2012 West Nile Virus Activity

The following maps and statistics show counties with West Nile virus activity. Human Case Map 1 shows counties where the infected person was most likely exposed; Map 2 shows counties where the infected person lives.

 

Ongoing West Nile virus monitoring for infected dead birds and mosquitoes is limited to a few counties due to a lack of resources. West Nile virus activity may not be indicated in your county; however, the virus is likely to be widespread in our state. Follow these easy prevention steps to protect yourself and family.
