Massachusetts Arbovirus Update

Current Eastern Equine Encephalitis (EEE) and West Nile Virus (WNV) risk levels in Massachusetts

Routine mosquito testing ends on October 11, 2019. Risk for EEE and WNV will exist until the first hard frost.

It remains important for people in communities at critical, high and moderate risk for EEE to continue to take personal precautions against mosquito bites. These steps include using EPA-approved bug spray, wearing long sleeves and pants outdoors to reduce exposed skin, and cancelling outdoor activities in the hours from dusk to dawn when mosquitoes are most active.
