MADISON, Wis. (AP) -- State health officials say 14 people exposed to pigs at the state or county fairs have been infected with a new strain of swine flu.

Department of Health Services officials say all 14 people were infected with the H3N2 virus. H3N2 can cause fever, lethargy, lack of appetite and coughing as well as vomiting and diarrhea.

All of the people were exposed to pigs at the Wisconsin State Fair in West Allis or at county fairs in Kenosha, Dodge and Manitowoc counties. They say most of the afflicted were children. One child was hospitalized but all the victims are either recovering or have recovered.

The U.S. Centers for Disease Control and Prevention reports 276 cases of H3N2 flu in humans since July across 10 states.
