Geldings and Equine Viral Arteritis (EVA)

Q. Is it possible for a gelding to have equine viral arteritis? I've read all about this disease in mares and stallions, but I have not read anything about it in geldings.


A. It is certainly possible for a gelding to develop this disease. All categories of horses are susceptible to infection with equine arteritis virus and might develop clinical signs of the disease. However, unlike the post-pubertal, intact male (colt, stallion), there is no evidence that the virus can become established and persist in the reproductive tract of the gelding. In other words, geldings do not become carriers of the virus.
