@FinchTH @exsibilation Not saying it's a bad idea but fit testing is probably less important than good messaging and good designs. Aura has fit test pass rate of >90% assuming people have SOME idea what they're doing (use nose clip properly, etc.)

@FinchTH @exsibilation 并不是说​​这是一个坏主意，但适合性测试可能不如良好的消息传递和良好的设计重要。 Aura 的合身测试通过率为

@FinchTH @exsibilation Oh, and CDC director poisoning the well by anti-selling and saying they're uncomfortable and hard to breathe on TV was probably not helpful either.

@FinchTH @exsibilation 哦，疾控中心主任通过反销售毒害井，并在电视上说他们不舒服且难以呼吸，这可能也没有帮助。

@FinchTH @exsibilation There wasn't a shortage for LONG time before CDC changed the guidance, and even then it was half hearted, confusing, and really poorly implemented (e.g. hospitals making people switch to surgical).
All the rest you said true of course.

@FinchTH @exsibilation 在 CDC 更改指南之前很长一段时间都没有短缺，即便如此，它还是三心二意，令人困惑，而且实施得很差（例如，医院让人们改用外科手术）。
你说的其他所有内容当然都是真的。

@FinchTH @exsibilation It's synergistic with 90% masks too. And still much better.

@FinchTH @exsibilation 它与 90% 的面具也有协同作用。而且还是好多了。

@exsibilation @FinchTH I'm not sure that in some cases with poorly fitting masks the output efficiency isn't worse. On inflow you have the suction effect. But yes it is additive (as is vent/filt). Still, 90% out and 90% in is a LOT better than 30% out and 30% in.

@exsibilation @FinchTH 我不确定在某些情况下，口罩的拟合效果不佳，输出效率不会变差。在流入时，您会产生吸力。但是是的，它是添加剂（就像通风/过滤一样）。尽管如此，90% 的输出和 90% 的输入比 30% 的输出和 30% 的输入要好很多。

@FinchTH @exsibilation Oh I agree even 30% makes a difference. Just saying that I'm not sure usage is the dominant factor at that point, when there is so much more to gain on effectiveness. Going from 70% to 90% usage w/30% eff seems less helpful than from 30% to 90% eff w/70% usage.

@FinchTH @exsibilation 哦，我同意即使是 30% 也会有所作为。只是说我不确定使用是当时的主导因素，因为在有效性方面还有更多的收获。从 70% 到 90% 的使用率和 30% 的效率似乎不如从 30% 到 90% 的效率和 70% 的使用率有用。

@FinchTH I think even with a brace you still need to close the nose clip to have any kind of decent fit, and many people don't do that (also some crappy mass market "surgical" masks have really bad nose clips). May depend somewhat on nose shape.

@FinchTH 我认为即使戴上支架，您仍然需要合上鼻夹才能获得任何体面的合身性，而且很多人不这样做（还有一些蹩脚的大众市场“外科”口罩的鼻夹非常糟糕）。可能在某种程度上取决于鼻子的形状。

@jklmd123 @FinchTH Some of them e.g. Aura are definitely better than very often poorly fitting KN95s that are also often fake.
KF94s seem better at fitting random people reasonably well. Similar in design to Aura may be part of it.

@jklmd123 @FinchTH 其中一些，例如Aura 绝对比通常很不合身的 KN95 更好，这些 KN95 也经常是假的。
KF94 似乎更适合随机人群。与 Aura 类似的设计可能是其中的一部分。

@exsibilation @FinchTH The calculation isn't really clear here when the crappy masks are only 30% or less effective. Even if you somehow got 100% usage, still not all that effective. It's true that the difference between 90% and 95% or 99% wouldn't be that significant.

@exsibilation @FinchTH 当糟糕的面具只有 30% 或更低的效果时，这里的计算并不是很清楚。即使您以某种方式获得了 100% 的使用率，但仍然没有那么有效。确实，90% 和 95% 或 99% 之间的差异不会那么显着。

@FinchTH It's possible that the period when the main advice of "wear a surgical mask with a tight-fitting cloth mask over it" could have been when following the advice (which some did, obviously not all that many) resulted in the best effectiveness in practice.

@FinchTH 可能是“戴上带有紧身布口罩的外科口罩”的主要建议可能是在遵循建议时（有些人确实这样做了，显然不是很多）导致了最佳效果在实践中。

@midnucas @JReinerMD I don't think that's true. Even just from people in the white house who had to test negative to return to work, but there was probably more data than that.

@midnucas @JReinerMD 我认为这不是真的。即使只是来自白宫必须检测呈阴性才能重返工作岗位的人，但可能有比这更多的数据。

@margal @anamika714 @akm5376 Some are.

@margal @anamika714 @akm5376 有些是。

@akm5376 @DyorsMathew Also confusing both with disinfecting. The whole thing is word salad.

@akm5376 @DyorsMathew 也将两者与消毒混淆。整件事都是沙拉。

@IamG_Pa @greta Apparently not enough.

@IamG_Pa @greta 显然还不够。

@chrismartenson Police videos isn't a valid analogy. Police videos are routinely released (if selectively). Sonar tracks are not.

@chrismartenson 警察视频不是一个有效的类比。警察视频会定期发布（如果有选择的话）。声纳轨道不是。

@chrismartenson I dunno, just saying it is possible. They may not be releasable for security reasons, like not wanting to reveal methods. Or it could be all bullshit, I'm not suggesting otherwise.

@chrismartenson 我不知道，只是说这是可能的。出于安全原因，它们可能无法发布，例如不想透露方法。或者这可能都是胡说八道，我不建议其他。

@chrismartenson Some of these could well have been done already, especially analyzing logs.

@chrismartenson 其中一些很可能已经完成，尤其是分析日志。

@uniquenft83 @DeItaone Economy too hot, fed needs to keep raising.

@uniquenft83 @DeItaone 经济太热了，美联储需要继续加息。

@Brainsurfing22 @mildanalyst There are several that use data only from 2020, before vaccines. Stop posting antivax nonsense.

@Brainsurfing22 @mildanalyst 有几个只使用 2020 年的数据，在疫苗出现之前。停止发布antivax废话。

@ShellyFriedland @mehdirhasan We'll see. There hasn't been any 12 month period at even close to 150k so far.

@ShellyFriedland @mehdirhasan 我们拭目以待。到目前为止，还没有任何 12 个月的时间接近 150k。
