A veterinarian who specializes in dairy cows talks about avian influenza

In March 2024, for the first time in the United States, the highly pathogenic avian influenza (HPAI) H5N1 virus was recognized as having crossed over from birds into cattle. Experts believe the virus was transmitted a month or two beforehand from birds to dairy cows in the Texas panhandle, and then spread as the cows were moved to dairy farms in other parts of the country.
