BACKGROUND The primary role of respiratory syncytial virus (RSV) in causing infant hospitalizations is well recognized, but the total burden of RSV infection among young children remains poorly defined. METHODS We conducted prospective, population-based surveillance of acute respiratory infections among children under 5 years of age in three U.S.(More)
BACKGROUND The disease burden of influenza infection among children is not well established. We conducted a population-based surveillance of medical visits associated with laboratory-confirmed influenza. METHODS Eligible children were younger than five years of age, resided in three U.S. counties, and had a medical visit for an acute respiratory tract(More)
IMPORTANCE Newborn screening for severe combined immunodeficiency (SCID) using assays to detect T-cell receptor excision circles (TRECs) began in Wisconsin in 2008, and SCID was added to the national recommended uniform panel for newborn screened disorders in 2010. Currently 23 states, the District of Columbia, and the Navajo Nation conduct population-wide(More)
BACKGROUND Although recent studies have identified new group C human rhinoviruses (HRVCs), their spectrum of pediatric disease is unknown. OBJECTIVE We sought to determine the presentation and burden of disease caused by HRVCs among young hospitalized children. METHODS We conducted prospective population-based surveillance in 2 US counties among(More)
Recent studies have associated human metapneu-movirus (HMPV) infection in children with respiratory disease of similar severity as respiratory syncytial virus (RSV) infection. We studied 668 banked swab specimens (one per admission) collected from a population-based, prospective study of acute respiratory illness among inpatient children from two U.S.(More)
BACKGROUND Cases of rotavirus-associated acute gastroenteritis have declined since the introduction of rotavirus vaccines, but the burden of norovirus-associated acute gastroenteritis in children remains to be assessed. METHODS We conducted active surveillance for laboratory-confirmed cases of norovirus among children younger than 5 years of age with(More)
OBJECTIVE Respiratory syncytial virus (RSV), influenza virus, and parainfluenza viruses (PIV) cause significant morbidity in young children. Although only influenza virus infection and illness is currently vaccine-preventable, vaccines are under development for RSV and PIV. We established a prospective, active population-based surveillance network to(More)
BACKGROUND Routine rotavirus vaccination of US infants began in 2006. We conducted active, population-based surveillance for rotavirus gastroenteritis hospitalizations in 3 US counties to assess vaccine impact. METHODS Children <36 months old hospitalized with diarrhea and/or vomiting were enrolled from January through June each year during the period(More)
BACKGROUND We assessed vaccine effectiveness (VE) for RotaTeq (RV5; 3 doses) and Rotarix (RV1; 2 doses) at reducing rotavirus acute gastroenteritis (AGE) inpatient and emergency department (ED) visits in US children. METHODS We enrolled children <5 years of age hospitalized or visiting the ED with AGE symptoms from November 2009-June 2010 and from(More)
There is only limited knowledge on the burden of disease due to both new (HCoV-NL63 and HKU-1) and previously discovered coronaviruses (OC43 and 229E) in children. Respiratory specimens and clinical data were prospectively collected in an active, population-based surveillance study over a 2-year period from children aged <5 years hospitalized with acute(More)
