From: The vaccination threshold for SARS-CoV-2 depends on the indoor setting and room ventilation
Surface graphs of Revent for wild-type SARS-CoV-2 as a function of the number of susceptibles and air exchange rate (AER) for the restaurant (A), classroom (B) and prison cell block (C) modeling scenarios. Contour lines connect equal Revent values. The black- and white-filled points along the Revent = 1.0 contour line identify the threshold number of susceptibles for natural ventilation and mechanical ventilation scenarios, respectively, at the intersection of the dashed horizontal and vertical lines. The threshold values are labeled in parenthesis in terms of both the percent susceptible and m2 susceptible−1
