Public health

is the organised response by society to protect and promote health, and to prevent illness, injury and disability. The starting point for identifying public health issues, problems and priorities, and for designing and implementing interventions, is the population as a whole, or population sub-groups.


Definition taken from 'A Memorandum of Understanding; to establish a National Public Health Partnership for Australia', 1997, and a modification of that proposed in Last, JM. Public Health and Human Ecology. Connecticut. Appleton and Lange. 1987.
Although priorities may change as technology advances and social values change, the public health goals of reducing the level of disease, the risk of premature death and disease-produced discomfort and disability in the population remain the same. Public health hazards may be environmental, nutritional, related to alcohol or other drugs, food safety, communicable and non-communicable diseases, and other hazards causing injury.

The scope of public health activities and processes can be grouped into three key areas.

Public health intelligence is involved with gathering and analysing information about the determinants of health, the causes of ill health and the patterns and trends of health and ill health in the population.

Public health intervention refers to developing policy, setting priorities for actions, developing plans, coordinating services, strategies and interventions aimed at prevention, protection and promotion of the health of the community, where promotion is the action taken to solve public health problems.

Public health infrastructure refers to the administrative, legislative and informational systems developed for making priorities, for developing policy, for funding, for monitoring and surveillance, for research and evaluation, for program delivery, and includes the workforce required to accomplish these tasks.
