The 88-year-old pope has remained stable, with no fever and good oxygen levels in his blood for several days, doctors said.

If the last few days are any guide, Francis will likely follow the Vatican’s spiritual retreat remotely while his physical and respiratory therapy continues.

Pope Francis' doctors on Monday lited a "guarded prognosis" though he will need to remain in the "hospital setting for a period of time" in the treatment of double pneumonia, the Vatican said.
