Chicago, IL-(Effingham Radio)- The Illinois Department of Public Health (IDPH) is reporting the first bird to test positive for West Nile virus in Illinois for 2024 in Douglas County. The specimen was collected by Douglas County Health Department staff on April 2 in Villa Grove. The early report of the first bird comes following a mild winter and spring.
“The news of the first bird with West Nile virus so early in the season is a signal for Illinois residents to begin protecting themselves – and their horses – from vector-borne diseases,” said IDPH Director Dr. Sameer Vohra. “We urge everyone — and especially older people and those with weakened immune systems — to take precautions to protect themselves and their families from mosquitoes and the viruses they carry by wearing insect repellent and eliminating standing water around their home where mosquitoes breed. Please ‘Fight the Bite’ by practicing the three R’s – reduce, repel, and report.”
Director Vohra added that horses can be protected from West Nile virus by vaccination.
Monitoring for West Nile virus in Illinois includes laboratory tests for mosquito batches, dead birds, as well as testing sick horses and humans with West Nile virus-like symptoms. People who see a sick or dead crow, blue jay, robin or other perching bird should contact their local county or city health department, which will determine if the bird will be picked up for testing.
West Nile virus is transmitted through the bite of a Culex mosquito, commonly called a house 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. Most people infected with West Nile virus will not show any symptoms; however, in rare cases, severe illness including meningitis, 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.
Last year, 67 Illinois counties reported a West Nile virus positive mosquito batch, bird, horse, and/or human case, up from 44 counties in 2022. Last year, there were 119 human cases of West
Nile virus and six deaths reported in Illinois, according to provisional data, compared to 33 human cases and seven deaths in 2022. IDPH notes human cases are underreported and do not reflect the actual number of cases.
IDPH encourages the public to Fight the Bite by 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 light-colored, long-sleeved shirt, and apply an EPA-registered insect repellent that contains DEET, picaridin, oil of lemon eucalyptus, IR 3535, para-menthane-diol (PMD), or 2-undecanone according to label instructions. Consult a physician before using repellents on infants.
- REPORT – report locations to your local health department where you see water sitting stagnant for more than a week such as roadside ditches, flooded yards, and similar locations that may produce mosquitoes. The local health department or city government may be able to add larvicide to the water, which will kill any mosquito larvae.
