West Nile Virus

West Nile virus (WNV) is an infectious disease agent that first appeared in the United States in 1999. WNV can result in an asymptomatic infection, a mild or moderate flu-like illness, or neurological diseases such as encephalitis or meningitis. Approximately 80 percent of people who are infected with WNV will show no symptoms at all. Typically people develop symptoms 3 to 14 days after they have been bitten by an infected mosquito.

Epidemiology Division, Field Surveillance Staff (FSS), investigate all reports of West Nile disease from notifiable disease reporters. ADPH displays the confirmed cases on the Alabama Mortality Report , Arbovirals, and submits it to CDC's ArboNet for display by county, see West Nile Alabama Cases links below. Case counts are updated weekly.
