Why the rush to Shut Schools and Large Public Spaces and Events down???

We are in an unprecedented time of shutting many aspects of civilization down around the world, because of the COVID-19 pandemic. But why the rush and urgency???

It is the math and science behind how a disease spreads, which is referred to as exponential growth. Please check out a really well done explanation of what this means, how it works, and how experts use a mathematical model to simulate the spread of a disease. It uses actual data from China to make its point, and you will get the gist of why social distancing and washing hands make such a BIG DIFFERENCE in the number of people who might become infected. For anyone who does math modeling, it also explains sensitivity testing really well.

Please check it out, and gain new appreciation for some of the math you learn in school but might not know how it is applied to the world!
