A pony recently brought to a New Jersey stable from a sale barn in Pennsylvania was confirmed positive for equine infectious anemia. Officials in Pennsylvania are investigating the source of the infection. The pony, which had been obtained by an equine rescue group, was euthanized.

Equine infectious anemia (EIA), also called "swamp fever," is an infectious, viral disease that can infect all equidae (horses, donkeys, zebras, etc.) It is not infectious to humans. There is no effective treatment or approved vaccine available.

The disease is spread via blood-to-blood transmission, usually from horse to horse by large biting insects such as horseflies and deerflies. Blood transfusions, unsterilized or contaminated needles, and equipment contaminated with blood from an infected horse can also spread the virus.

Depending on an individual horse's immune system and the severity of its reaction, clinical signs of EIA can range dramatically. While some animals infected with EIA show no signs of illness, others display fever, weight loss, icterus (yellowing of body tissues), anemia, swelling of the limbs, weakness, rejection of feed, and/or sudden death
