The number of human cases of West Nile Virus continues to increase, and the U.S. is facing one of the worst outbreaks of the illness in years.
The Tennessee Health Department reports three confirmed cases of West Nile-- two in Shelby County and one in Greene County. None of those cases have been fatal.
But in Dallas County, Texas, health officials confirm eight people have died of the disease and they've taken reports totaling more than 120 cases.
