CARACAS, Venezuela — A severe new respiratory infection has hit cancer-stricken President Hugo Chavez and his condition is "very delicate," Venezuela's government says. A brief statement read on national television by Communications Minister Ernesto Villegas late Monday carried the sobering news about the charismatic 58-year-old socialist leader's deteriorating health. Villegas said Chavez is suffering from "a new, severe infection." The state news agency identified it as respiratory. Chavez has been undergoing "chemotherapy of strong impact," Villegas added without providing further details. Chavez has neither been seen nor heard from, except for photos released in mid-February, since submitting to a fourth round of surgery in Cuba on Dec. 11 for an unspecified cancer in the pelvic area.Villegas took the opportunity to lash out at "the corrupt Venezuelan right" for what he called a psychological war seeking "scenarios of violence as a pretext for foreign intervention." He called on Chavez's supporters, who include thousands of well-armed militiamen, to be "on a war footing." Upon Chavez's death, the opposition would contest the government's candidate in a snap election that it argues should have been called after Chavez was unable to be sworn in on Jan. 10 as the constitution stipulates. Indeed, the campaigning has already begun, although undeclared. Vice President Nicolas Maduro, who Chavez has said should succeed him, has frequently commandeered all broadcast channels, Chavez-style, to tout the "revolution" and vilify the opposition. One of Chavez's three daughters, Maria Gabriela, expressed thanks to well-wishers via her Twitter account. "We will prevail!" she wrote. — AP
