The weather may be cooling off but state public health officials are warning that mosquito-borne illnesses remain a threat, after two more Massachusetts residents were diagnosed with West Nile virus. Six people in the state have been diagnosed with the illness so far this year.
The state Department of Public Health said Friday that a Middlesex County woman in her 50s and an Essex County woman in her 70s were both recently infected. They said the older woman was hospitalized but has since shown significant improvement. The agency said the younger woman didn’t need to be hospitalized.
