Shamonda virus (SHAV), a midge-borne virus closely related to Schmallenberg virus (SBV), has been detected in Great Britain for the first time following confirmation by the Animal and Plant Health Agency (APHA) on 2nd November 2026.
The virus has been identified in cattle on two dairy farms: one in Powys, Wales, and one in Shropshire, England.
Clinical signs may include:
• Diarrhoea
• High temperatures
• Sudden drop in milk yield
• Lethargy and reduced rumination
• Fertility issues
• Congenital abnormalities in calves or lambs
SHAV is not currently a notifiable disease, and no additional movement restrictions or control measures are required at this time.
However, its clinical signs can be very similar to those seen with other diseases, including Bluetongue, which remains a notifiable disease. Any suspicion of a notifiable disease must be reported to APHA immediately.
