WNV infection generally causes no symptoms or just mild, flu-like symptoms, however, the elderly are at higher risk of more severe disease.

The virus was responsible for 62 human cases of encephalitis in New York State and seven deaths. Such measures include spraying insect repellent on their clothing and exposed skin in accordance with labeling directions and wearing long sleeved shirts and pants when outdoors.
