The Shamonda virus was first detected in livestock in Great Britain

The Shamonda virus (SHAV), new to Europe and primarily transmitted by biting midges of the genus *Culicoides*, was detected in livestock across several European countries throughout 2026, including recent cases in cattle in Jersey and the Republic of Ireland. In October 2026, APHA specialists in Weybridge tested samples and confirmed the presence of SHAV in cows on two dairy farms — in Powys (Wales) and Shropshire (England).

Authorities note that this detection came as no surprise against the backdrop of reports from other European countries and confirms the effectiveness of surveillance and diagnostic systems. Since the Shamonda virus is not classified as a notifiable disease, the introduction of additional control measures is not currently required. At the same time, Defra, the Welsh Government, the Scottish Government, and APHA continue to monitor the epidemiological situation.

Livestock owners are advised to closely monitor the condition of their herds, promptly contact private veterinary surgeons if clinical signs appear, and provide symptomatic treatment. Veterinary professionals are encouraged to study the manifestations of the virus. To discuss diagnostic testing, one can contact local APHA Veterinary Investigation Centres, surveillance pathology partners in England and Wales, or SRUC.

The Food Standards Agency confirmed that there is no evidence to suggest the Shamonda virus poses a threat to food safety. Regarding human health, a single case of infection has thus far been reported in France in a patient with severe immunodeficiency. There is no data indicating a widespread transmission of the virus among humans, and UKHSA assesses the current risk to the general public as very low while continuing its monitoring efforts.
