What is EHV  – Equine Herpes Virus

The Animal Health Trust tells us on their website:

The disease is a major welfare concern for horses and foals. It can strike any horse at any time, causing emotional, as well as financial strains, on horse owners and breeders around the world. Currently, there is no vaccine effective against all forms of the disease.

Equine Herpesvirus can cause a seemingly healthy pregnant mare to suddenly, and without warning, miscarry her unborn foal.

It can cause a horse which appears fit and well to suddenly show abnormalities when walking and within hours be unable to stand.

It can also cause respiratory disease, similar to a cold, which can easily spread from horse to horse.The virus lies dormant and then re-emerges when an animal is later stressed, such as when transported or mixed with new horses.

Further to the recent outbreak of neurological EHV-1 at an equestrian centre in Hampshire, which has resulted in the deaths of three horses, the Animal Health Trust (AHT) has been undertaking laboratory testing and analysis of samples taken from horses connected with the equestrian centre. The results have proven useful in identifying where the infection has been active and support the current veterinary advice on biosecurity.

Dr Richard Newton, Director of Epidemiology and Disease Surveillance at the Animal Health Trust, commented: “Our laboratory testing and analysis of the samples taken from horses associated with the yard has provided us with useful information on the scale of infection. Previous advice on biosecurity for the venue, and horses connected with this premises, remains the same and further testing will be required over the next couple of weeks.”

Dr Newton added: “The swift action from horse owners and vets from the outset of this outbreak is to be commended. However, it is important that the shutdown remains in place for now and further testing is carried out before any restrictions are relaxed. If any horse owner is concerned about their horse’s health, they should consult their own veterinary surgeon for advice.”

The Animal Health Trust (AHT) is aware of a confirmed outbreak of neurological EHV-1 in horses at an equestrian centre in Hampshire and that an event was held at the venue last weekend. The AHT understands that the premises is taking veterinary advice and is managing the situation extremely responsibly…………

Dr Newton added: “We would encourage all horse owners to maintain good biosecurity practices and be aware of the clinical signs of EHV-1 infection. These can include a raised temperature, inappetence and lethargy, nasal discharge, coughing and in some cases neurological signs that may range from slight hindlimb weakness through to recumbency and inability to stand. If an owner has any concerns about their horse’s health, they should consult their own veterinary surgeon for advice.”
