Oregon health officials warn of measles exposure at Happy Valley clinic
HAPPY VALLEY, Ore. (KATU) — Health officials have identified a new measles exposure site in Happy Valley.
The Oregon Health Authority and Clackamas County public health officials said people may have been exposed at Providence Immediate Care – Happy Valley, 16180 S.E. Sunnyside Road, Suite 102, between 11:05 a.m. and 3:47 p.m. Tuesday, May 12.
Officials said anyone who was at the clinic during that time should notify a health care provider about the possible exposure. Providers can determine whether a person is immune to measles by reviewing vaccination records, age or laboratory evidence of a previous infection.
Health officials urged people to monitor for symptoms and seek medical advice if they believe they may have been exposed.
ABOUT MEASLES
Measles is a highly contagious respiratory virus that spreads through the air when an infected person breathes, speaks, coughs or sneezes. The virus can linger in the air for up to two hours and can infect up to 90% of unprotected close contacts. Complications can include pneumonia, brain inflammation and death.
Nationwide, measles cases have been rising since early 2025. Nearly 2,300 cases were reported last year, with most occurring among unvaccinated children.
Symptoms typically begin seven to 21 days after exposure and include cough, runny nose and conjunctivitis accompanied by a high fever. A rash usually follows, starting on the head or neck and spreading downward. People are contagious from four days before the rash appears until four days after.

HA advises health care providers to report suspected cases immediately and consider post-exposure treatment for exposed patients. The measles, mumps and rubella vaccine can be given within 72 hours of exposure. Immunoglobulin may be administered within six days.
For most people 6 months and older who are eligible for vaccination, receiving the MMR vaccine within 72 hours of exposure is recommended.
Anyone not protected against measles is at risk, according to OHA. The agency encourages residents to check their vaccination status and contact a health care provider with questions.
