The number of confirmed human cases of West Nile virus in California continues to rise.
Health authorities say the number of confirmed human cases of the virus rose more than 46 percent in a week.
And the number of people killed by the mosquito-borne illness in California now
stands at nine.
The two latest reported deaths both occurred in San Bernardino County, an 88-year-old man in Loma Linda and an 82-year-old man from the city of San Bernardino.
Both men had pre-existing medical conditions that weakened their immune systems and made them more vulnerable to the virus.
State health authorities have now recorded 277 West Nile infections.
Four of the confirmed West Nile deaths have occurred in Los Angeles County. The others were in San Bernardino and Orange counties.
