Full Definition
Croup is a viral infection of the larynx, trachea, and bronchi that causes swelling and narrowing of the upper airways. It is characterized by a harsh, barking cough that resembles a seal's bark, along with inspiratory stridor. The condition typically affects children between 6 months and 6 years old, with peak incidence occurring in the second year of life. Most cases are mild and resolve with supportive care, though severe cases may require medical intervention with corticosteroids or epinephrine.
Usage
Usage note: Distinguish from other causes of stridor and respiratory distress in children.
