ATLANTA - Federal officials say two American aid workers who contracted Ebola in Africa will be flown into a metro Atlanta military base.

The Pentagon's press secretary, Navy Rear Adm. John Kirby, said Friday that a private-chartered aircraft will be arriving at Dobbins Air Reserve Base with patients evacuated from Africa. The patients will then be taken to medical facilities.

Kirby says officials in the U.S. State Department asked the military to provide an airfield for the arrival.

Details about the patients' movements were not entirely clear Friday. Kirby said he did not know when the patients would arrive.

At least one of the Americans was expected to be treated at Atlanta's Emory University Hospital, which has a specialized isolation unit. Hospital officials have declined to identify which patient will be treated there.
