Equine Herpesvirus- Respiratory
Louisiana, United States
Alert ID: 405
December 27, 2016
On Dec 26, 2016 the State Veterinarian’s Office confirmed a positive PCR tests of nasal swabs and blood for the EHV-1 neurotropic strain in a 2-year old Thoroughbred gelding at the New Orleans Fairgrounds Race Track. The horse had been at the Fairgrounds since Dec 4, 2016 and broke with a fever on Dec 20th with no neurological signs. The horse responded to symptomatic treatment until Dec 25th when it developed neurological signs, was subsequently euthanized on the 26th and taken to the LSU school of veterinary medicine for necropsy. The horse was confined to its stall in Barn #14 since Dec 20th and had no direct contact with any other horses, but Barn 14, which houses 46 other horses, is currently under quarantine by the LA State Veterinarian’s Office. Horses will be monitored and have temperatures twice daily with increased biosecurity on the premises. An investigation with the State Racing Commission is currently under way.
