Through activities ranging from basic research, to frontline efforts such as vaccination programs, promotion of healthy lifestyles and environments, disease control, and leadership on health policy formation, Public Health issues and outcomes touch the lives of people throughout the world. Public Health is an interdisciplinary field drawing on the natural and social sciences as well as the humanities. One of the most important themes in Public Health is the disparities in health observed in different groups, for example related to economic resources and race/ethnicity, which is a focus in this curriculum.
