What’s the definition of PUBLIC HEALTH?
The definition of public health that has perhaps best stood the test of time is that suggested by Winslow almost 90 years ago
   Public health is the science and art of disease prevention, prolonging life, and promoting health and well-being through organized community effort for the sanitation of the environment, the control of communicable infections, the organization of medical and nursing services for the early diagnosis and prevention of disease, the education of the individual in personal health and the development of the social machinery to assure everyone a standard of living adequate for the maintenance or improvement of health.(1920)

In the Dictionary of epidemiology (2001), Last defined public health as “one of the efforts to protect, promote and restore the people’s health. It is the combination of sciences, skills and beliefs that is directed to the maintenance and improvement of the health of all the people through collective or social actions”.

What’s the definition of INTERNATIONAL HEALTH?

“the application of the principles of public health to problems and challenges that affect low and middle-income countries and to the complex array of global and local forces that influence them”

What’s the definition of 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.
