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

Pope Francis is responding well to the treatment for double pneumonia and has shown a "gradual, slight improvement" in recent days, the Vatican said Saturday. But his doctors have decided to keep his prognosis as guarded, meaning that he's not out of danger yet.
