West Nile Virus Increase in Black Hawk County


Ongoing mosquito surveillance efforts have indicated that Black Hawk County is currently experiencing increased levels of West Nile Virus within the adult mosquito population, raising the potential for human cases. This is part of a seasonal peak of West Nile Virus transmission in the county and further samples are expected to test positive.


To reduce risk of mosquito bites people are encouraged to:

·      Take extra precaution between dawn and dusk when mosquitos are most active.

·      Wear insect repellent and protective clothing during outdoor activities.

·      Take the necessary steps to prevent mosquito harborage on and around their homes.


To reduce potential mosquito breeding reservoirs and harborages around the home, take the following preventative steps:

·      Remove or turn over containers, buckets, wheelbarrows, etc. that may accumulate water.

·      Dispose of any used tires to prevent water accumulation.

·      Change water in bird baths, wading pools least once a week.

·      Clean rain gutters and downspouts to prevent standing water.

·      Cover rain barrels and unchlorinated pools to prevent mosquito access.


It is important to remain diligent when it comes to protecting yourself, your family, and the community from West Nile and other mosquito borne illnesses.
