New cattle virus spreads across Europe; Slovenia reports no cases

A novel virus affecting cattle is spreading through Europe, with confirmed cases now reported in Germany, Switzerland, and France. The virus, identified as belonging to the Simbu group of orthobunyaviruses, is transmitted by biting midges, whose increased activity is likely linked to favorable climatic conditions.

In affected animals, symptoms include elevated body temperature, diarrhea, reduced appetite, and a temporary decrease in milk production. High-producing dairy cows appear to be particularly susceptible due to production stress and heat stress, making them more vulnerable to various diseases. However, the virus poses no risk to human health and is not subject to mandatory reporting or control measures by the European Union or the World Organisation for Animal Health (WOAH).

Slovenia has not yet recorded any cases of this new virus. The Slovenian Administration for Food Safety, Veterinary Sector and Plant Protection (UVHVVR) is urging cattle farmers to consistently implement biosecurity measures and exercise caution when purchasing new animals. Farmers are advised to immediately notify a veterinarian if any health issues arise within their herds.

While the current data does not indicate a significant risk to Slovenian livestock, authorities are closely monitoring the situation. They are exchanging information with other EU member states and international scientific bodies. Entomological surveillance of Culicoides midges and monitoring their distribution are underway in Slovenia to detect potential risks early. Diagnostic tests are also being conducted for other diseases transmitted by the same vectors.
