Croup

Croup is a condition caused by a viral infection. The virus leads to swelling of the voice box (larynx) and windpipe (trachea). This swelling makes the airway narrower, so it is harder to breathe. Children with croup develop a harsh, barking cough and may make a noisy, high-pitched sound when they breathe in (stridor). Croup mostly affects children between six months and five years old, but it can affect older children. Some children get croup several times. Croup can get worse quickly. If your child is having problems breathing, seek urgent medical attention.
