ROME (AP) — Pope Francis continued to improve from double pneumonia Thursday, the Vatican said, working from his hospital room and going to his private chapel to pray, though doctors said he needs more days of “clinical stability” before they revise their guarded prognosis.

Pope Francis, who is being treated in hospital for double pneumonia, slept well overnight and is resting, the Vatican said in a brief statement on Thursday. The 88-year-old pontiff was spending his 14th day in Rome's Gemelli hospital after coming down with a severe respiratory infection that triggered various complications.

After almost two weeks in hospital, Pope Francis appears to be on a slow road to recovery, according to the Vatican. "The pope slept well during the night" and is now resting, the Holy See said on Thursday morning.
