The wife of Nelson Mandela says he is better than he was a week ago.
Graca Machel said on Saturday he is showing signs of improvement and she is less anxious about him than she was a week ago.
"He continues to respond positively to treatment. I would say that today I am less anxious than I was a week ago," she told eNCA news.
The former president has been in hospital in Pretoria since 8 June for a recurring lung infection that has led to four hospital stays in the past six months.
He is due to turn 95 on Thursday, 18 July.
After visiting Mr Mandela late on Thursday, President Jacob Zuma said he was "responding to treatment."
"He remains as much of a fighter now as he was 50 years ago," Mr Zuma said.
