The Pennsylvania Department of Agriculture has announced that a stable in Enon Valley, in Lawrence County, has been quarantined after a horse on the premises tested positive for equine infectious anemia (EIA).

A statement on the Equine Disease Communication Center’s website said the Pennsylvania Veterinary Laboratory returned the initial positive May 11, and confirmation from the National Veterinary Services Laboratory came May 21.

There are 34 other equids (including horses, Miniature Horses, and miniature donkeys) on this premises that are under quarantine. The index horse has been stabled at the farm for the past three years, and the state agriculture department is investigating that horse’s movement history and any other potentially exposed horses.

Equine infectious anemia is an incurable infectious disease of horses spread by biting flies, such as the horse fly and deer fly, and more rarely through the use of blood-contaminated instruments or needles. The disease can 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 disease or have very mild signs on first exposure and carry the virus subclinically.  The most common blood test to detect the disease is the Coggins test
