CARSON CITY, Nev. (AP) - West Nile virus is turning up in more mosquitoes tested by the Nevada Department of Agriculture.

The animal disease laboratory on Friday reports 42 mosquito samples from seven Nevada counties have tested positive for the disease.

Positive results were found in samples taken from Carson City, Clark, Churchill, Douglas, Elko, Lyon and Washoe counties.

People bitten by infected mosquitoes can suffer flu-like symptoms. Extreme cases can lead to death.

The U.S. Centers for Disease Control and Prevention says more than 13,000 people have been seriously ill and about 1,200 have died since 1999.

So far this year seven human cases have been reported in Nevada - six in Clark County and one in Douglas.

There is no vaccine for humans. Horse owners should update their animal's vaccinations.
