Our friends at The Blood-Horse are reporting that three horses at Los Alamitos racetrack in Southern California have tested positive for Equine Herpes Virus, Type 1 (EHV-1).

Los Alamitos is best known for its after-dark Quarter horse racing circuit, but it is also unique in that, at different times, you might find Thoroughbreds, Paints, Appaloosas, or Arabians racing there too. The track is located south of Los Angeles, between Long Beach and Anaheim.

Last week, as reported in this blog, California state officials quarantined three racetracks in Northern California when a racehorse tested positive for EHV-1.
