Database of present and future situation of West Nile virus in the Afro-Palaearctic Pathogeographic System

West Nile virus (WNV) is a globally widespread arthropod-borne virus that poses a significant public health concern. Mosquitoes transmit the virus in an enzootic cycle among birds, which act as reservoirs. Climate plays a crucial role in these outbreaks as mosquitoes are highly influenced by climatic conditions, and bird migrations are also affected by weather patterns. Consequently, changes in climate can potentially impact the occurrence of WNV outbreaks. We used biogeographic modelling based on machine learning algorithms and fuzzy logic to analyse and evaluate separately the risk of WNV outbreaks in two different biogeographic regions, the Afrotropical and the Western Palaearctic region. By employing fuzzy logic tools, we constructed a comprehensive risk model that integrates the Afro-Palaearctic system as a unified operational unit for WNV spread. This innovative approach recognizes the Afro-Palaearctic region as a pathogeographic system, characterized by biannual connections facil..., , , # Database of Present and future situation of West Nile virus in the Afro-Palaearctic Pathogeographic System

Dataset containing all the records and variables to elaborate the risk models of West Nile virus infection in the Afro-Palaearctic system. The dataset also contains the the result of the models in favourability values.

## Description of the data and file structure

The database is an Excel file where all the information regarding the distribution records of West Nile virus infection cases in Africa and Europe has been compiled, encompassing the Afro-palearctic system.

The field identifier for each Operational Geographic Unit (OGU) is the column HEX10_ID. The \"Region\" column displays each biogeographic region: \"ETIO\" for the Afrotropical region and \"PAL\" for the Palearctic region. \"Continent\" refers to the African (\"AF\") and European (\"EU\") continents. In the database can be seen the mean values...
