Defra said there have been 320 cases of bluetongue in Great Britain in the 2025 bluetongue season (since July 1, 2025). In:
- England, there have been 298 cases of bluetongue – including 289 cases of only BTV-3, two cases of only BTV-8 and seven cases with both BTV-3 and BTV-8;
- Wales, there have been 22 cases of BTV-3.
There have been no cases in Scotland.
The location of all premises in Great Britain where one or more animals have tested positive by PCR for bluetongue serotype 3, serotype 8 or serotype 12 is available on the bluetongue case map.
There are five confirmed cases of BTV-3 in Northern Ireland.
Two new cases of BTV-3 in England were confirmed on March 9, 2026, following a report of suspicious clinical signs:
- One calf in Devon born with neurological signs, calf is unwilling to suck and has slight discolouration of nose; and
- One calf in Cheshire born with neurological signs and one cow (dam of the calf) tested positive.
Risk level
Temperatures remain low, and experts consider the risk of onward spread by vectors in England to be negligible. There is however still a risk that animals can get infected from infected germinal products.
The risk of incursion of bluetongue virus (including serotypes not currently circulating in England) from all routes remains at medium (occurs regularly) although the risk of airborne incursion is now negligible.
