Graphics reporter Harry Stevens from The Washington Post helps us see the impact of “social distancing” with this coronavirus simulator. He shows the effects of four simulations — a free-for-all, an attempted quarantine, moderate social distancing, and extensive social distancing.

Harry goes on to say, “moderate social distancing will usually outperform the attempted quarantine, and extensive social distancing usually works best of all.”

To simulate more social distancing, instead of allowing a quarter of the population to move, we will see what happens when we let just one of every eight people move.
