The update to Francis’s condition came Sunday in the written text of his regular Angelus prayer after he had been listed as “critical” on Saturday.

The announcement on Saturday evening indicated that Francis’ medical condition had become more complicated since an update from his doctors on Friday.

Pope Francis, battling double pneumonia, remains in a critical condition and his prognosis is still guarded because of the "complexity" of his clinical condition, the Vatican said on Sunday. The pope was admitted to Rome's Gemelli hospital on February 14 after having trouble breathing for several days and subsequently had pneumonia diagnosed in both lungs.
