Eric Roth, PhD, is a Professor in the Department of Anthropology at the University of Victoria. He has conducted anthropological demographic research with pastoral populations in northern Kenya for the past twenty years. In this presentation, Dr. Roth will examine patterns of risk and worry about contracting HIV/AIDS, specifically in the Ariaal community of northern Kenya. His findings indicate that individuals in this community are more concerned about the sexual behavior of others than their own, revealing the potential for combining concepts of worry with risk assessment for effective HIV/AIDS intervention programs in this region.
