Veterinarians believe a horse's death in Washington County was caused by Potomac Horse Fever, and want to remind horse owners that vaccinations for the disease are available.
Dr. David Spindler, a veterinarian at Meadow Green Veterinary Hospital, says the fever is normally found during the Summer or early Fall in horses near streams or rivers.
He says the disease is not passed from horse to horse, and is caused by a type of worm transported by snails and flies.
"It's not an epidemic. I want to make that clear. It's a sporadic disease, but it's a disease you'll most likely have a lot of trouble and expense in saving the horse," Dr. Spindler said.
He also says that horses who do get Potomac Horse Fever have a mortality rate of about 60 to 70 percent.
