West Nile virus is a re-emerging arbovirus whose impact on public health is increasingly important as more and more epidemics and epizootics occur, particularly in America and Europe, with evidence of active circulation in Africa. Because birds constitute the main reservoirs, migratory movements allow the diffusion of various lineages in the world. It is therefore crucial to properly control the dispersion of these lineages, especially because some have a greater health impact on public health than others. This work describes the development and validation of a novel whole-genome amplicon-based sequencing approach to West Nile virus. This study was carried out on different strains from lineage 1 and 2 from Senegal and Italy. The presented protocol/approach showed good coverage using samples derived from several vertebrate hosts and may be valuable for West Nile genomic surveillance.

: West Nile virus (WNV) is a rapidly growing problem worldwide. The lack of emergency treatment and a safe licensed vaccine against WNV allows the virus to cause sporadic outbreaks of human disease, including fatal cases. Formalin-inactivated vaccines have been used for a long time and have been shown to be very safe and effective, especially in susceptible populations.

West Nile Virus (WNV) is a zoonotic, vector-borne pathogen affecting humans and animals, particularly in Europe. The virus is primarily transmitted through mosquitoes that infect birds, which serve as the main reservoirs. Humans and horses are incidental hosts.

The West Nile virus (WNV) has recently become more widespread, posing a threat to both human and animal health. In Western Europe, most outbreaks have been caused by WNV lineage 1, while in Eastern Europe, WNV lineage 2 has led to human and bird mortality. The ability to appropriately manage this threat is dependent on integrated surveillance and early detection.

Background: West Nile Virus [WNV] is a mosquito-borne flavivirus. It has spread globally, causing asymptomatic to severe neurological diseases in humans, with an increased risk in older adults and those with underlying conditions. This review examines WNV's impact on pregnancy, focusing on maternal and neonatal symptoms and risks.

Background: West Nile virus (WNV), although underdiagnosed, is the most common mosquito-borne disease and the second most common cause of viral encephalitis in the United States. Fewer than 1% of those infected develop neuroinvasive disease.
Methods: We present a cluster of 3 cases of neuroinvasive WNV that occurred between August and September 2023 and a review of the literature for neurologic involvement with this virus.
