Main differences between molecular epidemiology and traditional epidemiology

The main difference between molecular epidemiology and traditional epidemiology lies in the different measurement results.

The results of traditional epidemiological measurement are generally the final results of diseases, such as onset and death. According to the principle of natural history of diseases, molecular epidemiology divides the occurrence and development of diseases into different stages, and it is a great development of traditional epidemiology to use a series of biomarker measurements to represent the outcome measurement of diseases in different stages.

Epidemiology is a science that studies the distribution and determinants of diseases and health status in a specific population, and studies the strategies and measures to prevent diseases and promote health. It is an important part and foundation of preventive medicine.

Epidemiology is developed by people constantly fighting against serious diseases that endanger human health. In the early years, infectious diseases spread widely among people, which brought great disasters to mankind. People have conducted in-depth epidemiological investigation and research on infectious diseases and taken preventive measures.

primary mission

The research scope of epidemiology is not only to study the specific measures to prevent and control diseases, but also to study the countermeasures to prevent and control diseases, injuries and promote and protect human health. The research object is the population, including all kinds of patients and healthy people; The main research method is to investigate and study in the crowd.

Its task is to explore the etiology, clarify the distribution law, formulate prevention and control countermeasures and evaluate the effect, so as to achieve the purpose of preventing, controlling and eliminating diseases; At the same time, the task of epidemiology is to prevent diseases and promote health. On the basis of studying the diseases, health status and its influencing factors in the population, we should also prevent the occurrence of diseases in the population, promote people's health and prolong people's life.
