The medical team said Mandela, 94, has made steady progress and he is still improving.
A news release from President Jacob Zuma said that Mandela underwent a surgery to remove gallstones last month and was also suffering from a recurring lung infection.
The release states that Mandela is receiving care at his home after being hospitalized for two weeks.
He was discharged from a Pretoria hospital Dec. 26 after undergoing surgery Dec. 15.
The positive news comes after his granddaughter said hurtful rumors were being spread about Mandela nearing death.
