West Nile Virus - Wisconsin
Cumulative Bird Map
These county and county - equivalent data are based on tests of tissue samples from
dead and diseased wild birds, provided by state health officials. Many of these
data represent crows, which are especially sensitive to West Nile Virus (WNV).
Note that the map includes all areas of positive (confirmed or probable) WNV
results, but not necessarily all areas with submitted samples or no reports.
| Note: These data are provisional and may be revised or adjusted in the
future |
