Eastern Equine Encephalitis (EEE) Virus & West Nile Virus (WNV) Confirmed in 2020 Mosquito Samples & Human Cases in Massachusetts

Posted on: August 26, 2020 - 2:00pm

The Massachusetts Department of Public Health (MDPH) announced one human case of WNV infection, diagnosed in a resident of Middlesex County, and three human cases of EEE infection, diagnosed in residents of Hampden and Plymouth Counties, to date in 2020. Additionally, EEE and WNV have been detected in mosquito samples recently collected in multiple counties in Massachusetts.  None of these mosquitoes were collected in Harvard. According to MDPH’s arborvirus risk map (https://www.mass.gov/info-details/massachusetts-arbovirus-update#eee-and-wnv-risk-level-by-city/town-) Harvard is low risk at this time.  This could change throughout the summer and fall, so check this website frequently.

EEE and WNV are rare but serious illnesses spread by the bite of an infected mosquito.  By taking a few, common-sense precautions, people can help to protect themselves and their loved ones: 

  • Use EPA-approved insect repellents any time you are outdoors
  • Wear long-sleeved clothing
  • Schedule outdoor activities to avoid the hours from dusk to dawn during peak mosquito season
  • Repair damaged window and door screens
  • Remove standing water from the areas around your home
