Cuban leader Fidel Castro is reported to be in very serious condition after three failed operations and complications from an intestinal infection.
The Spanish newspaper El Pais reported on its Web site Monday that Mr. Castro suffers from a serious infection that has worsened to peritonitis.
The condition is a painful and potentially fatal inflammation of the lining of the abdominal cavity often caused by infection in an organ.
A White House spokesman Tuesday called the report "nothing new."
A Spanish surgeon who examined Mr. Castro last month, Jose Luis Garcia Sabrido, told reporters in December the Cuban leader was slowly recovering and wanted to return to work. The surgeon denied reports the Cuban leader had cancer.
But El Pais cites sources at the surgeon's hospital, Gregorio Maranon Hospital, as saying the infections have left Mr. Castro with a very grave prognosis.
Tuesday, Dr. Garcia Sabrido's secretary told Reuters news agency nothing has changed since the surgeon spoke in December.
The 80-year-old Cuban leader underwent an operation at the end of July and has not appeared in public since. He temporarily ceded power to his brother, Defense Minister Raul Castro.
The newspaper report has not been confirmed. The Cuban government treats Mr. Castro's health as a state secret.
