2022 WNV Grants

Nearly 200 South Dakota cities, counties and tribes will share $500,000 in grants intended to control mosquitoes and prevent West Nile virus (WNV) in 2022. All applying communities received funding with grants ranging from $500 to $20,000. Grant awards were based on the population of the applying jurisdiction and its history of human WNV cases through 2021.
