Pope Francis, who was taken to hospital on Friday for treatment of bronchitis, is suffering from a respiratory infection but is in a stable condition, the Vatican said, APA reports citing Reuters.
"The Holy Father ... has undergone specialist examinations and has started hospital drug therapy," said a statement, issued about eight hours after the pope was taken to Rome's Gemelli hospital.
"The initial tests showed a respiratory tract infection," it said. "His clinical condition is fair; he has a slight fever."
Vatican spokesman Matteo Bruni said the pope was serene and in good spirits, and had read a few newspapers.
Francis, 88, has been suffering from bronchitis for more than a week.
