The article makes an excellent argument for the plausibility of indoor airflows being a major transmission vector. But I didn't see anything about ongoing research to quantify the transmission risks posed by aerosols vs. other transmission mechanisms. (Maybe I missed it?) It's hard to make policy recommendations regarding aerosols if (a) we're not really sure how big a risk factor they pose and (b) the mitigations would be very expensive.
