I just ran across this interesting paper.
https://www.pnas.org/content/118/8/e2021830118
I’ve been wondering, ever since the announcement of “super spreaders” and super spread events, whether it is possible to identify individuals most likely to be super spreaders and maybe mitigate their ability to spread. This paper is not a definitive study, but it does seem to identify the characteristics of individuals that exhale more aerosols than the general population and provide some potential mitigation paths.
It may also provide some insight into why the very young don’t seem to be super spreaders as often as adults.
