A 65-year-old man is the first Ohioan to be diagnosed in the meningitis outbreak that has killed seven and spread to nine states.
Health officials say they aren't releasing where the man lives to protect his identity.
The outbreak has been linked to steroid injection from the New England Compounding Center, a Massachusetts pharmacy that has now recalled all of its products.
The steroids were injected into people suffering from back pain from July through September.
