EHV 1 Outbreak in Europe 2021

**Important – Equine Herpes Virus (EHV-1) Outbreak**

Many of you may be aware of the recent EHV-1 outbreak that originated at a British Showjumping event in Valencia (Spain) and has subsequently resulted in related outbreaks in at least 3 other countries in Europe.

In response, British Showjumping are putting in place measures for all horses returning from France, Spain, Portugal, Belgium, Italy, Austria, Poland, Netherlands, Germany and Slovakia from 1st March 2021. See link:…/British…

The FEI have also cancelled shows in Europe ( with the exception of a strictly controlled few that are already well underway) until 28th March ’21.

What is EHV?

Equine Herpes Virus is a common equine virus that can cause respiratory or neurological signs in horses and abortion in pregnant mares. It is extremely contagious, spread via direct horse contact through respiratory secretions or via indirect contact with contaminated items/ personnel etc.

Neurological disease (EHM) has been associated with this recent outbreak. Neurological signs can vary from incoordination (ataxia) to collapse and recumbency where horses are unable to stand.

The incubation period of the virus is on average 4-7 days but can be as little as 24 hours or as much as 14+ days. The virus can last up to a month in the environment once it has been shed but it can be killed easily by virucidal disinfectants.

Should you vaccinate your horses against EHV?

There is a vaccine available for EHV1-4 that can help reduce nasal shedding of the virus if a vaccinated horse becomes infected with the virus. This therefore means that it reduces the amount of virus shed into the environment, reducing the risk of other horses becoming infected, as well as offering that individual some protection against respiratory infection and abortion in the brood mare. A primary course is given (2 vaccinations 4-6 weeks apart) followed by 6 monthly boosters.

However, the vaccination does not offer full protection for respiratory disease and abortion ( as is the case for most vaccines) and does NOT protect against the neurological form of disease. It is also advised to NOT VACCINATE any horse that is thought to have been in contact with EHV-1 or may come in to contact with it e.g. travelling to a show in Europe in the near future whilst the EHV 1 outbreak is still being managed, as there is a possibility that vaccination could exacerbate and increase the risk of neurological signs.

As long as there is no risk of recent exposure, we recommend the routine vaccination of :-Pregnant mares at 5, 7 and 9 months of pregnancy to reduce the risk of abortion.

We also recommend the routine vaccination of:-

-Horses kept in close proximity to pregnant mares

-Young stock

-Horses who travel a lot to compete or move to different properties regularly. Ideally their stable mates would also be vaccinated as a “herd”/yard cover.


Good biosecurity, such as quarantining new arrivals/ use of disinfectants/footbaths/ PPE and nominated grooms for quarantined horses etc remains key in trying to reduce the spread of EHV.

We also advise clients to go to the following link to the HBLB Code of Practice to find all detailed information regarding EHV

EHV Update 14.01.2020

Following the outbreak of EHV-1 infection at Crofton Manor Equestrian Centre, the practices and veterinary surgeons involved in the outbreak collectively discussed appropriate planning and continue to be in frequent contact ensuring collective awareness of the situation at Crofton and elsewhere. Inevitably situations such as this can generate misunderstandings and rumours so we thought it was worth issuing this collective post which outlines the approach agreed upon by practices looking after horses in the local area including Animed Equine VetsKings Bounty Equine PracticeThe Liphook Equine HospitalRiverside Vets Equine and Stable Close Equine Practice, in conjunction with Dr Richard Newton, Director of Epidemiology and Disease Surveillance at the Animal Health Trust.

We are considering horses to be in 1 of 3 levels of risk and should be treated accordingly:

A) Highest Risk – Horses stabled at Crofton Manor Equestrian Centre are subject to the strictest protocols with isolation, frequent clinical checks and also swabs and blood samples. This will be ongoing until they are found to no longer pose an infectious threat and normal activities can safely resume.

B) Intermediate Risk – Horses that have visited Crofton Manor Equestrian Centre at some time since 21st December 2019 along with their stablemates at their home yards. The horse or horses that visited Crofton should be kept isolated from others and also subject to clinical checks, swabs and blood samples. Movement of all other horses from the yard should also be restricted as they may have been exposed to the virus and may themselves act as a source of ongoing infection. As long as all remains well on these yards and test results are reassuring then we would expect movement restrictions to be no longer than 2 weeks since the date of the visit to Crofton. Where the two weeks since the date of the visit to Crofton has already elapsed, to be safe we still strongly advise clearance of animals that attended Crofton based on swab and blood testing.

C) Low Risk – Horses that have not visited Crofton or had contact with horses that have visited Crofton can continue to be managed as normal alongside increased vigilance of their health status (e.g. appetite, behaviour etc…).

Clearly advice could change in the future pending further developments and test results but so far we have had no evidence of EHV-related disease outside of Crofton.

Introducing our new Joint Supplement Elite!

Introducing our new Joint Supplement Elite for the nutritional maintenance of healthy cartilage in the joints of horses in training and competition work.

This supplement differs from our original joint supplement because it contains other beneficial ingredients alongside the concentrated form of Glucosamine hydrochloride (99% pure) as seen in our original joint supplement.  The other ingredients include Boswelia Serrata, a readily available herb with anti-inflammatory properties and Chondroitin Sulphate, Hyaluronic Acid and MSM – ingredients that are reported to have chondroprotective effects. The combination of these ingredients reportedly provides increased anti-inflammatory effects and chondroprotective effects compared to glucosamine alone.

The joint supplement elite is highly concentrated and can last up to 365 days depending on the size of your horse/ pony and level of activity they do. 

Please contact the practice if you would like any further information – we can help you work out a daily cost for your horse.

Equine Influenza July 2019 – Vigilance and Vaccination!

Sadly the equine industry is still experiencing high numbers of equine influenza cases, with June reported to have identified over a third of the total cases diagnosed this year. Our advice is to continue to vaccinate your horse every 6 months ( based on the fact that protective antibody levels start to wane after this period)….and be vigilant. Please call the practice if you have a horse showing any of the previously posted symptoms.

Further advice has been published by the Animal Health Trust which you can access HERE. If you compete then an easy to follow fun guide has been produced – CLICK HERE! We are here if you need us….

Zoetis Shoot.

There has been an increasing number of equine influenza cases in the UK in recent months, some of which have affected TB racing yards – race meetings have now been cancelled by the BHA. The BEF are closely monitoring the situation but at the time of this post (08.02.19) is not recommending the cancellation of other equine events at present – this will be under constant review.

The H3N8 Florida Clade 1 influenza virus strain appears to be the recent strain involved in the UK. Not all UK equine ‘flu vaccine brands contain this strain but Kings Bounty have been using a vaccine brand containing this strain for the last 9 years (Proteq-flu).

No vaccine is ever 100% protective but it can minimise the severity of disease should a horse be infected. A horse’s immunity will lower towards the end of the period when the next booster is due and so, following guidelines received from the Animal Health Trust, we are recommending that horses who have not received a booster in the last 6 months, are given a vaccination as soon as possible.

Please contact the practice if you have any more concerns or would like to book in a vaccination. Please visit our Facebook page for posts / links to help you recognise signs/symptoms and for biosecurity tips.
