U.S. Secretary of State Hillary Clinton has suffered a concussion after fainting at home, according to the State Department.

A statement Saturday from Philippe Reines, deputy assistant secretary of state, says that while suffering from a stomach virus, Clinton became dehydrated and fainted.

Reines says she is recovering at home. He says at the recommendation of her doctors, she will continue to work from home next week, while staying in regular contact with State Department and other officials.

Clinton canceled plans this week to travel to the Middle East and north Africa because of her stomach virus.

The secretary of state and former U.S. first lady is 65 years old.
