Expected COVID-19 cases averted per contact traced

Caption

Expected COVID-19 cases averted per contact traced as a function of lag from specimen collection from the index case to isolation of the contact from Nov. 8, 2020, to May 31, 2021, across a range of contact tracing scenarios, assuming R0=1.2. Left panel and right panel assume 40% and 80% of symptomatic cases are detected, respectively. The blue shading indicates contact tracing success rates of 25%, 50%, or 75%. The points are medians from 200 paired stochastic simulations, and the error bars are the interquartile ranges.
