In a follow-up to reports of influenza A H3N2 variant (H3N2v) in Michigan and Ohio, the Michigan Departments of Health and Human Services and Agriculture and Rural Development today announced that there have been eight human cases of influenza A variant viruses reported in Michigan. They have tested positive for influenza A H3N2 variant (H3N2v) and one person has been hospitalized and since released.  All of the confirmed cases had exposure to swine at county fairs in Muskegon, Cass, and Ingham counties during July and August where sick pigs had also been identified.

MDHHS and MDARD are working closely with local health departments, the healthcare community, and fairs to protect swine exhibitors and the public and identify any additional cases.

In addition, a Centers for Disease Control and Prevention (CDC) FluView Report documents a third influenza A (H3N2) variant (H3N2v) in Ohio linked to exposure to swine in fair settings.

MDHHS and MDARD say fair exhibitors and animal caretakers should be following proper biosecurity processes such as regular handwashing with soap and water, disinfecting wash areas at least once each day and making sure it has time to dry  thoroughly after being disinfected. Additionally, weight scales and sorting boards should also be disinfected. Use a 10 percent bleach/water mixture in combination with a detergent (dish or laundry soap) to increase effectiveness.

Symptoms of H3N2v infection in people are usually mild and similar to those of seasonal flu viruses, but as with seasonal flu, complications can lead to hospitalization and death. Symptoms include fever and respiratory symptoms, such as cough and runny nose, as well as body aches, nausea, vomiting, or diarrhea. Some populations are at higher risk of developing complications if they get influenza, including children younger than five years of age, people 65 years of age and older, pregnant women, and people with certain long-term health conditions like asthma, diabetes, heart disease, weakened immune systems, and neurological or neurodevelopmental conditions.

The incubation period (the time it takes from exposure to illness) for this influenza is typically similar to seasonal influenza at about two days, but may be up to 10 days.  Currently, there is no vaccine for H3N2v and the seasonal flu vaccine will not protect against H3N2v. Antiviral drugs are effective in treating H3N2v virus infections. Early treatment works best and may be especially important for people with a high risk condition.

Below are some steps that you can take to protect yourself and prevent the spread of any illness:

  • Anyone who is at high risk of serious flu complications and planning to attend a fair should avoid pigs and swine barns
  • Do not eat or drink in livestock barns or show rings
  • Don’t take toys, pacifiers, cups, baby bottles, strollers, or similar items into pig areas
  • Avoid contact with pigs if you have flu-like symptoms. Wait seven days after your illness started or until you have been without fever for 24 hours without the use of fever-reducing medications, whichever is longer
  • Avoid close contact with sick people
  • Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it
  • Wash your 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
  • If you are sick, stay home from work or school until your illness is over
