That WP article's simulation is well done, except for one crucial thing--it does not show the time scale. The last motion graphic showing the spread when only 1 in 8 people move at all, ever, well it just ends when it's starting to really spread. Easy-ish for a mathematician but not for me would be showing when if ever would extreme social distancing and near-perfect mask use by almost everyone result in enough recovered people blocking the spread to as yet uninfected people such that, in the end, much less than 80% of the population ultimately gets covid-19? Meanwhile, the US is at about 50,000 deaths, and at the highest estimate maybe 10% of the population has been infected. That math is easier to do; hard to accept.

Whatever this percentage is does not change the logic here." For those for whom "math" is scary territory, I saw a great visualization in the Washington Post that allows you to see the curve as it develops: https://www.washingtonpost.com/graphics/2020/world/corona-simulator/ cheers, James -------------- next part -------------- An HTML attachment was scrubbed...
