These simulations show the  importance of flattening the curve for coronavirus especially the steep jump in the curve when it grows exponentially as people mingle in crowded environments, on trains and subways, and in public gatherings of more than 10 people. This is shown here in four different simulations in the Washington Post. Social distancing and quarantine worked in China, Taiwan, Singapore and South Korea. Though the attempted quarantine simulation here does not cover the situations in China, Taiwan and Singapore where quarantine has worked and was the only way to tackle the coronavirus in time to do least damage.

Additional simulations would show the way it was limited in Singapore through contact tracing and mandated staying at home for all who have come in contact with affected persons. And in South Korea a simulation could show how this worked through containment by testing and limiting spread, or China by an effective quarantine or lockdown of a city or province. 

The basic idea is to limit contact and separate so that intermingling is restricted to as few places as possible for a limited period during which health authorites can achieve a controlled situation through systemwide organized efforts.
