Transmission via aerosols: Plausible differences among emerging coronaviruses

Figures & data

Figure 1. Viability of SARS-CoV-2, SARS-CoV-1, and MERS-CoV in aerosols. Data are from Pyankov et al. (2018) and van Doremalen et al. (2020). Polydisperse aerosols with a size less than 5 μm were tested. Infectious titer for SARS-CoV-2 and SARS-CoV-1 is per liter of air sampled; for MERS-CoV it is per milliliter of liquid with sampled aerosols.

Figure 2. Number of samples isolated with viable SARS-CoV-1 for various size particles collected in indoor hospital air. Data are from Xu et al. (2005). Aerosols were separated into nine size ranges using a cascade impactor. For the smallest size range (<0.43 μm), particles were collected on filters.
