Vatican spokesman Joaquin Navarro-Valls told The Associated Press that the decision to hospitalize the 84-year-old pontiff was "mainly a precaution."
He pointed out that the pope was not in intensive care but in the same 10th floor suite of rooms where he has been during several previous stays at Rome's Gemelli Polyclinic, about 2 1/2 miles from the Vatican.
The pope has the flu and acute laryngeal tracheitis, Navarro-Valls said, acknowledging the pontiff had a "certain difficulty in breathing."
