Bird flu infects many species, including wild animals, according to the United Nations. Ducks, quail and at least one eagle have been euthanized due to the virus. A global outbreak of H5 bird flu has infected millions of animals since 2020. The virus can infect chickens, cows and, more rarely, humans.

The first case of bird flu in a human in Ohio has been reported, according to officials. A farm worker from Mercer County, Ohio, located on the state's western border along Indiana, came into contact with deceased poultry that was infected with the virus, the Ohio Department of Health announced on Wednesday.

With so much H5N1 circulating in the U.S., scientists worry we are a few mutations away from a potential human pandemic.
