There’s been one human case of West Nile Virus reported in Illinois, the first case for 2020. The Illinois Department of Public health said the case is a DuPage County resident. It's a woman in her 40s who became ill in mid-August. The virus is spread through mosquitoes that feed off infected birds. Human symptoms include fever, nausea, headache and muscle aches and could last a few days or a few weeks. Most infected people show no symptoms.
A batch of mosquitoes collected in Bourbonnais have tested positive for West Nile. That’s according to the Kankakee County Health Department. Illinois officials report 17 Illinois counties have had positive tests.
