West Nile virus has been found in mosquitoes trapped in Lancaster County.

The county health department said Wednesday that the mosquitoes were trapped in early July.

No cases of the disease have been reported in the county so far this year.

Last year 12 cases were reported in the county.

West Nile is spread by the bite of a mosquito that has fed on an infected bird.

There were 146 human cases of the disease reported in Nebraska last year, including three deaths.

Experts say that fewer than one out of 150 people who are bitten by an infected mosquito and becomes infected will get seriously ill.
