Seroprevalence of West Nile virus, Greece, 2020.

ABSTRACT: BackgroundWest Nile virus (WNV) is a growing public health concern in Europe. Greece is one of the most affected countries in Europe, with the highest annual incidences.AimWe aimed at assessing IgG antibodies to WNV in the Greek population and compared the results with a nationwide survey conducted in the period 2012-2013.MethodsIn a geographically stratified sampling, 4,416 serum samples were collected and analysed for WNV-specific IgG antibodies using ELISA. Samples positive for WNV IgG were further tested with a WNV serum neutralisation test to detect false positives.ResultsThe weighted seroprevalence, adjusted for age, sex and region, was 2.83% (95% confidence interval (CI): 2.32-3.44) in the 4,416 samples tested, significantly higher than in the 2012-2013 survey (1.55%; 95% CI: 1.17-2
