Camp Sizanani in South Africa was founded nine years ago by Phil Lilienthal — who had served in Africa with the Peace Corps and had worked in camps in the U.S.
Camp Sizanani provides a week-long program that teaches kids how to avoid contracting AIDS and HIV. For campers that are already infected, it teaches them about how to stay healthy.
A recent evaluation by the University of Georgia found the camp is having a positive impact on the lives of campers.
