Johannesburg — Former President Nelson Mandela remained in hospital on Sunday, the Presidency said.
Spokesman Mac Maharaj said there was "no new update" on his condition on Sunday.
On Saturday, Maharaj said Mandela was responding to treatment as he continued his stay in hospital which has now been for over a fortnight.
Mandela, 94, was diagnosed with a lung infection and also underwent gallstone surgery.
He was originally flown to hospital in Pretoria from his Eastern Cape home at Qunu on December 8.
On Saturday, President Jacob Zuma visited Mandela in hospital and asked South Africans to pray for the global icon.
"We urge South Africans to continue praying for our beloved Madiba during this period. Our hearts are with the whole family and relatives."
Mandela has a history of lung problems having suffered from tuberculosis towards the end of the 27 years he spent in prison.
His current stay in hospital is his longest since he was freed over two decades ago.
