Croup is a common illness in young children that causes a swelling of the larynx, or voice box, and trachea, or windpipe. Dr. Green, can you tell us more about croup?

Dr. Green
Certainly, Dr. Patel. The swelling caused by croup makes the airway below the vocal cords narrow, which can make breathing noisy and difficult. Croup can also cause a barking cough and a hoarse voice.

Children between three months old and five years old are more likely to get croup than older children. In older children, the windpipe is larger and swelling is less likely to cause noisy, difficult breathing.

It's possible for children to get croup any time of year, but it is most common in the fall and winter months.
