Details

Equine viral arteritis (EVA) is occasionally detected in the UK in stallions which are tested for pre-breeding or for export purposes.

Under the EVA Order (1995) the disease is only notifiable in stallions and in mares which have been mated or inseminated in the past 14 days.

Dorset and Devon, March and April 2019

APHA has confirmed equine arteritis virus (EAV) infection by PCR testing of semen samples taken from:

• 3 non-thoroughbred dressage stallions on a premise in Dorset
• a single stallion on a premise in Devon

Shropshire, July 2019

APHA has confirmed EAV infection by PCR testing of a semen sample taken from a pony stallion on a premise in Shropshire. The infection was initially discovered by routine private pre-breeding ELISA-based serology testing.

There is no evidence to suggest a connection between the Shropshire case, and the Devon and Dorset cases. The owner has castrated the stallion to make sure there’s no risk of EVA spreading through future breeding activities.
