1. The B.1.1.7 variant could prove to be our last major obstacle to achieving containment of the virus in the US. But it isn't getting enough respect. Many states are eliminating their effective mitigation measures such as mask mandates and on gatherings.
2. This variant increases 70-100% every week to crowd out other lineages and become dominant. In Germany, it is presently 5.8% (like San Diego) and here is their projection (via @kakape).
We are in the lull zone.

4. Is B.1.1.7 a variant or a strain?

It's behavior is markedly different from D614G. It clearly qualifies as a strain. While we're at it, on this #SuperBowlWeeknd
, it is surely a superspreader strain since it is unequivocally more transmissible (≥50%)

5. Instead of the Sturgis rally or Rose Garden superspreader events, now the virus is driving its dissemination beyond what people do. That's a worst case scenario. We have seen the toll it has taken in the UK, Ireland, Israel, and Portugal @OurWorldInData
6. B.1.1.7 is here, in every state by now, and it is destined to do the same, in a patchwork pattern. We can't/ haven't vaccinated fast enough to put it into check. Relaxing mitigation now is the wrong strategy. It's denialism (like a year ago), the opposite of what we need to do
7. A bit more on B.1.1.7.
Its immune escape appears to be much less than B.1.351 or P.1; the vaccines are working, but:
Now 2 vaccine trials have shown a drop-off in efficacy compared with the ancestral strain
Novavax 96->86%; Astra Zeneca 84->75%

8. Updated tabular summary of the 3 major variants
9. Preprint today on B.1.1.7 shows current US spread and forecasting of how the patchwork will play out, calls for immediate and decisive action
