Friday marks three weeks since Pope Francis was hospitalized for bronchitis, which then led to double pneumonia.

The 88-year-old pope has remained stable, with no fever and good oxygen levels in his blood for several days, doctors said.

Pope Francis was hospitalized on Feb. 14 after suffering a bout of bronchitis for weeks and after increasingly finding it hard to speak publicly.

With Pope Francis entering his fourth week in hospital, those working in the Apostolic Palace are grappling with the continuing uncertainty over the pope’s health. The same is true for everyone in the Vatican.

The 88-year-old pontiff has been hospitalized since Feb. 14 after a bout of bronchitis worsened and turned into a complex pneumonia in both lungs.

Pope Francis is continuing his recovery from double pneumonia as the Vatican’s Holy Year is proceeding without him.

Pope Francis is showing a "good response" to his treatment in hospital for double pneumonia and his overall condition is gradually improving, the Vatican said on Saturday. Francis, 88, has been in Rome's Gemelli hospital for more than three weeks with a severe respiratory infection that has required continuously evolving treatment.

VATICAN CITY - Pope Francis is showing a "good response" to his hospital treatment for double pneumonia and his overall condition is gradually improving, the Vatican said on Saturday. Francis, 88, has been in Rome's Gemelli hospital for more than three weeks with a severe respiratory infection that has required continuously evolving treatment.

"The night was quiet, the pope was resting," the Holy See, the Vatican's press office, said in a brief statement on Sunday morning.
