Anyone who visited three Providence Health facilities between Thursday, July 9, and Sunday, July 12, may have been exposed to measles, the Oregon Health Authority announced Tuesday, July 14.

The warning covers locations in Happy Valley, Oregon City, and Portland where Bethany, Cedar Mill, Oak Hills, and West Haven-Sylvan residents may have sought emergency or urgent care.

OHA and Multnomah and Clackamas county public health officials urged anyone present at the sites during five specific time windows to call their health care provider immediately.

Where and when

The exposure sites and times, according to OHA:

• Providence Immediate Care — Happy Valley, 16180 SE Sunnyside Road, Suite 102: 7:42 a.m. to 10:22 a.m., Thursday, July 9
• Providence Willamette Falls Medical Center emergency department, 1500 Division St., Oregon City: 12:18 a.m. to 5:56 a.m., Friday, July 10, and 10:04 a.m. to 2:57 p.m., Saturday, July 11
• Providence Portland Medical Center emergency department, 4805 NE Glisan St., Portland: 1:39 p.m. to 4:57 p.m., Saturday, July 11, and 7:32 p.m. to 9:46 p.m., Sunday, July 12

What to do

A health care provider can assess risk based on vaccination records, age, or lab evidence of prior infection, OHA said.

People experiencing measles symptoms should not show up unannounced at a clinic or emergency room. OHA spokesperson Jonathan Modie said people should "call your health care provider or urgent care center by telephone to create an entry plan to avoid exposing others in waiting rooms."

Symptoms begin seven to 21 days after exposure and often start with fever, cough, runny nose, and red eyes, followed by a rash that spreads from the face to the rest of the body.

Oregon's 2026 outbreak

Oregon has confirmed 27 measles cases so far in 2026, with one hospitalization, according to OHA. Of those 27 cases, 26 involved people who were unvaccinated or whose vaccination status was unknown.

One patient had received a single dose of the MMR vaccine.

The state reported just one measles case in all of 2025. The 2026 count is approaching the 31 infections reported in 2024, which was Oregon's highest annual total in more than three decades.

Tuesday's alert came after a quiet stretch. Oregon had not announced any public exposure locations since May 2026.

Measles basics

The virus spreads through the air when an infected person coughs or sneezes. Particles can linger for up to two hours after an infectious person leaves. People are contagious four days before a rash appears and four days after the rash appears.

Two doses of the MMR vaccine are about 97% effective at preventing infection. Measles can be especially dangerous for children younger than 5, adults older than 20, pregnant people, and those with weakened immune systems.

Resources

Families without a primary care provider can establish care at Multnomah County's seven primary care clinics or nine student health centers by calling 503-988-5558. Clackamas County residents can schedule an appointment with a Clackamas County Health Center. More information is available at OHA's measles page.
