Exposure locations in King County
New locations will be posted as they are identified.

Most people in our area have immunity to the 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 below should:

  • Find out if you have been vaccinated for measles or have had measles previously.
  • Call a healthcare provider promptly if you develop an illness with fever or illness with an unexplained rash. To avoid possibly spreading measles to other patients, do not go to a clinic or hospital without calling first to tell them you want to be evaluated for measles.

Measles symptoms could appear starting from seven days after the first exposure to twenty-one days after the last exposure. Rash is most likely to appear ten to twelve days after an exposure. More information about measles and measles vaccination: www.kingcounty.gov/measles

These times include the period when the person was at the location and two hours after. Measles virus can remain in the air for up to two hours after someone infectious with measles leaves the area. Anyone who was at the following locations during the times listed could have been exposed to measles (listings highlighted in orange indicate new exposure locations identified):
