就季节病类型来说,某一种疾病从过去到现在并非一成不变,随着年代的变迁有微小的变化。以往被称为季节病者完全受春夏秋冬四季的影响,即其一年的变化规律具有强烈的季节性。作者经过大约60年的详细追访,了解到某种季节病的规律,不仅与自然条件,而且与人类社会的多种因素有关。总的趋势是随着社会发展而变迁。因此,在某种意义上已往称为季节疾病者其名称原意可以说已逐渐地淡薄了。 In terms of the type of seasonal disease, a particular disease has not changed from the past to the present, and changes slightly with age. Formerly known as the seasonal sick are completely affected by the seasons of spring, summer, autumn and winter, that is, the variation of one year has a strong seasonal. After some 60 years of detailed follow-up, the author learned that the law of a certain seasonal disease is not only related to natural conditions but also to many factors in human society. The general trend is to change as society develops. Therefore, in a certain sense, the name of the disease, formerly known as seasonal diseases, can be said to have gradually diminished.
