Pope Francis has shown further slight improvement as he battles double pneumonia, but doctors said Wednesday his prognosis is still guarded.

Pope Francis was a frequent visitor to Rome long before he became pope. Now his favorite shops and artisans are pulling for him as he battles double pneumonia.

Pope Francis was sitting upright and receiving therapy for double pneumonia on Wednesday, the Vatican said. The Vatican said that it hoped to have information later in the day about the results of a CT scan taken on Tuesday evening to check on the status of the complex lung infection that has kept him hospitalised since February 14.
