Sunland Park Racetrack and Casino, in New Mexico, has confirmed that one horse has tested positive for equine herpesvirus (EHV). The test results were released Jan. 21.

A statement from Sunland Park indicated that the affected horse was a 5-year-old Thoroughbred mare named Another Dollar, who was claimed on Jan. 9 after finishing fifth for a $5,000 tag by Karl Broberg from the barn of Roy Marcom, Jr. The horse became ill and was euthanized four days later.

“As of January 21, Sunland Park will not be allowing any horse on or off its grounds,” the track said in the statement. “The restriction will be in place until the environment is confirmed free from EHV. The teams on site are working diligently to disinfect all equipment, both personal and equine to prevent the spread of EHV. Sunland Park is planning to continue with live racing on Friday, January 22, as planned.”

The most common types of equine herpesvirus are Type 1 (EHV-1), which can cause abortions, respiratory disease, and neurologic disease, and Type 4, which usually causes respiratory disease, but can occasionally cause abortion. EHV-1 and EHV-4 infect the respiratory tract and can spread via aerosolized secretions from infected coughing horses, as well as direct or indirect contact with nasal secretions.

Clinical signs of the disease include fever, lethargy, anorexia, nasal discharge, and cough. Although EHV-1 can cause abortion outbreaks, EHV-4 has been associated with only isolated occurrences and is not a risk for contagious abortions.
