  well no, you write about surfaces (also called fomite transmission). Aerosols are a totally different topic. Please see the historic, massive outbreak of SARS-CoV-1 in Hong Kong Amoy Gardens. There, the aerosols from stool caused a massive outbreak in the whole building and several neighboring buildings.

    Ah yes, you are right, my previous comment is not applicable here. A relevant datapoint here is the case of Webasto in Germany. The woman who infected employees of Webasto and thereby unwittingly created one of the first clusters in Germany was traveling, ate in restaurants etc. Yet the only known infections happened with her colleagues at Webasto, ie those with whom she sat in proximity close and over an extended period. That indicates that infection „requires“ (or is favored) by extended proximity. It may also indicate that infection by aerosols is more „difficult“ and droplets may be more relevant —> masks! I am writing this not to say all-safe but to caution against overexcitement/-anxiety/panic. Caution is good but it seems infection is not as easy or fast as mainstream media are touting atm.
