West Nile Virus-Infected Mosquitos Found Near O'Hare, Beverly

CHICAGO — The Chicago Department of Public Health has confirmed the first mosquito batches that have tested positive for West Nile Virus this year.

Positive batches were discovered in the O’Hare International Airport area and the Beverly neighborhood on Chicago’s South Side, Ald. Matt O’Shea (19th) said in an email blast to constituents. The positive batch was found near 95th Street and Ashland Avenue. The public health department will continue monitoring the areas where mosquitos have tested positive and take appropriate precautions following further testing.

CDPH places Gravid traps throughout the city, which are monitored twice a week during mosquito-breeding season. According to city’s West Nile Surveillance Report from July 12, out of 108 pools tested, four tested positive, affecting two community areas.

In addition to trapping, the city treats catch basins with larvicide, which kills immature mosquitos. No human cases have been reported, and no dead birds have been found.

The best way to prevent infection from West Nile Virus and other mosquito-borne diseases it to reduce the number of mosquitos around your home. Residents are encouraged to:

• Use insect repellant that contains DEET, Picaridin, IR3535 or Oil of Lemon Eucalyptus.

• Eliminate standing water.

• Keep grass and weeds short.

• When outside between dusk and dawn, wear loose-fitting, light colored clothing, long pants, long-sleeved shirts, socks and shoes.

• Make sure all screens, windows and doors are tight fitting and free of holes.

• Check on neighbors regularly, especially those who are older or need additional assistance.
