Measles Outbreak Expands: WinCo in Gresham Added as Exposure Site

Gresham, Oregon - March 13th, 2026 - The Oregon Health Authority (OHA) today announced the addition of a WinCo Foods grocery store in Gresham to the growing list of locations potentially exposing individuals to measles. This development signals a concerning expansion of the recent outbreak affecting the Portland metropolitan area and reignites the debate around vaccination rates and public health preparedness.

The WinCo Foods store located at 1520 NE Halsey St. in Gresham has been identified as a potential exposure site for individuals who visited on March 6th or 7th, 2026. The OHA is urging anyone present at the store during those dates to actively monitor themselves for symptoms of measles, which include a high fever, persistent cough, runny nose, and a characteristic rash that typically appears a few days after initial symptoms. Individuals experiencing these symptoms are strongly advised to contact their healthcare provider before seeking medical attention, to allow for appropriate precautions to be taken and prevent further transmission.

This latest addition joins a string of previously identified exposure sites across the Portland region, painting a picture of a steadily increasing outbreak. While the OHA has not released a comprehensive list of all locations, the repeated identification of public spaces - including potentially schools, healthcare facilities, and now grocery stores - suggests a significant level of community spread. The authority is working to trace contacts and contain the virus, but the highly contagious nature of measles presents a formidable challenge.

A Return of a Preventable Disease

Measles was declared eliminated in the United States in 2000. However, imported cases, often from travelers returning from countries where measles remains common, can spark outbreaks, especially in communities with low vaccination rates. The current situation in Oregon is deeply concerning because it demonstrates the vulnerability of even highly developed regions to preventable diseases when vaccination coverage declines. Experts point to a confluence of factors contributing to this trend, including misinformation regarding vaccine safety, decreased access to healthcare, and waning public trust in public health institutions.

The OHA emphasizes that measles is not merely a childhood illness. While generally more severe in young children and infants, measles can also cause serious complications in adults, including pneumonia, encephalitis (inflammation of the brain), and even death. Individuals with weakened immune systems are particularly vulnerable. The virus spreads through respiratory droplets produced when an infected person coughs or sneezes, making it exceptionally easy to transmit in crowded indoor environments like grocery stores.

Vaccination: The Key to Protection

Public health officials are unequivocal in their message: vaccination remains the most effective way to prevent measles and protect communities. The Centers for Disease Control and Prevention (CDC) recommends that children receive two doses of the MMR (Measles, Mumps, and Rubella) vaccine, with the first dose administered between 12 and 15 months of age and the second dose between 4 and 6 years of age. Adults born in 1957 or later who have not had measles or been vaccinated are also advised to receive the MMR vaccine.

"We are deeply concerned about the rising number of measles cases and the potential for wider spread," stated Dr. Emily Carter, State Epidemiologist for the Oregon Health Authority. "Vaccination is a safe and effective way to protect yourself and your community. We urge all Oregonians to review their vaccination records and ensure they are up-to-date. It's also crucial to stay home if you are feeling sick to prevent exposing others."

The OHA website ([ https://www.oregon.gov/oha/ph/diseasesconditions/communicable-diseases/measles ] - link verified as of March 13, 2026) provides comprehensive information about measles, vaccination, and current outbreak updates. Residents are encouraged to consult this resource for the latest guidance and information.

The situation in Gresham, and across the Portland metro area, serves as a stark reminder of the importance of maintaining high vaccination rates to protect public health and prevent the resurgence of preventable diseases. The OHA is continuing its surveillance and response efforts, but ultimately, the success of containing this outbreak hinges on the collective responsibility of Oregonians to prioritize vaccination and public health safety.
