COLUMBUS, Ohio (AP) — Health officials say the Ohio outbreak that helped push the number of U.S. measles
cases to a two-decade high appears to have ended.
March. Nine people were hospitalized.
The end of such 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.
Meanwhile, Ohio is tracking a separate outbreak of mumps, another contagious viral illness. Over half of
the 483 cases reported are linked to Ohio State University.
