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.

VATICAN CITY (RNS) – On Pope Francis’ fifth day in a Rome hospital, doctors repeated their assessment that his condition was “complex” after a CT scan of his chest revealed the onset of pneumonia in both lungs.

Pope Francis has been in and out of the hospital several times over the past few years, previously undergoing abdominal surgery and receiving treatment for bronchitis, a hernia, and more.
