Disease Alerts

The Colorado State Veterinarian’s Office at CDA has continued to work to trace and test horses involved in the August 2018 EIA Incident in Colorado (the first EIA incident). As of 10/3/2018 the following has been confirmed:  1.) The index premises in Weld County is under a Quarantine Order; two associated premises are under Hold Orders. The exposed horses under quarantine on the index premises will be re-tested on or after 10/19/2018 (sixty days after last exposure to the positive horse). 2.) 63 premises are under Hold Orders in 24 Colorado counties: Adams, Arapahoe, Archuleta, Boulder, Costilla, Crowley, Delta, Douglas, Eagle, Elbert, El Paso, Fremont, Gilpin, Gunnison, Huerfano, Jefferson, Larimer, Mesa, Moffat, Montrose, Morgan, Phillips, Sedgwick, and Weld.  3.) Six premises have been released from Hold Orders after the 60-day re-tests were completed for all exposed horse(s) on those premises and found to be negative. 4.) 145 exposed horses have been located in Colorado (out of approximately 153 we expect to be in the state). CDA is working diligently to locate the remaining eight horses. 5.) 72 exposed horses have been located in 12 other states (out of approximately 81 we expect to be out-of-state): Arizona, Idaho, Kentucky, Louisiana, Maine, Missouri, Nebraska, Nevada, Oklahoma, Tennessee, Texas, and Wyoming. 6.) Many of the exposed horses will be eligible for their final 60-day EIA re-test over the next two weeks. The CDA has informed owners of exposed horses to work with their veterinarians to get the re-testing done after the date stated on their Hold Orders. The date varies depending on the last date that their horse was exposed to the EIA-positive horse. At this time only the exposed horses need to be tested, not all of the horses on the premises under the Hold Order.
