The Adams County Health Department (ACHD) is reporting the first mosquitoes to test positive for West Nile virus in Adams County for 2019. ACHD staff collected mosquitoes testing positive on September 18, 2019 in Quincy.

“The weather is still warm and favorable for West Nile virus activity,” said ACHD Environmental Health Supervisor Tony Dede. “Although we see West Nile virus in Illinois every year, it’s still important to take precautions to protect yourself by wearing insect repellent and getting rid of standing water around your home.”

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 sick horses and humans with West Nile virus-like symptoms. People who observe a sick or dying crow, blue jay, robin or other perching bird should contact the local health department, which will determine if the bird will be picked up for testing.

West Nile virus is transmitted through the bite of a mosquito that 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 50 and individuals with weakened immune systems are at higher risk for severe illness from West Nile virus.

Precautions 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 birdbaths, 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 dead birds to your local health department to help monitor for West Nile virus.
