AMERICA: Former president George Bush Snr spent Christmas in a Texas hospital after developing a fever and weakness following a month-long, bronchitis-like cough.

The 88-year-old was originally expected to be out in time to spend the holiday at home, but that changed after Mr Bush developed a fever.

His spokesman said: "Doctors still say they are cautiously optimistic, but every time they get over one thing, another thing pops up."

The spokesman said the cough that initially brought Mr Bush to the hospital on November 23 is now evident only about once a day, and the fever appears to be under control.

However, doctors are still working to get the right balance in Mr Bush's medications.

No discharge date has been set.

Mr Bush's son, George W Bush, president from 2001-09, has been among visitors at the hospital.
