Changing Epidemiology of Life-Threatening Upper Airway Infections: The Reemergence of Bacterial Tracheitis

Abstract

Immunization against Haemophilus influenza type b and widespread use of corticosteroids for the treatment of viral croup have changed the epidemiology of acute infectious upper airway disease. As potentially life-threatening infections, viral croup and epiglottitis have been eclipsed by bacterial tracheitis. In this series, bacterial tracheitis was 3 times more likely to have caused respiratory failure than viral croup and epiglottitis combined. Bacterial tracheitis should be considered in children who present with acute life-threatening upper airway infection.
