COVID-19 Superspreader Events in 28 Countries: Critical Patterns and Lessons https://quillette.com/2020/04/23/covid-19-superspreader-events-in-28-countries-critical-patterns-and-lessons/

By surveying the publicly-available information about super-spreader events, he is determining the major mode of transmission of the virus; large droplets with ballistic behavior, small droplets that form clouds or virus on surfaces. His conclusion, with lots of caveats about the quality of the underlying data, is the first: “Flügge” droplets that when expectorated are mostly affected by gravity. As he says, this has implications for the preventative mechanisms we use, some of which actually act to increase the likelihood of the spread of the disease.

This work should be taken up by others. Good stuff.
