Over the course of the current mosquito season, data from the European Centre for Disease Prevention and Control (ECDC) indicates that more than 240 cases of West Nile virus infection have been recorded across seven European nations. The ECDC reported that all documented infections were sustained through local transmission, confirming that no individuals contracted the virus while traveling abroad. Specific national data reveals significant regional variation.
Italy reported the highest number of infections with 139 cases, followed by Greece, which recorded 61 cases. Spain reported 17 cases, while North Macedonia accounted for 13. Other countries contributing to the total include Romania with six cases, France with four, and Germany, which registered one case in the Rhine-Palatinate district, though its total count, including imported instances, stands at five for the year.
The scope of the outbreak has been widespread, affecting 59 distinct areas across Europe—representing more than half of the continent’s monitored regions. This consistent surveillance highlights ongoing public health concerns regarding arboviral transmission. The consistent tracking of these cases underscores the necessity for vigilance against the spread of the West Nile virus across diverse European ecosystems.
