However, the virus would of been suppressed and eliminated as Australia has done in every municipality. If that was done say a year ago, the second half of last
year would be virus free and the world today would be like 2019 covid free.
No No NO.
That is not how it works. The virus would still exist and as soon as there is movement then it spreads. That is the point. It is impractical to expect to eliminate Covid. It is like trying to eliminate influenza, another corona virus, or the common cold. It is virtually impossible. That is why the talk was about "flattening the curve" to protect the health system. Then a few months ago there was a subtle shift to trying to eliminate the virus. Which is crazy talk.
PS. Australia has NOT "eliminated the virus in every municipality".
