FIRST HUMAN CASE OF WNV IN DUPAGE IN 2013

Mon September 23, 2013

The DuPage County Health Department reports the first human case of West Nile Virus (WNV) in DuPage County in 2013 is a male international traveler in his 70s who was hospitalized while visiting DuPage County. This individual also had travel outside Illinois during his exposure period.  He has been discharged and has resumed his travels.

WNV is transmitted to people by infected mosquitoes.  The best way to prevent WNV is to avoid mosquito bites:
 
·         Use insect repellents when you go outdoors.
          Avoid the outdoors during dusk to dawn, when the mosquitoes that transmit WNV are most active.
·         If outdoors, wear long sleeves and pants during dawn and dusk.
·         Install or repair screens on windows and doors.
·         Empty standing water from items outside your home such as flowerpots, buckets and kiddie pools.
 
Approximately one in five people who are infected with WNV 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 vaccines for humans or medications to treat WNV infection.

WNV activity generally decreases in the fall when cooler temperatures arrive and especially after the first frost of the season.
