Everyone should read this article NOW. It is long and contains lots of numbers and graphs, but it explains everything well, every step of the way.
If you want the short version, it is that we must reduce the transmission of the coronavirus, and the best way to do that is through social distancing, which means shutting down any place where people gather, and putting at least a meter (and preferably 2) between you and any other people. Or even just staying home. Now.
I cannot stress enough that these measures must be taken now. Every day that we delay taking measures will increase the number of cases of COVID-19 by a whopping 40%.
That’s right. 40% every day. That is how exponential growth works. For 40% growth per day, in just a week there are 10 times as many cases, two weeks means 100 times.
And when there are too many cases, the health system becomes overwhelmed and people die.
This is all based on the best numbers we have now, and you can look at the numbers and helpful graphs yourself.
And don’t panic. It is very reassuring to know that there is something straightforward that all of us can do, which we know will work.
If you think you can’t take measures now, know that if you don’t do it now, you will do it later, when it will be much worse. Do it now.

UPDATE: Washington Post has a “coronavirus simulator” which shows (simplified) simulations of COVID-19 spreading under different conditions, including with nothing done (very bad), closing borders in a forced quarantine (works a little, but not very well, and causes lots of problems), social distancing (works much better, as that other article predicted, and how well it works increases as more of the population practices safe social interactions. The percentage of people who practice social distancing can be improved by doing things like closing businesses and other places where people tend to interact closely.
