Shamonda-like virus detected in livestock across Belgium and France

The Shamonda-like virus, a member of the orthobunyavirus family transmitted by Culicoides biting midges, has been confirmed in livestock across parts of Western Europe. In Belgium, the presence of the virus has been established in cattle and sheep within the Wallonia region, specifically in the provinces of Namur and Hainaut. While sheep have shown no clinical signs, affected cattle have exhibited fever, lethargy, acute diarrhea, and significant drops in milk production. Authorities are monitoring for potential complications such as abortions and congenital malformations.

In eastern France, including Savoie, Haute-Savoie, Ain, Jura, and Doubs, cattle farmers have reported similar symptoms since July. The virus has also been detected in Germany and Switzerland. Although the virus is not transmissible to humans and is not currently regulated by the World Organisation for Animal Health (WOAH), it is causing economic strain. Some dairy farmers have reported milk production losses of approximately 10% due to the infection.
