Another contributing factor is the waning immunity provided by either infection or vaccination. Antibodies against pertussis do not last a life time, so adults who were either infected or vaccinated as children may have lost their immunity.

For this reason the CDC is recommending booster vaccines for teens and adults, especially health care workers and those exposed to young children.
