How is whooping cough spread?

Page last updated 12 May 2020

Whooping cough is typically spread from person to person through tiny droplets in the air containing the bacteria. These droplets are created by coughing or sneezing. You can also get infected from other forms of close contact with an infected person, like kissing or sharing food.

Symptoms of whooping cough generally appear between 7 and 10 days after infection, and infected people are most contagious up to about 2 weeks after the cough begins.
