Shamonda virus detected in cattle across Germany

The Shamonda virus, a novel pathogen from the Orthobunyavirus group, has been detected in cattle in Saxony, marking its first appearance in the region. This follows recent outbreaks in southern Germany, Switzerland, and eastern France. A cow in the Vogtland district tested positive, with the findings confirmed by the Friedrich-Loeffler-Institut (FLI). Another suspected case has been reported in the Erzgebirge region.

In Bavaria, specifically the Dachau district, the virus has spread significantly, with reports indicating that 80 to 90 percent of dairy farms in the area are affected. Symptoms in infected cattle include fever, diarrhea, and a significant decrease in milk production. There are concerns among farmers regarding potential deformities in offspring, similar to those seen with the Schmallenberg virus.

The virus is transmitted to cattle by biting insects such as midges and mosquitoes. Current weather conditions, characterized by mild temperatures and high humidity, may facilitate the spread of the virus between herds. Currently, there is no vaccine available, and farmers are relying on insect repellents to mitigate the risk of transmission.
