The announced on Tuesday that there are now 12 human cases of West Nile virus (WNV) in DuPage County.  Those affected by WNV are in their 20s-70s, and are located in Carol Stream, Downers Grove, Elmhurst, Hinsdale, Lisle, Lombard, Naperville, Villa Park and Westmont.  One of those 12 cases resulted in a fatality related to WNV infection.

According to an interactive map of mosquito testing in the area, traps in Wheaton last tested positive for the disease Aug. 10, Aug. 8 and Aug. 1.

The Wheaton trap that tested positive Aug. 10 is located near , just north of the ntersection of Blanchard Street and Naperville Road. The trap that tested positive Aug. 8 is located near Cantigny on Shaffner Road, south of Roosevelt Road. A trap in Warrenville also last tested positive Aug. 10.

 
WNV is transmitted to people by infected mosquitoes, and can be prevented by:

• Using insect repellents when you go outdoors.
• Wearing long sleeves and pants from dusk to dawn.
• Installing or repairing screens on windows and doors.  Using air conditioning, if you have it.
• Emptying standing water from items outside your home such as flowerpots, buckets and kiddie pools.

The Health Department reminds County residents that the presence of WNV is widespread in the DuPage County environment so the risk of WNV is elevated and may remain so until the arrival of cooler temperatures. Therefore, County residents should concentrate on personal protection and are urged to be cautious, but not curtail their outdoor activities.
 
The number of cases is expected to increase, since additional reports have been received and confirmation is anticipated in the coming days.  Statewide, 2012 human case data, including cases by county, are provided on the Illinois Department of Public Health WNV website.
 
Approximately one in five people who are infected with West Nile virus will develop symptoms such as fever, headache, body aches, joint pains, vomiting, diarrhea, or rash.  Less than 1 percent will develop a serious neurologic illness such as encephalitis or meningitis (inflammation of the brain or surrounding tissues).

People over 50 years of age and those with certain medical conditions, such as cancer, diabetes, hypertension, kidney disease, and organ transplants, are at greater risk for serious illness.

There are no medications to treat, or vaccines to prevent, West Nile virus infection.  People with milder illnesses typically recover on their own, although symptoms may last for several weeks.  In more severe cases, patients often need to be hospitalized to receive supportive treatment, such as intravenous fluids, pain medication, and nursing care.  Anyone who has symptoms that cause concern should contact a health care provider.
