The Centers for Disease Control is urging fairgoers to be careful around pigs because of a new strain of flu spreading to humans.
Officials say 29 human cases of the new strain of swine flu have been confirmed in the U.S. in the last year – most of them children. Ten of the 12 cases confirmed just this week were linked to the Butler County Fair in Southwest Ohio, which ended last weekend.
Fairgoers are advised to wash their hands and avoid taking food and drinks into livestock barns. Pregnant women, young children, the elderly and people with weakened immune systems should be particularly careful.
