Epidemiology is thus the study and analysis of the distribution (who, when, and where), patterns, and determinants of health and disease conditions in a defined population.
It is a cornerstone of public health and shapes policy decisions and evidence-based practice identifying risk factors for disease and targets for preventive healthcare. Epidemiologists help with study design, collection, and statistical analysis of data, amend interpretation, and dissemination of results (including peer review and occasional systematic review). Epidemiology has helped develop a methodology used in clinical research, public health studies, and, to a lesser extent, basic research in the biological sciences.
Major areas of epidemiological study include disease causation, transmission, outbreak investigation, disease surveillance, environmental epidemiology, forensic epidemiology, occupational epidemiology, screening, biomonitoring, and comparisons of treatment effects such as in clinical trials. Epidemiologists rely on other scientific disciplines like biology to better understand disease processes, statistics to make efficient use of the data and draw appropriate conclusions, social sciences to better understand proximate and distal causes, and engineering for exposure assessment.
The term “epidemiology” appears to have first been used to describe the study of epidemics in 1802 by the Spanish physician Villalba in Epidemiology Española.[4] Epidemiologists also study the interaction of diseases in a population, a condition known as syndetic.
The term epidemiology is now widely applied to cover the description and causation of not only epidemic, and infectious disease, but of disease in general, including related conditions. Some examples of topics examined through epidemiology include high blood pressure, mental illness, and obesity. Therefore, this epidemiology is based on how the pattern of the disease causes a change in the function of human beings.
Epidemiology is the study of disease in populations. Epidemiologists involved in preventive medicine and public health professions use epidemiological methods for disease surveillance, outbreak investigation, and observational studies to identify risk factors of zoonotic disease in both human and animal populations. Knowledge of these risk factors is used to direct further research investigation and to implement disease control measures. The use of hazard analysis critical control point (HACCP) systems depends greatly on information produced by epidemiological studies. Epidemiological methods are used for disease surveillance to identify which hazards are the most important. Epidemiological studies are also used to identify risk factors that may represent critical control points in the food production system.
