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.

ROME (AP) — Pope Francis is participating in the Vatican’s weeklong spiritual retreat from a Rome hospital as he continued his recovery on Monday from double pneumonia and looks ahead to the 12th anniversary of his election amid questions about what the future of his papacy might look like.

The 88-year-old isn’t out of the woods yet, however. Doctors are still cautious and have decided to keep him hospitalized for several more days to receive treatment, not to mention rehabilitation.
