West Nile Virus remains a threat

The West Nile Virus (WNV) spread by mosquitoes remains a potential threat in Wyoming as warmer weather arrives across the state, according to the Wyoming Department of Health.

“West Nile virus can sometimes cause serious illness,” said Emily Thorp, surveillance epidemiologist with the Wyoming Department of Health. “Because mosquitoes spread the virus by feeding on infected birds and then biting people, other birds and animals, preventing mosquito breeding and avoiding bites are important.”

According to the Wyoming Department of Health, in Wyoming last year seven human WNV cases were reported, and since WNV first appeared in Wyoming in 2002, the annual numbers of reported human cases have ranged from two with no deaths to 393 and nine deaths.

Thorp recommended the “5D’s” of prevention:

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 outdoors or when mosquitoes are most active. Clothing should be light-colored and made of tightly woven materials.

4. DRAIN- Mosquitoes breed in shallow, stagnant water. Reduce the amount of standing water by draining and/or removing it.

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