Nina Pham, one of the two nurses who contracted Ebola in Dallas, is expected to be moved to a National Institutes of Health isolation unit in Bethesda, Maryland, a federal official with direct knowledge of the plans told NBC News on Thursday.
The NIH facility has one of four biocontainment units in the United States.
A second nurse who tested positive, 29-year-old Amber Joy Vinson, has been transferred to a biohazard infectious disease center at Emory University Hospital in Atlanta.
Pham and Vinson were involved in providing care to Thomas Duncan, who died of Ebola last week.
