Except for two things:
a) that corona spreads through aerosols which we have known since mid 2020
b) Mask don't even work against Influenza which actually is transmitted via droplets.
- buildbot 4y agoA - masks reduce aerosols as well: https://www.nature.com/articles/s41370-021-00385-7 https://www.nature.com/articles/s41370-021-00385-7 B - They do: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7169241/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7169241/

First, they sang with previously inhaled vapor of e-cigarettes. The emitted cloud was recorded by three cameras to measure its dispersion dynamics. Secondly, the naturally expelled larger droplets were illuminated by a laser light sheet and recorded by a high-speed camera." Are you serious? B: Have you even read through your own link? CRCT: "No difference was found between hand hygiene or hand hygiene plus face mask in household contacts of influenza patients" Case-control study: "No marked reduction in infection" Cohort-Study: "The use of masks does not seem warranted if other infection control procedures such as handwashing are used" It was well known before 03/2020 that masks don't do anything. That's why every public health expert and official was adamant that they don't do anything. That's why nobody had any. Didn't you ever wonder why no one had PPE on hand if it's so important? Here is the 2018 review of this topic by the WHO: https://apps.who.int/iris/bitstream/handle/10665/329439/WHO-WHE-IHM-GIP-2019.1-eng.pdf?sequence=1&isAllowed=y https://apps.who.int/iris/bitstream/handle/10665/329439/WHO-... On page 25 you can find a table of RCTs that show exactly how useless masking is vs Influenza. People who "follow the science" seem to be particularly unclear about positivism and the scientific method. Whoever is making huge claims about masks, lockdowns and vaccines needs to understand that burden of proof is on them. THEY need to present a theory that is consistent with ALL of the quality data that exists, not just some cherry picked retrospective garbage from China.
