If whooping cough has been cured, generally, it won’t infect a person again. However, clinically, a small number of patients might get infected again due to weak immunity, though such cases are relatively rare.

Whooping cough is caused by an infection with Bordetella pertussis and is an acute respiratory infectious disease. The source of infection in whooping cough is the patient themselves, and the disease can spread through airborne droplets. Most people who contract this disease will develop corresponding antibodies, so generally, they will not get infected again after recovery.

However, some patients with weak constitutions and low immunity might not develop sufficient antibodies after the initial infection, which can potentially lead to a reinfection.
