West Nile Virus Management Policy
The City of Fort Collins recognizes West Nile virus to be a public health issue. This West Nile Virus Management Policy has been developed to reduce the incidence of city residents contracting West Nile virus (a mosquito-borne virus). The overall goal of this policy is to reduce the risk of human West Nile virus infection while limiting adverse human health and environmental impacts.
The City applies adulticides only as an emergency response to a demonstrated increase in West Nile virus risk. A recommendation to adulticide comes from the Larimer County Department of Health and Environment and is review by a City-appointed West Nile Virus Advisory Panel, which provides separate comments to the City Manager. The decision to adulticide lies with the City Manager.
