Presidential spokesperson Mac Maharaj says former President Nelson Mandela is responding to treatment he's receiving at the One Military Hospital in Pretoria.
Mandela is being treated for a recurring lung infection. The presidency says doctors have concluded the tests they have been conducting on Mandela.
Maharaj has re-iterated that Mandela is receiving the appropriate treatment and is responding to it. He says there is no need for panic at this stage.
"Around Madiba and his age there's always need for concern when matters on his health arise. But there's no need for panic at this stage in relation with this infection. You must remember that he was diagnosed with having TB when he was in prison. So there's a history of weak lungs, susceptibility to infection. So there's a history of successful treatment."
President Jacob Zuma has also thanked members of the public for their continuous support for Madiba and his family.
There is no need for panic at this stage.
Meanwhile, rain did not deter news crews camping outside the hospital where Mandela had spent a third night.
This morning, vehicles of different media houses, local and international, lined the street adjacent to the hospital, at the Thaba Tshwane Military Base.
Journalists had erected large umbrellas and plastic sheets to shield cameras fixed on tripods. Military police stopped and inspected cars at the hospital's main entrance, before allowing them onto the premises.
Earlier, vehicles belonging to news crews, including an outside broadcast vehicle, were turned back at the entrance. Several journalists milled outside, metres from the security checkpoint.
