Nelson Mandela remains in hospital today sparking fears about his health amongst South Africans.

The 92-year-old former South African president, who is much loved by the public, was suddenly admitted to hospital in Johannesburg yesterday fuelling speculation in the media and the Twittersphere about his health.

The Nelson Mandela Foundation said yesterday that Mandela was in Milpark Hospital in for “routine tests” and that his health was not in any immediate danger.

The South African government were quick to allay fears with an ANC spokesman, Jackson Mthembu, said not in danger.

“He is a 92-year-old and will have ailments associated with his age and the fact that he stayed the night should not suggest the worst,” she said.

President Jacob Zuma was also quick to dampen speculation.

“President Mandela is comfortable and is well looked after by a good team of medical specialists”.

Mandela’s ex-wife Winnie Madikizela-Mandela visited him in hospital today. The two separated in 1992 and have two daughters together.

Children at a school next door to the hospital put up messages of support including, “We hope you’ll get well soon” and “Madiba, we love you”.
