Eastern Equine Encephalitis (EEE) Update

September 30, 2019 6:30 PM 

Today, Quinnipiack Valley Health District (QVHD) received a report that the Bethany trapping station had a Cs. melanura mosquito pool collected on September 23, 2019 test positive for eastern equine encephalitis virus (EEEV). According to the CDC, “Cs. melanura is not considered to be an important vector of EEEV to humans because it feeds almost exclusively on birds.” 

QVHD advises residents of the QVHD to protect themselves and their children by taking personal protective measures to prevent mosquito bites and minimizing outdoor activity from dusk to dawn, when mosquitoes are most active. The Health District will continue to monitor mosquito activity and update messages until the first hard frost. 

QVHD recommends the following precautionary measures:

  • The suspension of school and town sponsored activities from dusk to dawn, when mosquitos are most active.
  • If outdoor activity is unavoidable, especially around dawn or dusk, be sure to use insect repellent and cover bare skin.
  • Use insect repellent, according to label instructions, when it is necessary to be outdoors.
  • Be sure door and window screens are tight-fitting and in good repair.
  • Wear shoes, socks, long pants, and a long-sleeved shirt when outdoors for long periods of time. Clothing should be light-colored and made of tightly woven materials that keep mosquitoes away from the skin.
  • Eliminate mosquito breeding sites by emptying standing water from buckets, barrels and other containers.
  • Consider mosquito-netting for carriages, strollers and tents.

 The Department of Public Health (DPH) continues to advise against unnecessary trips into mosquito breeding grounds such as marshes as the mosquitoes that transmit EEE virus are associated with freshwater swamps. Overnight camping or other substantial outdoor exposure in freshwater swamps in Connecticut should be avoided.
