Pope Francis left Rome’s Gemelli hospital on March 23, under doctors’ orders to observe a two-month period of rest. In particular, Francis was to abstain from strenuous meetings and gatherings with groups of people.

His discharge from the Gemelli was a surprise, especially since doctors had said just the day before it was announced, that there was no date set for his return to the Vatican.

The 88-year-old pontiff was admitted to the hospital on Feb. 14 because of “acute respiratory failure” due to a polymicrobial respiratory infection, meaning it had various components, including viral, bacterial, and fungal infections that quickly became full-blown double pneumonia.
