Clinic in Clackamas County is latest measles exposure location

PORTLAND, Ore. — Oregon health officials have identified a new measles exposure location in Clackamas County and are urging anyone who may have been exposed to contact a health care provider immediately.

The Oregon Health Authority and Clackamas County public health officials said the latest exposure occurred at Providence Immediate Care – Happy Valley, located at 16180 SE Sunnyside Road, Suite 102, in Happy Valley.

According to officials, people may have been exposed to measles if they were at the clinic between 11:05 a.m. and 3:47 p.m. on Tuesday, May 12.

Anyone who was at the location during that timeframe is advised to contact a health care provider and inform them they may have been exposed to measles. Providers can help determine whether a person is immune based on vaccination history, age, or laboratory evidence of prior infection.

Health officials said measles spreads easily through the air when an infected person coughs or sneezes. Individuals with measles are contagious for four days before a rash appears and up to four days afterward. The virus can also remain in the air for as long as two hours after an infected person leaves an area.

Symptoms of measles generally begin seven to 21 days after exposure and commonly include fever, cough, runny nose, and red eyes. A rash typically develops afterward, beginning on the face and spreading across the body.

Officials warned that measles can lead to serious complications, including ear infections, pneumonia, diarrhea, and in rare cases, brain swelling. Young children, pregnant people, adults older than 20, and individuals with weakened immune systems are considered most at risk for severe illness.

The Oregon Health Authority said the measles, mumps, and rubella (MMR) vaccine remains highly effective, with two doses providing about 97% protection against the virus.

Public health officials also urged anyone experiencing measles symptoms not to arrive unannounced at a medical office or urgent care clinic. Instead, they should call ahead so providers can take precautions to prevent additional exposures in waiting rooms and other shared spaces.
