Approaches to health, health care, and the terminology to describe global health have evolved over the past 70 years since the introduction of the Constitution of the World Health Organization and definition of health in broader terms. The early focus on individual care gradually shifted to community, population, and global approaches, with associated changes in the site of medical care, the personnel who provide it, and the education and training of those personnel. Concomitantly, goals changed from purely curative care to disease prevention and health promotion. Health was better understood to exist within the larger political, social, cultural, and ethical settings.
