UK Hit by Record 2,201 Bluetongue Cases
The worst ever outbreak of the viral disease has surpassed the past three years combined, with 1,103 cases recorded in September alone, and has spread to Scotland for the first time
The UK is experiencing its worst bluetongue season on record, with 2,201 cases reported so far. This surpasses the total number of cases from the past three years combined. The 2026-27 bluetongue season, which runs from 1 July 2026 to 30 June 2027, has seen a significant spike in cases, with 1,103 recorded in September alone.
The disease, which affects sheep and cattle, has spread to Scotland for the first time, with cases found as far north as Aberdeenshire. According to Defra, a case is defined as a premises where at least one animal with bluetongue is present, so the total number of animals affected is likely to be higher than the number of reported cases.
Bluetongue serotype 3 (BTV-3) was first found in England in 2023, and the World Organisation for Animal Health links the spread of the disease to climate breakdown. The virus is transmitted via biting midges, and hotter temperatures contribute to the rise in cases. Academics have said that the transmission is inextricably linked to the temperature of the surrounding environment.
## Why it matters The outbreak has significant implications for British farmers, who are having to keep constant vigilance and continually check their livestock for symptoms. While bluetongue does not affect people or food safety, it can cause significant economic losses for farmers. The National Farmers’ Union has reported that it has been challenging for farmers to get hold of vaccines, as it is a demand-led process.
The spread of bluetongue to Scotland for the first time is a concern for farmers, and the record number of cases is a wake-up call for the industry. As the climate crisis continues to contribute to the rise in cases, farmers will need to take extra precautions to protect their livestock. The UK government and farming industry will need to work together to find solutions to mitigate the impact of the disease and support farmers affected by the outbreak.
## What happens next As the 2026-27 bluetongue season continues, farmers will need to remain vigilant and take steps to protect their livestock. The government and industry will need to work together to ensure that vaccines are available and that farmers have the support they need to deal with the outbreak. The spread of bluetongue to Scotland is a significant development, and it will be important to monitor the situation closely to prevent further spread of the disease.
