Mixed signals from officials in Venezuela sparked confusion on Monday over the condition of cancer-stricken President Hugo Chavez, under treatment in a Cuban hospital for over a month

Mixed signals from officials in Venezuela sparked confusion on Monday over the condition of cancer-stricken President Hugo Chavez, under treatment in a Cuban hospital for over a month.
  
Chavez is "fighting for his life," former vice president Elias Jaua said. "The situation is complex and delicate, but it is true that Hugo Chavez has fought and is fighting for his life," said Jaua, who was in office from January 2010 until October.
  
Communications Minister Ernesto Villegas, however, said that Chavez, hospitalized in Cuba following his fourth cancer operation last month, was doing better. "Despite his delicate health state since his complex surgery on December 11, his general health has improved in recent days," Villegas said in a statement read on radio and television.
  
The president's previously disclosed severe pulmonary infection was "under control" but he still required treatment for "respiratory failure," he added. Chavez, whose OPEC-member nation controls the world's largest proven oil reserves, has been out of sight since leaving for Cuba for the latest round of treatment in the 18 months since his condition was made public.
  
Uncertainty about his status has fueled speculation about his prospects for a full recovery -- and his political future. The latest, conflicting reports followed a denial from Chavez's brother Adan on Saturday that the 58-year-old was in a coma. He insisted the Venezuelan leader was responding well to treatment and making progress on a daily basis.
