For those who cannot grasp the problem with this variant I have depicted the changes from the original below. The red boxes are mutations in amino acids and the grey are deletions and blue insertions. This is what I feared almost 18 months ago and discussed early this year. This is a massive change.
This becomes a "Wildfire" event as Michael Crichton had noted some fifty plus years ago. Allowing uncontrolled flow of putatively infected persons makes this a population killer bomb. Again our folks in DC are asleep at the switch. Close the borders, test and sequence, and if necessary quarantine aggressively. We need another Ellis Island, it worked a century ago, so why not again.
