Pertussis (Whooping Cough)

Pertussis or "whooping cough" continues to be diagnosed in Washtenaw County. The Washtenaw County Health Department is working closely with all individuals diagnosed with pertussis and their contacts to make recommendations for treatment and prevention. Early identification of cases is very important.


Vaccination is recommended for all eligible persons. Parents and caregivers of infants too young to be vaccinated are especially encouraged to have the Tdap or pertussis-containing vaccine. No vaccine is 100% effective, and some fully-vaccinated persons may become ill. Vaccination and basic prevention of covering the mouth when coughing and washing hands offer the best protection against illness.


Antibiotics may be recommended if you have been exposed to pertussis. Antibiotics are not recommended without a known exposure or pertussis diagnosis. Please talk with your health care provider or a public health nurse at 734-544-6700 if you need more information.

Note: There were not enough pertussis cases in Washtenaw County to create reports for 2020, 2021, or 2022.
