  Unless Asian countries are erring on the extreme side of caution it seems wise to assume test+tracing is not sufficient for R0<1. Their effective responses all employ techno-authoritarian interventions: wrist bracelets, GPS tracking, publicly releasing travel routes, QR health codes, out of home quarantine etc. This includes democratic countries. There's an ongoing myopia in the west that is failing to fully interrogate the solutions from Asian countries who are doing well in it's full scope and ramifications on liberty and applicability based on appetite for sacrificing liberty. Media is happy to elevate testing and contact tracing, without acknowledging the authoritarian followup. E: I'm just suggesting it's worth discussing the system in aggregate rather than piecemeal.

  Even if R_t is at or just above 1, that still lets us have a slow upwards curve with repeated short lockdowns. The Oxford paper found that given the characteristics of SARS-CoV-2, 60% of people leaving the house would need to use an app like this (not 60% of the whole population). But that is an evaluation of a single measure: phone contact tracing followed by prompt isolation of contacts. If you combine that with other potential measures such as continued closure of high risk environments, potentially public mask wearing, etc. you might be able to get away with less than 60%.
