OREGON CITY, Ore. (KATU) — A new measles exposure site has been confirmed at a health care facility in Oregon City, the Oregon Health Authority (OHA) announced.
Officials said the potential exposure occurred at Legacy GoHealth, located at 1900 McLoughlin Blvd., Suite 67, during two time periods: from 9:09 a.m. to 12:22 p.m. Friday, April 10, and from 1:12 p.m. to 3:48 p.m. Saturday, April 11.
Anyone who was at the clinic during those times should immediately contact a health care provider and report the possible exposure, health officials said. Providers can determine whether a person is immune to measles based on vaccination records, age or laboratory evidence of prior infection.
Officials advised the public to visit the Oregon Health Authority’s measles website for the most up-to-date list of exposure locations.
Earlier on Tuesday, OHA identified Centennial Middle School as a measles exposure site.
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.
OHA 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.
