Defra confirmed one new case of BTV-3 in England on 10 July 2026. The infection was found in a single ewe in Staffordshire. Clinical signs included head swelling, drooling, crusty nostrils and lameness on all four feet.
This marks the first confirmed case of the 2026-2027 season. Midge activity resumed on 31 March 2026. Cumulative temperatures have now reached levels that permit onward virus transmission by the Culicoides vectors.
The 2025-2026 season produced 348 cases of bluetongue across Great Britain since 1 July 2025. England accounted for 324 of those, with 311 involving only BTV-3, five only BTV-8, seven both serotypes and one of unknown type. Wales recorded 24 cases of BTV-3. Scotland saw none. Northern Ireland reported five cases of BTV-3.
The pattern is clear. After limited incursions in 2023-2024, case numbers climbed through subsequent vector seasons. Each year has demonstrated the vulnerability of UK ruminant herds once midges become active and temperatures allow the virus to spread.
The whole of England remains under a restricted zone. Movements of animals are permitted internally without licence or testing. Licences and testing are still required for germinal products. The current risk level of further incursion stands at medium.
Biosecurity and market-led protection
Bluetongue presents no risk to public health and does not compromise the safety of meat or milk. Control nevertheless carries direct economic consequences for farmers and rural communities already strained by previous outbreaks. Vaccination against BTV-3 is available through private purchase under licence. No cross-protection exists for BTV-8. This private market mechanism allows farmers to act on their own assessment of risk rather than await central mandates.
