Officials have determined an outbreak of equine herpesvirus has occurred at Hawthorne Race Course, located in Illinois, and a quarantine has been put in place, but racing will continue as scheduled.

The decision was made to put a quarantine of the affected barn in place to combat the disease, which has manifested in the neurologic form in two horses. The quarantine is restricted to Barn A.

"We’re treating the horses in there and monitoring the horses in Barn A, " said Hawthorne Assistant General Manager Jim Miller. " Horses can still ship in. It doesn’t affect racing. Racing still continues."

The disease claimed the life of one horse in Barn A and has affected at least one other. Three other horses are being monitored
