Whooping cough, also known as pertussis, is highly contagious and spreads easily from person to person. An infected person is most contagious during the early stages of the illness, often before they even realize they have whooping cough. Here's how it typically spreads4:
- Airborne droplets: The bacteria that cause whooping cough are primarily spread through tiny droplets released into the air when an infected person coughs or sneezes
- Close contact: Being in close proximity to an infected person, especially in enclosed spaces, increases the risk of transmission
Without treatment, an infected person can be contagious for up to three weeks after the coughing fits begin.
To prevent the spread of whooping cough, it's important to practice good hygiene, such as covering your mouth and nose when coughing or sneezing, washing your hands frequently, and staying home when you're sick. Vaccination is a crucial preventive measure against whooping cough for yourself and others.
