Bronchiolitis in Infants and Children.

Bronchiolitis is among the most common illnesses in infants and children, and is the most common cause for hospitalization in infants in the U.S. This illness can be caused by many viruses, most commonly respiratory syncytial virus. It is diagnosed clinically by history and physical exam findings, with a narrow role for ancillary testing. Management is supportive, with medications demonstrating limited utility in multiple studies. Preventive measures include hand hygiene, breastfeeding, avoiding tobacco smoke exposure, and isolation precautions for hospitalized patients. Palivizumab prophylaxis is recommended for infants with qualifying high risk conditions. Recent evidence-based clinical practice guidelines have been published by the American Academy of Pediatrics to guide diagnosis, treatment, and prevention of bronchiolitis.
