiting participating clinics, enrolled VEZ. Data from maternal pediatric (up two years age) medical records...
We conducted a national impact evaluation of routine rotavirus vaccination on childhood diarrhea in Peru, accounting for potential modifying factors.We utilized dataset compiled from Peruvian governmental sources to fit negative binomial models investigating the vaccination, piped water access, sewerage access and poverty rate clinic visits children under 5 years old 194 provinces. considered interaction between these factors assess whether sanitation or modified association ongoing visits....
Abstract University settings have demonstrated potential for COVID-19 outbreaks, as they can combine congregate living, substantial social activity, and a young population predisposed to mild illness. Using genomic epidemiologic data, we describe outbreak at the of Wisconsin (UW)–Madison. During August – October 2020, 3,485 students tested positive, including 856/6,162 living in residence halls. Case counts began rising during move-in week on-campus (August 25-31, 2020), then rose rapidly...
Knowledge of the specific dynamics influenza introduction and spread in university settings is limited.Persons with acute respiratory illness symptoms received testing by molecular assay during October 6-November 23, 2022. Viral sequencing phylogenetic analysis were conducted on nasal swab samples from case-patients. Case-control a voluntary survey persons tested was used to identify factors associated influenza; logistic regression calculate odds ratios 95% CIs. A subset case-patients first...

Identifying severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections during peripartum hospitalizations is important to guide care, implement prevention measures, and understand infection burden.This cross-sectional analysis used electronic health record data from which pregnancies ended (peripartum hospitalizations) among a cohort of pregnant persons at 3 US integrated healthcare networks (sites 1-3). Maternal demographic, medical encounter, SARS-CoV-2 testing, pregnancy...
Chemical and microbiological drinking water contaminants pose risks to child health but are not often evaluated concurrently. At two consecutive visits 96 households in Piura, Peru, we collected samples, administered exposure questionnaires, infant stool samples. Standard methods were used quantify heavy metals/metalloids, pesticides, Escherichia coli concentrations Stool samples assayed for bacterial, viral, parasitic enteropathogens. The primary source was indoor piped 70 of (73%); 36...
Background: Knowledge of the specific dynamics influenza introduction and spread in university settings is limited.

Viral sequencing phylogenetic analysis were conducted on nasal swab samples from case-patients. Case-control a voluntary survey persons tested was used to identify factors associated influenza; logistic regression calculate odds ratios 95% CIs. A...
OPS 24: Drinking water contamination and children's health, Room 411, Floor 4, August 27, 2019, 10:30 AM - 12:00 PM Background: Peru has undergone several health infrastructure developments since 2005, including increased access to piped drinking national introduction of oral rotavirus vaccination. We examined whether these factors were associated with lower diarrhea rates in children under five. Methods: fit a negative binomial model investigating the impact vaccination on 195 Peruvian...
