A measles outbreak has been reported in Missoula County, Montana, with a public health alert issued by Missoula Public Health (MPH). On November 22, 2025, an infected individual visited three public locations, posing a potential risk to those who may have been present at the same time.
The affected places and timeframes are as follows:
- 11 a.m. to 2:30 p.m.: Missoula TJ Maxx
- 12 p.m. to 3:30 p.m.: Missoula Scheels
- 1 p.m. to 4 p.m.: Missoula Old Chicago
MPH emphasizes that this notification aims to inform and educate the public, not to induce panic. They urge individuals who visited these locations during the specified times to check their vaccination status and monitor for symptoms of measles, which can include fever, cough, runny nose, red eyes, white spots in the mouth, and a red rash starting on the face and spreading downward.
Symptoms typically appear within seven to 14 days after exposure but can take up to 21 days to manifest. Given the incubation period, MPH advises that individuals who may have been exposed should monitor for symptoms until December 14, 2025. If symptoms arise, they are encouraged to contact their healthcare provider in advance and seek evaluation in a manner that ensures the safety of others.
Measles prevention is primarily achieved through vaccination. The MMR vaccine, which protects against measles, mumps, and rubella, remains a recommended two-dose regimen in the United States, offering 97% effectiveness. MPH reassures that most residents in Missoula are already vaccinated against measles.
This outbreak marks the first measles case in Montana in 35 years, and health officials are actively working to contain it. The public is encouraged to stay informed and take appropriate measures to protect themselves and their communities.
