Knox County Tennessee

West Nile Virus Control Program

KCHD has a mosquito control program and as the weather begins to warm each spring, public health professionals begin trapping mosquitoes around the county and testing batches for West Nile Virus (WNV), a mosquito-borne disease which can infect humans, horses and birds.


Environmental investigations are conducted in response to complaints filed with the health department. Mosquito control technicians will investigate to determine if mosquito breeding is occurring. If larvae are found, a plan is developed and implemented to correct the issue.
