PY - 2011 T2 - Rudolph's Pediatrics, 22e AB - Infants and preschool children experience 6 to 10 respiratory illnesses per year, and school-age children and adolescents experience 3 to 5 illnesses annually.1 Respiratory infections are predominantly viral infections that are classified into (1) upper respiratory tract infection (URI), meaning the common cold, rhinitis, pharyngitis, otitis media, and conjunctivitis, and (2) lower respiratory tract infection (LRI), namely croup, laryngitis, tracheobronchitis, bronchiolitis, and pneumonia. This section will focus primarily on LRIs occurring in children with viral infections including those associated with characteristic lower respiratory infection presentations, eg, respiratory syncytial virus as the primary cause of bronchiolitis, parainfluenza as the primary cause of croup, and influenza as a primary cause of febrile tracheobronchitis.
