PLANO, Texas (AP) - A suburban Dallas county has reported its fourth West Nile-related death and at least the 55th reported in Texas.

A Plano health department statement says a Plano resident is the Dallas suburb's second West Nile death. Collin County officials say the death is the fourth in the county, all of whom have been older than 80 years old and with other medical problems.

The death brings to at least 29 the number of West Nile deaths reported from the Dallas-Fort Worth metropolitan area.

Federal health officials say this is the nation's worst year for the mosquito-borne virus since it was discovered in New York 13 years ago. Texas has about half of the U.S. deaths from the illness.
