West Nile Discovered in Laramie County CHEYENNE, WY (wpr) - A Laramie County woman has tested positive for West Nile virus. It's the first confirmed case in the county this year.

The Cheyenne-Laramie County Health Department said Friday that the woman's case brings the statewide total of confirmed human cases of West Nile to nine this year.

Most people who contract West Nile don't develop symptoms. But people can become ill with fever, headache and swollen lymph nodes. In extreme cases, it can be fatal.

The disease is spread by mosquitoes. Health officials urge people to take precautions including wearing insect repellent and draining standing water where the insects can breed. © Copyright 2009, wpr
