Majority Of U.S. Measles Cases Are In Ohio

The Centers for Disease Control says measles cases are at a 20-year high, and 60-percent of those cases are in Ohio.

Nearly 300 cases have been confirmed nationwide. 100 of those are in Knox County alone. Officials believe that outbreak started when a group of unvaccinated Amish people returned to Ohio from a trip to the Philippines, which is dealing with an outbreak of it's own.
