Two people attending the Fowlerville Family Fair in Western Livingston County last month were infected with the influenza A virus.
The Centers for Disease Control tested respiratory samples from the pair, and found they were infected with H1N2, a similar strain of the influenza virus found in swine.
Both people reportedly were exposed during the fair between July 23 and 28. The CDC reported that during that same time, several pigs also tested positive for the virus.
Symptoms of swine influenza in people are a lot like seasonal flu, including fever, cough, runny nose and body aches, nausea, vomiting or diarrhea.
The CDC stated that though most people recover, complications in children under five years of age and people over 65 are possible.
Although there is no vaccine for swine flu, antiviral medications can help relieve symptoms.
Neither case of swine flu in Michigan seems to be spreading to other people they came into contact with, but the CDC says to take precautions when in handling pigs.
Over the past decade only 17 cases of influenza A have been reported to the CDC, including the two in Livingston County.
