Seroprevalence data indicate that West Nile virus (WNV) activity is present in Turkey; however, no pediatric cases of WNV infection have been reported to date. WNV is an emerging flavivirus in Turkey, and in September2010, the Turkish Ministry of Health reported the first seven cases of laboratory-confirmed WNV infection from five different cities in the western part of the country. This is the first report of a child from central Anatolia, indicating the existence of the virus in other regions of the country.
