KAYSVILLE – Davis County residents may want to dig the mosquito repellent on the back of the bathroom cabinet if they haven't already.
Over the last three weeks, mosquito hot spots that tested positive for West Nile virus have been appearing throughout the county – both in rural and urban areas.
County officials found more than 65 groups of mosquitoes that tested positive for the disease in about 50 different places, and they can find more as the day comes to a close, Davis Garry's mosquito control district Hatch said in front of KSL.com on Wednesday.
The Bayview Club in Clarefield had the most positive tests for mosquito groups for the West Nile, and the area found other hot spots near the boundary of West Leighton and Syracuse, west Caysville, the boundary of the Ourige Country Club in Farmington, Farmington. South Davis at West Bounty and the New York Pathetic Club at Woods Cross, according to Hatch. [1
The area can often tell whether mosquito-borne viruses will affect people in the area by calculating a "minimum infection rate" The higher the percentage, the more likely the West Nile virus will affect the human population,
"The minimum infection rate (in Davis County) is definitely quite high," he said. "We were hoping it would calm down a little this week, but we're finding (the groups are testing positive).… It's warm time does not help. ”
In an effort to fight mosquitoes, the area sends a team of grazing at night to spray insects in nearby neighborhoods, as well as crews going out during the day to find and kill mosquitoes. Larvae in wetlands.
"(Mosquitoes) play a very small role in the ecosystem. which mainly feeds on mosquitoes, especially here in Utah. They pollinate some flowers, but unfortunately here in Utah, many of the pollinated flowers are harmful weeds. So they are kind of a double hit, "Hatch said .
The mosquitoes that carry the West Nile virus are outside from dusk until dawn, so residents who go outside while it is dark should wear long sleeves, long pants and closed shoes. Mosquitoes can bite through lightweight t-shirts that are snug on the skin, so Hatch recommends denser, dirtier clothing.
It's also mandatory to carry mosquito repellent with DEET, an oily liquid often used in insect repellents, Hatch said. Mosquitoes are attracted by carbon dioxide, which is exhaled by humans and can be felt up to 100 meters away. The repellent confuses their senses, though even small patches of bare skin are vulnerable to insects, Hach explained.
He also urged residents to remove any standing water around the home.
While most cases of West Nile virus are mild and not reported, there is no known vaccine or cure for the virus in humans. Symptoms of the disease include fever, headache, neck stiffness, stupor, disorientation, coma, tremor, seizures, muscle weakness, loss of vision, numbness and paralysis, according to the Centers for Disease Control and Prevention.
Recovery from symptoms may take several weeks or months; and in some cases the central nervous system may be affected permanently. About one in every 10 people who develop a strain of West Nile virus that affects their nervous system will die, CDC claims.
While the virus can affect anyone at any age, people over 60 and those with certain medical conditions, such as cancer or diabetes, are at greater risk.
