LAS VEGAS (AP) - Health officials say a they've confirmed a sixth human case of West Nile virus in southern Nevada.
The Southern Nevada Health District says Tuesday that a 38-year-old man has been diagnosed with the less serious form of the illness.
West Nile has already been blamed in the death of 75-year-old woman in Clark County in recent weeks, and four other people have been diagnosed with the virus this year.
Four deaths in Clark County have been linked to West Nile virus since 2003.
The health district has identified West Nile-positive mosquitoes in the 89145 and 89107 ZIP codes.
