Measles Alert: Exposure Sites Multiply Across Portland Metro

Oregon health authorities on Thursday added more public locations in the Portland metropolitan area where people may have been exposed to measles last week. The Oregon Health Authority said it is working with the Clackamas and Multnomah County public health departments on the updated list of potential exposure sites.

Officials identified Lark Café in West Linn as a possible exposure location on March 27. They also listed Pho.Com in Gresham on March 25, and a Safeway in Portland spanning multiple dates from March 26 to March 29. Health authorities said the sites reflect where an infectious person may have been present during the specified times.

The new locations follow an earlier public notice issued this week about potential exposure at Providence Portland Medical Center’s emergency room waiting room. Officials said the newly listed sites are not confirmed to be connected to additional confirmed cases. Oregon has recorded 11 measles cases this year, and officials said most have involved unvaccinated individuals.

Health authorities noted that Oregon typically updates its statewide measles case count on Fridays. They also reiterated that measles spreads through the air and is highly contagious. Officials said symptoms generally emerge 7 to 21 days after exposure and can include fever, cough, runny nose, red eyes, and a rash.

Officials advised anyone who visited the listed locations during the specified windows to contact a medical provider promptly. The guidance is intended to help people confirm immunity status and reduce the risk of further transmission. Health authorities emphasized that timely outreach to clinicians can support appropriate next steps for individuals who may have been exposed.

Nationally, the Centers for Disease Control and Prevention reported more than 1,570 measles cases in 2026, compared with approximately 2,300 across all of 2025. The CDC figures indicate an upward trend in reported cases. Oregon officials’ updated exposure list comes as public health agencies continue to use location-based alerts to inform the public and limit spread when potential exposures occur in high-traffic settings such as restaurants, grocery stores, and hospital waiting areas.
