Pope Francis is responding well to treatment and has shown a “gradual, mild improvement” in recent days as he remains in the hospital recovering from double pneumonia, the Vatican said Sunday.

“The night was quiet; the Pope is resting,” the Vatican said in a statement.

Francis, 88, was admitted to Rome’s Gemelli Hospital on Feb. 14 after a week-long bout of bronchitis worsened. Doctors first diagnosed the complex viral, bacterial and fungal respiratory tract infection and subsequently the onset of pneumonia in both lungs.

Canadian Cardinal Michael Czerny will preside over the Holy Year Mass on Sunday for the volunteers.

The pope has been using high flows of supplemental oxygen to help him breathe during the day and a noninvasive mechanical ventilation mask at night.
