The second Dallas nurse diagnosed with Ebola appears to have beaten the virus while receiving care at Emory University Hospital in Atlanta.

The nurse, Amber Vinson, is “regaining strength,” and health officials are “no longer able to detect virus in her body,” her mother said in a statement.

{mosads}The announcement makes Vinson the sixth American to recover from Ebola, since the epidemic began.

On Tuesday, NBC cameraman Ashoka Mukpo tweeted that he was virus-free after three consecutive days of negative tests.

Mukpo contracted Ebola on location in Liberia and was receiving treatment at Nebraska Medical Center in Omaha.

The only other American known to be battling Ebola is Dallas nurse Nina Pham, who, along with Vinson, treated Thomas Eric Duncan, the first person diagnosed with Ebola in the United States.

The other three Americans to recover are Dr. Kent Brantly, Dr. Richard Sacra and Nancy Writebol. All three were working on medical teams in Liberia when they contracted Ebola. 

Brantly and Writebol were treated at Emory, while Sacra recovered at Nebraska Medical Center.

Pham is receiving care at the National Institutes of Health in Bethesda, Md., where her condition was upgraded from “fair” to “good” on Tuesday.

Duncan, the index patient in the U.S., died on Oct. 8.

Vinson’s mother said the family is “ecstatic” that health officials no longer detect the virus in her body. Vinson has been approved for transfer from medical isolation for the rest of her recovery, the statement said.
