Answer 1

CDC.it consists of an triangle of epidemiology which contains environment agent and host the triangle is based on communicable diseases model and is useful in showing the interactions and interdependence of agent host and environment the modifiable advanced model of triangle of epidemiology consists of causative factors and group or population and their characteristics and environment behaviour culture physiological factors ecological elements.there are level of prevention for the disease first is the primordial level primordial level means underlying economic social and environmental condition leading to causation of disease the main aim is to establish and maintain condition that minimise hazard to health the action is that measure that inhibit the emergence of environmental economic social and behavioral condition the main target of primordial prevention is total population of selected group and achieved through public health policy and health promotion.

primary level of prevention is specific causal factor of disease the main aim is to reduce the incidence of disease the action is protection of health by personal community effort such as enhancing nutritional status providing immunization and eliminating environmental risk the total population selected group and individual at higher risk achieved through public health program.secondary level of prevention early stage of disease it reduce the prevalence of disease by decreasing its duration its main aim is to decrease the disability which may come and the targets are individual with the stablished diseases tertiary level of prevention is the late stage of diseases it reduce the number of impact and complication the main aim is to decrease the long-term disease and disability and main a target are patient.

there are modes of intervention by which we can decrease the diseases in population first by health promotion second by specific protection third by early detection and treatment fourth by disability limitation fifth by rehabilitation.we can promote health by health education environmental modification and nutritional interventions and lifestyle and behavioral changes the specific protection include immunization and use of specific tools nutrients chemoprophylaxis and protection against environmental and occupational hazards the early diagnosis include the early diagnosis of the diseases and biochemical morphology and disability limitation include impairment, disability, handicap.

rehabilitation has been defined as the combined and co-ordinate use of medical social educational and vocational measure for a training and retraining the individual to the highest possible level of functional ability.
