Epidemiological Analysis of Rabies Outbreaks in the European Union and Türkiye (2013-2023)

Rabies is a fatal zoonotic viral disease that continues to pose a significant threat to both animal and public health worldwide. Despite considerable progress in its control across Europe, sporadic outbreaks still occur, particularly in regions where wildlife reservoirs and stray animal populations sustain virus circulation. This study provides one of the first comparative longitudinal analyses integrating European countries and Turkiye rabies surveillance data over a decade (2013-2023). Information on reported outbreaks was obtained from the Animal Disease Information System (ADIS) and the World Animal Health Information System (WAHIS) database. The analysis focused on temporal trends, regional differences, and the distribution of affected animal species. During the study period, a total of 4865 outbreaks were reported in 16 countries. The number of detected outbreaks declined considerably over time, decreasing from 1022 cases in 2013 to 325 cases in 2023, representing an overall reduction of approximately 68%. The temporal trend was not uniform, with periods of decline followed by temporary increases. The highest number of outbreaks was registered in Türkiye, followed by Romania and Poland, indicating pronounced regional disparities. Domestic dogs represented the most frequently affected species, while cases were also recorded in wildlife and domestic cats, confirming the epidemiological importance of both domestic and wild reservoirs. The observed reduction in the number of outbreaks reflects the impact of vaccination programs and coordinated control measures, but may also be influenced by differences in surveillance systems and reporting practices. Nevertheless, the persistence of rabies in several regions indicates that the disease remains an epidemiological concern. Sustained vaccination of domestic animals, continued wildlife immunization, and strengthened surveillance and cross-border cooperation are essential for long-term control and prevention.
