“Measles cases continue to occur in King County, which means we face an ongoing risk of outbreaks among people who don't have immunity," said Jeff Duchin, Health Officer for Public Health – Seattle & King County. "Measles vaccine is safe, effective, and offers excellent protection. If you aren't sure if you're up to date with the recommended doses of measles, mumps, and rubella vaccine (MMR), see your health care provider and get a dose of MMR if needed." 

Last week, the health department announced an infant and a teen in King County were diagnosed with measles after having "household contact" with people previously diagnosed with measles. 

Measles is highly contagious and causes fever, rash, cough, and watery eyes. Symptoms can begin seven to 21 days after exposure, and is contagious from about four days before the rash appears to four days after it ends. The virus can remain in the air for up to two hours.  

If you think you have contracted measles, notify a clinic or hospital before arriving for evaluation.
