Pope Francis, 88, read the newspapers and had breakfast on Sunday after a second night sleeping well at the hospital where he is being treated for a respiratory tract infection, the Vatican said.

Vatican spokesperson Matteo Bruni said he expected to provide a further update later in the day. He noted that substantially new detailed medical information may not be forthcoming given it's a Sunday.

The Argentine Pope, a known workaholic who keeps up a gruelling pace despite his many ailments, was admitted to Rome's Gemelli hospital on Friday after a week-long bout of bronchitis worsened. It was his fourth hospitalization since his 2013 election and raised questions about his increasingly precarious health.

Doctors confirmed a respiratory tract infection and prescribed "absolute rest" alongside unspecified drug therapies. Francis skipped his traditional Sunday noon blessing, declining to even come to his hospital window to wave to a small crowd below that had gathered in hopes of cheering him on.

The Pontifex social media account, which is not written by the Pope himself, thanked people for their prayers on Sunday.

"Thank you for the affection, prayer and closeness with which you are accompanying me in these days," the post read.

History of lung ailments

Francis had part of one lung removed after a lung infection when he was a young man and is prone to respiratory infections. In 2023, he spent three days at Gemelli to be treated for what he later revealed was an acute case of pneumonia.

Despite his Feb. 6 bronchitis diagnosis, Francis had kept up a frenetic pace of late, packing his days with private and public audiences while taking on the added obligations of steering the Catholic Church through its Holy Year.

The Vatican has cancelled his events through Monday at least. On Sunday, a Holy Year Mass he was supposed to preside over for visiting artists was instead celebrated by the Vatican culture minister.

The Vatican hasn't specified what type of respiratory tract infection the Pope has. Sometimes bronchitis can lead to pneumonia, a deeper and far more serious infection of the lungs' air sacs.

Treatment varies by severity but can include providing oxygen through a nasal tube or mask, intravenous fluids — and treatment of the underlying cause of the infection.
