Pertussis often starts with mild cold symptoms. Then it turns into severe coughing fits followed by gagging, vomiting or a "whoop" sound.
Babies with pertussis may eat poorly, turn blue or stop breathing. Newborns are most at risk. They can develop life-threatening complications—like difficulty breathing, pneumonia or convulsions—that require hospitalization.
Pertussis epidemics happen every few years. In 2012, Washington had an epidemic with almost 5,000 cases. Pierce County had 700 cases.

How can I protect myself and my family?
Getting vaccinated is the best way to prevent pertussis.
- Kids should be vaccinated at 2 months, 4 months, 6 months, 12-18 months, 4-6 years and 11 years.
- Unvaccinated adults should be vaccinated.
- Pregnant people should be vaccinated during each pregnancy (at 27-36 weeks gestation). Vaccine given during pregnancy protects the baby until they can be vaccinated at 2 months. This is very important because most babies who die of pertussis are only a few weeks old.
- People who care for babies under 1 year old (like childcare providers or grandparents) should be vaccinated.
