@_Kodos_ @humftydrumpfty @DrTomFrieden "that means masks now are useless"
This is also false. During the most rapid spread of a new variant with high immune escape (i.e. limited immunity) and sudden reopening, 19% isn't enough to matter much, but once that period of rapid spread passes, that's no longer the case.
@_Kodos\uuU@humftydrumpfty@DrTomFrieden“这意味着面具现在没用了”
这也是错误的。在免疫逃逸率高（即免疫力有限）的新变种迅速传播并突然重新开放的过程中，19%不足以产生多大影响，但一旦快速传播期过去，情况就不再如此了。
