Virus that has killed scores of birds turns up in first wild mammal in Minnesota

A fox kit from Anoka County has tested positive for a deadly, highly contagious bird flu that has killed countless wild birds this spring to the concern of wildlife specialists.

The positive case is the first confirmed of highly pathogenic avian influenza, or HPAI, in a wild mammal in Minnesota, according to the Department of Natural Resources.

It’s not unprecedented — two red fox kits in Ontario tested positive last week for the flu strain, the DNR said in a news release Wednesday. They were the first reported cases in mammals in North America.

The University of Minnesota Veterinary Diagnostic Laboratory alerted the DNR to the kit’s case. DNR wildlife health specialists will add bird flu to the routine screening when sick foxes are brought to the lab, the agency said.

Some waterfowl like ducks and geese are considered hosts for bird viruses, which spread as they migrate. The current outbreak, which originated in Europe, has been more widespread and aggressive than the last outbreak in 2015, and it has dramatically affected the poultry industry, too.

Waterfowl have been hit hard and, in turn, the raptors that have eaten their dead bodies. The DNR said testing so far in Minnesota has confirmed bird flu in about 200 wild birds, including 19 species.

The Centers for Disease Control and Prevention and other health officials have said the risk to the public remains low.

“The best advice we have for Minnesotans is to avoid contact with wildlife that appear sick or injured and contact your health care provider if you are bitten or have other close contact with wildlife,” said Dr. Joni Scheftel, Minnesota Department of Health public health veterinarian, in the DNR news release.

People who see sick or dead birds are encouraged to call the DNR hotline at 888-646-6367.
