"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," spokesman Jim McGrath said. "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 -- who served as the nation's 41st president from 1989-1993 -- was initially hospitalized on November 23 with a bronchitis-like cough.
