Secretary of State Hillary Rodham Clinton, already ill with a virus, is now recovering from a concussion sustained after fainting, her office said Saturday.
Clinton "will continue to be monitored regularly by her doctors," said a statement from spokesman Philippe Reines.
"At their recommendation," Reines added, "she will continue to work from home next week, staying in regular contact with Department and other officials. She is looking forward to being back in the office soon."
In explaining her injury, Reines said: "While suffering from a stomach virus, Secretary Clinton became dehydrated and fainted, sustaining a concussion."
The virus had forced Clinton to skip a planned trip this seek to North African and the Persian Gulf.
Clinton, 65, is expected to announce her retirement from the State Department soon.
