Fair Grounds' barn quarantined after equine herpes positive A barn in Fair Grounds' stable area is under a Louisiana State Racing Commission quarantine after test results confirmed that a horse in that barn was infected with equine herpes virus (EHV1). Officials have ordered biosecurity measures in place in Barn 4, which houses horses trained by Dallas Stewart and Neil Howard. The quarantine of that barn was ordered after a horse trained by Stewart displayed symptoms of equine herpes on Tuesday. That horse was transported immediately from Fair Grounds and is now under observation at Rood and Riddle Equine Hospital in Lexington, Kentucky, where the diagnosis was confirmed on Wednesday. The quarantine order affects 44 horses in Stewart's section of the barn and 27 horses under Howard's care. "The horse is doing well in Kentucky and starting to show some improvement," said Tom V. David D.V.M., equine medical director for the Louisiana State Racing Commission. "We remain cautious because we still do not have enough information. Until we get more test results on the horses in that barn, we don't know the total extent." Dr. David said the implementation of the quarantine and its associated biosecurity measures was ordered in an effort to contain and isolate any possible EHV1 cases to that barn and prevent any spread of the virus among the horse population at Fair Grounds. Symptoms of equine herpes virus most commonly include fever and an upper respiratory infection. The symptoms can also include lethargy, loss of appetite, a nasal discharge and a cough. In severe cases, horses can suffer a loss of coordination and an inability to stand and the illness can be fatal. The disease is a virus, so it can be spread through the air when a horse coughs -- although studies on the virus indicate that it is very short-lived and is susceptible to disinfectants. The maximum extent of the airborne transmission of the virus is thought to 35 feet. Horses may also contract the disease if they come in contact with the clothing of a person who has worked with an infected horse, the tack and equipment worn by an infected horse, or a shared food and water source. The recommended quarantine period for the disease, which poses no danger to humans, is generally up to 21 days after potential exposure to the virus. The incubation period ranges from two to 10 days. Under the quarantine order, horses may not be moved in or out of those barns until state agriculture officials clear them to do so. The quarantine is not expected to have a negative impact on Fair Grounds' season, which began November 14 and continues through March 29, as horses will continue to be permitted to ship in and out of the track to race. To accommodate the quarantined horses, training hours have been changed effective Saturday. Regular training hours will be 30 minutes earlier, from 5:30-9:30 a.m. (CST), with a renovation break from 7:30-8 a.m. Horses from Stewart and Howard's stables will be allowed to train from 9:30-10:30 a.m. Additional biosecurity measures have been put in place to guard against the introduction of the virus to the track's horse population. Those procedures include: -- Increased scrutiny
of horses that arrive and depart from Fair Grounds' barn area, with certificates
of veterinary inspection required for all horses that enter the stable area;
