The state health department has identified another case of measles, this time in Park County.
The vaccinated adult had “extensive exposure" to the virus while abroad and developed a mild case that didn’t require hospitalization, per the health department.
Members of the public may have been exposed to the park county case at two places earlier this month:
- Albertsons, 1825 17th St., Cody, WY 82414
- December 15, 2025, 1:30 PM – 4:00 PM
- December 17, 2025, 2:30 PM – 5:00 PM
- Walmart, 321 Yellowstone Ave., Cody, WY 82414
- December 18, 2025, 2:30 PM – 5:00 PM
It’s rare for immunized people to develop a measles infection. It typically results in a milder illness. Of the 1,958 measles cases reported in the country to date this year, 93% have been unvaccinated, 3% have received one dose of the measles, mumps and rubella (MMR) vaccine and 4% have received two doses, according to information provided by the health department in a press release.
Earlier last week, the health department announced five new cases in unvaccinated adults and children in Fremont County. The five spread it among each other after contracting it out of state.
Measles is a highly contagious virus that can cause serious illness, including pneumonia, encephalitis, hospitalization and death. The MMR vaccine provides highly effective, long-lasting protection against infection, according to the state health department.
The department recommends all residents ensure themselves and their children are up-to-date on their vaccinations, which are widely available through health providers’ offices, pharmacies and public health nursing offices.
