Pope Francis is battling a complex lung infection, including double pneumonia, caused by viral, bacterial, and fungal pathogens. He is receiving a combination of cortisone, antibiotics, and supplemental oxygen as needed.

The main health risks include the potential development of sepsis, a serious blood infection that can lead to organ failure, and complications from his chronic lung conditions and age.

Yes, there has been speculation, but the Vatican has addressed these rumors, emphasizing that the focus is on the pope's recovery. Pope Francis has previously stated that he would consider resignation if his health prevented him from performing his duties.

Pope Francis remains alert and in good spirits, although he is experiencing more pain. He continues to work from his hospital room and has expressed gratitude for the support he has received.
