KAYSVILLE – Residents of Davis County may wish to dig up the mosquito repellent from the back of the bathroom cabinet if they have not already done so.
In the last three weeks, "hot spots" of mosquitoes that have proven to be positive for West Nile viruses have occurred throughout the county – both in rural and urban areas.
Government officials found over 65 groups of mosquitoes tested positive for the disease in about 50 different locations On Wednesday, Gary Hatch, Davis district head of mosquito control, told KSL.com. Clearview's Bayview Duck Club tested most of the mosquito groups on West Nile, and the district found other critical spots near the boundary between West Layton and Syracuse, West Kaysville, the Oakridge Country Club border at Farmington, the South Davis Sewer District at West Bountiful and the New State Duck Club at Woods Cross after Hatch 59002] Also in Weber County, Sevier County and Moab mosquitoes have been reported to have proven to be West Nile positive.
Using a calculation called "minimal infection rate," the district can often determine whether mosquitoes with viruses are affecting the population in the area. "The higher the rate, the more likely it is that the West Nile Virus infects the human population, "said Hatch. "The minimum infection rate (in Davis County) is definitely quite high," he said. "We had hoped it would have calmed down somewhat this week, but right now we find that groups test positive." … This warm weather does not help. "
In an attempt to fight the mosquitoes, the district sends crews at night to spray insects nearby, as well as crews who go out during the day to find mosquitoes and kill larvae in wetlands.
"(mosquitoes) play a very minor role in the ecosystem. There is not really one thing that mainly feeds on mosquitoes, especially here in Utah. They pollinate some flowers, but unfortunately, here in Utah, many of the flowers they pollinate are harmful weeds. The mosquitoes that transmit the West Nile virus are out from dusk to dawn. Residents venturing out in the dark should wear long sleeves, long trousers and closed shoes. Mosquitoes, however, can sting through lightweight T-shirts that fit snugly against the skin. That's why Hatch recommends thicker, more baggy clothing. Mosquitoes are attracted to the carbon dioxide that exhales people and can feel it up to 1
He also urged residents to remove stagnant water around the house.
While most cases of West Nile virus are mild and there is no known vaccine or cure for the virus in humans. Disease symptoms include high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness, and paralysis.
Recovery from the symptoms may take several weeks or months; and in some cases, the central nervous system may be permanently affected. About one in ten people who develop a strain of West Nile virus that affects their nervous system will die, according to the CDC.
While the virus can infect anyone at any age, people over 60 and people with certain conditions such as cancer or diabetes are at higher risk.
