U.S. Secretary of State Hillary Clinton remains in the hospital on Monday (December 31) after she was admitted with a blood clot linked to a concussion she suffered earlier this month.
The State Department said in a statement that Clinton was admitted on Sunday (December 30).
65-year-old Clinton, has been out of the public spotlight since mid-December, when officials said she suffered a concussion after fainting due to a stomach virus contracted during a trip to Europe.
"In the course of a follow-up exam today, Secretary Clinton's doctors discovered a blood clot had formed, stemming from the concussion she sustained several weeks ago," State Department spokesman Philippe Reines said in a statement.
"She is being treated with anti-coagulants and is at New York-Presbyterian Hospital so that they can monitor the medication over the next 48 hours," Reines said. "They will determine if any further action is required."
U.S. officials have since described her condition as improving and played down suggestions that it was more serious.
