Egyptian Health Department (EHD) is reporting the first positive mosquito batches for West Nile virus in White County for 2018. Two separate batches of mosquitoes collected in Carmi tested positive for West Nile Virus on Friday, August 3. Illinois Department of Public Health Director, Dr. Nirav D. Shah, says “West Nile virus can cause serious illness in some people so it’s important that you take precautions like wearing insect repellent and getting rid of stagnant water around your home.”
Last year, 63 counties in Illinois reported a West Nile virus positive mosquito batch, bird and/or human case. For the 2017 season, IDPH reported 90 human cases (although human cases are underreported), including eight deaths.
West Nile virus is transmitted through the bite of a Culex pipiens mosquito, commonly called a house mosquito, which has picked up the virus by feeding on an infected bird. Common symptoms include fever, nausea, headache and muscle aches. Symptoms may last from a few days to a few weeks. However, four out of five people infected with West Nile virus will not show any symptoms. In rare cases, severe illness including meningitis or encephalitis, or even death, can occur. People older than 60 and individuals with weakened immune systems are at higher risk for severe illness from West Nile virus.
Precautions to Fight the Bite include practicing the three “R’s” – reduce, repel, and report.
REDUCE – make sure doors and windows have tight-fitting screens. Repair or replace screens that have tears or other openings. Try to keep doors and windows shut. Eliminate, or refresh each week, all sources of standing water where mosquitoes can breed, including water in bird baths, ponds, flowerpots, wading pools, old tires, and any other containers.
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 repellents on infants.
REPORT – report locations where you see water sitting stagnant for more than a week such as roadside ditches, flooded yards, and similar locations that may produce mosquitoes. EHD may be able to add larvicide to the water, which will kill any mosquito eggs. Monitoring for West Nile virus in Illinois includes laboratory tests for mosquito batches, dead crows, blue jays, robins and other perching birds, as well as testing humans with West Nile virus-like symptoms. People who observe a sick or dying crow, blue jay, robin or other perching bird should contact EHD, which will determine if the bird will be picked up for testing.
