A fourth resident of DuPage County has died from West Nile Virus, the county health department confirmed.
The death brings DuPage's human West Nile cases to 28, according to the Illinois Department of Public Health, and 138 cases in the state. Details about the fatal case weren't released.
Kane County was the only other area to report a death from the virus this year. A 64-year-old Elgin man, the first person to contract the virus in county, died last month.
The virus also is to blame for the death of Lombard's long-time village president, 76-year-old Bill Mueller, who also had been battling cancer.
The health department recommends using bug spray to keep mosquitoes away, wearing long sleeves and pants after sunset, and generally staying indoors at dawn and dusk.
Most people who get bit by an infected mosquito won't get sick, according to the CDC. Only about one in five will show symptoms, and people most at risk are those with other health issues, such as cancer or diabetes.
