The Vatican says Pope John Paul is suffering from a high fever caused by a urinary tract infection. Vatican spokesman Joaquin Navarro-Valls said late Thursday that the 84-year-old pope is being given what he calls the "appropriate antibiotic therapy" by a medical team at the Vatican. The chief doctor at Rome's Gemelli Hospital says there are no immediate plans to admit the pope. Earlier this week, doctors inserted a nasal feeding tube into the pope to boost his strength and help him recover from February's throat surgery to correct breathing problems. The pontiff tried to speak but failed when he appeared at his window overlooking Saint Peter's Square Wednesday. The pope has suffered from severe arthritis and Parkinson's Disease for several years. He has been hospitalized twice in the last two months.
