BOSTON (WGGB/WSHM) - The Massachusetts Department of Public Health is reporting the eighth human case of West Nile Virus this year.
Officials said a woman in her thirties was exposed in Middlesex County, in an area where other cases have already been detected this season. 7 of the 8 human cases so far have been linked to parts of Middlesex and Suffolk counties now classified as “high risk” for West Nile.
Most other communities across the state, including here in western Mass., are at moderate risk. Since mid-June, labs have found 327 mosquito samples positive for West Nile Virus in counties from Barnstable to Berkshire, but no animal cases so far.
