Defining Public Health 2. From Public Health to Global Health 3. Tuberculosis (TB) as an example of a global health problem Acheson, 1988 Public health is the art and science of preventing disease, prolonging life and promoting health through the organized efforts of society Last, 2011 One of the efforts to protect, promote and restore the people’s health.

It moves beyond a focus on individual behaviour towards a wide range of social and environmental interventions. Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems Last, 2001 2. From Public Health to Global Health Global Health Global health is an area for study, research, and practice that places a priority on improving health and achieving equity in health for all people worldwide. Global health emphasizes transnational health issues, determinants, and solutions; involves many disciplines within and beyond the health sciences and promotes interdisciplinary collaboration; and is a synthesis of population based prevention with individual-level clinical care. • Global health deals with structural determinants of health. Those factors that make people are less priviledged, those factors that create terms such as “low income” and “middle income countries” • Global health deals with those diseases that disproportionally affect the poorest sectors of societies • Global health deals with strengthening fragile health systems so health provision is equitable. • Global health deals with universal health coverage • Global health does not necessarily deal with health problems that affect many people or many countries. WHO SHAPES GLOBAL HEALTH ? 3.
