Croup is a common childhood illness that causes a bark like cough. It can also cause difficulty breathing which can be frightening for both you and your child.

Croup is caused by a virus which affects the airways including the voice box (larynx), windpipe (trachea) and lungs (the bronchi) causing them to swell and become narrower. 

Some children have croup two or more times in their childhood.

Please see Red-Amber-Green tables for advice on when and where to seek care for your child.
