BERRIEN SPRINGS, Mich. (AP) -- Health officials say a strain of swine flu is responsible for an illness that sickened a child who recently attended the Berrien County Youth Fair in southwestern Michigan.
The state Department of Community Health announced Thursday it was the first case of H3N2 variant flu virus this year in Michigan.
The department says the child was a swine exhibitor at this month's fair. Officials say the child wasn't hospitalized. And a pig from the fair tested positive for Influenza A H3N2.
The state Department of Agriculture and Rural Development is involved along with the Berrien County Health Department.
Officials want to find out whether others became ill. They've also reached out to meat processing plants that got pigs from the fair.
