流行病学译自英文“Epidemiology”epi是希腊语“之间”之意,demi“人们”之意,即研究人们之间流行病的学问。二十世纪以来,一些国家基本上控制了某些传染病的流行,降低了死亡率,因而使得非传染性疾病死亡率在死因构成中占有重要位置。本世纪五十年代以来,由于工业发展,能源改变,人口增加,环境污染日趋严重环境负荷量达到空前程度。急、慢性公害病屡有发生,为了探索病因,制订预防措施,流行病学研究占有重要地位,并得到空前发展。
Epidemiology Epidemiology is the Greek word for “between”, the demi “people” meaning, that is, the study of the epidemic between people learning. Since the twentieth century, some countries have basically controlled the epidemic of certain infectious diseases and reduced the death rate. As a result, the mortality rate of noncommunicable diseases plays an important role in the cause of death. Since the 1950s, due to industrial development, energy changes, population growth, environmental pollution has become increasingly serious and the environmental load reached the unprecedented level. In order to explore the etiology and make preventive measures, epidemiological studies occupy an important position and have been developing unprecedentedly.
