This pamphlet explains what croup is, how it is spread, what symptoms it causes and what to watch for if your child has the virus. A list of symptoms that require you to take your child to the Emergency Department is provided. The French version of this pamphlet 2191, "Croup (diphtérie laryngienne," is also available.
Croup is an inflammation of the larynx (voice box), trachea (windpipe), and large airways occurring in young children. The illness may begin with a runny nose, followed several days later by a harsh, barky (seal-like) cough, and hoarse voice. As the windpipe below the voice box narrows, noisy breathing (stridor) occurs as the child breathes in. Symptoms of croup often start suddenly during the night when the child awakens with a cough. Fever frequently is present.
Hypersecretory asthma is a term used to describe a group of children with asthma who don’t have the typical features of asthma that we see in other children. Children with hypersecretory asthma have a loose, wet sounding, or congested cough rather than the usual dry cough seen in most children with asthma. Wheezing is not a main symptom; in fact, some do not wheeze at all. Fever (often high) and decreased energy and appetite are often associated with flare-ups.
