Fig. 5: Effectiveness of different screening schedules on identifying SARS-CoV-2 infected individuals.

From: A modeling study to define guidelines for antigen screening in schools and workplaces to mitigate COVID-19 outbreaks

Fig. 5

Mean cumulative proportions of (a) identified SARS-CoV-2 infected individuals, (b) identified SARS-CoV-2 infected individuals by antigen tests, and (c) identified SARS-CoV-2 symptomatic individuals by antigen tests compared to Schedule 0 (third column panels) by the end of the screening programs under different screening schedules varying the proportion of asymptomatic cases and the basic reproduction number. Note that the different color scales in the three columns. Baseline parameter values for screening programs and those for the epidemic are used if not specified: \({R}_{e}=2.0\),\(\,p=0.7\), low sensitivity tests [\(2.0\times {10}^{6}\) copies/mL], 10 days screening, screening initiation at peak phase, 4 antigen tests for each person. The red dots represent the baseline (\({R}_{e}=2.0\),\(\,p=0.7\)). Note that we did not count individuals infected during the screening period.
