State veterinarian’s office investigates Colorado Equine Herpesvirus case
BROOMFIELD, Colo. — On April 18, the State Veterinarian’s Office was notified that a Weld County horse tested positive for Equine Herpesvirus (EHV-1). This time of year typically kicks off horseback riding, jackpots, horse shows and a number of other horse events and the Colorado Department of Agriculture reminds horse owners that there are a number of steps to protect their horses this season.
CDA is investigating the positive case and has placed the stabled area of the facility where the horse is housed under quarantine. The horse is undergoing treatment and others it may have come into contact with are being monitored but are not showing clinical signs of the disease at this point. At this time, the affected horse that showed clinical signs of disease is recovering.
“The most common way for EHV-1 to spread is by direct horse-to-horse contact but it can also spread through the air, contaminated equipment, clothing and hands; this certainly highlights the importance of practicing basic biosecurity practices,” said State Veterinarian Keith Roehr. “Equine event organizers should continue to practice routine biosecurity practices that are effective in the prevention of EHV and other horse diseases as well.”
Symptoms of horses affected with EHV-1 include fever, decreased coordination, nasal discharge, urine dribbling, loss of tail tone, hind limb weakness, leaning against a wall or fence to maintain balance, lethargy and the inability to rise. While there is no cure, the symptoms of the disease may be treatable. EHV-1 is not transmissible to people; it can be a serious disease of horses that can cause respiratory, neurologic disease and death.

Basic biosecurity practices can reduce the risk of exposure to diseases. Key points of a biosecurity plan include isolating new animals and those returning from equine events to the home premises, supplying clean feed and water, implementing infection-control practices for visitors and personnel and avoiding movement from various locations if possible. Especially important is the isolation of any sick horses. Horse owners are encouraged to contact their veterinarian if illness appears in their herd.
“Effective biosecurity practices lead to fewer health problems for animals and contribute to a longer and better-quality life for the horse,” said Roehr. “When you’re traveling with horses, something as simple as a clean water bucket that you don’t share with other people’s horses can greatly reduce the risk of disease spread.”
