Pertussis, also known as whooping cough, is an infectious respiratory disease caused by the infection of Bordetella pertussis or Bordetella parapertussis. Clinically, it is characterized by episodes of sudden, rapid coughing, a bark-like cough, and an inspiratory "crowing" sound. It is also advisable to check the sputum culture to confirm the cause of the disease. In terms of treatment, in addition to symptomatic treatment, macrolide antibiotics should be selected and administered for at least about half a month. Options include intravenous drips of erythromycin injection or azithromycin injection.
