Croup: Overview

Croup is an inflammation of the airways, usually caused by a viral infection. The hallmark symptom of croup is a “barking cough” but there are also other causes of barking cough (see Misdiagnosis of Croup). Croup is usually a mild and self-limiting infection, but in some cases it can be severe. Nasty complications need to be watched for, such as wheezing, shortness of breath, difficulty breathing, blueness, and other signs of breathing problems; if there are any such signs of breathing difficulty you need to contact your doctor or emergency care immediately.
