CARSON, Calif. -

Authorities say a Los Angeles County man infected with the West Nile virus has died and health officials are trying to determine whether the illness caused his death.  

The Long Beach Press-Telegram says the 78-year-old Carson man died Tuesday night.

His family says he was hospitalized two weeks earlier with symptoms that included slurred speech, pain and memory loss.    

Five cases of the mosquito-borne disease have been reported this year in the county.
