A concerning situation has emerged in Missoula County, Montana, as public health officials are alerting the community about a potential measles exposure. On Saturday, November 22, 2025, an individual infected with measles visited Missoula, prompting the Missoula Public Health (MPH) to issue a public health advisory. But here's where it gets critical: While no confirmed cases have been identified in Missoula County yet, the potential for exposure is real. MPH has identified three public locations the infected person visited, raising the possibility of wider exposure.
Measles, a highly contagious virus, can linger in the air for up to two hours after an infected person leaves a space. This means that anyone who was at the following locations on November 22nd during the specified times should be vigilant:
- 11 a.m. – 2:30 p.m.: Missoula TJ Maxx
- 12 p.m. – 3:30 p.m.: Missoula Scheels
- 1 p.m. – 4 p.m.: Missoula Old Chicago
MPH emphasizes that the goal of this notification isn't to incite panic, but rather to empower individuals to understand their vaccination status and monitor for symptoms.
The symptoms of measles include:
- Fever
- Cough
- Runny nose
- Red eyes
- White spots inside the mouth
- A red rash that typically begins on the face and spreads to the rest of the body.
Symptoms can develop anywhere from seven to 14 days after exposure, but it's important to note that it could take up to 21 days for symptoms to appear. Therefore, individuals potentially exposed on November 22, 2025, should monitor themselves for symptoms through December 14, 2025.
Health officials strongly advise anyone experiencing symptoms to contact their healthcare provider before visiting the office. This allows for special arrangements to be made to evaluate the patient without putting others at risk.
Vaccination is the most effective way to prevent measles. The existing recommendations for the measles, mumps, and rubella (MMR) vaccine in the United States remain unchanged. Two doses of the MMR vaccine are an impressive 97% effective in preventing measles.
According to MPH, the majority of people in Missoula are vaccinated against measles.
This situation is particularly noteworthy because Montana is currently battling its first measles outbreak in 35 years.
