@MichaelSFuhrer Let's say sensitivity of a survey is 50% and independent of infection ordinal (there are some false positive too, ignored here). 50% of first infections will be picked up, but 50% of second infections will also report as first infections.
@MichaelSFuhrer 假设一项调查的敏感性为 50%,并且与感染顺序无关(也有一些误报,此处忽略)。 50% 的首次感染会被感染,但 50% 的二次感染也会报告为首次感染。
@FinchTH @dgurdasani1 Most likely. The only realistic way to avoid that route would be if respiratory mucosa aren't amenable to infection either at all or with such low susceptibility that it require an enormous dosage. Not "generating aerosols" isn't really a thing.
@FinchTH @dgurdasani1 很有可能。避免该途径的唯一现实方法是,如果呼吸道粘膜根本不易于感染,或者其易感性如此之低以至于需要大量剂量。不“产生气溶胶”并不是真正的事情。
@Mr_Inquisitr @chambersfw1 @LieslMcconchie Yes that's right. I'm assuming this is the Nordic Pure MERV 15 since I don't see the filter level in the photo. The version using the Lennox MERV 16 has even higher CADR but costs a bit more.
@Mr_Inquisitr @chambersfw1 @LieslMcconchie 是的,没错。我假设这是 Nordic Pure MERV 15,因为我没有在照片中看到过滤级别。使用 Lennox MERV 16 的版本具有更高的 CADR,但成本更高。
@LazarusLong13 @D_Bone The Nordic Pure gives you lower CADR but also lower cost. Both seem like reasonable options. The Lennox is carbon coated which might help with odors (or might be worthless in practice, I don't know). It also might last longer.

CADR vs $. In 12/21 as Omicron was approaching fast, I scrambled to finish testing HEPA and do-it-yourself (DIY) built w/ fans and HVAC filters for an apples-to-apples comparison of CADR (cfm), noise (dBA), and cost ($). (6/16) https://www.sciencedirect.com/... https://t.co/i29ON2XPaf
发表时间:9个月前 作者:Devabhaktuni "Sri" Srikrishna @sri_srikrishna@LazarusLong13 @D_Bone Nordic Pure 为您提供更低的 CADR,但也降低了成本。两者似乎都是合理的选择。 Lennox 是碳涂层的,可能有助于消除异味(或者在实践中可能毫无价值,我不知道)。它也可能持续更长时间。

加元对美元。在 12 月 21 日,随着 Omicron 的快速临近,我争先恐后地完成了 HEPA 测试,并用风扇和 HVAC 过滤器构建了自己动手做 (DIY),以对 CADR (cfm)、噪音 (dBA) 进行苹果对苹果的比较, 和成本 ($)。 (6/16) https://www.sciencedirect.com/... https://t.co/i29ON2XPaf
@Lujan588 @phealthsean I heard that in areas where nobody was interested in masks they had good inventory and good selection (even including individual wrapped Aura) for months. Which speaks to the poorly run nature of the program. Masks didn't get to people who wanted them.
@Lujan588 @phealthsean 我听说在没有人对口罩感兴趣的地区,他们几个月来都有很好的库存和很好的选择(甚至包括单独包装的 Aura)。这说明了该程序运行不佳的性质。口罩没有送到想要它们的人手中。
