The Vatican has announced that Pope Francis is being treated for a “complex clinical situation” and will remain in hospital for as long as necessary.
The 88-year-old pontiff was admitted to Rome’s Gemelli hospital on February 14 to undergo treatment and tests for bronchitis.
On February 17, the Vatican said Pope Francis has a “polymicrobial infection” of his respiratory tract, which has required a change in his treatment.
A later update added that the Pope was “proceeding with the prescribed treatment” in a stable condition and did not have a fever. He also undertook some work and reading while in hospital on February 17.
“Pope Francis is touched by the numerous messages of affection and closeness that he has been receiving in recent hours,” a statement added.
“He especially wants to extend his thanks to those who are hospitalized at this time, for the affection and love they have expressed through drawings and messages of good wishes; he prays for them and asks that they pray for him.”
Before his admission last week, Pope Francis had bronchitis symptoms for several days and had delegated officials to read prepared speeches at events.

Vatican spokesman Matteo Bruni also told reporters on February 17 that the pontiff was in good spirits.
A short statement on his condition said: “All tests carried out to date are indicative of a complex clinical picture that will require appropriate hospitalization.”
The pontiff’s weekly general audience, which is usually held each Wednesday, has been cancelled for this week, the statement added.
Over the weekend, the Vatican said the Pope was stable and that he’d been told to have “complete rest” to aid his recovery.
Over the weekend he held a video call with the Holy Family Parish in Gaza, led by Father Gabriel Romanelli.
Pope Francis has been hospitalized several times during his 12 years as leader of the Roman Catholic Church and has suffered a number of health issues throughout his life, including having part of one of his lungs removed at age 21.
