What are the factors complicating Pope Francis's pneumonia treatment?

Pope Francis's pneumonia treatment is complicated by several factors. The pontiff has a polymicrobial infection affecting both lungs, which makes treatment more complex than a simple bronchitis case. The Vatican confirms that a CT scan revealed this more serious condition requiring specialized care. Adding to the complications is the Pope's advanced age of 88 years and his medical history. As a young man, he had part of a lung removed, which creates additional vulnerability in his respiratory system. Despite these challenges, reports indicate he remains in good spirits and continues with some routine activities while receiving treatment.
