logarithmic plot of cumulative deaths per million for countries
The beginning of each of these curves is a straight line, the slope of which indicates the doubling rate of the virus in a susceptible population.
The curve starts to bend as the “herd” begins to acquire immunity.

Here’s the same plot for states. Due to variations in population density, herd immunity % can be different for different states, but travel between states tends to equalize that.
Most states aren’t at herd immunity yet, but to think that we aren’t approaching it is foolish.

From the MIT publication @techreview :
“The large number of people already infected with the coronavirus in the US has begun to act as a brake on the spread of the disease in hard-hit states.”

This thread wouldn’t be complete without my tweet from the other day:
an article which describes a possibility in which people will get reinfected, but with a milder response:
