Most cases of bronchiolitis are caused by the respiratory syncytial virus (RSV). RSV is a common virus that infects just about every child by 2 years of age. Outbreaks of RSV infection occur every winter, and individuals can be reinfected, as previous infection does not appear to cause lasting immunity.
