Superspreading events suggest aerosol transmission of SARS-CoV-2 by accumulation in enclosed spaces

Viral transmission pathways have profound implications for public safety; it is thus imperative to establish a complete understanding of viable infectious avenues. Mounting evidence suggests SARS-CoV-2 can be transmitted via the air; however, this has not yet been demonstrated. Here we quantitatively analyze virion accumulation by accounting aerosolized emission and destabilization. Reported superspreading events analyzed within framework point towards aerosol mediated SARS-CoV-2. Virion exposure calculated these found trace out single value, suggesting universal minimum infective dose (MID) that comparable MIDs measured other respiratory viruses; thus, consistent levels their commensurability known aerosol-MIDs establishes plausibility Using filtration at rate exceeding destabilization reduce below dose.
