Bluetongue continues to advance in the UK, where over 3300 outbreaks have been confirmed since the start of the 2026-2027 season. The disease, also known as bluetongue, is caused by a virus that affects ruminants and is transmitted through the bite of small insects.
Now, faced with an increasingly widespread spread, Scotland has changed strategy, extending the restriction zone to the entire national territory and focusing on vaccination to protect itself from the most serious consequences of the infection.
The Bluetongue Epidemic in the UK
The numbers reflect the extent of the emergency. According to the latest update from the UK government, published on 12 October 2026, 3,338 outbreaks of Bluetongue have been confirmed in the UK in the current season: 2,812 in England, 478 in Wales and 48 in Scotland. The count concerns the farms or companies in which the presence of the virus has been confirmed, not the overall number of infected animals.
The serotype responsible for the current epidemic is mainly BTV-3, already identified in England in 2023. In the current season the spread has also reached Scotland, where the first cases affected the south-west of the country. The picture is constantly evolving and requires attention especially for cattle and sheep farms, among the species most exposed to the consequences of the disease.
But what is it exactly? Bluetongue, or bluetongue, is a viral disease that affects domestic and wild ruminants. It is not transmitted directly from one animal to another in normal coexistence, but above all through the bite of small blood-sucking insects of the genus Culicoides.
It can cause fever, lesions and inflammation, breathing difficulties and, in the most serious cases, death. The severity varies depending on the species, health situation and serotype involved.
All of Scotland is a restriction zone
From 3 October 2026 the restriction zone for Bluetongue has been extended to the whole of Scotland, whereas previously it only included some areas of the south west. The decision, agreed by the Scottish Government with organizations in the livestock sector, was born from a practical evaluation: the disease will not disappear soon and maintaining a delimited area in only one part of the country entailed additional procedures for the movement of animals.
What changes, concretely? With all of Scotland subject to the same health status, the specific movement licenses that were previously needed to move cattle, sheep and other sensitive ruminants into, within and out of the former South West zone are no longer required. The change should therefore facilitate livestock trade, reducing obligations for breeders, transporters and auction markets in view of the busy autumn season.
However, this is not a return to normality: animals showing clinical symptoms of Bluetongue cannot be moved, those affected by the disease must remain on farms for 60 days and specific restrictions continue to apply for transfers to Northern Ireland.
The choice involves a health compromise. Since the restriction zone was established in the south-west, the virus had been detected on 40 farms, four of which were outside the demarcated area, the cases having been identified by tracing the movements of animals from infected farms. Simplifying movements therefore means accepting a possible increase in the opportunities for the virus to spread, also relying on the seasonal reduction in the activity of Culicoides, the small insects that transmit it.
The animal protection strategy
Alongside the review of travel rules, Scottish authorities insist on the need to protect animals through vaccination. The government recommends that farmers consult their veterinarian to evaluate how to organize prophylaxis, taking into account the characteristics of the farm and the risk linked to the circulation of the virus.
NFU Scotland, the organization representing Scottish farmers, also supported the extension of the restriction zone, underlining the importance of making the movement of livestock easier without neglecting prevention. Vaccination is considered a fundamental tool for reducing the most serious consequences of BTV-3, but it does not offer an absolute guarantee against every infection.
The Scottish decision therefore reflects the need to reconcile two needs: on the one hand, to limit the economic and bureaucratic inconveniences for the livestock sector; on the other, containing the effects of an epidemic that has already reached significant numbers.
