Modelling the spread of Corona virus

The Corona virus has in a very short span wreaked havoc on a global scale. While efforts are on to develop a vaccine against the virus, the best course of action till then is to practice good hygiene and social distancing. In this work, we discuss some quantitative models for the spread of such viruses. These models imply that ‘social distancing’, i.e. a spatial separation of one to two metres between individuals could curtail the rate of spread by increasing the time scale for propagation. We also model the growth, flattening and decay of the curve and these models match with those observed in various regions (countries).
