watching now is quite measurable and repeatable.

Once positive #cases reaches 1.5-2% of population (inferred infection rate of 15-20% per CDC and WHO and others) - reach effective herd immunity. T cell cross resistance is estimated around 50%. The combined reistance of these 2 immune response factors in a population exceeds suppression value for bug with Rnaught of 2.5 to 3.

This is proving out in many countries and states.

Im searching for the case that blows this hypothesis out of the water. So far, its solid.

*when one crosses suppression threshold, curves flatten and bend over. Likely never reaching zero.
