Croup. A common cause of airway obstruction in children.

Although viral croup is usually a self-limiting disease, its signs and symptoms are distressing enough to make parents seek immediate medical advice. This is fortunate because a much more serious disorder may be present. Indeed, morbidity requiring hospitalization may occur, as may a true emergency. Drs Thomsen and Edmonds discuss the epidemiology and current management of croup and related conditions.
