The Wyoming Department of Health said on Friday it has identified its first human case of H5N1 bird flu in the region, making it the third confirmed instance of hospitalization related to the infection in the United States.

The state’s first human case of bird flu in 2025 has been reported in the Miami Valley. As reported on News Center 7 at 6, it’s infected thousands of chickens, ducks, and turkeys in the Miami Valley and now a person.

A Mercer County farm worker came into contact with dead poultry that was infected with the disease, the state's health department reports.

The new study is more evidence that the official U.S. tally of confirmed human bird flu infections—68 in the past year—is likely a significant undercount.

A new study shows that bird flu has silently spread from animals to some veterinarians. The study published Thursday by the Centers for Disease Control and Prevention echoes two smaller ones that detected evidence of infection in previously undiagnosed farmworkers.
