A Texas nurse who caught Ebola after treating an infected Liberian man is to be discharged from hospital later.
Amber Vinson, 29, is expected to make a statement as she leaves Emory University Hospital in Atlanta, Georgia, at 1pm (5pm GMT) on Tuesday.
The facility announced last week that doctors could no longer detect the virus in her body.
Ms Vinson was one of two nurses diagnosed after caring for Thomas Eric Duncan, who died of the disease in Dallas on 8 October.
The other nurse, Nina Pham, was released last week from a federal hospital in the Washington DC area.
Ms Vinson’s clean bill of health means there is only one person currently being treated for Ebola in the US, a New York doctor.
Craig Spencer, 33, remains in a serious but stable condition at Bellevue Hospital in Manhattan.
Meanwhile, a nurse who threatened to sue after she was quarantined in New Jersey over the weekend is back in her home state of Maine.
It is still unclear how long Kaci Hickox, who has shown no symptoms of Ebola since returning from West Africa, will remain in confinement.
Maine health officials announced she would be isolated at home for 21 days, but her lawyer said he expected the seclusion to last only for the “next day or so”.
The attorney, Steve Hyman, said she “deserves to be honoured, not detained”.
He added that Ms Hickox was at an “undisclosed location”. There was no sign of activity at the Fort Kent home of her partner, a nursing student, reported the Associated Press.
The governors of New York and New Jersey have defended their decisions on Friday to impose mandatory 21-day quarantine for medical workers returning from West Africa.
Federals officials say such a policy is unnecessary.
But the US Army has begun isolating soldiers returning from an Ebola response mission in West Africa, even though they have shown no symptoms of infection.
Among those being kept in isolation is an Army two-star general and 11 of his staff at a base in Italy.
On Tuesday, Australia suspended entry visas for people from Ebola-affected countries in West Africa in an attempt to keep out the disease.Ebola has killed more than 4,900 people and infected more than 10,000 since the beginning of the year, according to the World Health Organization.
