Commentary: The social pathology of the HIV/AIDS pandemic

Abstract
Working in a remote region of South Africa more than 50 years ago, Sidney Kark practised what many today would think of as social epidemiology. His approach was refined and disseminated across the globe by his students in subsequent decades, thereby influencing the evolution of the modern discipline. Equally important, his commitment to the health of indigenous African populations makes him one of the earliest role models in global public health.
