Who Is Affected by Croup

Croup causes the airway to swell and narrow and makes you have a harsh, barking cough and trouble breathing. It usually develops a day or two after the start of an upper respiratory infection.

Croup most commonly occurs during the late fall and early winter in children 6 months to 36 months of age.1 Adults rarely get croup because their breathing passages are stronger and larger than children's.
