Bluetongue virus (BTV) cases are increasing, with the clinical signs seen this month appearing more severe than in previous years. Since the start of the 2026/27 vector season on 1 July, BTV has been confirmed on 12 farms in England and one in Wales. Reported cases have included sudden deaths in sheep and high numbers of abortions in cattle herds.
Clinical signs can vary, so livestock keepers are urged to remain vigilant, know the signs and immediately report any suspicions of disease to the Animal and Plant Health Agency (APHA). Defra is funding the cost of diagnostic testing for up to three affected animals.
BTV can also be transmitted between animals through contaminated needles. Good hygiene practices should therefore be followed when treating or vaccinating animals to minimise the risk of transmission within your flock or herd.
