An American doctor who was flown back to the US after contracting the deadly Ebola virus in Liberia is improving, a health official said.
Dr Kent Brantly continues to be treated at the Emory University Hospital in Atlanta after being flown back to the US from the West African nation on Saturday.
Dr. Tom Frieden, director of the US Centers for Disease Control, told CBS News: "It's encouraging that he seems to be improving. That's really important and we're hoping he'll continue to improve."
He added that it was too soon to predict whether Brantly would survive, but said it was unlikely that his wife and children, who left Liberia shortly before he began exhibiting symptoms, had contracted the disease.
His colleague Nancy Writebol who also contracted Ebola while working in the same facility as Brantly will be brought to the United States on a later flight because the medical aircraft is equipped to carry only one patient at a time.
