HARTFORD, CONN (July 31, 2018) –  Yesterday, state officials notified the City of Hartford that mosquitoes trapped on July 24th, 2018 at Keney Park tested positive for West Nile virus (WNV).  There have been no reported cases of anyone with WNV in Hartford, and the Centers for Disease Control and Prevention (CDC) says it is rare for someone who is in infected to develop a serious illness.  Mosquitoes with WNV have been found in more than a dozen Connecticut municipalities this year.  Please see Frequently Asked Questions about WNV from the state here.

“Even though we see the West Nile virus in some form every year in Connecticut, I hope residents will take basic steps to prevent mosquito bites and report any potential West Nile virus infections to a health care professional,” said Mayor Luke Bronin.  “I want to thank the State Department of Energy and Environmental Protection for their work to detect West Nile virus in Hartford.”

The positive mosquitoes are Culex Pipiens, a predominantly bird-feeding species that has been identified with WNV in previous years.  According to the CDC, symptoms of severe illness include high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness and paralysis.

The City of Hartford Department of Health and Human Services recommends the following steps to avoid WNV or other mosquito-borne illnesses:

Preventing mosquito bites:

  • 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, or when mosquitoes are most active. Clothing should be light colored and made of tightly woven materials that keep mosquitoes away from the skin.
  • Use mosquito netting when sleeping in an unscreened structure and to protect small babies when outdoors.
  • Use mosquito repellent, according to directions, when it is necessary to be outdoors.

Preventing mosquitoes at home:

  • Dispose of water-holding containers such as ceramic pots, used tires, and tire swings.
  • Drill holes in the bottom of containers such as those used for recycling.
  • Clean clogged roof gutters.
  • Turn over objects that may trap water when not in use such as wading pools and wheelbarrows.
  • Change water in bird baths on a weekly basis.
  • Use landscaping techniques to eliminate areas where water can collect on your property.
