President Jacob Zuma's office is yet to issue updates on the revered 94-year-old statesman's health condition since an official statement yesterday.
"Doctors advise that due to the lung infection former President Mandela had developed a pleural effusion which was tapped. This has resulted in him now being able to breathe without difficulty. He continues to respond to treatment and is comfortable," Presidential spokesperson Mac Maharaj said in the statement yesterday.
Earlier this month, Mandela spent a night at a Pretoria hospital where he underwent a successful medical examination.
Three months ago, he was admitted for 18 days for treatment of the lung infection and surgery to extract gallstones. It was his longest stint in hospital since his release from prison in 1990.
Mandela had a long history of lung problems, dating back to the time when he was a political prisoner on Robben Island during apartheid. While in jail he contracted tuberculosis.
