A horse stabled in the Grand Prix Village (located outside of the Palm Beach International Equestrian Center in Wellington, Fla.) was tested for equine herpesvirus-1 (EHV-1); the animal tested negative for the nasal PCR (polymerase chain reaction) swab, but positive on blood test, according to a statement from show organizers Equestrian Sport Productions.

The affected horse has not shown any neurologic signs and there are no sick or horses or horses with positive EHV-1 tests on the PBIEC property, the statement relayed.

According to the statement, "The horse that was tested was never on the PBIEC property and was isolated on the private property in Grand Prix Village. However, two horses from that Grand Prix Village farm were moved into the Fédération Equestre Internationale (FEI) stabling at PBIEC. Within FEI stabling, those two horses had no other horses directly next to them or behind them, and those two horses couldn’t touch noses with other horses. The closest horses to the two exposed were across a 12-foot aisle.

"On the evening of Tuesday, Feb. 26, the two horses from Grand Prix Village that were in FEI stabling were moved back to their farm in Grand Prix Village on the recommendation of the state veterinarian and that farm in Grand Prix Village is under quarantine
