Despite cooler weather over the past several days, it's still mosquito season, and that means there's the potential for West Nile Virus cases.
The St. Louis County Department of Health has reported its first suspected human case. A 12-year-old boy from Wellston was briefly hospitalized with West Nile symptoms, though the department says he has returned to normal activities.
The county says there was one human case last year.
The Illinois Department of Public Health says a Cook County man in his 80s got sick earlier this month. A 30-year-old from south-central Illinois became ill in July. In 2010, the first human case was reported on Aug. 31 - 61 people eventually tested positive.
