US Ebola patient in 'good' condition

An American healthcare worker who fell ill with Ebola in Sierra Leone has improved and is now listed in good condition at a hospital near the US capital, officials said Tuesday.

The man, whose identity has not been revealed, "has improved from fair to good condition," said a statement from the National Institutes of Health Clinical Center.

He worked for the global medical charity Partners in Health, and was evacuated from Sierra Leone on March 14 and brought to the NIH's Clinical Center in Bethesda, Maryland for treatment.

The NIH is the premier medical research center in the United States.
