The first cases of West Nile virus have been confirmed in Minnesota, about a month later than usual. Mike McLean with Metropolitan Mosquito Control says West Nile cases are most common:

“Primarily from the Twin Cities west into the western part of the state and then into the Dakota’s as well. The types of mosquitoes that spread West Nile virus do really well in prairie areas.”

McLean says mosquitoes get the virus by feeding on infected birds.
