The Ohio Department of Health says the number of swine flu cases in Ohio has increased to 54, and most involve people who had contact with hogs at fairs.
Officials say they haven't determined any Ohio cases of the virus spreading from person to person. The confirmed cases involve people between the ages of 6 months and 36 years old. Five of them were hospitalized but have since been treated and released. Officials say the current strain of the virus appears mild and is similar to a seasonal flu that responds quickly to treatment.
