Hawthorne EHV-1 Still Under Close Watch

The outbreak of equine herpesvirus-1 (EHV-1) at Hawthorne Race Course, near Chicago, Ill., appears to be under control, but remains under close watch, according to a Dec. 19 statement from assistant manager Jim Miller.

In the statement Miller said that 18 days have passed since the last EHV-1-related death at the racetrack, and some horses that previously tested positive have retested negative. Those horses have been moved back into their barns from the quarantine area, he said.

"We have ... recently had some asymptomatic horses that have been tested and tested positive for EHV-1," he said. "Those horses have been required to be relocated to a quarantine location until they test negative."

"Horsemen have been asking when the quarantine will be lifted," Miller said in the statement. "There is no firm date."

He noted that 28 days since the last death has been listed in protocols as the time passed before quarantine can be lifted; however, that is the timeframe for when talks with the state department of agriculture will likely begin to allow the quarantine to be lifted.

"That is not a set in stone time for an end to the quarantine," he said.

Horses are not currently allowed to ship to Hawthorne, Miller said, and a decision on when shipping in will begin again will be made after the track's fall race meet concludes at the end of the month. Protocol for shipping horses out of Hawthorne is in place, Miller said, and can be accessed in the veterinarian's office in Barn 8.

"As always, we ask that horsemen continue to use proper care and hygiene around their horses and relay the same to their staff," he continued in the statement.
