Frisco confirms first human case of West Nile virus this year


Health Department Senior Sanitarian Angie Crawford says a mosquito pool east of Bloomington collected August first from the 61705 area code has tested positive for the virus.

An infected crow was discovered Thursday in Santa Clara, the county's first sign of the virus of the year. "The West Nile virus seems to be here to stay, so the best way to avoid the disease is to reduce exposure to and eliminate breeding grounds for mosquitoes". About 80-100 cases are reported nationwide each year.

But La Crosse virus is "kind of a different animal" that the health department sees "on occasion", according to Stanley Mills, director of environmental services. "Coma and paralysis occur in some cases". "We have the staff capability to do it". For instance, in our area, Asian Tiger mosquitoes which are carriers for Zika virus primarily bite very aggressively during the day.

La Crosse was only found in Kanawha County. Those who do become ill usually experience mild symptoms such as fever, headache, muscle ache, rash, and fatigue. While most people who are infected develop no symptoms, less than 1 percent of people may develop a serious neurological illness. The virus' symptoms can appear 13 to 14 days after an infection.

The Wisconsin Division of Public Health will continue surveillance for West Nile virus until the end of the mosquito season.

The health department urges people who are outdoors from dawn till dusk to reduce exposure by wearing long trousers, long-sleeve shirts, shoes, and socks.

West Nile virus is most commonly transmitted by mosquitoes, according to the CDC.

Use a mosquito repellent with an EPA-registered ingredient such as DEET while you are outdoors.
