All of Kansas at moderate risk for West Nile virus

WICHITA, Kan. (KAKE) -

Kansas health officials report the entire state is at moderate risk for West Nile virus infections. 

The Kansas Department of Health and Environment said in its weekly Surveillance and Transmission Risk Report that every county in Kansas is under a moderate risk, meaning there is a moderate probability of being bitten by a mosquito carrying West Nile.

No human cases have been reported in Kansas as of May 25

KAKE's sister station KTEN reports the Oklahoma State Department of Heaths confirmed three human cases of the virus on Friday. The cases were reported in Canadian, Tulsa and Grant counties. Grant County shares the Kansas state line with Harper and Sumner counties. 

West Nile virus can be spread to people through mosquito bites, but it is not spread from person to person. About one in five people who are infected develop a fever and other symptoms. About one out of 150 infected people develop swelling of the brain or brain tissue, that in some cases, can result in death.

There are no vaccines or medications to treat West Nile in humans, the KDHE said. People who have had the virus before are considered immune.

KDHE recommends the following prevention measures:

  • Visit the KDHE WNV website weekly to learn about the current WNV risk level.
  • When you are outdoors, use insect repellent containing an EPA-registered active ingredient on skin and clothing, including DEET, picaridin, oil of lemon eucalyptus, or IR3535. Follow the directions on the package.
  • Many mosquitoes are most active at dusk and dawn. Be sure to use insect repellent and wear long sleeves and pants at these times, or consider staying indoors during these hours.
  • The elderly or those with a weakened immune system should consider limiting their exposure outside during dusk and dawn, when the Culex species mosquitoes are most active.
  • Make sure you have good screens on your windows and doors to keep mosquitoes out.
  • Get rid of mosquito breeding sites by emptying standing water from flower pots, buckets and barrels. Change the water in pet dishes and replace the water in bird baths weekly. Drill holes in tire swings so water drains out. Keep children's wading pools empty and on their sides when they aren't being used.
  • Horses can also be infected with WNV. Talk with your veterinarian about vaccinating your horse to protect them against WNV.
