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 Respiratory syncytial virus (RSV) infection is a leading cause of hospitalization among infants. However, estimates of the RSV hospitalization burden have varied, and precision has been limited by the use of age strata grouped in blocks of 6 to ≥ 12 months. METHODS We analyzed data from a 5-year, prospective, population-based surveillance for(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)
OBJECTIVES To compare bone mineral density (BMD) among human immunodeficiency virus (HIV)-infected children with population norms and to determine predictors of BMD in HIV-infected children. METHODS Total body BMD was measured by dual energy x-ray absorptiometry in 37 HIV-infected children and nine sibling controls at baseline. Clinical, dietary and(More)
BACKGROUND Influenza rapid antigen detection (rapid tests) can provide timely identification of infection and aid in clinical decision-making. Although the interpretation of test results depends on test characteristics and influenza prevalence, this information is limited in routine clinical practice. OBJECTIVE We sought to assess the times at which rapid(More)
BACKGROUND Since 2006, we have conducted population-based surveillance for rotavirus disease in children seen in hospitals and emergency departments (EDs) in Monroe County, NY (Rochester), Hamilton County, OH (Cincinnati), and Davidson County, TN (Nashville). METHODS During the 2006 and 2007 rotavirus seasons, clinical information and stool specimens were(More)
BACKGROUND Controversy exists over whether or not Ureaplasma urealyticum colonization or infection of the respiratory tract contributes to the severity of chronic lung disease (CLD), a major cause of morbidity and mortality in preterm infants. OBJECTIVES To evaluate the efficacy and safety of prophylactic or therapeutic erythromycin in preventing chronic(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)
