A South African foundation says retired archbishop Desmond Tutu has been admitted to a Cape Town hospital for a persistent infection.

The foundation, which is named after 83-year-old Tutu and his wife Leah, on Tuesday quoted their daughter Mpho as saying the family hopes the Nobel Peace Prize laureate will be able to return home in a "day or two."

Desmond Tutu has been treated for prostate cancer for many years. He announced his retirement from public life in 2011 but has still traveled widely and made public appearances.

Tutu, who was awarded the Nobel peace prize in 1984 for campaigning against apartheid, renewed his wedding vows with Leah earlier this month after 60 years of marriage.
