Livestock keepers urged to be on high alert and consider vaccination as Bluetongue cases rise

The UK Chief Veterinary Officer has issued an urgent call for livestock keepers to remain on high alert due to the increasing prevalence of the Bluetongue virus (BTV-3). Cases are rising, particularly in the Southwest of England and parts of Wales, largely driven by recent hot and humid weather conditions. These conditions have facilitated the rapid spread of biting midges, the primary vectors for the virus, creating a mounting challenge for the agricultural sector and veterinary professionals alike.

Bluetongue is a significant threat to various species, including sheep, cattle, goats, deer, and camelids like llamas and alpacas. Sheep are particularly susceptible to higher mortality rates. Common clinical signs of infection include high fever, lameness, significant swelling of the head and tongue, oral ulcers, respiratory distress, decreased milk production, and in severe cases, abortion or stillbirths. Expert consensus strongly favors vaccination as the primary defense, noting that even herds and flocks in areas where the disease is already present can benefit from the protection provided by vaccines.

To address this, the UK Government, through the Department for Environment, Food & Rural Affairs (Defra) and the Veterinary Medicines Directorate (VMD), has authorized three BTV-3 vaccines for use across Great Britain. Proactive measures have been taken to secure additional supplies to meet the high demand. Farmers and private veterinarians are strongly encouraged to order their vaccine supplies promptly to ensure timely protection for their livestock populations.

Chief Veterinary Officer Christine Middlemiss highlighted that vaccination is the most effective tool available to manage the welfare and business impacts of the outbreak. She urged producers to consult their vets immediately, noting that immunity development takes time. Farming Minister Stephen Morgan reiterated the government's commitment to monitoring the situation closely and working alongside industry stakeholders to respond as effectively as possible to the ongoing health threat.

Currently, the Animal and Plant Health Agency (APHA) and the Pirbright Institute are processing a high volume of diagnostic samples. To facilitate rapid results, veterinarians are advised to ensure all documentation and sample identification are accurate. While movement controls within England and Wales have been relaxed, restrictions on movements between UK nations remain in effect. Keepers are mandated to keep their registration details updated, perform regular health checks on their animals, and report any suspicions of the disease immediately to ensure appropriate containment and support.
