Some actual lab work? I’m not a biologist so I can’t give you specific assays. The TWiV team might, I’ll submit a question. If you look at the data behind the NERVTAG report it’s extremely noisy, and is circumstantial. Nothing in there directly measures the viruses ability to spread.
We’ll have to wait for actual science to come in to answer that. They’re just making inferences from epidemiology and gene sequences. None of this actually does anything to confirm their hypothesis.
30% of people infected not able to walk a block without losing breath and being exhausted for a day — that’s enough evidence to say the risk profile has changed.
Infection rate does not change outcome of recovery (unless it’s resource constrained like vents or meds) and to that point — we’ve walked back the immediacy of vents because they were actually harmful to recovery. So technically the resource management argument should be reduced in weight by some factor.
(Sorry GP) asked a personal opinion question and I offered one —
My gut feeling tells me this pandemic is suffering from a similar phenomenon in user interface latency. The research shows that if the latency is under a few hundred milliseconds, we believe that we are in control of the device and our cause and effect matters. However, if the latency is longer than some hundred millisecond mark, we think the device is under someone else’s control and that our cause has no effect on the system — though in fact, it is the direct cause.
To me, a pandemic kinda follows the same thought — if the disease isn’t having a direct, somewhat immediate effect (intuition says a couple days) to our actions, then it’s hard to issue broad, population level behavioral change that comes with direct costs to life and property - it’s just beyond the timeline for us to accept our actions (not wearing a mask or not distancing) as meaningful inputs to the pandemic system.
Personal opinion: I have no trouble wearing a mask even after having covid, but the current gov’t approach is 100% not the way I’d approach this issue. I would approach the mask mandates and business shutdowns this way only if the disease symptoms were severely impacting (so that’s my symptom description with walking a block) a large set of the population (so that’s the 30%, no age brackets needed) — and to me, that number is about 1 in 3. Now the counterpoint to this, is that if there is a tipping point in the proposed pandemic that once it gets to a certain spread, it becomes that 1 in 3 statistic - but I digress, you get the point I believe.
Edit: to tie this all together — there’s a lot of talk about increased sanctions from this new variant — but if the severity of symptoms do not change, only the transmissibility - it is a dangerous seed to sow amongst an already incredulous population.
