[West Nile virus infection: an emerging arbovirosis in France and Europe].

Abstract : West nile virus infection: an emerging arbovirosis in france and europe. West Nile virus is a mosquito-borne flavivirus, transmitted to humans by mosquitoes of the genus Culex, from an avian reservoir. Humans are accidental hosts and there is no report of human-to-human transmission, except via blood transfusion or organ transplantation. In 2018, Europe experienced the largest outbreak of West Nile virus infection ever. In France, 27 cases were identified including 7 neuro invasive forms. This infection is asymptomatic in most cases but may also manifest as an isolated fever or flu-like syndrome. In about 1% of cases, neuro-invasive forms with meningitis, meningoencephalitis or flaccid paralysis can be observed. There is no specific treatment for this viral infection. Prevention is based on the prevention of mosquito bites, but also on enhanced epidemiological surveillance during the period of circulation of the virus in Europe (from spring to autumn).
