Whooping cough (pertussis) is a highly contagious respiratory tract infection. In many people, it’s marked by a severe hacking cough followed by a high-pitched intake of breath that sounds like “whoop.”
Whooping cough spreads easily from person to person through the air. When a person with whooping cough sneezes or coughs, they release small particles with the bacteria in them. Other people can then breathe in the bacteria.
It usually takes 5 to 10 days for symptoms to appear after exposure to the bacteria that cause whooping cough. Sometimes symptoms don’t develop for as long as 3 weeks.
Whooping cough appears similar to a common cold early on. Healthcare providers often don’t suspect or diagnose it until more severe symptoms appear.
Early symptoms can last for 1 to 2 weeks and usually include:
- Runny or stuffed-up nose
- Low-grade fever (less than 100.4°F)
- Mild, occasional cough
One to 2 weeks after the first symptoms start, people may develop paroxysms, known as coughing fits. These coughing fits usually last 1 to 6 weeks but can last for up to 10 weeks. The cough generally gets worse and becomes more common as the illness continues.
