H5N1 avian influenza, or bird flu, continues to rip across the U.S. In just the last few months, it’s infected at least three people—all dairy workers—while spreading among chickens and cows in dozens of farms across several states.
Government officials and farmers have been responding to H5N1 since Feb. 2022 when the virus was first detected in U.S. poultry farms. When it spread to dairy farms in recent weeks, the U.S. Departments of Agriculture (USDA) and Health and Human Services (HHS) immediately surged their response efforts—ensuring the safety of our commercial milk supply, educating health care providers, scaling up testing, and ordering the production of millions of vials of H5N1 vaccine—with coordination support from the White House Office of Pandemic Preparedness and Response and National Security Council.
