UK sees surge in Bluetongue (BTV-3) cases across England and Wales

In July 2026 the United Kingdom recorded 84 new Bluetongue virus (BTV‑3) outbreaks, far exceeding the same period last year. Defra confirmed 81 cases in England and three in Wales, while Scotland and Northern Ireland reported none. The current season has already surpassed the total number of cases from the previous year, indicating a rapid acceleration of the disease.

Veterinary authorities are urging livestock keepers to tighten biosecurity. The Welsh Government and the Animal and Plant Health Agency (APHA) advise checking the Bluetongue status of any replacement animals, consulting veterinarians about vaccination, and promptly reporting suspected cases. Wales’ Chief Veterinary Officer Richard Irvine highlighted that the all‑Wales Restricted Zone, introduced in November 2025, now allows unrestricted movement of livestock between England and Wales, heightening the need for vigilance.

Officials stress that vaccination remains the most effective protection for cattle and sheep herds, and they have provided resources through the Bluetongue Virus Hub to help farmers identify signs of the disease and implement preventive measures.
