This would give 5-10 million infections in the US or about 2-3% cumulative prevalence. This is a long way from the 50% (R0 of 2) to 66% (R0 of 3) we'd need for herd immunity. 15/18

I see #TestTraceIsolate as the only real solution to the problem we're facing (see recent thread from @firefoxx66 https://twitter.com/firefoxx66/status/1248939530939490304), alongside non-economically disruptive distancing and broad use of masks. 16/18
