With Pope Francis entering his fourth week in hospital, those working in the Apostolic Palace are grappling with the continuing uncertainty over the pope’s health. The same is true for everyone in the Vatican.

Pope Francis' condition is improving, but he still requires various in-hospital therapies, the Vatican said Saturday.

Pope Francis remains stable in hospital and a recent chest scan confirmed improvements in his condition, the Vatican said on Wednesday, in a further sign of progress as the 88-year-old pontiff battles double pneumonia.
