“Measles is highly contagious. If you don’t have immunity, you can get measles just by being in a room where a person with measles has been,” said Elysia Gonzales, Medical Epidemiologist for Public Health – Seattle & King County. “The best protection against measles is to get vaccinated. Two doses of measles, mumps and rubella (MMR) vaccine provides about 97% protection against getting infected by measles and that protection lasts a lifetime.”

What to do if you were in a location of potential measles exposure

Most people in our area have immunity to measles through vaccination, so the risk to the general public is low. However, anyone who was in the locations of potential exposure to measles around the times listed should:

  • Find out if you have been vaccinated for measles or have had measles previously. Make sure you are up-to-date with the recommended number of measles (MMR) vaccinations.
  • Call a healthcare provider promptly if you develop an illness with fever or with an unexplained rash. To avoid possibly spreading measles to others, do not go to a clinic or hospital without calling first to tell them you want to be evaluated for measles.

You can get vaccination or medication after exposure in some cases to prevent illness – check with your healthcare provider. This is especially important for people at high risk for measles complications.

If you were at the locations at the times listed above and are not immune to measles, the most likely time you would become sick would be between 5/18/2023 – 6/5/2023.
