CASPER, Wyo. — The Wyoming Department of Health has confirmed a case of West Nile virus in a Natrona County resident.

“Historically we’ve seen reports of WNV cases trickle in through September,” department spokeswoman Kim Deti said in an email on Friday, Sept. 20.

She adds that cases of West Nile virus occur during mosquito season which lasts from the summer through the fall.

“The type of mosquitoes that carry WNV often bite form dusk to dawn,” Deti adds. “Most people infected with WNV don’t have symptoms.”

“Among those who become ill, symptoms include fever, headache, body aches, skin rash and swollen lymph nodes. A very small number develop West Nile neuroinvasive disease with symptoms such as severe headache, fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions and paralysis.”

Deti says that people can do some things to protect themselves from the virus. She calls these the “‘5 D’s’ of West Nile virus prevention.

Those include the following:

1) DAWN and 2) DUSK – Mosquitos 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 outdoors. Clothing should be light-colored and made of tightly woven materials.

4) DRAIN – Mosquitos breed in shallow, stagnant water. Reduce the amount of standing water by draining and/or removing.

5) DEET – Use an insect repellent containing DEET (N, N-diethyl-m-toluamide). When using DEET, be sure to read and follow label instructions. Other insect repellents such as Picaridin (KBR 3023) or oil of lemon eucalyp¬tus can also be effective.
