Pertussis, the disease, can be cured with timely and proper treatment, so there's no need to fear. It's important to clear any concerns and understand this correctly. Pertussis is primarily an acute infectious respiratory disease caused by Bordetella pertussis or Corynebacterium diphtheriae. The main clinical approach is to prevent the disease by administering the DTP vaccine. Once infected, the disease is characterized by typical paroxysmal bouts of coughing, including spasmodic coughing, sometimes accompanied by a crowing inspiratory stridor, and in some cases, symptoms resembling a barking cough. It is called pertussis because the course of the disease is long, but there should be no excessive fear as it can be completely cured with prompt treatment.
