Pope Francis’ condition poses no immediate threat to his life though he remains at risk after a week in the hospital for treatment of pneumonia, doctors said.

Following Pope Francis’ diagnosis of bilateral pneumonia, respiratory doctors are speaking about the condition. The Vatican announced the Catholic leader’s diagnosis this week.

The Vatican said Pope Francis has the "onset of bilateral pneumonia," and that tests, a chest X-ray and the pope's clinical condition present a "complex picture."

Pope Francis is “alert and responsive” as he remains hospitalized with pneumonia, Italian Prime Minister Giorgia Meloni said after visiting the pontiff.

Pope Francis, the 88-year-old head of the 1.4-billion-member Roman Catholic Church, is in hospital being treated for double pneumonia following a respiratory infection.

On Wednesday, the Vatican said Pope Francis “had a tranquil night, woke up and had breakfast,” saying he was in good spirits. Here’s a look at what a pneumonia diagnosis can mean and potential treatments doctors might be trying: Pope Francis was admitted to Rome’s Gemilli hospital in “fair” condition on Friday after his bronchitis worsened.

Pope Francis, who remains hospitalized, has bilateral pneumonia, the Vatican said on Tuesday. The term simply means pneumonia in both lungs, said Dr. James Musser, director of the center for infectious diseases at the Houston Methodist Research Institute.

Pope Francis has pneumonia in both lungs  and remains in the hospital in Rome after a respiratory tract infection. The pontiff has contended with repeated health issues in recent years, including from influenza and respiratory infections.

Pope Francis’s health conditions are worsening as the pontiff remains in hospital indefinitely being treated for pneumonia in what the Vatican described as a “complex picture.”

What does Pope Francis having "double pneumonia" mean? What should you look for in the elderly? How can you avoid getting pneumonia?

Pope Francis was found to have pneumonia in both his lungs Tuesday and his condition remains "complex," the Vatican said in a health update on the 88-year-old pontiff who was hospitalized last week. The big picture: The pope was admitted to Rome's Agostino Gemelli Hospital on Friday with bronchitis symptoms and his treatment was changed after doctors found he had a polymicrobial infection of the respiratory tract.
