(AP) Experts say what has so far been a cool, wet summer is probably limiting West Nile virus in Illinois.
Melaney Arnold, spokeswoman for the Illinois Department of Public Health, says that a year ago 4 percent of the mosquitoes trapped in counties around the state carried West Nile. At this point in 2012 that figure was 14 percent. But this year it's just 1 percent.
University of Illinois Extension Entomologist Phil Nixon says there are plenty of mosquitoes around. But most aren't the Culex mosquitoes that transmit the virus.
But a run of hot, dry weather that favors Culex could increase their numbers.
A bird in Peoria County, and one in Woodford County recently tested positive for West Nile.
