What is the difference between epidemiology pathogenesis?
Answers:
The study of pathogenesis, as commonly practiced in biomedical research, is markedly NOT part of epidemiological study. Epidemiology is the study of factor that are associated with disease incident, such as dietary factors, infectious agents, or genetic factor. Pathogenesis is the study of the mechanism of disease causation. Epidemiology may elevate questions that the study of pathogenesis might answer, and vice versa.
As a spur-of-the-moment example, epidemiological studies indicated in the impulsive 1980s that there be an unusual cluster of Kaposi's Sarcoma occurring. Kaposi's was previously described epidemiologically as human being associated with age, femininity, and particular ethnicities. This spanking new cluster was characterized epidemiologically as one associated with youthful homosexual men. Further epidemiological studies suggested a strong association between the appearance of Kaposi's and infection with a untried virus, HIV.
The study of HIV pathogenesis indicated the particular mechanism by which HIV infection caused Kaposi's sarcoma- profound dysregulation of the immune system. This finding of a pathogenic apparatus supported the hypothesis generated by the epidemiology, that HIV infection increased the risk of developing Kaposi's Sarcoma.
Pathogenesis individual discusses the history and evolution of a disease. Epidemiology deals beside all aspects of researching a general spread medical problem, from origins, to treatment, to coping with the disease, to prevention. Pathogenesis falls in the scope of epidemiology.
