Pertussis, a disease caused by infection with the Bordetella pertussis or Corynebacterium diphtheriae, is a contagious respiratory illness. The typical symptom is severe coughing, which presents as paroxysmal, rapid coughing fits. This coughing can lead to redness in the face and ears, a runny nose, tears, and bulging neck veins. If these coughing symptoms are prolonged, it is advisable to visit a hospital to check the pathogen in the secretions. Once the pathogen is confirmed, treatment can include oral or intravenous macrolide antibiotics to control the infection, along with symptomatic treatment. (Note: The use of medications should be under the guidance of a professional doctor.)
