Ohio has confirmed 45 measles cases so far this year, a total that took all of 2025 to accumulate, according to figures the Ohio Department of Health reported. Wayne and Trumbull counties recorded their first infections of the year as part of the state's third and still growing outbreak.
The trajectory is steep. A week before that count was published, the state health department had reported 15 cases for the year. Ten Ohio counties now have confirmed cases, with the largest burdens in Geauga County, Tuscarawas, Ashtabula, and Cuyahoga. Geauga has 13 cases, Tuscarawas eight, and Ashtabula and Cuyahoga seven each.
