West Nile Virus Update on Confirmed and Unverified Presumptive Cases
One Presumptive Death from WNV Now Confirmed

The Kansas Department of Health and Environment (KDHE) Laboratory has confirmed two additional human cases of West Nile Virus (WNV) encephalitis or meningitis or acute flaccid paralysis (AFP) cases in the state. This brings the reported, confirmed case total to 78. The most recently confirmed cases include:

76 year old in Riley County – onset of symptoms 9/30
56 year old in Johnson County – onset 9/21

From commercial labs, KDHE has now received reports from 505 people in Kansas of unverified, presumptive positive WNV infection. One of the previously announced presumptive deaths from WNV was confirmed. The number of confirmed deaths is now three, and the number of presumptive deaths is now two.

West Nile Virus is transmitted to humans when a mosquito bites an infected bird and then bites a human. Symptoms of West Nile Virus can include headache, low-grade fever, and muscle aches, but in rare cases can result in serious illness causing swelling of the brain (encephalitis), swelling of the covering of the brain (meningitis), paralysis, or death. It is estimated that 1 in 150 persons infected with the West Nile Virus will develop a more severe form of the disease.
There have been 137 birds, 66 horses and 38 mosquito pools that have tested positive for WNV in Kansas so far this year as well.

KDHE recommends that everyone in Kansas take the following precautions to reduce their risk of contracting WNV:

• Use insect repellent containing DEET (according to label directions);
• Limit outdoor activities during dawn/dusk when mosquitos are most active;
• Wear protective clothing when outdoors whenever practical;
• Eliminate any stagnant pools of water on your property;
• Repair screens or other areas of your home where mosquitos might enter.
