Then what is the strategy? None is described in this news report:
Allowing the coronavirus to circulate through the U.S. population unchecked in an effort to achieve herd immunity “is not the strategy” of the nation’s federal government, HHS Secretary Alex Azar said.
All pandemics have eventually ended due to herd effects, vaccines (more recently), the virus became less virulent or people just get on with their lives.
It appears there is no strategy at the moment other than continued lock downs and restrictions. I thought they would have articulated that vaccines are the strategy but they said nothing about that.
There is also no goal post nor metrics to know when we have reached a point where life can resume. Are we expected to remain restricted for the remainder of our lives? If that is the strategy than option 4 – “people just get on with their lives” is the actual strategy. (For example, Shasta County, CA is in open revolt on coronavirus restrictions. This may spread.)
