LAS VEGAS (AP) - Health officials say they're investigating the first "probable" human case of West Nile virus this year in the Las Vegas area.
The Southern Nevada Health District says a 50-plus-year-old man is believed to have the most serious form of West Nile virus. The man's identity isn't being made public.
Last week, the Nevada State Health Division reported the first human case of case West Nile virus in Lyon County, and said that mosquitoes with West Nile virus were found in Lovelock in Pershing County.
Twelve human cases were reported in Nevada in 2007, including three in Clark County.
Most people who are infected have no symptoms or what appears to
be a mild flu. But the virus can cause serious illness for the elderly and people with weakened immune systems.
