County Officials Say 'Fair is Not to Blame' for H3N2
Ingham County officials are not taking the blame after a Washtenaw County child caught a new strain of swine flu. The recent exposure to swine started at the fair which ended over a week ago.
County officials sent 6 News an email from the fair veternarian that said this: "No animals brought to the fair exhibited any symptoms that would indicate they were ill with H3N2 swine flu" and that they've followed all the proper procedures.

"A pig can carry it up to three months and not be sick, but they can still transmit it to other pigs," said Kent. "It can spread from pig to pig and can be a serious outbreak. Typically it's not something that causes death in the pig."
