Crews will be spraying for mosquitoes around Governor John Sevier Highway beginning Sunday night at 9:00.
This will affect neighborhoods near Kimberlin Heights Road and Chapman Highway.
The Knox County Health Department is spraying these areas because lab results confirmed the presence of the West Nile Virus in six different areas in the county, which is the highest in the county's history.
The county has sprayed four different areas on Thursday. The health department is advising everyone, including pets, to remain indoors while crews are spraying tonight.
