For the first time since Pope Francis was hospitalized in mid-February, the Vatican press office released a photograph of him March 16; the image shows him concelebrating Mass that morning in the chapel of his suite of rooms at Rome's Gemelli hospital.

Pope Francis is registering new slight improvements in his monthlong treatment for pneumonia in both his lungs, the Vatican said Monday, as it also provided some details on the first photo of the pope released since his hospitalization.
