Gov. Jay Inslee declared a state of emergency Friday statewide due to the measles outbreak that started in Clark County.

Clark County Public Health has confirmed 30 measles cases and nine suspected cases since Jan. 1, according to a Friday news release. The Clark County Council declared a public health emergency for the county Jan. 18.

“Measles is a highly contagious infectious disease that can be fatal in small children,” Inslee stated in a proclamation. “The existence of (31) confirmed cases in the state of Washington creates an extreme public health risk that may quickly spread to other counties.”

Public Health announced one new Clark County exposure location Friday: God Will Provide Church, 7321 N.E. 110th St., Vancouver, from 7 to 11 p.m. Jan. 18.

The Oregon Health Authority also on Friday confirmed a measles case in a Multnomah County, Ore., resident. The agency is working with Multnomah County and state agencies in Oregon and Washington to notify people of their potential exposure, and help them prevent exposing others should they become ill.
