West Nile virus continues to be a threat in northern Illinois.

The temperature may be cooling off, but you'll still want to keep an eye on those mosquitoes. Winnebago County officials confirmed this week that a bird tested positive for West Nile virus. It's the 13th year in a row the virus has been confirmed in the county. The infected bird was found much later than last year.
