Bluetongue virus cases rise across the United Kingdom

The number of bluetongue virus cases is rising across the United Kingdom, with significant impacts reported on livestock and farmer mental health. In Wales, the first case of Bluetongue virus serotype 3 (BTV-3) for the 2026/27 season has been confirmed in the Vale of Glamorgan. CLA Cymru has urged livestock farmers to remain vigilant, noting that high midge activity following hot, dry weather has created favorable conditions for the spread of the disease.

Across the UK, nearly 500 cases have been recorded, with substantial numbers in South-west England, including Devon and Cornwall. The virus, which is spread by biting midges, can cause lethargy, lameness, birth defects, and death in cattle, sheep, and goats.

Farmers have reported significant emotional and financial distress due to animal losses. Some producers have noted the high cost of vaccination and the psychological toll of managing large numbers of sick animals, with some expressing concerns regarding long-term mental health impacts similar to those seen during previous agricultural crises.
