(CNN) -- A second Dallas nurse who contracted Ebola is now free of the virus and was released from the Atlanta hospital where she's been treated, the hospital said Tuesday.
Amber Vinson spoke publicly for the first time at a news conference announcing her discharge, which comes about two weeks after her diagnosis, Atlanta's Emory University Hospital said.
She said she is "grateful to be well,” thanked God for giving her the hope and strength to fight, and also thanked former Ebola patients Dr. Kent Brantly and Nancy Writebol for their donations of plasma to her and other patients.
Vinson was one of two Dallas nurses who contracted Ebola after treating Liberia citizen Thomas Eric Duncan, the first person to be diagnosed in the United States with Ebola. Duncan, who had symptoms after flying from Liberia to Texas in September, was admitted to Dallas' Texas Health Presbyterian Hospital but died on October 8.
The other nurse, Nina Pham, was treated at a National Institutes of Health facility in Maryland before being declared Ebola-free on Friday. She was discharged from the hospital that day and met President Barack Obama at the White House before returning home.
Ebola has killed more than 4,900 people, mostly in Liberia, Sierra Leone and Guinea, in what health officials call the worst outbreak of the disease in history.
