Mother of two dies just day after flu diagnosis

Murrieta, the mother of a 2-year-old and a 6-month-old, was healthy before the sudden illness, with no pre-existing health conditions, according to family. She first experienced symptoms Sunday, when she left work early. On Monday, she went to urgent care, where she was diagnosed with the flu and sent home with medications. She was admitted to the hospital Tuesday morning as her symptoms became more severe and she was having difficulty breathing, KSAZ reported.

At the hospital, doctors performed tests and diagnosed Murrieta with pneumonia. She was placed on a ventilator, but her heart stopped. The efforts to resuscitate her were unsuccessful.

While family members said Murrieta didn't get a flu shot, early results show this year's formula may not be very effective at combatting this year's flu strains.
