According to his spokesman, his fever is gone, but it doesn't sound like George H.W. Bush is doing too hot at the moment. He's currently in intensive care at a Houston hospital. More details from the AP:

A spokesman says former President George H.W. Bush is in the intensive care unit at a Houston hospital.

Bush’s spokesman, Jim McGrath, said late Wednesday that the former president was admitted to the ICU on Sunday at Methodist Hospital, “following a series of setbacks including a persistent fever.”

McGrath says Bush is alert and conversing with medical staff, and that doctors are cautiously optimistic about his treatment.

That’s all they details they’re offering for now. Good luck as far as getting better, George.
