Effectiveness of isolation, testing, contact tracing, and physical distancing on reducing transmission of SARS-CoV-2 in different settings: a mathematical modelling study
UK study estimates a high proportion of cases would need to self-isolate, and a high proportion of contacts be traced for a tracing strategy to be effective for controlling coronavirus transmission. Combining with moderate physical distancing would increase chance of success.

SPS commentary:
A related commentary highlights the results also suggest that without contact tracing, isolation alone will not result in control of the epidemic. Authors suggest the findings are relevant to all countries.
