Various features of an outbreak change as a function of 1/k (where k is the rate of decay of SARS-CoV-2 survival in the environmental compartment): to (A) ${\mathcal{R}}_{\mathit{0}}$, (B) total number of infected (and symptomatic) after 30 days of outbreak, (C) time to peak number of symptomatic individuals (t_max), and (D) peak number of symptomatic individuals. The black dashed lines show the value of the respective plotted value at the average value of 1/k (~ 1.5 days), used in the fits from above. The top red line shows the maximum of plotted value for either the smallest value of 1/k chosen ( = 1 hr) or the largest value of 1/k chosen ( = 3 days), depending on whether the plotted value decreases or increases with 1/k, and the bottom red line shows the plotted value at the other extreme of 1/k.
