Situation
A newly identified orthobunyavirus has been detected in diseased cattle in several Western European countries since June 2026.
Details
The virus is genetically related to both Schmallenberg virus (SBV) and Akabane virus. Read the BEACON report, Shamonda-like orthobunyavirus identified in eastern France.
The virus has also been detected in horses with neurological disease, as well as in sheep, goats and an alpaca.
Transmission is thought to occur primarily through the bites of infected Culicoides midges.
Affected cattle may develop fever, diarrhoea, lethargy, reduced milk production and mild respiratory signs. Abortions and congenital defects are possible, similar to Schmallenberg virus. There is no evidence of zoonotic transmission.
Further information
There is currently no evidence of infection in Great Britain, although there is potential for incursion from affected areas in Europe. Diagnostic testing is available at the Animal and Plant Health Agency (APHA). If you have livestock with suspected Shamonda-like virus infection, please contact your local Veterinary Investigation Centre for advice and further investigation.
