@justlikekevin @zorinaq @ianmSC Yes. "Mask mandate" doesn't affect virus. It may have an effect on mask usage (potentially w/lag) which has a downstream effect on virus. Country A may have a mask mandate and country B not, but country B may have higher mask usage. e.g. Japan, I think.
@Justlikeevin@zorinaq@ianmSC是的。“口罩指令”不会影响病毒。它可能会影响口罩的使用（可能是w/lag），从而对病毒产生下游影响。A国可能有口罩授权，B国可能没有，但B国可能有更高的口罩使用率。e、 我想是日本。
