Notes: Saratoga Springs, NY: The New York Racing Association, Inc. (NYRA) and the New York State Gaming Commission have placed Barn 86 at the Saratoga Race Course under a precautionary quarantine until further notice due to a positive case of Equine Herpesvirus-1 in that barn. The unnamed, unraced filly with neurologic signs was sent to Rood and Riddle Equine Hospital on Sunday July 11th after developing a fever. On Thursday the filly subsequently tested positive for EHV-1. The filly began a treatment immediately and is improving. Overseen by the director of NYRA’s veterinary department in consultation with the NYSGC, the Barn 86 quarantine is effective immediately with standard precautions and biosecurity measures now in place. The 46 horses stabled in Barn 86 will be monitored daily for fever and other signs of illness. During the initial quarantine period, these horses will not be permitted to enter races or train among the general horse population. Afebrile/asymptomatic horses stabled in Barn 86 will have isolated training hours at the Oklahoma Training Track following the close of training for the general horse population at 10 a.m. For more information about EHV-1 go to:  EHV-1
