EASTON, Mass. (WHDH) -- State officials began another round of spraying to reduce the risk of the EEE virus in towns in Southeastern Massachusetts.

Officials urge residents to be vigilant and to use precaution when going outside.

Multiple mosquito samples tested positive for EEE in Easton and surrounding communities in recent days. Residents said they’d rather be safe and maybe have to cancel some outdoor plans than be sorry.

So far this year, Massachusetts has seen one human case of EEE.

The state raised the level in Bridgewater, Easton, Raynham and Taunton to critical, while West Bridgewater and Norton have increased from moderate to high.
