This simulator will let you see how social distancing can affect how a virus spreads through a population. Each time that you run it, you will get different results, but the pattern will be that staying put helps people stay healthy. This is JUST a simulation and has a lot of random factors. It is designed to be used as an introduction to computer modeling and in no way reflects any real data regarding covid-19 or any other virus.
