The Shamonda virus (SHAV), an emerging virus in Europe primarily spread by biting midges, has been detected in livestock in Great Britain for the first time, with cases confirmed in cattle in Powys, Wales, and Shropshire, England.

The virus was identified after samples were collected and tested at APHA laboratories in Weybridge. This detection follows recent reports of SHAV in cattle in Jersey and the Republic of Ireland earlier in 2026. The detection demonstrates the effectiveness of the UK's surveillance and diagnostic systems in identifying new and emerging diseases.
SHAV is not a notifiable or reportable disease, and currently, no additional disease-control measures are deemed necessary. However, Defra, the Welsh Government, Scottish Government, and the APHA will continue to monitor the epidemiological situation and review the response as further evidence becomes available.
Livestock keepers are advised to continue monitoring their animals for clinical signs and to contact their private veterinarian if they have concerns. Veterinarians are encouraged to familiarise themselves with the clinical signs associated with SHAV. For diagnostic investigation, contact the local APHA Veterinary Investigation Centre (VIC) or a Surveillance Pathology Partner.
A single human case of Shamonda virus infection has been identified in a severely immunosuppressed individual in France. However, there is currently no evidence of wider transmission among humans, and the risk to the general population is considered very low. The UKHSA is monitoring the situation closely. The Food Standards Agency has confirmed there is no evidence that Shamonda virus poses a food safety risk.
