The Colorado Department of Agriculture’s State Veterinarian’s Office is announcing a confirmation of a horse in Adams County positive for both Equine Infectious Anemia (EIA) and Equine Piroplasmosis. The initial positive was identified on December 8 during routine testing for movement, underscoring the necessity of Coggins testing for transport requirements. Confirmatory testing was completed at the USDA’s National Veterinary Services Laboratory (NVSL) on December 23, 2025. 

In the first confirmed case since 2020, the USDA’s Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic avian influenza (HPAI) virus in a commercial turkey flock in Indiana on February 8, 2022. Since then, HPAI has been detected in commercial poultry in Kentucky and backyard birds in Virginia. HPAI has also been detected in wild birds across many eastern and southeastern states as part of USDA’s routine surveillance program. There are currently no cases of HPAI in Colorado.
