Fig. 3: Effectiveness of different screening schedules on identifying SARS-CoV-2 infected individuals under baseline setting (Re = 2.0, p = 0.7).

Mean cumulative proportion of SARS-CoV-2 infected individuals by the end of screening programs. We used baseline values for screening programs (i.e., low sensitivity tests [\(2.0\times {10}^{6}\) copies/mL], screening initiation at peak phase, and 4 antigen tests for each person). The black and pink bars represent identified individuals by antigen tests and symptom screening, respectively. The gray horizontal dashed line means Schedule 0.
