A sixth horse at PARX was confirmed positive for the neuropathogenic strain of EHV-1 on April 19th after it presented with a fever. That horse is located in the index case quarantined barn. All horses in the quarantined barns (the index case barn and the barn that had received a claimed horse from the index barn) continue to be monitored closely. Horses from barns not under quarantine are training and racing, as they have throughout this outbreak. Horses are not trailering into the track to race—all racing involves horses stabled on site. Track management has allowed a few horses to leave under carefully monitored movement for medical treatment at veterinary facilities. Those horses either return to PARX directly from the medical facility or they stay there in isolation until the PARX stable gate is reopened when the quarantines are lifted. In the absence of any new signs of EHV-1 in the barn that had received the claimed horse, that barn will be eligible to have samples taken on April 28th for quarantine release if all samples test negative for the neuropathogenic strain of EHV-1.
