Pope Francis's condition was continuing to improve, the Vatican said Thursday (Feb 27), as the 88-year-old pontiff marked two weeks in hospital with pneumonia in both lungs.

The health of Pope Francis remains unclear as the faithful have gathered in St. Peter’s Square nightly to pray for his recovery. The 88-year-old pontiff was hospitalized almost two weeks ago, suffering from double pneumonia and mild renal insufficiency.

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.
