Table 5. Cumulative number of cases, deaths, and hospitalizations for 10%, 25%, and 50% of the population wearing N95 respirators when they are 20% effective in reducing susceptibility and infectivity.

The results from three different initial average effective reproduction numbers uncontrolled are shown: Runcavg=1.25,1.3,and1.35.
