Davis County mosquitoes test positive for West Nile virus



KAYSVILLE – Davis County residents may want to dig out the mosquito repellent on the back of the bathroom cabinet if they haven't already.

Over the past three weeks, "hot spots" of mosquitoes that tested positive for West Nile virus have emerged throughout the county – both in the countryside and in the cities.

County officials found over 65 groups of mosquitoes that tested positive for the disease in about 50 different locations, and they can find more when today's test comes to an end, Davis & # 39; Mosquito Control District Manager Gary Hatch told KSL.com Wednesday.

The Bayview Duck Club in Clearfield had the largest number of mosquito groups that were positive to West Nile, and the district found other hotspots near the West Layton and Syracuse, West Kaysville borders, the Oakridge Country Club in Farmington, the South Davis Sewer District in the West Bountiful and New State Duck Club in Woods Cross, according to Hatch.

9659002] Mosquitoes that tested positive for West Nile have also been reported in Weber County, Sevier County and Moab.

The district can often say whether virus-carrying mosquitoes will affect people in the area through a calculation called "minimal infection rate." The higher the rate, the more likely the West Nile virus will affect the human population, Hatch explained.

"The minimum infection rate (in Davis County) is definitely pretty high," he said. "We were hoping it would have calmed down a bit this week, but right now we find (groups are testing positive). … This warm weather helps not. "

In an effort to fight the mosquitoes, the district dispatches herds at night to spray the insects in nearby neighborhoods, as well as herds that go out during the day to find and kill mosquito larvae in wet areas.

" ( Mosquitoes) have a very small role in the ecosystem. There is not really one thing that mainly feeds on only mosquitoes, especially here in Utah. They pollinate some flowers, but unfortunately Here in Utah, a lot of flowers are pollinating harmful weeds. So they give you a double hit, "Hatch said.

The mosquitoes carrying the West Nile virus are outside from dusk to dawn, so residents who venture outside while it's dark should wear long sleeves, long pants and closed shoes. Mosquitoes can bite through light T-shirts that are hard on the skin, so Hatch recommends thicker, lighter clothes.

It is also necessary to carry mosquito repellent with DEET, an oily liquid that is often used in insecticides, Hatch says. carbon dioxide that humans exhale and can feel it up to 100 meters away, dismissively confusing their senses, although a small patch of detected skin is vulnerable to the insects, Hatch explained.

He also urged residents to remove all standing water around at home.

While most cases of the West Nile virus are mild and go unreported, there is no known vaccine or cure for the virus in humans. high fever, headache, neck stiffness, anesthesia, disorientation, coma, shaking, cramps, muscle weakness, vision loss, numbness and paralysis, according to the Centers for Disease Control and Prevention.

Recovering from symptoms can take several weeks or months; and in some cases, the central nervous system can be permanently affected. About one in ten people who develop a strain of the West Nile virus that affects their nervous system will die, the CDC claims.

While the virus can affect anyone of any age, people over 60 and people with certain medical conditions, such as cancer or diabetes, are at greater risk.
