Maps follow reemergence of West Nile Virus

The West Nile Virus has been slower to appear in Wisconsin than last summer, but some cases in the last few weeks have brought the story into the popular press.

Maps showing testing as well as positive identifications are available on the web. See link below.

On a national scale, the virus appears to have begun to affect states to our west, continuing the westward trend of several years now.
