Abstract:
In 2024, Andalusia (Southern Spain) reported its largest recent West Nile virus (WNV) outbreak, with 106 confirmed human cases and 16 deaths. Genomic analysis of 27 WNV isolates revealed the co-circulation of multiple WNV lineage 1 clades, including both endemic and recently introduced strains, reflecting a marked increase in viral genetic diversity. These findings underscore the critical role of integrated genomic surveillance systems in monitoring pathogen evolution and supporting timely public health responses to emerging zoonotic threats.
