Pertussis-like cough usually resolves in about 3 months at the earliest, depending on the individual and the specific condition. The etiology of whooping cough-like syndrome is not clear. The main clinical manifestations are paroxysmal, irritating, persistent, spasmodic coughs, with a high incidence in the winter and spring. Patients may develop a spasmodic cough typical of whooping cough, or in severe cases, a typical cockle-like roar, which is often clinically confused with pertussis. In the absence of other complications, most cases of pertussis syndrome can be recovered in as little as 3 months or so. Recovery time varies individually, as each patient has a different physical profile and responds differently to drug sensitivity. In case of serious complications, such as pneumonia, pertussis encephalopathy, cardiovascular system disorders, malnutrition, etc., the recovery time can be extended accordingly. In addition, pertussis-like cough is contagious, i.e., it is transmitted through droplets, and patients’ families are advised to take protective measures.
