For those of you in the horse competition world, hopefully you've heard about the recent alarm with Equine Herpes Virus (EHV-1). Several horses recently competed in the National Cutting Horse Association Western National Championship in Ogden, Utah on April 29-May 8 were diagnosed. They then traveled back home and infected other horses. Reports of affected horses have been received from multiple states and western Canada, with several fatalities- and that number is growing.
The major issue with this disease, other than killing horses, is how easy it spreads. It's airborne; it can be contamined through people's hands, equipment, clothing, trucks, etc.
USDA has posted links with information about EHV-1 and a copy of the situation report at http://www.aphis.usda.gov/vs/nahss/equine/ehv/ Be careful out there!
