(WBIR - KNOXVILLE) A second round of spraying for mosquitoes will take place, weather permitting, 9 p.m. to midnight Thursday in the Tower Drive area of North Knoxville.
The Knox County Health Department conducted an initial round of spraying Aug. 30 in the area.
Also, the West Hills and West Kingston Pike areas are scheduled for follow-up spraying 9 pm. to midnight Sept. 17.
The Health Department is asking residents in those areas to avoid going outside and keep pets indoors during spraying.
The Health Department only sprays when mosquitoes test positive in an area for the West Nile virus, which has been reported in several humans in Tennessee including Blount County.
West Nile can cause illness in humans, including fever.
Less than 1 percent of infected people develop a serious, sometimes fatal neurologic illness, according to the Centers for Disease Control and Prevention.
