First Case Of West Nile Virus In Illinois

Updated:

The Illinois Department of Public Health has confirmed the first human case of West Nile virus this year. The Cook County Health Department reported a man in his 80s became ill earlier this month and the Franklin-Williamson Bi-County Health Department confirms a man in his 30s became ill in July. There is no information on their condition.

Health officials say they are also seeing an increase in infections in birds and mosquitoes. Mosquitoes carry the infection, so be sure to take precautions like using bug repellant and avoid being out at dawn or dusk when the mosquitoes are active. 

Most people with the virus have no clinical symptoms of illness, but some may become ill three to 15 days after being bitten by an infected mosquito.
