A 72-year-old North Highlands man is the state's ninth death from West Nile virus this year.
Sacramento County health officials say the unidentified man developed encephalitis, one of the most serious forms the virus can take, and died yesterday.
Health officials are again reminding people to protect themselves against mosquitoes, which carry the virus and transmit it to humans when they're bitten.
Most people suffer no serious symptoms, but a few, particularly the elderly, develop serious diseases that can lead to death.
The state has recorded at least 147 cases of the virus this year.
