The Illinois Department of Public Health reported there to be a total of 60 cases of West Nile so far this year -- not including the latest numbers from DuPage. Cook County had the most: 44.
Health officials say the virus is transmitted to people by infected mosquitoes, but it can be prevented by using insect repellents when outdoors, wearing long sleeves and pants from dusk to dawn, installing or repairing screens on windows and doors, and emptying standing water from items outside the home.
The DuPage Health Department reports that the risk of West Nile is elevated and it may remain so until cooler temperatures arrive. Officials said they're urging residents to be cautious, but not to curtail outdoor activities.
