Figure 3.

Impact of either using all available Ag-RDTs for symptomatic testing or a majority of them (85%) for community testing in various settings (even distribution only; without quarantine of household members). The proportion of secondary infections averted after 90 days relative to the no-testing baseline for a different number of tests available per 100 000 persons per day and assumed R_e value is plotted for each test distribution strategy. The vertical red line denotes the number of tests required to saturate symptomatic testing demand (Figure 4). Abbreviation: Ag-RDT, antigen rapid diagnostic test.
