'Swine flu' case reported in Michigan
Michigan state health officials, along with Ingham County Health Department have identified a human case of influenza A H3N2 variant (H3N2v) in a resident of Ingham County.
The individual tested positive and was ultimately confirmed by the CDC for influenza A H3N2v in late July.
Influenza A H3N2v is often associated with pigs or swine, though the source of this person’s exposure is still under investigation.
“While we believe this is an isolated case, Michigan residents should monitor for flu-like symptoms: fever, respiratory symptoms like cough and runny nose and body aches,” said Dr. Natasha Bagdasarian, chief medical executive. “If you have these symptoms, we recommend taking a test for influenza as well as COVID-19. Home COVID-19 tests are widely available, and both flu and COVID-19 tests are available at many pharmacies, urgent cares and clinics. Regardless of test results, please stay at hom e until you have recovered.”
“As our partners continue to investigate this case, the Michigan Department of Agriculture and Rural Development is ready to assist if any connections are made to an ill animal," said Tim Boring, director Michigan Department of Agriculture and Rural Development director. “As part of our state’s One Health approach, our agencies are committed to collaborative action protecting both animal and public health.”

The Michigan Department of Health and Human Services (MDHHS) anticipates that risks of influenza A H3N2v to the general public are low. While the infection was not linked to known exposure to swine or other animals, MDHHS reiterates precautions the public can take to avoid potential exposure at farms, fairs and exhibits:
Refrain from eating or drinking in livestock barns or show rings.
Do not take toys, pacifiers, cups, baby bottles, strollers or similar items into pig areas.
Anyone who is at high risk of serious flu complications and planning to attend a fair should avoid pigs and swine barns.
Wash hands often with soap and water. If soap and water are not available, use an alcohol-based hand rub.
Avoid touching your eyes, nose and mouth. Germs spread this way.

While most individuals recover from influenza, including illnesses from variant viruses like H3N2v, these infections can sometimes cause severe disease, even in healthy people. If someone experiences respiratory symptoms, they should share any recent exposure to livestock with their doctor so that influenza testing can be considered. The same antiviral drugs used to treat seasonal flu can be used to treat H3N2v in children and adults. These treatments are most effective when taken early in the illness.
