International Public Health aims to Improve Public Health at the International Level

Public health as part of medicine deals with threats to the general health of the community based on population health analyses. Many organizations define health and health promotion in different ways. The World Health Organization, the UN body that sets standards and conducts global disease surveillance, defines health as "a state of complete physical, mental and social well-being and not merely freedom from disease or disability." The word "population" in this context can refer to anything from a small group of people to entire continents. The goal of health care is to prevent rather than treat disease, through surveillance of disease cases and promotion of healthy living. In addition to these activities, the treatment of a disease often has a key importance for preventing the same disease in others, as happens in outbreaks of infectious diseases. Vaccination and distribution of condoms are some examples of health measures.
