The Illinois Department of Public Health is reporting the first confirmed human case of West Nile virus in 2018.
A Chicago resident in her 60’s became ill in mid-May.
“Because the case occurred earlier in the season than we typically see human cases of West Nile virus in Illinois, IDPH requested additional testing by the Centers for Disease Control and Prevention and we received confirmation on June 19,” said IDPH Director Nirav D. Shah, M.D., J.D. “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.”
The first human case of West Nile virus in 2017 was reported on July 20, 2017. 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.
The IDPH recommends residents protect themselves 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 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. The local health department or city government may be able to add larvicide to the water, which will kill any mosquito eggs.
