摘要：The disease caused by SARS-CoV-2, is called Covid-19, and has become pandemic that must be considered in order to control its spread. Covid-19 can be transmitted between humans through mouth or nose when infectedindividuals sneezes, coughs, or talks. In this paper, we develop a mathematical model that introducing physical distancing and self-precaution in the spread of Covid-19. Dynamical model of Covid-19 spread in this paper consist of five variables: Susceptible, Traced, Quarantine, Infected, and Recovery. The results of its analysis obtained are two equilibrium points, called disease-free and endemic equilibrium points. Analysis of stability at the equilibrium points is determined by basic reproduction number. If the value of basic reproduction number is greater than one, then this dynamic model is asymptotically stable in endemic equilibrium point. Numerical simulation is provided to explain the behaviour of the system and to understand the impact of the physical distancingand self-precaution on the spread of Covid-19 in a population using real data of Covid-19 outbreak in Indonesia. Furthermore, if the level of physical distancing and self-precaution in the population is higher, then contact between individuals is also reduced. Thus, the transmission of Covid-19 infection can be controlled.
