The genomic epidemiology of West Nile virus (WNV) in Europe provides valuable insights into the dynamics of virus transmission, evolution, and spread within the continent. WNV, a mosquito-borne flavivirus belonging to the Flaviviridae family, is known to cause febrile illness, neurological disease, and fatalities in humans and animals. While historically endemic to Africa, Asia, and parts of the Middle East, the emergence of WNV in Europe over the past two decades has raised concerns about its public health impact and the factors driving its spread across the continent. Genomic epidemiology, which integrates genomic sequencing and phylogenetic analysis with epidemiological data, has emerged as a powerful tool for tracking the transmission dynamics of WNV and elucidating its genetic diversity and evolution. By sequencing viral genomes from human and animal cases, as well as mosquito vectors, researchers can reconstruct the phylogenetic relationships between different WNV strains and infer their geographic origins and transmission routes.
Studies on the genomic epidemiology of WNV in Europe have revealed the presence of multiple genetic lineages and genotypes circulating within the continent, reflecting the complex interplay between viral evolution and ecological factors such as vector distribution, bird migration, and climate variability. Phylogenetic analysis of WNV genomes has identified distinct clusters associated with specific regions or countries, indicating localized transmission and endemic circulation of the virus in Europe. One of the key findings from genomic epidemiological studies is the role of migratory birds in the introduction and spread of WNV across Europe. Molecular characterization of WNV strains has identified genetic variants closely related to strains circulating in Africa and the Middle East, suggesting that migratory birds serve as reservoir hosts and vectors for introducing WNV into Europe during their seasonal migrations. Furthermore, genomic analysis has revealed genetic signatures associated with viral adaptation to local mosquito vectors and amplification hosts, facilitating sustained transmission cycles within Europe. The genomic epidemiology of WNV in Europe also provides insights into the factors driving the emergence and spread of the virus in new geographic regions. Climate change, land use changes, and globalization have been implicated in the expansion of WNV transmission zones and the emergence of outbreaks in previously unaffected areas. By combining genomic data with environmental and epidemiological factors, researchers can identify high-risk regions and populations susceptible to WNV infection, informing targeted surveillance and control strategies to mitigate the public health impact of the virus. Moreover, genomic surveillance of WNV is instrumental in monitoring the emergence of novel genetic variants with increased virulence or altered transmission dynamics. Genomic sequencing allows for the rapid detection of mutations associated with phenotypic changes in viral fitness, drug resistance, or immune evasion, providing early warning signals for potential shifts in WNV epidemiology and the emergence of new public health threats.
The genomic epidemiology of West Nile virus in Europe offers valuable insights into the transmission dynamics, genetic diversity, and evolution of the virus within the continent. By integrating genomic sequencing with epidemiological and ecological data, researchers can elucidate the factors driving the emergence and spread of WNV, inform targeted surveillance and control efforts, and enhance our understanding of the dynamics of arbovirus transmission in a changing world.
