      Ohio swine flu cases rise

      This is how swine flu changes to infect humans.

      The number of people infected with swine flu has risen to 54. According to the Ohio Department of Health many of these people had contact with hogs at fairs.

      As of yet, officials say they haven't found any Ohio cases of the virus spreading from person to person.

      The confirmed cases involve children 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.

      Health officials are urging people attending fairs to wash their hands frequently before and after exposure to animals.
