South African Archbishop Desmond Tutu was re-admitted to a hospital in Cape Town complaining about discomfort on Tuesday, said his daughter, Mpho Tutu.
Tutu was hospitalized on July 20 to receive treatment for a persistent infection and released the next day.
“His doctors considered it prudent for him to return to hospital for observation,” she said in an e-mailed statement. Tutu will stay under supervised bed rest until at least the weekend as doctors determine the next steps, she said.
Tutu, 83, won the 1984 Nobel Peace Prize for his opposition to white-minority rule in South Africa, which ended a decade later. While retired, he remains an outspoken champion on issues ranging from human rights to justice and equality.
Tutu has previously fought prostate cancer. His current sickness is unrelated to cancer and he has low levels of PSA, a protein associated with prostate cancer at high levels, said his daughter.
