The horse was tested for routine movement purposes in Fremont County, where it is currently under a quarantine order.

The investigation is ongoing but appears to be unrelated to the prior three cases of EIA in Colorado this year.

The initial test was completed at Colorado State University’s Veterinary Diagnostic Laboratory in Rocky Ford with the confirmatory test completed at the National Veterinary Services Laboratory (NVSL) in Ames, Iowa, on December 4, 2018.

“The current risk to the general equine population is low at this time, given that we are at the end of fly vector season in Colorado. This disease occurrence also highlights the importance of disease prevention practices, such as not sharing needles, syringes, tack, and equipment along with routine testing for EIA,” said State Veterinarian, Dr. Keith Roehr.

A negative EIA test (Coggins) is required to cross state lines in the United States. It is also recommended that all equestrian shows, rodeos, fairs, and other equine events consider requiring a negative Coggins for entry, even if the horses haven’t crossed state lines. Coggins tests are also recommended as an important component of a pre-purchase exam.
