Oklahoma Gelding Diagnosed With EIA, Euthanized

A 2-year-old grade gelding in Oklahoma was euthanized on July 15, 2019, after testing positive for equine infectious anemia (EIA), according to a Equine Disease Communication Center report released on July 26, 2019.

Equine infectious anemia is a viral disease that attacks horses’ immune systems. The virus is transmitted through the exchange of body fluids from an infected to an uninfected animal, often by blood-feeding insects such as horseflies. It can also be transmitted through the use of blood-contaminated instruments or needles.

A Coggins test screens horses’ blood for antibodies that are indicative of the presence of the EIA virus. Most U.S. states require horses to have proof of a negative Coggins test in to travel across state lines.
