TAMPA, Fla. — The Florida Department of Health in Hillsborough County says they've identified a positive case of Hepatitis A in a person who worked at Hamburger Mary's Bar and Grill in Ybor.

Officials say the person worked at the restaurant October 4 through October 20. They say anyone who frequented the restaurant during that time who hasn't been vaccinated for Hepatitis A should get the vaccine. If you have had the vaccine, you don't need to take any action.

Hepatitis A is a highly contagious liver infection caused by the Hepatitis virus. The best way to prevent it is to receive the vaccine.
