An elderly man in Northern California is the latest person to have West Nile virus, adding to the six cases reported this week in Los Angeles County and Sacramento, state officials said.

An elderly resident in Glenn County was infected with West Nile, which is carried through mosquitos and can be fatal, said Dr. Ron Chapman, director of the California Department of Public Health.

The person was hospitalized, but is recovering. The case was a reminder that the public must take precautions against mosquito bites, Chapman said.

"West Nile virus activity is greatest during the summertime," he said.

To date in 2013, West Nile virus has been detected in 31 of the 58 California counties.

Five others were infected across the LA County, including the South Bay and San Fernando and San Gabriel valleys, the Los Angeles County Department of Public Health said. (Source: KNBC)
