Whooping cough is an acute respiratory infectious disease caused by Bordetella pertussis infection, commonly seen in children. The main symptoms are paroxysmal spasmodic coughing, a crowing inspiratory noise, with coughing occurring both during the day and at night, more significantly at night. The main reasons are as follows: first, the dry indoor air causes irritation. Second, during the night, the mucus secreted by the bronchial mucosa cannot be expelled from the body, which stimulates the bronchial nerves and triggers worsening cough symptoms. Coughing can also cause redness of the face and ears, runny nose, nausea, and vomiting.
