Ohio EHV-1 Outbreak; One More Neurologic Horse

One more horse has shown neurologic signs of equine herpesvirus type 1 (EHV-1) in the outbreak which began Jan. 12 at the University of Findlay's English riding facility in Findlay, Ohio. Twelve horses have died during the outbreak, and at least 43 horses have exhibited neurological signs of the disease (including the 12 which died). The latest neurologic case is considered stable, and veterinarians at the university seem confident that the outbreak is drawing to a close.

"There was one fever in the past week," said Rick Henninger, DVM, a veterinarian at the university. "That horse has also shown neurologic signs, but was treated and is stable. In other words, we don't anticipate at the present time that
the horse is going to become recumbent." He explained that the horses in the outbreak which became recumbent did so quickly after onset of neurologic signs, and this horse exhibited its first neurologic signs three days ago.

He said while there is no guarantee with EHV-1 that a horse will recover, generally it's more encouraging when the horse doesn't become recumbent.

The latest case was a little different in that most horses because didn't show neurologic symptoms until six to seven days after the fever. This horse showed neurologic signs on the fourth day. "We were checking temperatures religiously so we feel confident (that we caught the horse's fever on the day of its development," said Henniger.

The University of Findlay will remain under quarantine until three weeks have passed without detection of a new fever. Henninger said there are fewer cases to be examined and maintained than earlier in the outbreak, and there has been a minimum number of people in the facility to avoid potential breaks in quarantine protocol.

"There is a guard out in front of the facility," said Henninger. "He has a list of names, and only certain people are allowed on this property."
