Health officials say no measles cases have been reported in Ohio since mid-July, while mumps cases continue to be tallied. 377 cases of measles have been reported in nine counties, with the last on July 23. The state will consider the outbreak officially over at the conclusion of two 21-day incubation periods. Measles are at a two-decade high in the United States, driven by outbreaks among unvaccinated populations of Amish in Ohio. The outbreak started among Amish in Knox County who had traveled to the Philippines. Columbus Public Health spokesman Jose Rodriguez says the agency is working with schools to ensure students' vaccinations are current. He also says two to five cases of mumps have been reported each week for the past month.
