Measles Outbreak Over?
State health officials say the measles outbreak that helped push the number of cases to a two-decade high appears to have ended. 377 confirmed cases have been recorded in nine counties since March. The end of an outbreak is measured 42 days after the onset of the most recent case, a window based on two, 21-day incubation periods. Ohio has passed that mark because the most recent onset date was July 23. The outbreak started among Amish in Knox County who traveled to the Philippines, which had a measles epidemic. The state says over half of the 483 measles cases reported in Ohio are linked to Ohio State University.
