VERMONT — Since early March 2024, the U.S. Department of Agriculture, Food and Drug Administration, Centers for Disease Control and Prevention, and State veterinary and public health officials has been investigating an illness among primarily older dairy cows. The illness is called highly pathogenic avian influenza.

Vermont veterinarians continue to monitor the situation as it develops and are learning from other states and officials around the country. As of May 1, 2026, no cases have been detected in Vermont and no links to affected states have been identified.
