A woman in her 50s from Fox River Grove was not hospitalized and has since recovered, according to a department news release.
Last year, McHenry County reported six human cases of West Nile virus. One human case was reported in the county in both 2011 and 2010.
This year, nine mosquito batches and six birds have tested positive for the virus in McHenry County. The Illinois Department of Health recorded 290 human cases in 20 counties in 2012, including 12 deaths, as compared with 34 human cases and three deaths in 2011.
