Which condition most often causes a barky cough in children?

• A. Croup
• B. Epiglottitis
• C. Pneumonia
• D. Congestive heart failure

Answer: (A)

A barking cough in children is most commonly produced by croup. This condition involves inflammation and swelling of the larynx and the subglottic portion of the airway, which narrows the airway and triggers the distinctive seal-like, barking cough along with inspiratory stridor, especially in young kids around 6 months to 3 years. It’s usually viral in origin, often presenting with a preceding upper respiratory infection and symptoms that worsen at night.

Epiglottitis typically presents with a sudden, very ill-appearing child, high fever, drooling, muffled voice, and preference for sitting forward, rather than a barky cough. Pneumonia features fever, more focal or diffuse chest findings, and a productive cough rather than a barking cough. Congestive heart failure in children causes tachypnea and signs of fluid overload or poor perfusion, not a barking cough.
