The Tennessee Department of Agriculture is investigating suspected cases of the Equine Herpes Virus (EHV-1). Horses that participated in a recent trail ride in Tennessee may be infected. Up to eight cases of the neurological form of EHV-1 have been reported to the state veterinarian’s office and the horses are being treated, isolated and monitored. The horses may have been exposed in Humphreys County during the Bucksnort Trail Ride back in April. The event drew about 100-horses from multiple states so the movement of horses that attended the event is being restricted on a case by case basis. Equine Herpes Virus is highly contagious among horses but poses no threat to humans. (bg)
