Clark County Public Health has identified 30 confirmed cases of measles and nine suspected cases in Washington as of Friday.
Twenty-six of the 30 confirmed cases are people who had not received the measles vaccine. The remaining four cases' vaccination statuses are unverified.
Also on Friday, Oregon confirmed its first case, according to the Oregon Health Authority. The exposure happened in Multnomah County.
Washington Gov. Jay Inslee declared a state of emergency Friday in response to the outbreak. That directs state agencies and departments to utilize all available resources to assist affected areas.
With the news of those additional cases, there is also an addition exposure site — the God Will Provide Church at 7321 N.E. 110th St. in Vancouver. That exposure window was Friday, Jan. 18, from 7 p.m. to 11 p.m. The Oregon Health Authority said people may have also been exposed at Legacy GoHealth in Gresham, Fred Meyer in Wood Village, and Walgreens Pharmacy or the Family Medical Center in Troutdale.
A full list of Washington exposure sites is available on Clark County Public Health's website, and in Oregon people can visit Multnomah County's website for more information.
Clark County Public Health is encouraging anyone who has been exposed at an identified location with measles symptoms to call their health care provider before visiting a medical office in-person in order to limit causing further exposure.
