KNOXVILLE, Tenn. (WVLT) -- The family of a Seymour nurse who worked in Knoxville says complications from H1N1 led to her death.

Tina Vick, 43, was a wife and mother of two.

She was healthy up until she came home from work with a fever of 102 degrees about two weeks ago.

Today, her mom told Volunteer TV that after four days with a fever, she went to UT Medical Center but she never recovered.

Tina Vick was in the hospital for a week and five days.

Her mom says she also got double pneumonia and was on a ventilator.

Toward the end, she seemed to improve-- her fever went away, but then she suddenly got worse than before.

Vick died on Saturday.

Her abrupt death has been hard on everyone close to her.

Her co-workers at Select Specialty Hospital at St. Mary's say they're shocked.

Vick's mom says that Tuesday is Tina's older son's birthday. He turns 15.

The younger son turns 12 next month.

Tina Vick's death is not a confirmed case of H1N1, swine flu, and the double pneumonia is believed to have played a role in her death as well.

Symptoms for both swine flu and the seasonal flu are the same.

They include fever, headaches, extreme tiredness, a dry cough, sore throat, runny or stuffy nose, and muscle aches.

Stomach symptoms can occur in children.
