As a owner, breeder and exhibitor of Quarter Horses we have been getting a lot of updates and alerts in regards to this. The EVH1 which is the neurological form of this virus reared its ugly head at a large cutting in Ogden as well as at a Southern California Cutting near Bakersfield. I have also heard reports of it now in Colorado. There is NO vaccine for this for of the virus either. It virus is shed by the horse through mucus & saliva while a horse is running the fever. From what I hear, the virus can last for awhile on stall walls, buckets, your own clothes, etc...., anything that a infected horse contaminates. IF you are traveling it is always a good idea to disinfect stall walls and doors, as well as any buckets, cross ties, etc.... PLus you should take your horses temperature every day if not twice a day. The first symptom is a fever! Any suspected horse should be isolated away from all other horses and a vet called. This is very serious and potentially devastating for all horses, both large and small!!
