The Swine Flu is back, in a different mutation, and directly linked to swine.
A total of 30 human cases are now confirmed in Ohio, 14 from the Butler County Fair, among people who had contact with pigs.
And two sick pigs were found and removed from the Ohio State Fair.
Several county fair boards are deciding to eliminate their swine exhibits this year.
This variant of the flu, called H-3-N-2, is making people a bit frightened about being around pigs, or even about going to fairs and festivals at all.
"If you're planning to go to the fair, go to the fair," advises Rob Sproul of the Belmont County Health Department. "Don't be afraid. It's just a matter of basic hand-washing. If you touch the animals, just make sure you wash your hands before you touch your mouth or eat anything. It's basically just normal hygiene. Wash your hands after you touch the animals."
Health officials say older adults, pregnant women and very young children should be especially careful around livestock.
They say everyone should wash their hands with soap and water immediately after visiting the animal barns.
They advise using alcohol based hand sanitizer if soap and water are not immediately available.
