Pertussis 101
What is Pertussis?
Pertussis or whooping cough is a very contagious respiratory illness caused by a bacteria.
Whooping cough can be even more severe for babies younger than 1 and people with other medical conditions.
What symptoms should I watch for?
At first, a person with whooping cough might seem like they have a cold. Early symptoms (1-2 weeks):
- Runny or stuffed
- Low-grade fever
- Mild, occassional cough
Later symptoms:
Coughing fits that usually last 1-6 weeks or even up to 10 weeks. Coughing fits can cause people to:
- Make a high-pitched whoop when they inhale after a coughing fit.
- Vomit during or after coughing fits
- Feeling very tired
- Difficulty sleeping
- Struggle to breathe
- Vomiting
Babies may not have a cough and may have apnea which is a pause in breathing. For some babies, whooping cough may seem like a common cold for the entire illness, not just at the beginning.
