Avian influenza updates

The current outbreak (2021-22) of highly pathogenic avian influenza (HPAI) is affecting wild and domestic birds throughout much of the United States, including Michigan. Additionally, Michigan’s first confirmation of HPAI in a wild mammal occurred May 11, 2022, in three red fox kits from separate dens in Lapeer, Macomb and St. Clair counties.

In an effort to detect this virus in wild birds, the DNR is performing passive surveillance, meaning that we are testing wild birds that were found dead. The emphasis is on testing highly susceptible groups of birds such as waterfowl, raptors, and scavengers. Here are some things to keep in mind about the situation and the DNR's testing procedures: 

  • We are sampling using a watershed based approach where we collect and test birds from within a given watershed boundary and once sufficient detections have been made in that region, we distribute our sampling resources to other parts of the state. This is more efficient than testing birds at the county level and ensures that we have adequate representation around the state. We will continue to test birds from areas of public health concern, in close proximity to domestic birds, and high profile species or situations.
  • Make sure domestic poultry (e.g., chickens, turkeys, geese and ducks raised for the production of meat or eggs) is separate from and has no contact with wild birds.
  • This virus primarily affects birds, but it is important to remember that it can be a zoonotic disease or a disease transmitted from domestic or wild animals to humans. You should avoid handling any sick or dead wild birds, but if it is necessary to move a dead bird, use a plastic bag or shovel to do so and wash your hands thoroughly after. You may also report them to wildlife professionals who can offer guidance.
  • While the CDC considers the risk to the general public from HPAI H5 to be low, people who have close contact with infected birds are at higher risk and should take appropriate protective actions. For additional human health information, please visit the CDC website: Bird Flu Current Situation Summary | Avian Influenza (Flu) (cdc.gov).
  • We welcome reports or observations of unusual or unexplained deaths among wild birds or sick, dead or neurologically abnormal foxes to local field offices or calling the Wildlife Disease Lab at 517-336-5030. We also encourage reports through the DNR’s Eyes in the Field app. Choose the “diseased wildlife” reporting option.
  • Every bird or fox may not be tested for HPAI, but all observations are important even though you may not receive a direct response from the DNR after submitting.
