John McEwen, Director of Equine Sports Science & Medicine at the British Equestrian Federation's (BEF) World Class Programmes, has sent the following note to all the riders on the Programmes: 

Dear World Class Programme rider,

EQUINE HERPES EHV1 AND EHV4   

As you may be aware there has been an increase in the reported cases of Equine Herpes both EHV1 and EHV4, particularly in France and the UK, but also we expect elsewhere in Europe.

Equine herpes virus can have serious performance consequences and within the World Class Programme, we feel that owners and riders should be aware of the increased risk to travelling horses, in particular in Europe. We suggest that riders should consider talking to and taking advice from their home Vet regarding vaccination, if you have not already done so. If you or your Home Vet have any concerns please do not hesitate to contact the World Class Programme Vet connected to your programme / discipline.

It may also be prudent to discuss vaccination for West Nile if you are intending to compete in Europe on a regular basis.
