How to determine recovery from whooping cough

In general, patients with pertussis experience severe coughing. If a patient notices that their cough has diminished or even disappeared, this may indicate that the disease has resolved. For individuals with strong immunity and mild illness, recovery typically occurs within one month. However, to accurately confirm recovery, it is still recommended to undergo a thorough medical evaluation at a hospital and determine the status based on examination results.

Pertussis is an acute respiratory infectious disease caused by infection with *Bordetella pertussis*. It commonly affects children, although elderly individuals with weakened immune systems are also susceptible. The main clinical features include paroxysmal spasmodic coughing accompanied by a prolonged "whooping" sound during inhalation, which is particularly prominent at night. Laboratory tests often show a marked increase in peripheral white blood cell count, lymphocyte count, and lymphocyte percentage.

Clinically, pertussis usually progresses through three stages: catarrhal stage, paroxysmal stage, and convalescent stage. Entry into the convalescent stage indicates gradual improvement of the disease. At this point, episodes of stimulatory, spasmodic coughing gradually decrease and may eventually disappear noticeably. However, treatment should not be discontinued at this stage; symptomatic treatments such as antispasmodic and anti-asthmatic therapies should continue to further control symptoms and prevent relapse.

Due to the risk of recurrence, it is advisable to undergo a comprehensive medical check-up at the hospital after completing pertussis treatment to monitor for possible relapse.
