The Oregon Health Authority (OHA), alongside public health officials in Multnomah and Clackamas counties, has identified three Providence medical facilities where members of the public may have been exposed to measles. Health officials are urging anyone who visited these locations during specific time windows to contact their health care provider immediately to assess their risk.
Exposure Locations and Timelines
Public health officials have released a list of dates and times when the virus may have been present at the following locations:
- Providence Immediate Care—Happy Valley (16180 SE Sunnyside Road, Suite 102, Happy Valley): Thursday, July 9, between 7:42 a.m. and 10:22 a.m.
- Providence Willamette Falls Medical Center, emergency department (1500 Division St., Oregon City): Friday, July 10, between 12:18 a.m. and 5:56 a.m.
- Providence Willamette Falls Medical Center, emergency department (1500 Division St., Oregon City): Saturday, July 11, between 10:04 a.m. and 2:57 p.m.
- Providence Portland Medical Center, emergency department (4805 NE Glisan St., Portland): Saturday, July 11, between 1:39 p.m. and 4:57 p.m.
- Providence Portland Medical Center, emergency department (4805 NE Glisan St., Portland): Sunday, July 12, between 7:32 p.m. and 9:46 p.m.
Assessing Risk and Seeking Care
Individuals who were at these locations during the specified times should contact a medical provider to evaluate their risk based on their age, vaccination history, or laboratory evidence of prior infection. For those without a primary care provider, Multnomah County offers appointments at seven primary care clinics and nine student health centers for individuals ages 5–18; appointments can be made by calling 503-988-5558. Clackamas County residents may schedule appointments through local county health centers.
Officials emphasized that patients should not arrive at a medical facility unannounced. If an individual has a measles-like rash, or has been exposed within the last 21 days and is experiencing symptoms such as fever, cough, or red eyes, they must call their provider by telephone first. This allows the facility to create an entry plan and avoid exposing others in waiting areas.
Understanding Measles Transmission and Symptoms
Measles is a highly contagious respiratory virus that spreads through the air when an infected person breathes, speaks, coughs, or sneezes. The virus is capable of lingering in the air for up to two hours after an infectious person has departed. An infected individual is considered contagious starting four days before a rash appears and continuing for four days afterward.
Symptoms typically manifest seven to 21 days after exposure. The illness often begins with a fever, cough, runny nose, and red eyes, followed by a rash that starts on the face and spreads to the rest of the body. While most people recover, the virus can lead to serious complications, including ear infections, pneumonia, and, in rare instances, swelling of the brain. The disease is considered particularly dangerous for children younger than 5, adults older than 20, pregnant individuals, and those with weakened immune systems.
Vaccination and Recent Trends
Health authorities maintain that vaccination is the most effective protection against the virus, noting that two doses of the MMR vaccine are 97% effective. For those who are up to date on their vaccinations, the risk of severe disease remains very low.
According to state data for 2026, there have been 27 reported measles cases in Oregon, resulting in one hospitalization. Of those 27 cases, 26 individuals were unvaccinated or had an unknown vaccination status, while one patient had received a single dose of the MMR vaccine.
