Boulder Mosquito Pool Tests Positive for West Nile Virus

Wednesday, June 18, 2014

Boulder County, Colo. - Boulder County Public Health has confirmed that mosquitoes in a mosquito pool in Boulder have tested positive for West Nile virus (WNV). The positive pool came from traps located at Christensen Park near Kings Ridge Boulevard and Tom Watson Park on 63rd Street. Positive mosquito pools have been confirmed in four other Colorado counties this year: Delta (1), Weld (2), Mesa (1), and Adams (1).

“Unfortunately, wet weather followed by high temperatures creates an ideal environment for mosquitos to breed,” said Lane Drager, Boulder County Public Health Consumer Protection program coordinator. “Now is the time to take steps to protect ourselves and our families from West Nile virus.”

WNV is transmitted to humans from the bite of an infected mosquito. While most infections are mild, the more serious infections can cause encephalitis (inflammation of the brain) and/or meningitis (inflammation of the brain's lining), loss of vision, paralysis, coma, tremors, convulsions, and death.

Symptoms of WNV include fever, extreme fatigue, headache, body aches, and occasionally can also include skin rashes and swollen lymph nodes. Generally, symptoms appear 3 to 14 days after being bitten by an infected mosquito. Anyone who experiences these symptoms should consult their health care providers.

Boulder County Public Health officials urge residents to take necessary precautions to protect themselves. Keep safe this summer, and remember the 4Ds:

  1. Use DEET-enhanced insect repellent or alternative.
  2. DRESS in long sleeves and pants.
  3. Avoid the outdoors from DUSK until DAWN.
  4. DRAIN standing water outside your home.

Generally, the mosquito season extends from late April until mid-October, with the end usually signaled by the first freeze in the fall.

As of June 17, there have been no human cases of WNV reported in Colorado. Nationally, two cases have been reported in Mississippi so far this season.

In 2013, there were 51 cases of the disease in Boulder County, 320 cases in Colorado, and 2,469 nationally.
