Officials: 30 measles cases in western Washington outbreak

VANCOUVER, Wash. (AP) – Health officials say the number of confirmed cases of measles in western Washington has grown to 30, with nine more cases suspected.

Clark County Public Health said Friday that 29 of the cases are in southwest Washington and one confirmed case is in King County, which is home to Seattle.

The majority of the cases involve children younger than 10.

Officials say 26 of the patients were not vaccinated against the highly contagious disease and in four cases it’s unclear whether the person was vaccinated.
