Evaluating the impact of test-trace-isolate for COVID-19 management and alternative strategies

Analysis of baseline with longer delay varying the time from sample collection to laboratory diagnosis.
A Reduction in the cumulative infections. B True positive rate among the traced individuals. “Tcr = 1 (baseline)” and “Tcr = 4” are the models setting the time from sample collection to laboratory diagnosis as 1 day or 4 days, respectively. “Tcr = 1 (null model)” is the model setting the time from sample collection to laboratory diagnosis as 1 day, but the true positive rate among the traced individuals is the same as the model with “Tcr = 4”. Other parameter settings are the same.
