Longmont Mosquito Pool Tests Positive for West Nile Virus

Wednesday, June 18, 2014

Boulder County Public Health has confirmed that mosquitoes in a mosquito pool in Longmont have tested positive for West Nile virus (WNV). The positive pool came from traps located at the Boulder County Fairgrounds and St. Vrain Greenway at Emery Street. Positive mosquito pools have been confirmed in four other Colorado counties this year: Delta (1), Weld (2), Mesa (1), and Adams (1).

“This is the second positive pool in Boulder County in just two days, and in different parts of the county,” said Lane Drager, Boulder County Public Health Consumer Protection program coordinator. “So, no matter where you live, now is the time to be proactive in protecting 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.

There is no treatment, cure, or human vaccination for the virus. Health care providers can only treat the symptoms to help patients feel better and possibly recover more quickly.

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.
