Garfield County horse tests positive for EIA

A horse in Garfield County has tested positive for equine infectious anemia, which may cause fever, anemia, fluid accumulation on the chest or legs, and emaciation in some animals. The virus can also cross the placental barrier to cause fetal infection.

Many horses do not show any clinical signs of the disease or have very mild signs on first exposure, and carry the virus subclinically. All infected horses, including those that are asymptomatic, are potential carriers and are considered infectious for life.

Infected animals must either be destroyed or remain permanently isolated from other animals to prevent transmission. There is no vaccine to protect a horse against the disease.

The herd mates to this horse have tested negative to infection and neighboring horses will be tested to rule out any spread by insects.

“Identifying infected horses and restricting their contact with susceptible animals is the key to preventing the spread of this disease,”said state veterinarian Dr. Keith Roehr. “EIA is transmitted through biting flies, the most common would be deer and horse flies; horse owners can protect their herd by control biting flies around the stable and other areas where horses are kept.”

A blood test to detect the disease, called a Coggins test, is required for horses entering Colorado and is recommended for all horses that change ownership or attend equine events.
