Help us protect your animals from equine infectious anemia Equine infectious anemia (EIA) is a serious viral disease that exclusively affects horses, mares, donkeys, and mules. It does not affect humans or other animal species. EIA has no cure, vaccine, or treatment, and can cause severe symptoms that can even be fatal. Equines that survive become carriers, which increases the risk of contagion to other animals. Communications Communications Mon, 20/04/2026 - 13:54
