Remington Park’s two new confirmed cases of equine herpesvirus posted late Thursday by the Oklahoma Department of Agriculture are asymptomatic cases and both horses have been placed in isolation in a small, empty barn on the backstretch, said Matt Vance, the track’s vice president of operations.

Vance said the horses are not sick. The state’s posting on the animals indicated neither had a fever. Last week, one horse was euthanized and tests later confirmed EHV-1.

“We are very fortunate that right now, we don’t have any other sick horses at this time,” Vance said.

Vance said 100 horses were tested by the state, including some pony horses.  

The three cases came from two barns and those barns are under a 14-day quarantine. Vance, who declined to name the barns under quarantine, said the state will test the horses every seven days. If there are no new cases in two seven-day blocks, the quarantine is expected to be lifted.

Remington long has had strict requirements in place for vaccinations that would address equine herpesvirus, said Vance, and he believes those policies are helping keep what can be a contagious virus in check.

“We haven’t seen a rampant case after case,” he said.

Remington closes its meet Dec. 15 with a significant race, the $400,000 Springboard Mile. It is a points race for the Kentucky Derby and it anchors a program of six stakes. Vance said he has received Oklahoma Racing Commission approval to extend the deadline for nominations for those races by a week, to Dec. 7, with the anticipation quarantines will be lifted by Dec. 5. Entries for the Springboard Mile are Dec. 11.
