Missouri horse owners are on alert for signs of a rare horse disease after an outbreak in 12 horses in Nebraska earlier this month.
Equine infectious anemia, or EIA, is a viral disease spread by biting insects and the sharing of medical needles between horses. While the virus is related to HIV in humans, EIA can only be contracted by horses, donkeys, and mules.
Dr. Phillip Johnson is a professor of equine medicine and surgery at the University of Missouri. He says the most common outcome for an infected horse in North America is euthanasia.
