Pope Francis, 88, remains hospitalized at Rome's Gemelli Hospital as his medical team adjusts his treatment plan to tackle a 'complex clinical situation,' as stated by the Vatican on Monday.

The pope has been battling a respiratory tract infection for more than a week, having been admitted to the facility last Friday.

According to the Vatican's announcement, test results reveal a polymicrobial infection of the respiratory tract, leading to a modification of the pope's treatment.

The described 'complex' condition requires an extended hospital stay, although the Vatican confirmed that Pope Francis is stable and displays no signs of fever.

Even while hospitalized, the pope has been reaching out to communities, maintaining communication with Gaza's sole Catholic parish.

Father Gabriel Romanelli, a local priest, reported that during a video call, Pope Francis shared his feelings about his health, noting that he feels weary but hopeful, stating, 'A few days (in the hospital) and I'll be back.' Romanelli described the pontiff as 'not an easy patient for doctors,' highlighting his active interactions.

On Monday, Pope Francis continued to conduct work and review paperwork while staying in the hospital.

Vatican spokesperson Matteo Bruni did not specify whether the root cause of the infection was bacterial or viral.

Bacterial infections are generally treated with antibiotics, while viral infections require supportive care, as they do not respond to antibiotics.

A polymicrobial infection involves various microorganisms and can be caused by bacterial, viral, or fungal agents.

Rev. Dr. Andrea Vicini, a Jesuit priest and medical doctor, clarified that polymicrobial is a general term and does not specify the exact type of infection affecting the pope.

He noted that recent reports of the pope having breakfast indicate that his health permits digestion and that he does not require respiratory support.

Pope Francis, who has been pontiff since 2013, has encountered several health challenges in recent years, including periods of influenza and respiratory issues.

In his earlier years, he developed pleurisy and underwent surgery to remove part of a lung.

His current hospitalization has resulted in the cancellation of his weekly audience in St. Peter's Square, as well as a special Mass for artists celebrating the Catholic Church's Jubilee Year.

Visitors to the Vatican have expressed their hopes for the pope's swift recovery.

Rev. Tyler Carter, a Catholic priest from the United States, remarked, 'We certainly wish for him to recover very soon. He is our father and our shepherd, and we desire his enduring health and blessings.'
