      What part are you disagreeing with? You asserted that close prolonged contact is supported by vast epi lit. The higher concentration of aerosols near field has been demonstrated and documented widely. As a lay person, I don’t understand the disconnect.

      Can you please read our paper (including the supplementary information) and explain how droplets would have explained 53 infections for the Skagit choir? It's absurd.https://onlinelibrary.wiley.com/doi/10.1111/ina.12751 …

      You said "I am highly skeptical of the assertion that aerosol transmission is a necessary cause of superspreading events" We investigated the choir on it was obvious that the large majority of the cases were airborne transmission. Pls explain why not, if you disagree.

      And please provide a peer-reviewed study of any superspreading event that has convincingly shown that droplet transmission was the culprit. I have not found any, and I have been looking for a year.

      No, my argument is that all of the ones that have been studied and peer-reviewed and published point to airborne transmission. I have not found any that points to droplets. Let's use Occam's razor...

      And why is the burden of proof not on the proponents of droplets? If they were dominant, would not the evidence be plentiful and easy to find? Why then do you have to keep avoiding the question, and not providing any evidence whatsoever?

      Droplet precautions overlap with short-range aerosols but not vice versa. Curious what you think explains the stark outdoor/indoor difference? That, along with clusters+presymptomatic transmission, are the strongest discriminators for me arguing against gravity/droplets as key.

          Yes, "droplet precautions" is a misnomer. They should be called "droplet precautions and pretty-good but not perfect aerosol precautions." Not perfect bc as we mention in @TheLancet, HCWs have been infected despite droplet precaution: https://doi.org/10.7326/M20-567

          So we go back to the same point, droplet precautions is not really evidence of droplets. There is just no evidence of droplets that holds any water...

          Well-worn surgical masks filter the majority of the aerosols but not all. So it makes sense that transmission would be reduced with so-called "droplet precautions" but not eliminated, in accordance with the evidence: https://doi.org/10.7326/M20-567
