No human or animal cases of WNV or Eastern Equine Encephalitis (EEE) have been detected so far this year.
There is no elevated risk level or risk-level change associated with this finding.
“The first WNV positive mosquito sample is often identified in Massachusetts sometime during the last week of June or the first week in July,” said DPH State Epidemiologist Dr. Catherine Brown.
“Risk for human infection generally builds through the season with peak risk occurring in August.” ■
