Input: JOHANNESBURG — Former President Nelson Mandela, who has been hospitalized since Saturday, has had a recurrence of a lung infection and is responding to treatment, the office of South Africa’s current president, Jacob Zuma, announced Tuesday. 
  
 It was the first indication of Mr. Mandela’s medical condition since he was flown to Pretoria and taken to a hospital for unspecified tests over the weekend. 
  
 It is his second hospitalization this year; in February he was checked into a hospital for tests to address a chronic stomach complaint, the government said at the time. 
  
 He was released after minor diagnostic surgery, officials said. 
  
 Mr. Mandela, who is 94 and increasingly frail, was “receiving appropriate treatment and he is responding to the treatment,” according to Mr. Zuma’s office. 
  
 The current stay in the hospital is the longest in recent memory, raising fears that Mr. Mandela’s condition is grave. 
  
 Government officials have been upbeat about his prognosis while offering few details about his condition. Given his age, any infection is by its nature serious, medical experts say.

 “I’m not sure we should press the panic button every single time a man of his age has the sniffles,” Mark Sonderup, vice chairman at the South African Medical Association, told The Mail and Guardian, a weekly newspaper, this week. 
  
 “But unfortunately,” he added, “we have to accept that simple health matters for a person of that age can turn very serious, very quickly.” 
  
 Mr. Mandela, South Africa’s first black president, has had respiratory ailments for years, in part owing to the 27 years he spent in prison, most of it on Robben Island, working in a bleak quarry. 
  
 He was given a diagnosis of tuberculosis in 1988 and had fluid drained from his lungs. 
  
 Mr. Mandela retired from public life some years ago, and he was last seen publicly at the celebrations for the World Cup soccer tournament, which South Africa hosted in 2010, although he receives frequent visits from old friends and visiting dignitaries. 
  
 In January 2011, he was hospitalized for an acute respiratory infection, and the news of that illness set off a panic about his health. 
  
 When Secretary of State Hillary Rodham Clinton visited South Africa in August, she stopped by Mr. Mandela’s home in the rural village of Qunu to see him. In a photograph of the two of them, Mr. Mandela beamed his trademark grin, but looked frail seated in an armchair and dressed in a gray cardigan. 
  
 Mr. Mandela led the African National Congress to a resounding victory in the first fully democratic elections in South Africa’s history in 1994, after negotiating a peaceful transition from white rule. Despite harsh treatments at the hands of the apartheid government, Mr. Mandela advocated forgiveness and reconciliation, making him an icon of peacemaking the world over. 
  
 After a single term as president, Mr. Mandela retired from politics in 1999. ||||| Frail Nelson Mandela's 'sparkle fading': wife 
  
 (AFP) – Dec 11, 2012 
  
 JOHANNESBURG — Ailing anti-apartheid icon Nelson Mandela was Tuesday spending a fourth day in hospital for more tests, as his wife said his trademark "sparkle" was waning. 
  
 Looking calm in an interview with a local television network, Graca Machel did not give details about Mandela's health status, just saying it was painful to see the nonagenarian "aging". 
  
 "I mean, this spirit and this sparkle, you see that somehow it's fading," she told ENews Central Africa (ENCA) on Monday in her first interview since Mandela was hospitalised at the weekend. 
  
 South African government officials have said the former president is comfortable and does not face immediate danger, but they refuse to speculate on when he is likely to be discharged from a Pretoria military hospital. 
  
 Mandela, 94, was at the weekend admitted to hospital for tests that authorities say are expected of people of his age. 
  
 "To see him aging, it's something also which pains you. . . . You understand and you know it has to happen," said Graca. 
  
 Mandela's grand-daughter 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. 
  
 Defence Minister Nosiviwe Mapisa-Nqakula visited 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.

Output:
The first specifics of Nelson Mandela's condition are trickling out following the former president's weekend hospitalization, and they're both encouraging and heart-tugging. The New York Times reports that his condition has been revealed as a recurring lung infection, and he is reportedly "responding to the treatment." But wife Graca Machel spoke yesterday of the difficulty of seeing him age, reports the AFP, telling a news station, "It's something also which pains you. ... I mean, this spirit and this sparkle, you see that somehow it's fading." The 94-year-old was also hospitalized for a respiratory infection in January 2011; he was hospitalized earlier this year with stomach pains.
