The 88-year-old pope who has been hospitalized in Rome since February 14, did not have any further respiratory crises overnight but it would take a couple of days to make the latest assessment of his health, according to Vatican News. Newsweek has contacted the Vatican for comment.

The Vatican says Pope Francis has continued making decisions and is improving, but his two-week hospital stay poses uncomfortable, unanswered questions about Vatican decision-making.

Concerns over Pope Francis' health have mounted in recent years as have questions about his succession. Here's what we know.

The pope's condition remains stable yet guarded, with no ventilation needed but high-flow oxygen continuing as the Vatican monitors closely.

The Vatican said doctors had to put him on noninvasive mechanical ventilation following a coughing fit in which he inhaled vomit that needed to then be extracted.

The Vatican says Pope Francis’ respiratory tract infection is presenting a “complex clinical picture” that will require further hospitalization.

Vatican authorities said Monday that Pope Francis has a complex infection in his respiratory system and will require more targeted drug treatment.

Catholics in Rome gathered to pray outside the hospital where Pope Francis is being treated and remains in a 'critical' condition.

This was the first and only time a pope visited the Alamo City, drawing an estimated 350,000 people to his outdoor Mass at Westover Hills.
