Show Smart: Be Aware of Equine Virus Outbreaks

Horse trailer packed. Check. Tack cleaned. Check. Show clothes ready to go. Check. You’re eager to hit the road for the next horse show, but do you know what could be waiting for you when you get there?

With a lot to think about for show preparation, checking for equine disease outbreaks can often fall off the to-do list. While vaccinations are an essential part of maintaining equine health1 and helping show season go smoothly, it’s best to avoid a run-in with an infectious disease altogether.1

Believe it or not, this year’s biggest threat is rabies. With over 400 cases of rabies reported in various animals, it is a danger that horse owners have to protect against.2 Texas has the highest number of reported rabies cases at 194 and counting, and most of those cases were bats.2 While you may not think heading to a show could expose your horse to rabies, wildlife such as raccoons, coyotes, and feral cats may often be found in and around barns and wooded show facilities. Rabies is preventable with vaccination–and in fact, the American Association of Equine Practitioners (AAEP) considers rabies a core disease for which all horses in the U.S. should be vaccinated.3 Once clinical signs develop, rabies is almost always fatal, since no treatment is currently available.3

Another prominent threat, equine herpesvirus (EHV), has almost doubled this year from last.2 The virus has been reported 81 times, and more than 85 percent of outbreaks were reported in the Southwest part of the United States.2 That’s something to keep in mind when heading to shows in the area or if horses that have traveled to that area will be coming back into your barn.

EHV can spread through direct horse-to-horse contact and even indirectly through contact with contaminated objects. That means interactions with contaminated feed, equipment and tack, or human hands and clothing can spread the disease.4
