Pope Francis made his first public appearance in over five weeks on Sunday, addressing supporters from a balcony at Rome's Gemelli hospital where he has been undergoing treatment.

The 88-year-old pontiff has been hospitalized since February 14 due to a serious respiratory infection, representing the most significant health challenge of his papacy, which has lasted twelve years.

As he is set to be discharged later today, his medical team has stated that he will need a substantial recovery period.

Doctors noted on Saturday that his full recovery will require "a lot of time," recommending an additional two months of rest at the Vatican to aid his healing process.

The pontiff's health and capacity to fulfill his religious responsibilities have been closely observed, given both his age and recent health issues.
