what are the symptoms of the croup cough
Symptoms, which often include a runny nose and a brassy cough, develop about 2 to 6 days after being exposed to someone else with croup (incubation period). Signs and Symptoms of Croup One of the first distinctive features of croup is the abrupt or sudden onset of symptoms.
The symptoms of croup are caused by inflammation, swelling and the buildup of mucus in the larynx, trachea (windpipe) and bronchial tubes. Since younger infants and children have smaller airways, it makes sense that they are the ones most affected by croup.
