CHEYENNE, Wyo. — Wyoming has had a relatively easy West Nile season, thanks in part to the drought.
Four cases of West Nile virus have been confirmed in the state in 2012. No one has died.
At least 40 people have died from the virus in Texas.
The environmental supervisor for the Cheyenne-Laramie County Health Department, Roy Kroeger, said there aren't huge populations of mosquitoes because it's been so dry.
A man from Crook County was the first person confirmed to have contracted West Nile virus this year in Wyoming. Two Goshen County men were infected, and a man from Teton County also contracted West Nile but he may have been exposed to it in another state.
West Nile is blamed for two deaths in Colorado this summer.
