Croup is an infection of the voice box (larynx) and windpipe (trachea). It is often mild and most children soon recover. A steroid medicine is usually prescribed to ease symptoms. In some cases severe breathing difficulties develop. A small number of children with croup are admitted to hospital, usually for a short time until symptoms ease.

Croup has a very characteristic barking cough that sounds like a dog or seal barking. If they are more unwell they may start to struggle to breathe or get noisy breathing.

Any child who appears to be struggling to breathe needs to be seen by a medical professional urgently.
