Evaluating the impact of test-trace-isolate for COVID-19 management and alternative strategies
Fig 3
Effectiveness and social/implementation cost of TTI.
A Infection attack rate (IAR) without TTI strategy (unmitigated) and reduction in the cumulative infections by the Test-Trace-Isolate strategy (baseline) with different reproduction number R0. The vertical error bars indicate the 95% CI. B as in A, but for the number of deaths per 1,000 people and reduction in deaths. C Peak daily number of traced individuals with positive test results (thus contact tracing is needed) per 1,000 people. D Peak daily number of simultaneously isolated individuals per 1,000 people.
