(CNN) -- Former President George W. Bush and his wife, Laura, are in Africa this week, where they renovated a cancer screening clinic in Zambia and commemorated the victims of the 1998 U.S. Embassy bombing in Tanzania. The clinic, which is designed help women fight cervical cancer, builds on the former president's work fighting AIDS on the continent. While he was in office, Bush set up a plan that dramatically reduced the number of AIDS deaths in Africa. "I'm really proud of the American people for their generosity," he told CNN in an exclusive interview. "I wish Americans knew how many lives were saved. Someday, they will."
