JOHANNESBURG, Dec 11 (Reuters) - Former South African President Nelson Mandela, in hospital for tests since Saturday, has suffered a recurrence of a lung infection but is responding to treatment, a government statement said on Tuesday.
"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," the statement said. 'Madiba' is Mandela's clan name.
The 94-year-old former South African president and revered anti-apartheid leader is spending his fourth day in a hospital in the South African capital Pretoria.
Mandela was admitted on Saturday after being flown from his home village of Qunu, which is in a remote, rural part of the Eastern Cape province.
The nation's Surgeon-General was expected to give an update on Mandela's condition later on Tuesday.
