ILLINOIS (AP) The Illinois Department of Public Health has confirmed the first human case of West Nile virus reported in Illinois for 2017. A Will County resident in his 60s became ill at the end of June. Will County is located in northeastern Illinois. Missouri has already found mosquitoes that tested positive for the virus this year.
The first human case of West Nile virus last year was reported early in the year, on June 6, 2016. Last year, 61 counties in Illinois reported a West Nile virus positive mosquito batch, bird and/or human case. For the 2016 season, Illinois reported 155 human cases, including six deaths.
While Illinois is also monitoring for Zika virus, which is primarily transmitted through the bite of a mosquito, the main type of mosquito that carries Zika virus, Aedes aegypti, is different and is very rarely found in Illinois.
Last month, mosquitoes in St. Louis County tested positive for the West Nile Virus.
