West Nile Virus case confirmed in Evanston

The City of Evanston’s Health Department has received a report of the first human case of West Nile virus in the city this year.

The case was reported in a 60-year-old resident of Evanston. Fifteen other Illinois residents with West Nile virus have been reported this year, while 117 cases were diagnosed in 2013.

West Nile virus is transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected bird. Common West Nile virus symptoms include rash, 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 age 50 are at higher risk for severe illness from West Nile virus.

"Residents need to be cognizant that West Nile virus prevention does not stop with the adult mosquito operations performed by the North Shore Mosquito Abatement District," said Evanston Health Department Director Evonda Thomas-Smith. 

The best way to prevent WNV 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:

  • Avoid being outdoors when mosquitoes are most active, especially between dusk and dawn
  • 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
  • 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, especially at night
  • Eliminate all sources of standing water that can support mosquito breeding, including water in bird baths, ponds, flower pots, wading pools, old tires, and any other receptacles. Email the North Shore Mosquito Abatement District at [email protected] or call 847-446-9434 to report areas of stagnant water in roadside ditches, flooded yards and similar locations that may produce mosquitoes.
