RECENT studies have shown that veterinary surgeons and horse owners must work together to reduce the risk of Equine Herpes Virus (EHV). EHV 1 and 4 are the most common stains of the virus. It is highly contagious and can cause respiratory disease, abortion and on rare occasions neurological disease.

In addition to the above, sub-clinical infections can be associated with a syndrome of poor performance and have a potential effect on the health of the whole yard.
