Amber Vinson, a Dallas nurse who contracted Ebola while caring for Thomas Eric Duncan, is now free of the virus, according to her family.

Vinson arrived at Emory University Hospital last week for treatment. As of Tuesday night, officials with the hospital and the Centers for Disease Control and Prevention Ebola were not able to detect Ebola in Vinson's body, her family said in the statement.

Vinson "has also been approved for transfer from isolation," the family's statement read.  "We all know that further treatment will be necessary as Amber continues to regain strength, but these latest developments have truly answered prayers and bring our family one step closer to reuniting with her at home," her mother, Debra Berry, said in a statement.

As a nurse at Texas Presbyterian Hospital in Dallas, Vinson helped treat Duncan, a Liberian national who eventually succumbed to the disease. Vinson flew on a commercial flight from Cleveland to Dallas a day before being diagnosed. She had boarded that flight after telling the CDC that she was running a 99.5 degree temperature; the CDC didn't prohibit her from boarding, The Post has reported. But CDC Director Thomas Frieden later said she shouldn't have been boarding any flights given her possible exposure to the virus.

Nina Pham also became infected with Ebola while working as a nurse at the Dallas hospital, and she has since been transferred to the National Institutes of Health in Maryland. Pham's condition was upgraded from "fair" to "good" on Tuesday.

And on Tuesday, NBC freelance cameraman Ashoka Mukpo was declared Ebola-free. He contracted Ebola in Liberia and was treated at Nebraska Medical Center.

President Obama spoke to healthcare workers at the Dallas hospital on Wednesday. According to the White House, Obama "conveyed his thoughts and prayers to their two colleagues who were infected with Ebola and wished them a speedy recovery."
