A quickly escalating measles outbreak around Portland, Oregon, has led health officials in nearby Clark County, Washington, to declare a public health emergency as they warn that people infected with the highly contagious virus since the beginning of the year have visited schools and churches, a dentist’s office, an Amazon locker pickup station, a Costco, and an Ikea.
Someone with measles was at Concourse D of the Portland International Airport on Jan. 7, the county’s public health department advised. An infected person attended a Portland Trail Blazers home game on Jan. 11.
At the beginning of last week, there were only a handful of confirmed cases.
