West Nile Virus Found in Jefferson County Mosquitoes | St. Louis News

West Nile virus has been detected in mosquitoes in Arnold and De Soto, Jefferson County — a serious but not yet alarming development. While officials have deployed control measures in De Soto, Arnold remains outside their jurisdiction. No human cases have been reported yet, but experts warn the virus is active during warmer months. Most infected people show no symptoms, but about 1 in 5 may experience fever, headaches, or vomiting — and in rare cases, severe neurological issues. Stay safe by avoiding outdoor activity during peak mosquito hours, eliminating standing water around your home, and keeping windows and doors closed.
