One interesting possibility is that the people most likely to get infected (different from most vulnerable if infected) are going to get infected this first round.

What that potentially means is that they will act as effectively a fire-break for the broader population.

Basically a burning of the highest throughput avenues for mass spread.

If true, that would mean we get lots of localized outbreaks, but the probability of that spreading back out into an uncontrolled pandemic is much lower.
