Michigan's first measles case of 2025 was reported Friday in an adult from Oakland County who recently returned from international travel, and likely exposed people in three instances from March 3-10 at a restaurant and hospital in Rochester, said Kate Guzman, Oakland County health officer.

"And honestly, we got very lucky because the only other exposures are those two visits to the emergency room," Guzman said. "It's a very unusual in a measles case."
