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.

VATICAN CITY - Pope Francis is showing a "good response" to his hospital treatment for double pneumonia and his overall condition is gradually improving, the Vatican said on Saturday. Francis, 88, has been in Rome's Gemelli hospital for more than three weeks with a severe respiratory infection that has required continuously evolving treatment.

Pope Francis "had a tranquil night and woke shortly after 8 a.m.," the Vatican said, coming a day after he made his first public comments since being hospitalized.
