The Shamonda virus, first detected in several European countries in August, has now arrived in Portugal. Transmitted by insects, the virus presents a significant threat to bovine populations, potentially causing abortions and fetal malformations. Authorities emphasize that the virus poses no risk to human health. The outbreak is currently being monitored to assess its extent and implement control measures. Farmers in Portugal are being advised to take preventative steps to protect their livestock from insect bites. This new viral presence adds to existing concerns regarding animal health within the European Union. Further investigation is underway to determine the origin and spread of the Shamonda virus within Portugal.
