Winnebago County - The Winnebago County Health Department announces today that they have one positive mosquito pool with West Nile Virus (WNV) in the 61073 Zip Code. There are no human cases to report.

At this time, WNV is presumed to be present throughout Winnebago County, and appropriate precautions should be taken to protect yourself and family members from being bitten by an infected mosquito, said Winnebago County Health Departments Environmental Health Director, Todd Marshall.

The best way to prevent West Nile virus or any other mosquito-borne illness is to reduce the number of mosquitoes around your home and to take personal precautions to avoid mosquito bites. Precautions include practicing the three R’s reduce, repel and report.

ü  REDUCE exposure - avoid being outdoors when mosquitoes are most active, especially between dusk and dawn. 

  •        Make sure doors and windws have tight-fittinscreens. Repair or replace screens that have tears or other openings. Try to keep doors and windws shut, especially at night.
  •        Eliminate all sources of standing water whermosquitoes can breed, including watein bird baths, ponds, flowepots,wadinpools, old tires and any othereceptacles. Mosquitcan breed in a capful of water.

ü  REPEL - when outdoors, wear shoes and socks, long pants and a long-sleeved shirt, and apply insect repellent that contains DEET, picaridin, oil of lemon eucalyptus or IR 3535, according to label instructions. Consult a physician before using insect repellents on infants.

WNV activity is earlier than in past seasons and is influenced by many environmental factors that impact viral activity including weather, host and vector concentrations, immune status, and others. Since the beginning of the 2017 season in April throughout seven (7) counties in Illinois, there have been 6 human cases of WNV, and 14 positive mosquito pools. Based on nationwide experience over the previous six (6) years of WNV presence in the United States, the peak period for WNV transmission, particularly to humans, has been from the end of August through the middle of September.
