Cantabria detects first case of Shamonda virus in livestock

The first case of the Shamonda virus has been detected in Cantabria, Spain, specifically at a livestock farm in the municipality of Riotuerto. The detection was confirmed by the Central Veterinary Laboratory of Algete.

Transmitted by Culicoides insects, the virus primarily affects cattle, causing symptoms such as fever, diarrhea, lethargy, and reduced milk production. While it can affect sheep, goats, and horses, these species typically remain asymptomatic. Although mortality rates are low and the disease does not require animal culling, it can cause significant economic impacts due to decreased productivity, particularly in dairy farming.

Authorities have clarified that the virus is not zoonotic, meaning there is no evidence of transmission to humans through direct contact or consumption of animal products. Because the virus is spread by insect vectors rather than direct animal-to-animal contact, livestock fairs and events are not expected to be affected. Currently, there is no specific vaccine available. Recommended preventive measures include insect control, disinfection of transport, and managing standing water and manure to reduce insect populations.
