CHATTANOOGA, Tenn. (AP) -- Health officials in Chattanooga say routine testing has found West Nile virus in mosquitoes.
Two pools of mosquitoes in the southern part of Hamilton County have been found to be infected.
Hamilton County environmental program manager David Hunter says it's a signal that people need to use insect repellent when they're outdoors.
Hunter also says people should call the department if they see dead crows, robins and blue jays. Those species are the most vulnerable to West Nile virus.
There have been no confirmed cases of West Nile in humans in Hamilton County this year.
Officials say 80 percent of people infected with the virus show no symptoms, but under 1 percent will require hospitalization.
