USDA on March 25 confirmed the presence of Highly Pathogenic Avian Influenza A H5N1 (H5N1) on several dairy farms in the Southwestern United States. Since then, federal and state agencies, veterinarians and public health officials have been working tirelessly with the dairy community and academic institutions to investigate its transmission and provide up-to-date guidance for dairy farms to prevent its spread and protect public health. This webpage aims to provide comprehensive information on H5N1, its impact on dairy farms, and strategies for effective prevention and management.
