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.

On Wednesday, doctors said Francis’ kidney failure “has subsided” and a CT scan of his chest “showed a normal progression of the lung inflammation.” Blood tests also confirmed the pope’s health is improving.

Pope Francis is still critically ill as he battles double pneumonia, but his condition has shown a "slight improvement", the Vatican said on Monday.
