The Central Michigan District Health Department (CMDHD) has confirmed a measles case in Osceola County.

The health department is working with the Michigan Department of Health and Human Services to investigate the case. Public exposure sites are being evaluated and will be shared if identified.

So far in 2025, more than 1,300 measles cases have been reported across 40 states. About 1 in 5 people with measles have been hospitalized.

“Measles is highly contagious and spreads easily through the air,” said Steve Hall, CMDHD health officer. “Anyone unvaccinated is at higher risk of illness if exposed.”

Up to 9 out of 10 unvaccinated people exposed to measles will become infected. Symptoms, including high fever (may exceed 104°F), cough, runny nose, red and watery eyes, a raised red rash starting on the face and spreading to the body, or tiny white spots in the mouth, typically appear 7 to 14 days after exposure but can take up to 21 days. If you experience these symptoms, contact your health care provider before seeking medical care to avoid spreading measles.

CMDHD urges residents to verify their protection against measles by reviewing vaccination records. Residents can contact their doctor, check the Michigan Immunization Portal or call their local health department. You are likely protected if you have received at least one MMR vaccine, have documented immunity to measles, or were born before 1957.
