Holistic Concept: This concept encompasses all the other concepts. The influence of social, economic, political and environment on health has been well identified. It has been described as unified or multidimensional process of achieving well being of a person in the context of environment. This concept corresponds to the view of ancient population that health implies sound mind in a sound body in a sound family and in a sound environment. The holistic approach indicates that all sectors of the society have an influence on health particularly agriculture, animal husbandry, food, industry, education, housing, public works, communication and alike, with emphasis on promotion and protection of health.
“Good public health is basically good health”
Environmental factors and ecological considerations must be built into the total planning process. Prevention of disease through ecological or environmental manipulations or interventions is much cheaper, safer and sustainable rational approach than other means of control. Many diseases like cholera, malaria, typhoid and hookworm infestations can be controlled or eliminated by environmental manipulations.
