EEE Updates and Information

On Tuesday, September 10, 2019, the Massachusetts Department of Public Health (DPH) announced that it will conduct aerial mosquito spraying in Massachusetts communities, including Medfield. DPH has not announced the specific night that Medfield will be sprayed, but has announced that no precautions are necessary for the aerial spraying. Spraying will take place in the evening and overnight, beginning at 7:15 pm. The spraying is weather and equipment dependent.

Additional information about EEE can also be found here.

On Thursday, August 29, 2019, the DPH confirmed a horse case of Eastern Equine Encephalitis (EEE) in the Town of Medfield and raised the Town’s risk level to critical. Town-wide spraying by truck by the Norfolk County Mosquito Control District took place on Friday, August 30 after dusk.

All Town and Medfield Public Schools outdoor activities, including sports practices, will now end at dusk and night games will be rescheduled.  

The Town is following Department of Public Health guidelines and is advising all residents to limit outdoor exposure after sundown. Residents should strongly consider cancelling or rescheduling any planned outdoor activities until further notice.

The Department of Public Health recommends for people in communities at critical risk for EEE to continue to take personal precautions against mosquito bites. Avoid mosquito bites by wearing long sleeves and pants, avoid the hours when mosquitoes are most active (dusk through dawn), wear insect repellent, and mosquito-proof your home by limiting the number of places for mosquitoes to breed by draining or discarding items that hold water.

The Medfield Board of Health has put information mosquitoes and mosquito borne disease on their website here: 

The Board of Health is in constant contact with MDPH and will update this information if and when more information becomes available.  More information on mosquito control for EEE is available on the state website at:
