He planned to visit Sudan in 2022 but couldn’t because of knee inflammation. He made the journey earlier this year. Vatican spokesman Matteo Bruni said Francis was improving from the flu and inflammation of his respiratory tract that had forced him to cancel his audiences Saturday. “The doctors have asked the pope not to make the trip planned for the coming days to Dubai,” he said. “Pope Francis accepted the doctors’ request with great regret and the trip is therefore canceled.”Francis had part of a lung removed when he was younger and has been prone to respiratory problems. He also has mobility issues from strained knee ligaments that have forced him to use a wheelchair or cane. A giant screen broadcasts Pope Francis coughing during the Angelus noon prayer, from the chapel of the hotel at the Vatican grounds where he lives.
