DALLAS (AP) Dallas County has reported its 11th death blamed on the West Nile virus.

The county's health and human services department said Tuesday the latest victim lived in north Dallas, but did not immediately have further details.

Texas, especially around the Dallas area, has seen the bulk of the nation's cases. More than 260 human cases of the virus have been confirmed in Dallas County, which recently completed two sweeps using aerial spraying to combat mosquitoes.

Mosquitoes spread the virus from birds to people. One in 150 infected people develop severe symptoms including neck stiffness, disorientation, coma and paralysis.
