There are no human cases yet, but there has been an increase in what's called "West Nile Virus activity" in the Illinois Quad Cities. Monday the Rock Island County Health Department reported a significant increase in the number of moquitoes testing positive for the virus in traps in Moline and Rock Island.
In addition, a dead Blue Jay found in Rock Island tested positive.
The health department says it's normal for cases of West Nile Virus to peak in late summer, but also normal for an increasing risk of transmission to humans.
Statewide in Illinois, there've been five human cases so far this summer.
