Our @TheLancet paper is a work of synthesis in the service of a causal framework that best explains observed phenomenon over a year of intense data collection. I'd be interested to read a case for "it's predominantly and/or largely droplets" fits the data. https://twitter.com/dylanhmorris/status/1382827972239843330 …

This is why many of us are in favor of doing away with most of the terminology altogether and sticking to respiratory transmission.

A terminology update might help. Important to get the right size established though, because it has a lot of implications and helps correct errors. (Droplets precautions aren’t useless, for example, but don’t imply dominance of >100 micron particles propelled by gravity).

Anyone who has walked into a department store in which the perfume counters are set near the entrance should have a great appreciation of how aerosols can disperse and suspend.

In 2021 and after a year of the pandemic this just frustrates me. We know the science between droplet size and suspension times for decades. Anyone running a class 10 clean room knows the calibration drill. This stuff is basic 101 - and from the same country with mrna 7 crispr

What does this mean for "6 feet apart"? I thought the 6 feet was based on heavier "droplets"?
-
Yes it was based on that. It means it's nonsense, always was. This document is written by many of the people who have spent the last year dragging the world to a bettrr understanding of how COVID19 spreads.https://tinyurl.com/FAQ-aerosols

I reviewed this paper in Jan 2020. Here's what I wrote: "This work is hugely important in challenging the existing dogma about how infectious disease is transmitted in droplets and aerosols...." /1

"The existing assumption that large droplet transmission dominates at short-range while aerosol inhalation transmission is important only at long-range does not incorporate a modern understanding of aerosol science." /2

) but it's not correct to assume that airborne transmission necessitates either a high R0 like measles or even a uniform transmission pattern. Tuberculosis is airborne but has lowish R0—but likely also overdispersion!
