EIA Detected in Oklahoma Horse

A 15-year-old horse in Oklahoma has tested positive for equine infectious anemia (EIA), a viral disease that attacks horses' immune systems. The infected horse was euthanized, and the remaining 21 horses in the herd are under quarantine until state testing requirements are met. EIA is transmitted through the exchange of body fluids and can be spread by blood-feeding insects or contaminated instruments. Infected horses are carriers for life, and there is no vaccine or cure for the disease.
