Contemporary epidemiology as a science extends considerably its object of research interest. Originally it was interested in the prevalence of communicable diseases in the population and investigated all the factors, which affected this distribution. In the last few decades, epidemiology passed from following-up of communicable diseases to the description and the analysis of all diseases, which occur on our planet. Because of interest in the diseases, which endanger civilization as a result of its development, is the epidemiology with this target is called sometimes the epidemiology of non-communicable diseases. Traditional and the historical experience of communicable diseases epidemiology, methods of the classic statistics and the epidemiological working method are its basic principles. Adequate design of epidemiological studies and modern indicators for evaluation of the health status are used. Epidemiology does not investigate the disease and the risk factor separately, but they are analyzed mutually at three levels as a relation, association and causality. Emphasis is laid on minimalization or complete elimination of confounding and bias.
当代流行病学作为一门科学，其研究兴趣的对象有了相当大的扩展。最初，它关注的是人群中传染病的流行情况，并研究所有影响这种分布的因素。在过去几十年里，流行病学从对传染病的跟踪研究转向了对地球上发生的所有疾病的描述和分析。由于关注因文明发展而危及人类的疾病，以这个目标为导向的流行病学有时被称为非传染性疾病流行病学。传染病流行病学的传统和历史经验、经典统计学方法以及流行病学工作方法是其基本原则。采用了适当的流行病学研究设计和评估健康状况的现代指标。流行病学不是分别研究疾病和危险因素，而是将它们作为一种关系、关联和因果关系在三个层面上相互分析。重点在于将混杂因素和偏差最小化或完全消除。
