COVID Crush

What is this?

This is a toy model of disease transmission. You can use it to experiment with how staying away from other people can change how a made-up infectious disease spreads in a population. Each of the dots represents a person, and their color shows whether they are healthy (blue), infected but not yet feeling sick or "incubating" (yellow), sick (red), or recovered from disease (grey). The dots move around according to some rules that you can control, and they can give each other the disease when they come close to each other.

Experiments you can try at home

At the top of the simulator, there is a counter of how many people are in each disease category: healthy, incubating, sick, and recovered. When you get to the end of four weeks of simulated time, you'll see what percent of all the dots were infected after 1 month.

How does the simulator work?

The simulator starts with one infected dot. Dots can get infected if they come very close to another infected dot, even if that dot isn't showing symptoms yet.

What are the details, though?

The simulation involves a population of 1000 people, represented as dots, and how they interact in an abstract, two-dimensional space.
