"Although we’re getting into fall and cooler temperatures, we’re
not out of the woods regarding the risk of West Nile virus," said
Dr. Damon T. Arnold, state public health director. "Mosquitoes are
still present until freezing temperatures are consistent, so we must
be cautious and protect ourselves from mosquito bites."
At this time last year the Illinois Department of Public Health
had received reports of 215 human cases of West Nile virus, compared
with 81 human cases so far this year. There have also been four
deaths from human cases in Illinois this year.
So far this year a total of 43 Illinois counties have reported
mosquito samples, birds, horses or humans positive for West Nile
virus.
The following county health departments are reporting their first
West Nile-positive samples for 2007:
In 2006, the first West Nile-positive mosquito sample was
reported May 24 in DuPage County, and the first human case was
reported Aug. 1 in St. Clair County. Last year, 77 of the state’s
102 counties were found to have a West Nile-positive bird, mosquito,
horse or human case. A total of 215 human cases of West Nile
disease, including 10 deaths, were reported last year in Illinois.
Surveillance for West Nile virus in Illinois began May 1 and
includes laboratory tests on mosquitoes, dead crows, blue jays,
robins and other perching birds, as well as the testing of sick
horses and humans with West Nile-like disease symptoms. Citizens who
observe a sick or dying crow, blue jay, robin or other perching bird
should contact their local health department, which will determine
if the bird is to 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. Most
people with the virus have no clinical symptoms of illness, but some
may become ill three to 14 days after the bite of an infected
mosquito.
Only about two out of 10 people who are bitten by an infected
mosquito will experience any illness. Illness from West Nile is
usually mild and includes fever, headache and body aches, but
serious illness, such as encephalitis and meningitis, and death are
possible. People older than 50 years of age have the highest risk of
severe disease.
The best way to prevent West Nile disease or any other
mosquito-borne illness is to reduce the number of mosquitoes around
your home and take personal precautions to avoid mosquito bites.
Precautions include:
-
Avoid being
outdoors when mosquitoes are most active, especially between
dusk and dawn. Use prevention methods whenever mosquitoes are
present.
-
When outdoors,
wear shoes and socks, long pants and a long-sleeved shirt, and
apply insect repellent that includes DEET, picaridin or oil of
lemon eucalyptus 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 flowerpots, clogged roof gutters, old tires and any
other receptacles. Change water in birdbaths weekly. Properly
maintain wading pools, and stock ornamental ponds with fish.
Cover rain barrels with 16-mesh wire screen.
-
In communities where there are
organized mosquito control programs, contact your municipal
government to report areas of stagnant water in roadside
ditches, flooded yards and similar locations that may produce
mosquitoes.
