2 more human West Nile cases confirmed

State public health officials say two more human cases of mosquito-borne West Nile virus have been confirmed in Massachusetts.

They are the second and third confirmed human cases in the state this year.

The Department of Public Health announced Thursday that an elderly woman from Worcester County was hospitalized on Aug. 19 after developing symptoms. She has since been discharged.

A Middlesex County woman between the ages of 45 and 64 remains hospitalized, but is improving.

Officials say contracting West Nile virus or Eastern equine encephalitis from infected mosquitoes is possible until the first hard frost of the fall.
