The Vatican said Pope Francis’ respiratory infection also involves asthmatic bronchitis, which requires cortisone antibiotic treatment.

Pope Francis, who has been hospitalized since last week, was found to have pneumonia in both lungs following a CT scan on Tuesday, the Vatican said, with tests continuing to indicate “a complex picture” for one of the oldest popes in the church’s history.

Pope Francis has the onset of double pneumonia, the Vatican said on Tuesday, complicating treatment for the 88-year pontiff and indicating a further deterioration in his fragile health. Francis has been suffering from a respiratory infection for more than a week and was admitted to Rome's Gemelli Hospital on February 14.
