What happened to Pope Francis's health condition after he was admitted to the hospital?

The 88-year-old Pope Francis was initially admitted to Rome's hospital last Friday for bronchitis. However, his condition evolved into something more serious, as a CT scan later revealed the development of bilateral pneumonia, which affects both lungs simultaneously. In response to this concerning development, the Vatican announced that his treatment plan was being modified to address the pneumonia. Despite these health challenges, the Vatican has indicated that Pope Francis remains in good spirits, though he has had to cancel several public engagements including a planned Mass.
