[ARCHIVED] Mosquitoes in St. Charles County Test Positive for West Nile Virus

July 25, 2018

St. Charles County, Missouri – Mosquitoes collected yesterday in traps set by the St. Charles County Division of Environmental Health and Protection have tested positive for the West Nile virus. This is the first positive test for the county this year. Residents should not be alarmed or panicked by this finding, but aware and vigilant in their personal efforts to discourage mosquito bites.

“County staff has been aware that West Nile virus is present in the metropolitan area this season. Now that the virus has appeared in St. Charles County, we are increasing treatment protocols for the surrounding areas,” explains Ryan Tilley, Director of the Division of Environmental Health and Protection. “St. Charles County Mosquito Control Program staff are targeting known habitat areas to minimize the development of adult mosquitoes. This will assist us in controlling the spread of the virus.”

Tilley says a team effort between residents and the St. Charles County Mosquito Control program helps to “Block the Bite” and reduce exposure to mosquito bites and related illnesses. Residents can reduce the risk of contracting West Nile by using repellent containing DEET, picaridin, IR 3535, or oil of lemon eucalyptus when outdoors the rest of the summer and into fall. Additionally, they should remove or treat areas where water settles for several days, and keep gutters and yards free of debris where mosquitoes may collect.

This is the second year the County has used collection sites to analyze distribution and types of mosquitoes. The traps were set up in various sites throughout the county in June, and will remain in place through September. The traps are checked and collections analyzed weekly.

“By using information from these collection sites,” Tilley says, “our staff can target specific areas where we need to decrease the overall mosquito population in the county.”

According to the Centers for Disease Control and Prevention (CDC), 33 states, including Missouri and Illinois, have reported West Nile virus activity this year. Approximately 80 percent of those who become infected with the virus do not experience any discomfort. Those who do can show symptoms such as fever, headache, body ache, fatigue, nausea or rash. In extreme cases, especially involving those 60 or older or who have previous medical conditions, the disease can cause brain inflammation, neck stiffness, seizures, coma and death.

The purpose of the St. Charles County Mosquito Control program is to inspect problem areas and apply effective treatments to reduce the mosquito population; target habitat areas to control larvae; and spray to treat adult mosquitoes. In addition to efforts throughout unincorporated St. Charles County, the division contracts with several municipalities, including Augusta, Cottleville, Dardenne Prairie, Flint Hill, Lake Saint Louis, Portage des Sioux, St. Paul, Weldon Spring, Weldon Spring Heights and Wentzville. Residents who are concerned about nuisance mosquitoes should visit sccmo.org/mosquito or call 636-949-1800 to request assistance. Those living within the city limits of O’Fallon, St. Charles and St. Peters should contact their respective city halls for information.
