Measles cases in Washington have reached 10 so far this year.
Most recently, two measles cases were recorded in King County last week, according to a news release from Public Health-Seattle and King County.
A child and an adult of the same household were confirmed to have the virus. Officials believe the two were exposed while hosting an international visitor who reported being ill. The child had previously received one dose of the MMR vaccine, while the adult’s vaccination status is unknown.
