Looking at R, I'm thinking this is the way to figure out how much COVID is left to deal with once R goes below 1.

If R=.5 (1/2), then the number of COVID cases which will occur is essentially the sum of the series, 1/2 + 1/4 +1/8+1/16 ... which equals 1.

So if there are 5 million cases and R=0.5, there will be another 5 million cases to go.

But if R=0.9, then the series is 0.9+0.81+0.729 ... which means if there are 5 million active cases, there 10's of million more cases still to go.

It really speaks to the need to be very aggressive in driving R down as fast and as furiously as possible. And since our behavior has a lot to do with R, the way we act collectively will remain a big part of the story. The one thing which is clear, just because you get R below 1, doesn't mean it will stay there.
