Yeltsin Improving, Kremlin Says

President Boris N. Yeltsin received hospital treatment for the flu, and his temperature was returning to normal, the Kremlin said. Spokesman Dmitri D. Yakushkin did not provide details on the treatment or say when the president, who was hospitalized Saturday, might be released, according to the Interfax news agency. Yeltsin met with his chief of staff, Alexander S. Voloshin, at the hospital, Yakushkin said. The president did not give any additional powers to Prime Minister Vladimir V. Putin--a sign that the illness was not serious, Interfax said.
