| 摘 要： | 当一种新的传染病出现时，研究者们往往会用一些流行病学指标来衡量它的传播能力，其中一类重要的指标就是基本再生数(R0)和有效再生数(Re)。然而，R0和Re的定义、计算方法和结果解释等在许多场景中被错误地理解，甚至误用。本文围绕R0和Re的定义、计算方法、两者关系、影响因素、流行病学意义、应用注意事项以及常见传染病的基本再生数等进行综述，为卫生决策部门利用R0和Re制定针对性疫情防控措施提供参考。

| Abstract: | With the occurrence of an emerging infectious disease, some epidemiological indicators are used to measure the transmission of the disease. Basic reproduction number (R0) and effective reproduction number (Re) are two crucial indicators among them. However, the definition, calculation, and interpretation of R0 and Re are misunderstood or even misused in many cases. This review introduces the definition, calculation, influence factors, epidemiology significance, notes for application, and the R0 of some common infectious diseases, aiming to provide scientific guidance for health decision-making departments to prevent and control the epidemic of infectious disease. |
