Croup is a common respiratory illness caused by a viral infection.
Croup can cause swelling of the upper airways, including the windpipe (trachea), voice box (larynx) and vocal cords. This swelling can lead to a hoarse voice, barky cough and sometimes difficulty breathing. Infections are common in babies and children up to 2 years of age because their airways are smaller, but older children can also get group. Croup is especially common in the fall and winter months, but children can get infected any time throughout the year.
