MCHENRY COUNTY, Ill. (CBS) — Illinois has reported its first human case of West Nile Virus this year – and it’s in McHenry County.

The state’s first case of West Nile this year was in Fox River Grove: a woman in her 50s.

“She was not hospitalized, thankfully. She had a very mild case and she has since recovered.”

Debra Quackenbush is spokeswoman for the McHenry County Department of Health.

This first human case in Illinois comes almost a month later than the first case in the state last year, which was reported on July 24: a Cook County case.

Illinois Department of Public Health Spokeswoman Melaney Arnold.

“Urban areas typically tend to see West Nile Virus activity a little bit earlier than is reported in more rural areas.”

She says West Nile mosquitoes are often found around storm sewers, which are mostly in cities and towns.
