Croup is a childhood condition that affects the windpipe (trachea), the airways to the lungs (the bronchi) and the voice box (larynx).
Symptoms of croup
A child can get croup at any time of the year, although the condition is more likely to occur during the late autumn and early winter months.
Causes of croup
Croup usually develops as the result a viral infection. The infection causes the larynx (voice box) to become swollen and the trachea (windpipe) to become blocked.
Diagnosing croup
A GP can diagnose croup by studying your child's symptoms, particularly the sound of their cough.
Treating croup
The treatment of croup depends on how severe the symptoms are. Most cases do not need treating as the condition usually gets better on its own.
Complications of croup
Complications that develop as a result of croup are rare, with less than 5% of children needing a hospital visit.
