Whooping cough is an acute respiratory infectious disease caused by Bordetella pertussis infection, commonly seen in children, with children under five years old being the most susceptible. The main clinical symptoms include paroxysmal spasmodic coughing and a crowing, inspiratory whoop, with the cough being more pronounced at night. The symptoms of whooping cough are severe, but the physical signs are mild. During lung auscultation, no dry or moist rales can generally be heard, and imaging examinations are also normal. However, whooping cough may be complicated by bronchopneumonia, bronchiectasis, and other complications, in which case lung X-rays may show shadows, but these shadows will disappear after recovery from the treatment.
