Croup is a common respiratory illness caused by a viral infection in the airways. Accompanied by a barky cough and respiratory distress, this illness is most common in children from birth to 6 years of age, peaking at 2 years of age. This is a short, animated video about signs and symptoms of croup, and what to do if you are a parent or a family dealing with a child who has croup. This video was created through a collaboration between ECHO Research (University of Alberta), TREKK, and ARCHE (University of Alberta).
