Nelson Mandela suffering from lung infection and 'sparkle fading' "Doctors have concluded the tests, and these have revealed a recurrence of a previous lung infection, for which Madiba is receiving appropriate treatment and he is responding to the treatment," said a statement from President Jacob Zuma's office. Mr Mandela, 94, was at the weekend admitted to hospital for tests that authorities say are expected of people of his age. To see him ageing, it's something also which pains you ... You understand and you know it has to happen," said Graca. Mr Mandela's granddaughter Ndileka told the same TV network that he has taken to accept his condition. I think he takes it in his strides, he has come to accept that it's part of growing old, and it's part of humanity as such. At some point you will dependent on someone else, he has come to embrace it," she said. Nosiviwe Mapisa-Nqakula, the defence minister, visited Mr Mandela on Monday and said the revered statesman was "doing very, very well." The presidency said it was too early to give an update as they have to hear first from the doctors.
