ROME (AP) — Pope Francis entered the fifth week of hospital treatment for double pneumonia on Saturday with signs of recovery continuing on a positive trajectory.

The Vatican announced Friday that it would provide medical updates less frequently, in what it called a positive development. It also has ceased issuing brief morning advisories that the pope had slept well and was starting his day.

Doctors this week said the 88-year-old pope was no longer in critical, life-threatening condition, but have continued to emphasize that his condition remained complex due to his age, lack of mobility and the loss of part of a lung as a young man.

Francis was admitted to the hospital on Feb. 14 after a bout of bronchitis that made it difficult for him to speak. Doctors soon added a diagnosis of double pneumonia and a polymicrobial (bacterial, viral and fungal) infection.

The first three weeks of his hospitalization were marked by a rollercoaster of setbacks, including respiratory crises, mild kidney failure and a severe coughing fit.

But medical updates this week have focused on his continued physical and respiratory therapy, as well as the rotation from high-flow oxygen through nostril tubes during the day and a non-invasive ventilation mask at night to help ensure his rest. An X-ray this week confirmed that the infection was clearing.

With little more to report, doctors on Friday canceled a planned medical update. The next is to be issued later Saturday. Doctors have not indicated how much longer Francis will be hospitalized.

The pope this week participated in Lenten spiritual exercises from the hospital, which Vatican officials have said implied a lighter workload. He received a cake and hundreds of messages wishing him well on the 12th anniversary of his papacy Thursday.

The only public sign of life from the pope since his hospitalization was a recorded audio message thanking people for their prayers for his recovery in a weak and labored voice. It was played in St. Peter's Square for the faithful gathered for a nightly recitation of the rosary prayer.

For the last four Sundays, the traditional blessing that the pope delivers from a window overlooking St. Peter’s Square has been released as a text.
