      Fascinating thread from an aerosol scientist, also talking of a forthcoming preprint exploring a compelling case I heard from multiple scientists about a major scientific error by WHO in their transmission mode documents. These details aren't minor issues.https://twitter.com/jljcolorado/status/1295524565179748352 …

      Germany (and some other European countries) are rapidly moving to acknowledge the importance of ventilation and updating their advice. It's way way way past time for the WHO and CDC to update us with proper guidance, beyond broad generalities.https://twitter.com/jljcolorado/status/1296251453296664576 …

      One of the most thoughtful academics on this, @jljcolorado writes a long article making the case for aerosol transmission, *emphasizing* how outdoors is much safer and that's part of the evidence. Then he has to go back and have the picture changed because.. yeah, you guessed it. pic.twitter.com/sCdb6d30CL

      Here's the article by @jljcolorado that compiles a lot of evidence about aerosol transmission playing a role for COVID, with practical takeaways. (I genuinely don't know what it will take for news media to stop with the obsession with outdoor pictures.)https://time.com/5883081/covid-19-transmitted-aerosols/ …

      Also important, by @DKThomp. Some activities are worse than others: talking, singing, huffing and puffing. We should learn from countries that have guidelines for indoors (library rules: keep it low!)https://www.theatlantic.com/ideas/archive/2020/08/wear-your-mask-and-stop-talking/615796/ …

      Consequences of lack of proper guidance on ventilation. This restaurant has blocked *outdoor tables* with plants as per NC guidance, but has reduced seating inside. Everyone should be outside! These tables are far enough.(Place is otherwise well-organized; staff all masked etc.)pic.twitter.com/sG4JRekJQq

      CDC? WHO? We still don’t have ventilation integrated into our guidelines. People are being told to wash their hands, but not open their windows. It’s September 2020.https://twitter.com/adamhamdy/status/1304120806943928329 …

      Dr Anthony Fauci explains scientists have got it wrong for many years, that aerosolised particles can linger in the air much longer than previously thought, and singing and speaking play a significant role in transmission. How long will it take the UK government to catch up? pic.twitter.com/L8b6AvwD0A

      UPDATE! CDC has *finally* explicitly acknowledged the role of aerosols, airborne transmission and the importance of ventilation for COVID. Now urgently waiting for specific guidelines. (Japan had them since February!) Woot! (Hopefully, WHO soon as well). https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/how-covid-spreads.html …pic.twitter.com/btHcplh34w

      Thanks for this. I have people urgently pushing me to allow singing in church. We do wear masks. But this kind of guidance can't come quick enough.

      Yes. Even with masks, I'd be wary of singing indoors. Sing in their hearts, maybe, but not with their voice in an indoor setting with so many around.

          And all masks are not equal when airborne transmission. Look for ASTM-2 ones or with a 98% PFE if you intend to have long indoors encounters.

          Yes! And cloth masks NEED FILTERS; avg cloth mask provides 10% filtration efficiency. PM2.5 filters only protect against dust particles 2.5 microns+. Covid particles in aerosols range from 0.1-0.3 microns. This filter provides up to 95% FE at 0.3 microns http://Nanotech95filter.com
