Pope Francis has shown the onset of double pneumonia, further complicating treatment for the 88-year pontiff, the Vatican said on Tuesday. "The laboratory tests, chest X-ray, and clinical conditions of the Holy Father continue to present a complex picture," said a statement. "(A) chest CAT scan which the Holy Father received this afternoon ... showed the onset of bilaterial pneumonia that requires further pharmacological therapy," it added.

Bilaterial pneumonia is an infection that affects both lungs, and can make breathing difficult. Francis has been suffering from a respiratory infection for more than a week and was admitted to Rome's Gemelli hospital on February 14. He is especially prone to lung infections because as a young adult he developed pleurisy and had part of one lung removed. A Vatican official speaking on background earlier in the day, said the pontiff had not been put on a ventilator and was breathing on his own. Ahead of the latest statement, the Vatican announced that all public events on the pope's calendar had been cancelled through Sunday. The Vatican has said Francis will stay in hospital for as long as necessary. It has not specified whether the pope is suffering from a bacterial or viral infection.
