On May 12, 2019, Tacoma-Pierce County Health Department announced a Pierce County man in his 40s was diagnosed with measles.

We investigate infectious diseases as part of our foundational public health services. We learn which public places patients visited while infected, and work to notify those who were potentially exposed. In some cases, that means contacting hundreds of people.

In this case, the patient had been to Sea-Tac Airport and an after-hours meeting at Orting High School. On May 15, we confirmed one new case in Pierce County. We also learned of new cases in King and Snohomish counties.

Two confirmed cases
