各种传染病潜伏期的长短有一定的范围,且多属正态分布,但由于影响疾病潜伏期的因素多,因而同一种疾病在不同的时间、不同的地点或单位,以及在不同的人群中,其潜伏期的长短不尽相同,也不一定都属正态分布。如何根据具体情况,正确分析、计算和应用潜伏期,在流行病学的理论研究上和实际工作中都有重要意义。
The incubation period of various infectious diseases has a certain range of length and is normally distributed. However, due to the many factors that affect the incubation period of the disease, the same disease at different times, different sites or units, and different populations, The length of their incubation period varies, nor are they all normal distribution. How to correctly analyze, calculate and apply the incubation period according to the specific situation is of great significance in the theoretical research and practical work of epidemiology.
