ALLEGAN, Mich. (AP) - Health officials say a child who visited a county fair in western Michigan last month is the first confirmed case of swine flu in the state this year.
The Michigan Department of Health and Human Services and the Allegan County Health Department reported the child visited the Allegan County Fair that ran Sept. 8-16, 2017. They say that because the incubation period for the illness is one to seven days, no new cases from exposure at the fair are expected.
The flu is known as a variant of H3N2 and there's currently no vaccine for it.
Symptoms of swine flu in people can be similar to other flu viruses: fever, cough, runny nose, aches and nausea.
