Global Health, Complexity, and Self-Awareness The work of global health is complex. 1 It is as much about the study and application of anthropology, economics, political science, and psychology as about physiology and pharmaceuticals. 2 It is as much about pathologies of power and good governance as about emerging infectious diseases. 3,4,5 It is as much about relationships as about medical science. 6 Opportunities for US-based health professions students and trainees to examine these complexities often come in the form of short-term experiences in global health (STEGHs)-service-learning immersions in international and domestic settings of need (see Figure 1).
