CDC warns of 12 new cases of swine flu, 10 linked to swine exposure at county fair in southwest Ohio

Centers for Disease Control and Prevention officials in Atlanta say 29 human cases of the new strain of the H3N2 swine flu have been confirmed in the last year, including 12 last week. Ten of the new cases were linked to the Butler County Fair in southwest Ohio, which ended last weekend. The county is just north of Cincinnati. None of the cases have been tied to human-to-human transmission, and all 12 of the new patients had close contact with swine before getting sick. The two other new cases occurred in Hawaii and Indiana. (CBS News photo)
