According to the Colorado Department of Agriculture – eight cases of Herpesvirus have been confirmed in the state. Confirmatory tests are pending on 22 other suspected cases. Colorado officials say 10 quarantine and hold orders have been issued in Bent, Boulder, Larimer, Mesa, and Weld counties. But, no travel restrictions have been ordered. However, that’s not the case for horses coming into the state.
The Colorado Department of Agriculture reports standard requirements for horses entering Colorado include a health certificate issued within 30 days of their arrival and a negative Coggins test within 12 months. The new requirements, just established, consist of a permit to enter the state. Horse owners who wish to bring their horse into Colorado must first call their veterinarian.  That veterinarian can then contact the Colorado Department of Agriculture’s State Veterinarian’s Office and request a permit number.  That number would then be included on the health certificate.
Officials believe the EHV-1 virus spread at the National Cutting Horse Association’s Western National Championships held in Ogden, Utah. So far, two horses have been euthanized.
