This year in Europe, 33 human West Nile virus (WNV) infections have been recorded, with the bulk of the cases seen in Greece.
Of the 25 WNV cases in Greece, 17 being neuroinvasive cases and two deaths. The two fatalities were over the age of 80.
West Nile virus (WNV) is most commonly spread to people by the bite of an infected mosquito. There are no vaccines to prevent or medications to treat WNV in people. Fortunately, most people infected with WNV do not feel sick. About 1 in 5 people who are infected develop a fever and other symptoms. About 1 out of 150 infected people develop a serious, sometimes fatal, illness.
