2nd Dallas Nurse Ebola-Free, Thanks Hospital, Family and God

Amber Vinson leaves Emory University Hospital Ebola-free.

"I’m so grateful to be well," Vinson said.

"First and foremost, I want to thank God," she said, adding that God gave her the “hope and strength to fight” Ebola.

Vinson also thanked her mother, fiancé and extended family for visiting.

"Family played such an important role in my recovery," she said, "by being there every minute, every day, even though you couldn't be close."

She also thanked health workers who cared for her and stressed the importance of not losing "focus" on the fight against Ebola in West Africa. Before she left, Vinson hugged more than a dozen staff members as they smiled, laughed and wished her a safe trip home to Texas.

President Obama spoke to Vinson on the phone following her discharge, he said during brief remarks this afternoon.

He, too, stressed the importance of continuing to fight Ebola in Liberia. Alluding to the mandatory quarantines several states said they would impose on health workers returning to the United States from West Africa, Obama said it was important to make judgments based on science and not put up any additional barriers for people who volunteer to fight Ebola.

"America, in the end, is not defined by fear," Obama said. "It's not who we are. Americans are defined by possibilities. And when we see a problem and we see a challenge, then we fix it."

Dr. Bruce Ribner, medical director of Emory University Hospital's Infectious Disease Unit, said Vinson was the hospital's fourth Ebola patient since the outbreak began.

"As fellow members of the health care community, we deeply admire Ms. Vinson’s courage and dedication in caring for a patient with a serious communicable disease," Ribner said. "Nurses are on the front lines 24 hours a day in treating our patients and it is their skill, their knowledge and their passion for healing that makes one of the critical differences in caring for our patients."

Vinson took a flight to Ohio and returned to Dallas in the days before she, too, was diagnosed with Ebola on Oct. 15. That evening, she was flown to Emory University Hospital. Passengers on both of Vinson's flights were notified about the ordeal.

Meanwhile, Dr. Craig Allen Spencer, who tested positive for Ebola last week in New York City a week after traveling home from treating Ebola patients in Guinea, remains in serious but stable condition at Bellevue Hospital in Manhattan.

Another little boy tested negative for Ebola at Bellevue Monday after recently traveling from Guinea and will be removed from isolation, officials said.
