Zuma visits Mandela Houghton home

Presidency confirms that South Africa president Jacob Zuma visited Nelson Mandela this morning at his Houghton home

The visit comes amidst reports that the world icon is still is still in a critical condition and he's unable to speak, but usus facial expressions to communicate 

Mandela's  former wife  , Winnie Madikizela-Mandela, told to the local media that the 95-year-old remained "quite ill", but she dismissed speculation that he was on a life support machine.

Nelson Mandela is no longer talking "because of all the tubes that are in his mouth to clear [fluid from] the lungs", Ms. Madikizela-Mandela told South Africa's Sunday Independent newspaper.

"He can't actually articulate anything. He communicates with the face, you see. But the doctors have told us they hope to recover his voice.

 "I have heard this nonsense that he is on life support - he is not."It is difficult for him. He remains very sensitive to any germs, so he has to be kept literally sterile. The bedroom there is like an ICU [intensive care unit] ward," she told.

In September Mandela returned home after nearly three months in hospital with a recurring lung infection. 

The government has said his condition is critical and sometimes unstable. The South African presidency has been keen to reassure not just the Mandela family but the nation that he is no more vulnerable at home than in hospital. It has called for Mr. Mandela's privacy and dignity to be respected.

Nelson Mandela has been receiving intensive care at his home in a suburb of Johannesburg, which has been specially adapted for his care. 

The Nobel Peace Prize laureate is revered around the world for leading the fight against white minority rule and preaching reconciliation with the white community despite being imprisoned for 27 years.
