Horse suffering from neurologic form of EHV-1.
North Carolina officials have confirmed four horses were euthanized after contracting the neurologic form of equine herpesvirus (EHV-1) at a boarding stable. The farm, located in Raleigh, is under a state placed quarantine.
The last clinical signs of the virus were seen in a horse on Friday, December, 27 reportedly at J&H Stables. Bio-security measures remain in place and the quarantine at the farm will be held for 28 days from the last recorded fever. Dr. Tom Ray, director of Livestock Health Programs for the North Carolina Department of Agriculture and Consumer Services told us it has not been determined how the horses became infected with the virus.
Five horses were moved from the boarding stable in the the past month. The horses have been tracked to four locations in North Carolina where their health status is being monitored, according to officials. All known exposed horses have been accounted for and are not showing clinical signs. The horses originating from J&H Stables have not been moved since arriving at their destinations.
EHV-1 is highly contagious among horses, but poses no threat to humans. It most often causes respiratory infections in young horses, but different strains can also pose neurologic problems, which these horses exhibited.
The last known case in North Carolina of EHV-1 was in January 2012.
