Bluetongue virus outbreak impacts livestock in England and Wales

A significant outbreak of the Bluetongue virus (BTV-3) is spreading through England and Wales, causing high mortality rates in sheep and severe illness in cattle. The disease is transmitted by biting midges, which are increasingly spreading due to changing climate patterns and warmer summers.

In the south-west of England, the impact has been particularly heavy, with Department for Environment, Food and Rural Affairs (Defra) data showing 202 affected sites in Devon and 77 in Cornwall. Farmers have reported sudden deaths in flocks and symptoms such as severe nasal discharge and mouth sores.

To manage the crisis, experts recommend vaccination and movement restrictions for susceptible livestock. However, vaccination is placing a significant financial burden on the agricultural sector. The Association of Drainage Authorities (ADA) and other industry bodies are advising farmers to manage damp soil and organic matter to reduce midge breeding sites.
