Acute bronchiolitis: Influence of viral co-infection in infants hospitalized over 12 consecutive epidemic seasons
Bronchiolitis is the first lower respiratory tract viral infection manifesting in infants younger than 12 months of age. Our aim was to evaluate clinical and serological differences in infants with bronchiolitis from a single or from multiple viruses. Our secondary aim was to investigate differences in recurrent wheezing episodes after 12-24-36 months of follow-up. We reviewed the clinical records for 486 full-term infants hospitalized for bronchiolitis with at least one virus detected in the nasopharyngeal aspirate.
