Wyoming West Nile Virus Case Count Up to Seven

With six new confirmed cases over the last week, seven Wyoming residents have been found to be infected with West Nile virus so far this year, according to the Wyoming Department of Health.

Three cases have been from Fremont County, two from Crook County, one from Natrona County and one from Campbell County. Four of the infected adults are male and three are female, with ages between 24 and 63. The dates of reported onset of symptoms range from mid June to mid July.

West Nile virus (WNV) is a mosquito-borne disease that can cause a potentially serious illness in humans. Mosquitoes spread the virus after they feed on infected birds and then bite people, other birds and animals.

“With the recommended measures that people can take to protect themselves, West Nile virus is largely a preventable disease,” said Dr. Tracy Murphy, state epidemiologist with the Wyoming Department of Health.

Murphy noted that Wyoming’s typical peak transmission season has not yet been reached. “Everyone should be cautious, regardless of where they live or their past medical history,” he said.

The “5 D’s” of preventing West Nile Virus are:
1) DAWN and 2) DUSK - Most mosquito species prefer to feed at dawn or dusk, so avoid spending time outside during these times.

3) DRESS - Wear shoes, socks, long pants, and a long-sleeved shirt when spending time outdoors or when mosquitoes are most active. Clothing should be light-colored and made of tightly woven materials to keep mosquitoes away from the skin.

4) DRAIN - Mosquitos breed in shallow, stagnant water. Reduce the amount of standing water in or near your property by draining and/or removing it.

5) DEET - Use an insect repellent containing DEET (N, N-diethyl-m-toluamide). Products containing DEET should be used properly. When using DEET, be sure to read and follow the instructions on the product’s label. Avoid excessive use or over-application. In most circumstances, products with 10 to 35 percent DEET provide adequate protection for adults. Spray clothing with repellents containing permethrin or DEET because mosquitoes can bite through thin clothing. Permethrin should not be used on bare skin. Another insect repellent, Picaridin (KBR 3023), is also highly effective.
