Can you get whooping cough multiple times?

Answer 1

Yes, it's possible. The immunity one gets from infection with Bordetella pertussis, the causative agent for whooping cough, varies widely from person to person. Furthermore, immunity wanes over the years.

Also, Bordetella parapertussis, mycoplasma and certain adenoviruses can produce an illness similar to whooping cough. So a person may think that he or she has had the illness more than once.
