Dr. Wilma Wooten said on Tuesday that the victim is a 20-year-old woman. "Prior to this illness, the individual was apparently healthy and had not traveled,'Wooten told reporters outside the County Heath and Human Services building.
Health officials wouldn't reveal the woman's identity or where she lived, only that she was a San Diego resident. They said on Saturday she was in good health, but on Sunday that quickly changed as she began to experience flu-like symptoms.
On Monday, she went to a local emergency room and within hours died after suffering severe respiratory problems.
Shortly before 5.pm. on Tuesday, Health officials confirmed the woman had the H1N1 virus, or Swine Flu.
Dr. Wooten said it's not unusual how quickly the woman died. "With this being a novel H1N1 virus, people do not have immunity so even apparently healthy individuals may have complications and in this case apparently die from the illness."
People who have been exposed to the victim are being treated with Tami-flu.
The victim is the seventh person in California to die from a Swine Flu related illness. Nationally, the death toll has reached 44.
Almost 1,100 Californians have been diagnosed with the H1N1 or swine flu, and seven of those have died, according to the Centers for Disease Control.
"We expect to see more illness, more complications and we expect to see more deaths associated with this influenza virus,"Dr. Wooten warned.
She also said people need to cover their mouths when they cough and they should wash their hands often, especially in public places "If you are sick, we want you to stay home and not travel, not go to school and not go to work."
