CAPE TOWN, Aug. 11 (Xinhua) -- Ailing former President Nelson Mandela's health is improving slowly but steadily, the presidency said on Sunday.
"The medical team also reiterated that although his health was improving steadily, Madiba (Mandela's clan name) still remained in a critical condition," presidential spokesman Mac Maharaj said in a statement.
The presidency, which is responsible for issuing updates on Mandela's health, had been mum on Mandela's condition for more than 10 days. Though the number of well-wishers visiting the Pretoria Mediclinic Heart Hospital where Mandela is receiving treatment has been dwindled, people remain concerned over Mandela's health.
Mandela's daughter Zindzi Mandela said on Friday that her father "is fine" and could manage to sit up in a chair for a few minutes in a day.
Every day Mandela "becomes more alert more responsive," Zindzi said in remarks published by the South African Broadcasting Corporation (SABC).
Sunday was Mandela's 65th day in hospital, his longest hospital stay since December last year.
The 95-year-old anti-apartheid hero was admitted to hospital on June 8 for a recurring lung infection.
