It doesn't matter if we know precisely the details of Covid spread. Obviously that information would help. Irrespective of how Covid spreads - we know for sure that: a) Total lockdown works. b) Contact tracing works. c) If you have 0 cases and you have good borders (like Taiwan), you can keep it out. d) Nothing else works. Option B is our only way to stay alive. Those 'superspreader' references you pointed out will help us refine the terms of 'contact tracing' solution, but probably not abnegate it entirely.
