@chud_meridian @sigurdbordvik @TheWisestHuman @NateSilver538 It's happening all the time to some extent. For example, right now there are some new sub variants largely limited to upstate New York that appear potentially significant. They're not well understood. Slowing down how fast they end up everywhere is very sensible.
@在某种程度上，它一直在发生。例如，目前有一些新的子变种，主要局限于纽约州北部，似乎具有潜在的重要意义。他们没有被很好地理解。放慢它们在任何地方结束的速度是非常明智的。
