Judging by "excess" (above-average) deaths, the second U.S. wave of coronavirus which peaked in July was much less lethal than the first which peaked in April. The third wave, which peaked recently, was likewise much less lethal than the second - though it affected the most states.
According to maps in the attached New York Times report, the first wave in the Spring was concentrated in only 14 states in the Northeast. The second Summer wave was concentrated is 16 states in the South and West. And the third Fall wave was concentrated in 20 Midwestern and Plains states.
It is not that the virus packs up an moves from one place to another, but that hots spots show up in new places, not the same places. Virus outbreaks flare in places not previously much affected, where there is the least neighborhood immunity. By now there are not many hyper-susceptible large areas left to suprise us (new cases and deaths in Maine, for example, should not have been a surprise, given how few had previously been infected there).
What does all this have to so with several hubristic Governors' periodic on-and-off lockdowns and social restrictions?
Nothing.
There's no connection.
