论文摘要
不同的国家（有时甚至在同一国家内的不同地区）采取了不同的策略，试图遏制正在进行的Covid-19-19-19。这些混合在可变零件中的社会限制，早期检测和接触跟踪。在本文中，我们讨论了这些成分对流行动力学的不同影响。讨论是在两个简单模型的帮助下进行的，即经典的SIR模型和最近引入的变体（A-SIR，ARXIV：2003.08720），该模型考虑了一系列无症状的感染剂的存在。
Different countries -- and sometimes different regions within the same countries -- have adopted different strategies in trying to contain the ongoing COVID-19 epidemic; these mix in variable parts social confinement, early detection and contact tracing. In this paper we discuss the different effects of these ingredients on the epidemic dynamics; the discussion is conducted with the help of two simple models, i.e. the classical SIR model and the recently introduced variant (A-SIR, arXiv:2003.08720) which takes into account the presence of a large set of asymptomatic infectives.
