The number of horses who've died after an outbreak of a highly contagious equine herpes virus in Hampshire has risen to four.

The Crofton Manor Equestrian Centre, near Stubbington, has been in quarantine since the first case of EHV-1 was confirmed on Tuesday.

The centre has been praised for its quick action on social media, after it posted news of the outbreak on its Facebook page:

It is with regret, that we have to inform you that we have positive cases of EHV-1 (Equine Herpes Virus) here at Crofton Manor.

All horses at the Titchfield Road based centre, which hosts show jumping and dressage competitions, have now been tested.

Whilst the majority of the horses came back negative, ten horses tested positive for the virus which can cause inflation of blood vessels in the spinal cord and brain, but cannot be passed to humans.

Crofton Manor said they'd be following veterinary advice to remain in quarantine and will be following strict bio security procedures.

This will remain in place until 28 days after the last positive case.
