Whooping cough, also called pertussis, starts like a cold. After 1 to 2 weeks, those symptoms give way to intense bouts of coughing. This can make it hard to breathe. It might make you throw up.
Whooping cough can lead to complications that can be life-threatening, especially in babies. It may be milder in adults. Knowing what to look for can help you get diagnosed and start treatment sooner.
