Has the UK government put out how they came to the 70% greater transmissibility of the mutation? And that it's definitely due to mutation and not behavior or relaxed standards? And what is the nature of the transmissibility? Does it require more distancing to avoid? Lower capacities? Less time in a smaller space?
Without the data, I can't help but wonder if the mutation is being up-played as an excuse to clamp down so Boris Johnson doesn't look as inept for loosening things up. If the mutation has been around awhile (one story I ready this AM said it was also detected in Brazil), it surely has made some rounds.
I'm truly not a conspiracy theory person, but it seems there's a lot of conjecture without much evidence. It seems the story is "This mutation is more contagious! Now, let's research it and see if that's actually true."
WHO briefing right now answered a question on the transmissibility - noting it moved the R0 from 1.1 to 1.5. They were clear that the good news is that is a very manageable number to get under control. This isn't a wildly out of control thing, so much as something that requires a doubling down. More information coming in daily as more research is being done.
No information has changed on how it spreads (still spreads between people in close contact).
For all of our chaos with politics and hospital capacity here, Britain definitely doesn't need this. Hope it all gets better soon!
First, let's put numbers in perspective. That "70%" figure sounds scary. But, it's 70% of a small number, namely, the R-nought number. So, using the example above, an R0 of 1.1 going to 1.5 is an absolute value increase of .4, which is an increase of 36%. If it went from 1.1 to 1.77, that would be a 70% increase. An R0 of 1.77 isn't good, but it isn't apocalyptic.
Second, while this *could be* more contagious, there's no evidence for it, except, for its current prevalence among the strains that exist. That *may imply* greater contagiousness, but not necessarily. As we always say when doing science: correlation is not causation.
Could there be other causes? Oh, yes. How about the geometric curve we're all so familiar with? As we plot the daily number of cases and see the trend line get larger, it suddenly spikes upward. That has happened with all the other mutations of COVID... so why is this spike any different? It's happening everywhere with the older mutations.
I laughed at one of the quoted articles which pointed to this geometric growth of COVID in the U.K. despite lockdowns. Um.... we have geometric growth just about everywhere despite precautions being made. Why? Because people won't stop socializing and going to indoor restaurants and bars and gyms and they think being outside magically protects them from someone next to them without a mask on.
If there is a new strain of COVID that has a R0 closer to 2.0 than 1.0, then all the hygiene precautions we've been doing should still work... if people took them seriously.
