Mosquitoes in Groton. Ledyard, North Stonington and Stonington Test Positive for Eastern Equine Encephalitis (EEE)

Ledge Light Health District announced today that mosquitoes trapped in Groton and Ledyard have tested
positive for Eastern Equine Encephalitis. This is in addition to the previously announced positive
mosquitoes in North Stonington and Stonington. Some of the mosquito traps contained mosquito species that
are known to bite humans.

EEE is a rare but serious disease caused by a virus that is transmitted by mosquitoes. Historically, the
virus has been found in trapped mosquitoes in Connecticut, but only one person has died from EEE.

All residents of Groton, Ledyard, North Stonington and Stonington are advised
to avoid outdoor activities from one hour before to one hour after dawn and dusk.

Additional precautions to avoid mosquito bites include:
• Be sure door and window screens are tight fitting and in good repair.
• While outdoors, wear shoes, socks, long pants, and long-sleeved shirts. Clothing material should
be tightly woven.
• Use mosquito netting if sleeping outdoors.
• Consider using mosquito repellent when it is necessary to be outdoors and
always use them according to label instructions. The most effective repellents
contain DEET or Picaridin. Oil of lemon eucalyptus is also effective for brief
periods of exposure.
• When using DEET, use the lowest concentration effective for the time spent
outdoors (for example, 6% lasts approximately 2 hours and 20% for 4 hours)
and wash treated skin when returning indoors. Do not apply under clothing, to
wounds or irritated skin, the hands of children, or to infants less than 2 months.
Measures to reduce mosquitoes around the home include:
• Dispose of water-holding containers, such as ceramic pots, used tires, and tire
Swings, clogged gutters.
• Drill holes in the bottom of containers such as those used for recycling.
• Change water in bird baths on a weekly basis.
• Clean and chlorinate swimming pools, and cover pools when not in use.
• Use landscaping to eliminate areas where water can collect on your property.
