      I think it’s because aerosolization and being inside (low UV) are key to transmission. masks unfortunately cant do much for aerosolization There’s surely other reasons I’m nit thinking of too

      of course masks help against aerosolization, that's just silly. (1) Is a poorly fitting mask with gaps around the side still going to allow aerosols in? Yes. Will it allow in *less* - yup. (2) will it decrease aerosols exhaled? Dramatically. Ergo, decreases in transmission.

      that's a perfectly reasonable hypothesis, in fact I thought the same thing > 1 year ago. then I read the RCTs... the results are really counter intuitive

      here's one from 2015 about cloth vs surgical masks https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4420971/ … a 2020 European review of trials https://www.ecdc.europa.eu/en/publications-data/using-face-masks-community-reducing-covid-19-transmission … a recent one about masks aerosolizing the virus https://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1003205 … I wish masks worked, honestly. I would've bet they might!

      From your second source... I mean if when you read "wearing a mask is likely to help" you understand "it doesn't help" then sure, all papers conclude that they don't. You're just beyond ridiculous. Also countries in Asia say "Hi!" ;)pic.twitter.com/TvaZ5AqdHh

      "Prior to COVID-19, most studies assessing the effectiveness of face masks as a protective measure in the community came from studies on influenza, which provided little evidence to support their use" ;)

      Asian countries also have more prior immunity to coronaviruses - how do you know which of the correlations is causal? you do an experiment. you're assuming the correlation is causal (I'm not)

      Eh? That's not really true, it was a theory that they ~might~ have more prior immunity, but it has been largely disproven at this stage

      that's not what I've seen - > 17yrs ongoing immunity from SARS-1 - SARS coronaviruses naturally more endemic in that region - massive antibody-cross reactivity with common cold (in Europe too, thankfully) what have you seen, specifically?

      Health Nerd Retweeted Prof. Shane Crotty

      Any references for those statements? SARS-1 was a fairly small number of infections, "naturally more endemic" is not supported in the literature, and as for cross-reactivity I'll just link to the expert in the matterhttps://twitter.com/profshanecrotty/status/1293344524731691008?s=20 …

      1/ There are various tweets misinterpreting COVID-19 “pre-existing immunity” and making dangerous claims about herd immunity. Since many of those claims refer to our scientific papers, we will reiterate the facts. @SetteLab @ljiresearch @ScienceMagazine @CellCellPress pic.twitter.com/gCZwFMW1iU
