STICKNEY, Ill. – No new cases of equine herpesvirus have been reported for 18 days at Hawthorne Race Course, and the track appears to be on the way out of a de facto quarantine imposed by the State of Illinois on Oct. 26. But the outbreak of the virus, known as EHV-1, is affecting the movement of horses to winter quarters at tracks like Fair Grounds in New Orleans, which opens its meet Nov. 22. Close to 100 horses from at least six trainers cannot depart Hawthorne for Fair Grounds until the Illinois Department of Agriculture lifts a ban on horses leaving the Chicago-area track.
