Public health officials in Massachusetts warned residents to take extra precautions due to a heightened risk of Eastern Equine Encephalitis virus, or EEE virus, a rare mosquito-borne infection that can cause severe neurological problems.

The Massachusetts Department of Public Health said in a press release on Saturday that 10 communities have been raised to high or critical risk for the EEE virus, prompting aerial spraying for mosquitos in Plymouth County. Authorities will also use trucks to spray for insects in parts of Worcester County.
