... when it’s infection fatality is just 0.6% (CDC estimate based on wide range of studies) and even this rate is so heavily skewed to the elderly?
However, I think people are justifiably fearful, despite these apparently reassuring statistics, because of what it means when they are unpacked.
Survival rates from ICUs are around 60% (though this is improving with time).... So with a 0.6% IFR gives a 1.5% chance of being ill enough to warrant being admitted to ICU.
If crudely, we split the country into the “higher risk” and “lower risk” 10:90, with the deaths very disproportionately occurring in the higher risk group, that higher risk group has close to 15% chance of being admitted to ICU with Covid, with the lower risk group being a fraction of a percent. Again, this is a crude indicative split - none of us know our odds with any certainty.
The higher risk group is therefore working with similar odds to Russian roulette when it comes to being critically ill or dying. Yes, they will probably be ok - but rolling the “Covid dice” and hoping you don’t throw a ‘1’ Is a scary prospect.
Of course, some old and vulnerable will be philosophical about this risk - I hope I would be - but it’s a different prospect for those who are a lower risk who have loved ones who are higher risk, which is many of us. My parents are in their late 70s. They are active, otherwise healthy, whose active participation in the economy will be significantly curtailed if the virus was allowed to get out of control. They would “probably” be ok, but I would be cold and heartless to dismissive of that risk, and am concerned about the childcare we currently rely on them for. My participation would be in the economy would therefore be seriously constrained too, even though my personal health risk is very low.
So all in all, there is a large proportion of the population who are rightly concerned, and those who have been saying the deluded “it’s over” or the naive “get back to normal and isolate the vulnerable” don’t seem to understand.
Don’t get me wrong, I’m not pushing for another lockdown - we should avoid one if we at all can - just that we can’t just dismiss the risks as being so tiny as to be not worth worrying about.
