"Following a series of setbacks including a persistent fever, President Bush was admitted to the intensive care unit at Methodist Hospital on Sunday where he remains in guarded condition," said Jim McGrath, a Bush family spokesman. "Doctors at Methodist continue to be cautiously optimistic about the current course of treatment. The President is alert and conversing with medical staff, and is surrounded by family."
Bush, 88, has been hospitalized in Houston for more than a month with a lingering cough. He spent Christmas in his hospital room surrounded by several members of his family, including his wife, Barbara.
Doctors are running tests and treating the fever with Tylenol, but still have not determined a cause. Doctors have also put the former president on a liquid diet, although a spokesman wouldn't say why.
