Frequently asked questions
Why is whooping cough dangerous for babies?
Young babies may not cough in the typical way and can instead stop breathing. It can be life-threatening in infants, which is why vaccination in pregnancy and infancy is so important.
How long does whooping cough last?
The cough can last many weeks (it is sometimes called the "hundred-day cough"), though antibiotics started early and vaccination reduce severity and spread.
Can adults get whooping cough?
Yes. Immunity fades over time, so adults can catch it and pass it to vulnerable babies — often without realising what it is.
