The importance of the SIR model is needs of an hour, due to COVID-19, HIV, Dengue, Hay-fewer and many more infectious diseases, in analysis and building of the Compartment model in which S-I-R; it stands for the Symptomatic-Infected-Recovered, When we need to build this model for our own country, we need to observed the PEAK prevalence (i.e. maximum number of symptomatic people during the epidemic), need to be considered, studied and analyzed. This course found to be helpful in order develop and build combination of paper-based and computer-based modelling, with the parameters their estimated values like R0 which is basic reproduction number, and so on.....thanks
