Not an answer, but fwiw, my impression is that there’s reasonable odds of at least some aerosol transmission, not just large droplets when coughing. Although I concede that close-contact during symptomatic periods (or a few days before/after) is probably the primary transmission mechanism, especially given how much it seems to circulate in families.
CIDRAP mentions that we don’t know that 6 feet is sufficient, and that aerosol transmission has been seen in MERS (a different coronavirus).
This preprint on surface survival mentioned that SARS-CoV-2 (which they called HCoV-19) seemed able to survive in an aerosol for several hours and remained viable (although also note gwillen’s comment on this.)
This seems like a reasonable question, especially given the extent to which we’ve seen cruise ships (where adequate ventilation is apparently challenging) get incredibly infected.
