Hillary Clinton 'thrilled to be back' after health scare
US Secretary of State Hillary Clinton has said she is "thrilled to be back" at work after spending a month recuperating from a series of ailments.
Mrs Clinton was treated in a New York hospital in early January for a blood clot between the skull and the brain.
In December she fell and suffered a concussion after she became dehydrated as a result of a stomach virus.
Mrs Clinton, 65, is due to stand down in the near future and Massachusetts Senator John Kerry has been nominated to replace her as America's top diplomat.
