The second of two Dallas nurses who contracted Ebola was declared free of the disease and on Tuesday was released from Emory University Hospital in Atlanta.

Amber Vinson caught the virus while she was caring for Thomas Eric Duncan at Texas Health Presbyterian Hospital, according to a report from CNN. Duncan was infected with Ebola while he was in Liberia in September, but didn't show symptoms of the disease until he was back in Dallas.

Duncan died on Oct. 8. Vinson and Nina Pham both got the disease after caring for Duncan. Pham was treated at the National Institutes of Health in Maryland and was released from the hospital on Friday.

Vinson spoke briefly at a press conference celebrating her clean bill of health, thanking God for helping her fight the disease, Reuters reported. Her grandparents were in attendance and, after she spoke, Vinson hugged each member of the team that took care of her.

Dr. Bruce Ribner, who led Vinson's care at Emory, said the nurse "has recovered from her infection with Ebola virus, and she can return to ... her community and to her life" without any concerns of transmitting the virus.

Vinson originally was hospitalized in Dallas, but was transferred to Emory, which has had success treating four Ebola patients. Ribner said his team has learned a lot from its experience treating the disease.

Doctors at Emory have learned about managing fluids and electrolytes, and have found that they still can treat Ebola patients aggressively even when they're on dialysis. Ribner said Emory is sharing these lessons with other doctors and facilities fighting the disease in West Africa and in the U.S.

The Ebola outbreak started earlier this year in Guinea and is the worst on record. More than 4,900 people have died in West Africa and thousands more are sick. The World Health Organization has said that the disease is killing 70 percent of those infected in West Africa.

With Vinson's release, only one person is being treated for Ebola in the U.S. Dr. Craig Spencer, who caught the disease in West Africa, is being treated at a New York City hospital. He is in serious, but stable condition.
