The purpose of the present article is to explain the calculation of incidence rates in dynamic populations with the use of simple mathematical and statistical concepts. The first part will consider incidence rates in dynamic populations, and how they can best be taught in basic, intermediate and advanced courses. The second part will briefly explain how and why incidence rates are calculated in cohorts.
本文旨在运用简单的数学和统计学概念解释动态人群中的发病率计算。第一部分将考虑动态人群中的发病率，以及如何在基础、中级和高级课程中最好地教授它们。第二部分将简要解释在队列中如何以及为什么计算发病率。
