@mskathleenquinn @greg_travis I'm not sure 90% does much. 10% leakage explodes exponentially relatively quickly (back to 100% in ~3 doublings) The places that were really successful had real quarantines, electronic monitoring, and basically no travel.
@mskathleenquinn @greg_travis 我不确定 90% 做了多少。 10% 的泄漏相对迅速地呈指数级增长（大约 3 倍后恢复到 100%） 真正成功的地方有真正的隔离、电子监控，而且基本上没有旅行。
