Pertussis, also known as whooping cough, is a highly contagious respiratory disease caused by the Bordetella pertussis or Corynebacterium diphtheriae bacteria. After infection, paroxysmal coughing occurs, and in later stages, the frequency of coughing episodes decreases and the duration of symptoms shortens. The main treatment should involve the use of macrolide antibiotics to eliminate the pathogen. Additionally, it is advisable to drink plenty of water, rest adequately, measure body temperature twice daily, and avoid excessive fatigue. As long as function and symptoms gradually ease, it indicates the recovery phase is beginning, generally requiring about fifteen to twenty days for complete recovery.
