Equine Infectious Anemia
Uintah County, UT
Outbreak Identifier: 4736
Alert ID: 2113
July 01, 2021
Confirmed Case(s) - Official Quarantine

Utah State Veterinarian

Number Confirmed: 4;
Number Exposed: 18;
Facility Type: Fairgrounds;
 Horse Status: 5 horses were euthanized; 
Notes: These horses were gathered in Uintah county with a band of feral horses and sold through an auction in Uintah county. They were resold a day later in Box Elder county to a Kansas buyer which prompted a Coggins test which was positive. Both of those horses (a mare and foal) were euthanized at the auction. There are traces on the horses that went through the auction on the same day and they are negative awaiting a 60 day retest. Because the horses originated in a feral band of domestic horses, additional horses were rounded up and three foals confirmed to be positive. These foals will be euthanized tomorrow. The remaining herd will be assessed and tested. One trace animal was transported to Colorado and is being tested.
