Phoenix, ARIZONA (BNO NEWS) – A 57-year-old woman became Arizona’s second swine flu death last week, officials said on Tuesday afternoon.

“It was a 57-year-old female from Pinal County, Arizona,” said Alia Maisonet, who is a spokeswoman for the Gila River Indian Reservation. The woman, who’s identity is not being released, was admitted to a hospital outside the reservation after she complained of flu-like symptoms.

Shortly after her hospitalization last week, the woman passed away and tests later confirmed she did in fact have swine flu at the time of her death. Officials refused to provide details on the exact day she died but did say the woman had a pre-existing medical condition. “She had a compromised immune system,” the spokeswoman said. “Confirming whether or not she actually passed away from H1N1 flu is hard to tell because of the pre-existing medical condition.”

The Arizona Department of Health Services and the Centers for Disease Control and Prevention (CDC) also confirmed that a second person with swine flu had passed away. Both had no additional information on the case.

On May 14, a woman suffering from a lung condition and swine flu became the first Arizona citizen to die in relation to the disease that killed dozens in mainly Mexico and the United States.
