Bellevue expands measles response

Bellevue is widening its measles response after a King County infant with measles visited sites in the city while infectious. (kingcounty.gov) Public Health – Seattle & King County said on April 10 that the infant had been in Bellevue, northeast Seattle and on public transit, including Safeway at 1645 140th Ave Northeast, Supreme Dumplings at 14603 Northeast 20th Street and Link light rail Line 2. (kingcounty.gov) The county said the child was likely exposed during recent international travel, had not yet been vaccinated and is not linked to the two adult King County cases announced on April 1. (kingcounty.gov 1) (kingcounty.gov 2) Measles spreads through the air before the rash appears, and King County says the virus can remain in the air for up to two hours after an infectious person leaves. (kingcounty.gov 1) (kingcounty.gov 2) King County says most residents are protected through vaccination, but people who were at the listed exposure sites should check their measles, mumps and rubella vaccination status and call a provider if they develop fever or an unexplained rash. (kingcounty.gov) The county’s measles page lists three measles cases in King County residents in 2026 as of April 10. Washington state had 33 confirmed cases as of the Department of Health update posted April 6, including two King County residents at that point. (kingcounty.gov) (doh.wa.gov) State health officials say 27 of Washington’s 33 confirmed measles cases this year were in unvaccinated people, and King County says two doses of measles, mumps and rubella vaccine provide about 97% protection. (doh.wa.gov) (kingcounty.gov) For Bellevue residents, the immediate timeline is the symptom watch window tied to the April 3 and April 5 exposure sites: King County says people who were exposed and are not immune would most likely get sick between April 10 and April 29. (kingcounty.gov) King County’s Eastgate Public Health Center in Bellevue already provides health services in East King County, and the county’s measles guidance tells anyone seeking evaluation after exposure to call ahead instead of walking into a clinic or hospital unannounced. (kingcounty.gov 1) (kingcounty.gov 2) The city’s expanded response starts as Bellevue residents sort through exposure notices, vaccination records and travel plans ahead of spring break and summer trips.
