Pope Francis was admitted to Rome’s Gemelli Hospital on Friday to undergo testing and treatment for bronchitis, the Vatican said. The 88-year-old Pope was hospitalized in the late morning on Feb. 14, following meetings with a number of people, including Prime Minister Robert Fico of Slovakia.

Pope Francis remains hospitalized at Rome’s Gemelli hospital for the seventh day as concerns over his health intensify. Initially admitted for bronchitis, his condition worsened into pneumonia, sparking widespread prayers from the faithful.

Pope Francis, who is receiving treatment in hospital for a respiratory tract infection, will not appear in public on Sunday to lead his usual weekly prayer with pilgrims, the Vatican said.
