West Nile Season Starts Early According to WDH

Written by on June 11, 2019

West Nile virus may be off to an earlier than usual start in Wyoming this year, with the state’s first case involving a Campbell County adult already reported, according to the Wyoming Department of Health
In 2018, WDH was notified of four WNV cases in Wyoming, including one death in Goshen County. Since the disease first reached Wyoming in 2002, the number of reported human cases has varied widely from year to year.
Clay Van Houten — Infectious Disease Epidemiology Unit Manager with WDH said 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.

The “5 D’s” of West Nile virus prevention include:

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 eucalyptus can also be effective.
