61 / 170,575 = .04% fatality rate
And I think I came across another report anecdotally indicating a .05% fatality rate for people under the age of 65. These numbers are inconclusive and skewed if those who are vulnerable are taking extra precautions, if there are hospital patients yet to die, unconfirmed deaths, etc.
LA study concluded that, in early April, there had been 28-55 times as many confirmed cases. Testing is likely wider-spread in Mass at the moment, and the "lockdown" has been in place for longer. In NYC, antibody testing suggests that there are 9-10 times as many cases as confirmed. Mortality rate between ages 18-64, by the official numbers as of maybe a week ago, was 3.6%. If the actual rate is nine times lower, your estimate of .04% checks out (edit - I'm stupid - it would be 0.4%...albeit the situation in NY isn't all too comparable to elsewhere and this is assuming an even distribution of undiagnosed cases).
There are about 215 million Americans between the ages of 15-64. If ~70% are infected (herd immunity), then a .04% mortality rate results in 85k deaths in this age range. 0.1% would give us more than 200k deaths. If no immediate cure or vaccine, we probably see between 30k and 250k deaths in this group, albeit with an estimate towards the lower end of that scale.
I get that or otherwise agree that healthy younger folk should not worry about dying from this virus, but a number of them have died and will continue to die. Then, not everybody who is older or otherwise vulnerable is able to just quit their jobs, or what not (and the federal government, if not also state governments, have not taken many actions to remedy this, many don't qualify for unemployment if they quit, some can't get health insurance if they quit). Others who can afford to stay home will still go grocery shopping, I presume, and many won't be literally willing to quarantine themselves for months on end. So they are still likely to cross paths with younger folk.
All I'm saying. In a sense, it's semantics. I know you aren't saying we should open back up with caution to the wind, and I'm not sure I disagree with you at all.
