ALLIANCE, Neb. -- Health officials in northwest Nebraska say they've found West Nile Virus in a dead bird from Box Butte County, a sign the disease is still present in the area. It's the first infected bird found in Nebraska this year. West Nile is passed through the bite of a mosquito that has picked up the virus by feeding on an infected bird. Public Health officials say it means the virus continues to pose a risk. The Nebraska Department of Health and Human Services says 22 human cases of West Nile Virus are confirmed in Nebraska this year.
