Yawn - same bullshit, different post.
None of these idiots know ANYTHING about what constituted a "mask" during the 1918 panedmic.
"Unfortunately, Wu’s construction advice was forgotten or ignored by the time of the 1918 flu pandemic. During that time, most people were using very loose fabric, like cheesecloth."

Osterholm has already recognized and highlighted the importance of distancing, despite a lack of randomized controlled trial evidence. And yet if all that mattered really was the aerosol particles that Osterholm is so focused on, distancing would be of little value, since those particles can remain in the air for hours and can wander all around a building. In practice, however, we see that nearly all spreading occurs within a couple of meters of a patient (except in cases such as singing and yelling, where droplets are ejected much further), and the droplets hang around for about 10 minutes. The same observations about real world cases that support the importance of distancing also support the importance of mask use. In fact, the two interventions make an excellent pairing: mask use decreases the radius of the droplet cloud, making distancing more effective.

And multivariate analysis linked mask use to lower mortality and significantly reduced spread.
Purpose To determine sources of variation between countries in per-capita mortality from COVID-19 (caused by the SARS-CoV-2 virus). Methods Potential predictors of per-capita coronavirus-related mortality in 200 countries by May 9, 2020 were examined, including age, sex, obesity prevalence...

Masks: Early Adoption
The World Health Organization initially advised against widespread mask wearing by the public, as did the United States CDC.1,48 The WHO reversed course and recommended masks in public on June 5, 2020.49
Despite these initial recommendations, a number of countries did favor mask wear by the public early in their outbreak, and such countries experienced low coronavirus-related mortality (Table 2, Table A1, Figure 1).50-68,S1-S301 It is likely that in Mongolia and Laos, both of which reported no coronavirus-related mortality by May 9, the public began wearing masks before any cases were confirmed in their countries (Table 2). We identified 22 additional countries with recommendations or cultural norms favoring mask-wearing by the public within 20 days of the estimated onset of the country’s outbreak:1 including (beginning with those favoring masks earliest in the course of their outbreak): Japan, the Philippines, Macau, Hong Kong, Sierra Leone, Cambodia, Timor-Leste, Vietnam, Malaysia, Bhutan, Venezuela, Taiwan, Slovakia, St. Kitts and Nevis, South Korea, Indonesia, Brunei, Grenada, Mozambique, Uzbekistan, Thailand, and Malawi (Table 2). The average mortality by May 9 for these 24 early mask-wearing countries was 1.5 per million (SD 2.0). Twenty of the 24 were lower-mortality countries (p=0.001).
Today, the CIDRAP web site still makes the claim that “sweeping mask recommendations… will not reduce SARS-CoV-2 transmission”. Correcting the record at this point will require an unambiguous, public statement, that these earlier claims were not based on scientific evidence, that they were wrong, and that mask use is a very important tool to combat the spread of COVID-19.
