1 doctor agrees

In brief: 1-2 weeks

The incubation period for pertussis about 7-10 days, with a range of 4-21days.
If you know your baby was exposed, call your baby's doctor. There are medicines to help prevent disease after a known exposure.

In brief: 1/2 - 3 weeks

A baby exposed to pertussis needs to be evaluated by the doctor. The incubation period (time from exposure to onset of ill symptoms) is from few days up to 3 weeks, in the majority of cases.
