Equine owners are being encouraged to be vigilant after a mare was hospitalised with neurological disease following infection with West Nile virus (WNV).
BEVA officials said rising temperatures mean more cases in the UK are possible, but have stressed there is no risk of onward spread.
The seven-year-old warmblood mare, which was unvaccinated against the virus, was diagnosed on 6 November, having returned to the UK from a competition in Spain.
It is believed the mare, which is now recovering at home, was infected in Spain and its condition worsened on returning to the UK.
