Doctors on Friday said the 88-year-old Francis is "not out of danger" ​and that the main threat facing him would be the onset of sepsis.

The Vatican is carrying on with its Holy Year celebrations without the pope. Pope Francis remains hospitalized with pneumonia and a complex respiratory infection.

Pope Francis, who is being treated in hospital for double pneumonia, will not appear in public on Sunday to lead his usual prayer with pilgrims for a second consecutive week, the Vatican said.
