Uptick
As not totally unexpected, the new infection rate of Corona-virus cases have increased toward the end of the year (Nov 2020).
It seems herd immunity has not progressed as much as we collectively had hoped.
I would suggest the reason for the uptick is largely due to American's fatigue with being locked up and locked down.
People are tired of loss of income, joy of living, weddings, births, travel, celebrations of funerals and much else.
In other words, I/we do not care anymore. The reality is the Chinese Military attacked the world screwing around with a weaponized virus in a military lab they were unprepared and unable to contain.
It seems to me the American people have decided that the war is on with the viral threat and there is nothing else to do but get on with living and an elevated rate of dying. The reason for this is our children seem to be coping with the virus reasonably well, and much better than older ones.
