Another horse in Colorado tested positive for EIA, a contagious infection that horse owners should be aware of.

The Colorado Department of Agriculture's State Veterinarian's Office was notified of the fourth case of Equine Infectious Anemia this week. The horse was tested for routine movement purposes in Fremont County. The animal is currently under a quarantine order.

Equine Infectious Anemia is a viral disease spread by bloodsucking insects, inappropriate use of needles, or other equipment used between susceptible equine animals such as horses, mules and donkeys. Horses may not appear to have any symptoms of the disease, although it can also cause high fever, weakness, weight loss, an enlarged spleen, anemia, weak pulse and even death.

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

“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.

Updates on Prior Cases:

-August 2018 EIA Investigation: The index premises in Weld County and two associated premises have been released from their quarantine and hold orders. 149 exposed horses have been located in Colorado (out of the 149 that we determined to be in the State) at 66 different locations. Fifty-eight hold orders have been lifted in Colorado; 8 hold orders remain in Adams, Boulder, Huerfano, Jefferson, Larimer and Weld counties until final testing is completed.

-September 2018 EIA Investigation: The index premises and associated premises have been released from their quarantine and hold orders after all horses tested negative for EIA.

-November 2018 EIA Investigation: All associated horses have tested negative for EIA and have been released from their hold orders.
