RSV Risk: Understanding RSV-Related Hospitalization of High-Risk Infants

Respiratory syncytial virus (RSV) bronchiolitis and RSV pneumonia are the leading causes of hospitalization of infants younger than 1 year of age in the United States. Preterm infants, born at 32 to 35 weeks gestational age or less, are particularly at high risk for severe RSV disease. Early recognition of the risk factors known to predispose to serious RSV lower respiratory tract infection is key to planning an effective RSV disease prevention strategy in high-risk infants.
