  April 26, 2024 - CDC continues to respond to the public health challenge posed by a multistate outbreak of avian influenza A(H5N1) virus, or “A(H5N1) virus” in dairy cows and other animals in the U.S. CDC is working in collaboration with the U.S. Department of Agriculture (USDA), the Food and Drug Administration (FDA), state public health and animal health officials, and other partners using a One Health approach. USDA is now reporting that 34 dairy cattle herds in nine U.S. states, including most recently Colorado, have confirmed cases of A(H5N1) virus infections in cattle. The agency has issued a “Federal Order requiring Testing for and Reporting of Highly Pathogenic Avian Influenza (HPAI) in Livestock [118 KB, 2 pages].” Currently, one human case has been confirmed in a person with exposure to presumably infected dairy cows reported by Texas on April 1, 2024[1][2]. Monitoring people with exposure to animals infected or potentially infected with A(H5N1) viruses is important to help us better understand the risk to human health and potential for spread between animals and people.
