@bidens_diaper @J_D_Klein @HalCranmer "How much damage is masking doing to our natural immune system"
None that you can demonstrate with any evidence whatsoever.
Kids don't mask 24 hours a day anywhere ever and if they want to eat dirt they have plenty of opportunities to do so.
No sign of harm in Japan etc.

@bidens_尿布@J_D_Klein@HalCranmer“掩蔽对我们的自然免疫系统造成了多大的损害”
没有任何证据可以证明。
孩子们从来没有在任何地方一天24小时都戴口罩，如果他们想吃脏东西，他们有很多机会这样做。
在日本等地没有受到伤害的迹象。

@dave_m_ You may be right, but there are many different factors.
Mask wearing is also much lower in places that dropped mask mandates and then brought them back, so 🤷

@戴夫：你可能是对的，但有很多不同的因素。
在那些放下口罩然后又把口罩带回来的地方，戴口罩的比例也要低得多，所以🤷

@murchiston @TheLincoln Yes, also communities even if not dense cities, that are near forests or other flammable vegetation. These areas are all usually more highly regulated in terms of fire prevention.

@murchiston@TheLincoln是的，即使不是密集的城市，也有靠近森林或其他易燃植被的社区。在防火方面，这些区域通常都受到更严格的监管。

@dave_m_ I can't account for what any local area does, but a lot dropped mandates when cases were low and brought them back in December when cases rose again.
CDC recommends universal masking when cases are substantial or high.
Probably should be more focused on high-risk venues too.

@dave_m_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _。
疾病控制与预防中心建议在病例较多或发病率较高的情况下进行普遍掩盖。
可能也应该更加关注高风险的场馆。

@bidens_diaper @J_D_Klein @HalCranmer I don't know why that has never been suggested. I've suggested in to people personally.
That doesn't mean "nobody" does it correctly or even close. A lot of people don't have facial hair, for example. That is likely more effective.

@拜登尿布@J_D_Klein@HalCranmer我不知道为什么从来没有人建议这样做。我已经亲自向人们提出了建议。
这并不意味着“没人”做得正确，甚至是接近。例如，很多人没有面部毛发。这可能更有效。

@bidens_diaper @J_D_Klein @HalCranmer Often there not just confounding but directly offsetting factors. Mask mandates and mask wearing often higher in higher risk communities or when spread increasing or when variants or surges anticipated.
Some good discussion here

@bidens_尿布@J_D_Klein@HalCranmer通常不只是混淆因素，而是直接抵消因素。在高风险社区，或当传播增加，或当预期出现变异或激增时，口罩要求和口罩佩戴率往往更高。
这里有一些很好的讨论
https://twitter.com/zorinaq/st...

@bidens_diaper @J_D_Klein @HalCranmer That's not true in general. If you cherry pick some studies you can find some that say that, others disagree.

@拜登斯尿布@J_D_Klein@HalCranmer一般来说不是这样的。如果你仔细挑选一些研究，你会发现一些研究表明了这一点，其他人则不同意。

@dave_m_ The risk level of the person wearing the mask doesn't matter very much. The purpose of mask mandates and widespread masking generally to reduce the intensity of transmission. Whether at high or low risk personally, people can still spread.

@戴夫：戴口罩的人的风险水平并不重要。口罩的目的通常是为了降低传播的强度。无论个人风险是高风险还是低风险，人们仍然可以传播。

@dave_m_ @MDaware @beyerstein I'm telling you it doesn't make much difference if the people masking are vaxed or unvaxed.
CDC tried that in May '21. After eventually facing reality, they dropped vax status as being relevant in areas of moderate or high transmission. The same is even more true today.

@dave_m_u@MDaware@beyerstein我告诉你，如果人们的伪装是VAX或UNVAX，这没有多大区别。
疾控中心在5月21日尝试过。在最终面对现实后，他们放弃了vax在中度或高度传播地区的相关地位。今天的情况更是如此。

@dave_m_ @MDaware @beyerstein The conclusion doesn't follow but even if it did, that's irrelevant. Both vaccinated and unvaccinated are contributing to high spread and to large, highly disruptive surges.

