JOHANNESBURG — Doctors are doing all they can to improve Nelson Mandela's health as the 94-year-old icon spent a fourth day in the hospital for a recurring lung infection, South Africa's president said Tuesday, as two of Mandela's daughters visited their father.
In a possible sign of the seriousness of Mandela's condition, daughter Zenani Mandela — South Africa's ambassador to Argentina — arrived at the hospital to see her father. Former wife Winnie Madikizela-Mandela also visited.
Mandela's doctors briefed President Jacob Zuma on the former president's health late Monday, the president said in a statement.
In an interview, Zuma called Mandela's situation "very serious" but said he has stabilized.
"We need him to be with us and I'm sure that all the messages that have been pouring in to wish him (a) quick and speedy recovery, they're highly welcome," Zuma told broadcaster SABC, adding later: "And we certainly join everyone to say he should recover quickly, and I'm sure, knowing him as I do, he's a good fighter, he will be with us very soon."
White House spokesman Jay Carney said that President Barack Obama, the first lady and everyone at the White House wished Mandela a "speedy recovery."
In a Johannesburg suburb, school children gathered outside his home on Tuesday and sang songs expressing hope the former president would recover.
Mandela, the leader of South Africa's anti-apartheid movement, spent 27 years in prison during white racist rule. He was freed in 1990, and then embarked on peacemaking efforts during the tense transition that saw the demise of the apartheid system and his own election as South Africa's first black president in 1994.
