@redbaybound @jolly1766 @jimhubbell6177 @RadioFreeTom Overall studies find about 20% reduction in spread RATE, which isn't the same as number affected. R of 3 will infect most people given time. R of 2.4 will as well (slightly fewer in slightly more time).
@jolly1766@jimhubbell6177@RadioFreeTom的redbaybound总体研究发现，传播率降低了约20%，这与受影响的人数不同。在一定时间内，3的R会感染大多数人。2.4的R也会（在稍长的时间内稍微少一些）。
