The model of causation implied by Figure 1 illuminates several important principles regarding causes. In contrast, other explanatory models may include mystical, personalistic and naturalistic causes of illness or disease (Anderson, 1983; Tan, 1987; Tompar-Tiu & Sustento-Seneriches, 1995). The basic idea of counterfactual theories of causation is that the meaning of causal claims can be explained in terms of counterfactual conditionals of the form "If A had not occurred, C would not have occurred". The model has similarities to the "web of causation" theory described above, but is more developed in the sense that it simultaneously provides a general model for the conditions necessary to cause (and prevent) disease in a single individual and for the epidemiological study of the causes of disease among groups of individuals. Links between medical science and social science and health inequalities are critical in our understanding of the whole system health. These are the principal: germ theory, epidemiological triangle, multifactorial causation theory, web of causation and divers epidemiological model. zModels are guidelines that provide a framework for considering causation at a practical level .

Key words: Social epidemiology, germ theory, multi-causality, general susceptibility Introduction The foundation of modern W estern medicine is generally described as the biomedical model. - Two models presented below may explain multifactorial causation mechanism ; 1. The utility of the general susceptibility view derives from its capacity to explain those phenomena not adequately dealt with by previous theories. cine matured, its lack of an explicit theory made the model of disease causation less available to mental health theory (41). This web of causation explores multi-ple causative factors, giving each an equal prominence in identifying determinants and relevant interventions. Students will describe the major epidemiology study designs, their strengths and weaknesses and demonstrate understanding of conditions under which each study design is preferred. In this model, disease results . 9. Disease Model. Germ Theory - Koch's Postulates. Multifactorial Causation : - Single causation theory does not explain causation of Non-Communicable diseases where multiple factors are involved in causation of disease viz; CHD and Ca-Lung. STUDY. Noted substance abuse researcher, "William Miller" said in 1993 that the disease model we are now utilizing is inefficient in clarifying or explaining the great amount of problems related to AODA.

Models of Disease Causation, Germ Theory, Epidemiological Triad, Web and Wheel of Disease Causation. Germ theory of causation In 1860 Louis Pasteur demonstrated presence of bacteria in the air In 1873 he proposed the germ theory of disease 1877 Robert Koch demonstrated that Anthrax was caused by a bacteria But germ theory did not explain everything Presence of germs did not always cause disease All diseases were not caused by germs Modern Medicine Disease Causation - Henle-Koch Postulates: (1877) A set of 4 criteria to be met before the relationship between a particular infectious agent and a particular disease is accepted as causal. The monocausal model of disease is the view that every disease has a cause satisfying (i) and (ii). Among the simplest of these is the epidemiologic triad or triangle, the traditional model for infectious disease.

Causation A number of models of disease causation have been proposed. The wheel of causation, an alternative model, according to Harkness and DeMarco (2012), "…de-emphasizes the agent as the sole cause of disease, whereas it emphasizes the interplay of physical, biological, and social environments" (p.94). Copy. . Even though there was a "germ" of truth in miasmatic theory, in that it focused attention on environmental causes of disease and partly explained social disparities in health (poor people being more likely to live near foul odors), the theory began to fall into disfavor as the germ theory gained acceptance. A number of models of disease causation have been proposed. Among the simplest of these is the epidemiologic triad or triangle, the traditional model for infectious disease.

This refers to one to one relationship between the causative agent and disease. 1.The domino theory developed by H. W. Heinrich, a safety engineer and pioneer in the field of industrial accident safety. A kind of event C is the requisite kind of cause for disease D if, and only if: (i) a C-event is a cause of every case of D; (ii) given certain circumstances, a C-event is not a cause of any ¬D event (i.e. Within the epidemiological triad the agent is known as a 'necessary' factor. HEALTH • Concepts of health - 1. Web of causation theory States that disease never depends upon single isolated cause; rather it develops from a chain of causation in which each link itself is a result of complex interaction of . Disease concepts are presented as causal networks that represent the relations among the symptoms, causes, and treatment of a disease.

THEORIES AND MODELS OF DISEASE CAUSATION THEORIES AND MODELS OF DISEASE CAUSATION Before the discovery of micro-organism (bacteria by Louis Pasture in 1822-1895) several theories explaining the cause of disease were put forward time to time. Therefore, we elected to use the wheel of causation as a conceptual model to integrate variables related to smoking and back pain, as constructed from BPS theory (Fig 2). The model of web of causation is an important model that has been used in community health to represent different pathways that point on a genesis of a health problem or a disease, giving rise to defined causative risk factors. Epidemiologic Triangle. The model has similarities to the "web of causation" theory described above, but is more developed in the sense that it simultaneously provides a general model for the conditions necessary to cause (and prevent) disease in a single individual and for the epidemiological study of the causes of disease among groups of individuals. These three models of cause and effect are: • Hill's Criteria for Causation • Rothman's Pie Model • Web of Causation. THE GERM THEORY: According to this theory, there is one single specific cause of every disease. Where they differ is in their respective emphasis on different aspects of social and biological .

Although this particular approach has been responsible for tremendous successes in modern medicine, the tendency of the biomedical model to neglect social, economic and psychological factors has been . It is more suited to chronic diseases where agent is not known.

Useful in the depiction of communicable diseases. A number of models of disease causation have been proposed. Socioenvironmental approach Germ Theory: It states that disease is caused by transmissible agents only and the medical practice consists of identifying and neutralizing these agents. COVID- 19. All seek to elucidate principles capable of explaining social inequalities in health, and all represent what I would term theories of disease distribution,24which presume but cannot be reduced to mechanism-oriented theories of disease causation.
