WA Health: Significant increase in reported cases of pertussis (whooping cough)

WHATCOM COUNTY, Wash. — The Washington State Department of Health reported on November 7th that, as of November 2nd, 1,193 cases of pertussis, commonly known as whooping cough, had been reported across Washington state. At the same time last year, 51 cases had been reported.

Cases have been reported in 31 Washington counties including 37 cases in Whatcom County.

Whooping cough is a highly contagious bacterial infection that may begin with common cold symptoms such as runny nose but can lead to severe coughing fits that can last for weeks or even months. Visit the CDC’s website for more information on symptoms. If you believe you have whooping cough, contact your healthcare provider.

As of November 2, 28 people have been hospitalized, including 12 infants under the age of one. Infants, particularly those under one year old, are at the highest risk for severe illness and death. Some infants may not show typical coughing symptoms but can experience dangerous pauses in their breathing.

“The surge in pertussis cases is a stark reminder of how critical vaccinations are in protecting our most vulnerable, especially infants for whom it can be life threatening,” said Tao Sheng Kwan-Gett, M.D., pediatrician and Chief Science Officer at DOH. “To protect babies from whooping cough, people of all ages should get up to date on pertussis vaccination, and anyone with symptoms should see a health care provider to see if testing and antibiotic treatment are needed.”

Vaccination is the most effective way to prevent severe illness from whooping cough. DOH urges all families and caregivers who interact with infants and young children to ensure they’re up to date on their whooping cough vaccinations. Pregnant people are strongly encouraged to get the Tdap vaccine between 27 and 36 weeks of pregnancy, which helps protect their newborns until they’re old enough to start the whooping cough vaccination series at two months. Young children need four doses of pertussis vaccine before 18 months of age for best protection.