@dave_m_u@MDaware@beyerstein结论并不成立，但即使成立，也无关紧要。无论是接种疫苗还是未接种疫苗，都会导致高传播率和大规模、高破坏性的激增。

@DailyJLee@JamesSurowiecki这里列出了一些

@jeremychrysler @MelpomeneMel Not sure where was restricted at all, and I don't think anywhere in New England even had mask mandates, perhaps at local level and individual businesses (which isn't really a "mandate" or "restriction").

@jeremychrysler@MelpomeneMel完全不确定哪里受到了限制，我认为新英格兰的任何地方都没有面具授权，可能是在地方层面和个体企业（这不是真正的“授权”或“限制”）。

@bidens_diaper @J_D_Klein @HalCranmer Universal (also called two-way) masking is more effective than PPE because it first reduces the amount of virus in the environment and then amount inhaled from the environment. CDC mannequin study w/shitty cloth masks measured this at 72%->almost 4x exposure possible.

@bidens_尿布@J_D_Klein@Halcramer Universal（也称为双向）掩蔽比PPE更有效，因为它首先减少环境中的病毒数量，然后减少从环境中吸入的病毒数量。CDC人体模型研究（带破布面具）测得这一比例为72%->；几乎有4倍的曝光率。

@bidens_diaper @J_D_Klein @HalCranmer There's often moderate exposure and not everyone in the same location at the same time gets infected.
Various studies show community masking reduces overall transmission rates by about 25% if everyone does it. Since compliance is usually not 100%, the observed effect is smaller.

@bidens_尿布@J_D_Klein@HalCranmer通常有中度接触，并非所有在同一地点的人都在同一时间感染。
各种研究表明，如果每个人都这样做，社区掩蔽会降低总传播率约25%。由于顺应性通常不是100%，观察到的影响较小。

@ThomasTell @Trending2Tee @RadioFreeTom @mehdirhasan Probably not from CDC or even the US. Terrible at collecting data. States report some of it.
Some analysis in this thread
https://twitter.com/wsbgnl/sta...

@ThomasTell@Trending2Tee@RadioFreeTom@mehdirhasan可能不是来自CDC甚至美国。收集数据的能力很差。一些州报告了其中的一些。
这篇文章中的一些分析
https://twitter.com/wsbgnl/sta...

@ThomasTell @Trending2Tee @RadioFreeTom @mehdirhasan These charts are out of date and also out of line with death data which have showed about 20% vaccinated for quite a while. Might be higher now (hard to tell in real time).

@ThomasTell@Trending2Tee@RadioFreeTom@mehdirhasan这些图表已经过时，也与死亡数据不符。死亡数据显示，大约20%的人已经接种了疫苗。现在可能会更高（很难实时判断）。

@jeremychrysler @MelpomeneMel (A few vaccine mandates too, but at least on the left, those calling for "remove restrictions" often want to keep those.)

@jeremychrysler@MelpomeneMel（也有一些疫苗授权，但至少在左翼，那些呼吁“取消限制”的人往往希望保留这些。）

@jeremychrysler @MelpomeneMel The North has been unrestricted since the summer too, except for a few mask mandates, and most of those were absent during part of the summer too.

@jeremychrysler@MelpomeneMel自夏季以来，北方地区也没有受到限制，除了少数几个面具授权，其中大部分也在夏季的部分时间缺席。

@bidens_diaper @J_D_Klein @HalCranmer Mitigating transmission is not the same thing as hazardous material PPE. If you reduce transmission by half, that's enormously beneficial. Reducing silica inhalation by half is a failure.

@bidens_尿布@J_D_Klein@HalCranmer缓解传播与危险品PPE不是一回事。如果你将传播减少一半，那将是非常有益的。将二氧化硅吸入量减少一半是失败的。

@MelpomeneMel When? Will?
All the restrictions except a few mask mandates and international travel rules were lifted long ago.
The answer to what will happen is look around. This is it.

@梅尔内梅尔什么时候？将
除少数口罩规定和国际旅行规则外，所有限制早就取消了。
答案是环顾四周。就是这样。
