West Nile virus has been confirmed in mosquitoes collected from Arlington, the town’s Health Department said Thursday. Christine Bongiorno, Arlington director of health and human services, reminded residents to protect themselves by avoiding the insect when possible and removing any standing water, which is a breeding ground for mosquitoes. West Nile has been identified in mosquitoes in 14 other Massachusetts cities and towns this year, including locations in Bristol, Essex, Middlesex, Norfolk, Suffolk, and Worcester counties, according to data from the state Department of Public Health.
