EHV-1 Surfaces Again at Racetracks in California

Dr. Rick Arthur, equine medical director for the California Horse Racing Board (CHRB), announced yesterday that two barns are under quarantine at Los Alamitos Race Course following the deaths of two horses from the Equine Herpes Virus (EHV-1). One was a stable pony and the other a racehorse. Lab results are pending on other suspected cases.

Elsewhere in California, a mare at Golden Gate Fields near San Francisco aborted a fetus, which subsequently tested positive for EHV-1, although the mare tested negative according to the CHRB. Biosecurity measures are in place at that track.
