Global Epidemiology of West Nile Virus
West Nile Virus (WNV) is a worldwide concern, with its impact varying across different regions. Understanding the global epidemiology of WNV is crucial to comprehend its prevalence and preventive measures better.
2023 US West Nile Virus Detection
Syracuse, Utah, had an unexpected visitor in 2023. The West Nile Virus was detected in a local mosquito pool, as confirmed by the Davis Mosquito Abatement District. This revelation marked the first indication of the virus’s circulation in the community.
Fortunately, no human cases of WNV have been reported in Utah thus far. However, the United States has seen 36 reported cases this year, with Arizona taking the lead at 25 cases.
Global Epidemiology
WNV has an extensive history, being first isolated in a woman in the West Nile district of Uganda in 1937.
It’s known to cause outbreaks in regions on major bird migratory routes, with the largest ones recorded in Greece, Israel, Romania, Russia, and the USA. Introduced in the USA in 1999, WNV has since spread across the continent.
In temperate climates like the United States and Europe, the peak season for WNV infection ranges from July to October, although warmer and humid climates may experience extended peak seasons.
Everyone is susceptible to WNV, but individuals aged 60-89 years old have a higher risk of severe disease.
Although mosquitoes are the primary vectors, rare cases of WNV transmission have been reported through organ transplantation, blood transfusion, breastfeeding, transplacental transmission, and laboratory acquisition.
As the climate continues to change, expect the global distribution of WNV to continue to push northwards and southwards. No longer a solely African disease, it is set become a truly universal condition.
