Third measles case confirmed in WA, health officials warn of possible exposure

Health officials in Snohomish County, Washington, have confirmed a measles case involving an infant, marking the third case in the region this year. The infant is believed to have contracted the virus during recent international travel, prompting an investigation into potential exposure sites in Snohomish and King Counties. Locations where the child may have exposed others include Seattle-Tacoma International Airport and various medical facilities. While most of the population is vaccinated, officials urge individuals who may have been at risk to check their vaccination status and take appropriate action if symptoms develop. Symptoms of measles can manifest between April 3 and April 21, 2025, for those who are not immune.

Dr. James Lewis of the Snohomish County Health Department expressed concern for the affected child and highlighted the vulnerability of young, unvaccinated children. Health experts recommend that parents ensure their children receive the MMR vaccine on schedule to avoid future outbreaks. Public health officials are closely monitoring the situation to mitigate further cases and protect community health.
