Archbishop Desmond Tutu has wrestled with health problems for years

He received the Nobel Peace Prize in 1984 for his efforts to end apartheid in South Africa

(CNN) —  

Nobel Peace Prize winner Archbishop Desmond Tutu is being treated in a hospital for a persistent infection, his representatives said.

The 83-year-old, who has wrestled with health problems for years, was admitted Tuesday to a hospital in Cape Town, South Africa, and is expected to remain there through Wednesday night.

Tutu’s daughter, Canon Mpho Tutu, didn’t elaborate on the kind of inflammation but said it was unrelated to the infection that sent him to the hospital last month.

The daughter said her father “wished to thank everyone who had sent love and prayers over the past 24 hours, telephonically, electronically and through social and mass media channels,” read a statement issued Wednesday through his representatives.

“He is 83, not 38,” his daughter said. “So bouncing back from an illness is not quite as easy as it once was.”

“My mother is worried,” she added. “They have been together for 60 years.”

Tutu, who received the Nobel Peace Prize in 1984 for his efforts to end apartheid in his native South Africa, has remained active well into his 80s with the Desmond Tutu Peace Foundation and other organizations.

He previously underwent hospital tests for a persistent infection in 2013.

Last year, he canceled travel plans because of a long-running battle with prostate cancer.
