ALBANY, Calif. - Two additional horses in trainer Lloyd Mason's barn at Golden Gate Fields have tested positive for the equine herpesvirus, but they are showing no symptoms of the disease, said the California Horse Racing Board's equine medical director, Dr. Rick Arthur, on Tuesday. They are the second and third horses to test positive for equine herpes at Golden Gate. No horse outside of the Mason barn has tested positive.
Dr. Arthur called the test results "not terrible, but not great."
