Horse shows in the Netherlands have been disrupted by an outbreak of the neurological strain of the equine herpes virus (EHV-1).
All equestrian competitions have been cancelled since the outbreak in eastern Holland at the end of February and had not restarted as H&H went to press.
And in the UK the Animal Health Trust is urging owners of in-foal mares who abort to have them investigated for the virus, which can cause abortions.
In January and February there were four cases of EHV-1 diagnosed in UK mares.
