Horses can be in close proximity to one another at a horse competition.
Since the outbreak of neurologicalEquine Herpes Virus-1 (EHV-1) disease at the University of Findlay four years ago, which took the lives of 12 horses and produced symptoms in 85% of the horses affected, further sporadic outbreaks of the neurological form of the disease have appeared at racetracks, training centers and most recently in the show-horse population, including an outbreak in Wellington, Fla. These Equine Herpes Virus outbreaks have caused concern, if not panic, throughout the equine industry.
EHV (aka the Rhinopneumonitis virus) exists in two forms. EVH-1 and EHV-4. EHV-1 is the most prevalent form. It can cause upper-respiratory disease (usually in animals under two years of age), abortion in pregnant mares, or neurological disease. Estimates are that from 60 to as many as 90% of adult horses are asymptomatic carriers of Herpes virus. These viruses are found in horses worldwide, with little variation between strains of virus around the world.
