San Diego County health officials say a 20-year-old woman has died from the swine flu.
The announcement on Tuesday marks California's seventh death from the disease.
The county Health and Human Services Agency says the woman died Monday in a hospital emergency room shortly after developing flu symptoms. Public health officials say it is the first confirmed swine flu death in the San Diego area.
County Public Health Officer Wilma Wooten says the woman was apparently healthy just before going to the emergency room to be evaluated. Her name has not been released.
Wooten says the circumstances of the woman's death are not unusual for a swine flu case, noting that there is no immunity to the disease.
