Abstract
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.
