This is mixed news. While this indicates the death rate may be lower and the infection rate higher among the general population, the demographic of individuals in the US military are going to be of significantly higher health than the general population. So, it doesn't necessarily ease the risk for demographics already identified as 'at-risk'. If anything, their risk might be understated given the higher infection ra…

Especially once you consider all of the pre-existing conditions that make you ineligible to be in the military.

I find this to be good even excellent news. It is quite possible the virus is not nearly as dangerous and lethal as people fear. If the young have nothing to worry about the prospects are pretty good. The best way to reach herd immunity is to have lots of immune people around you.

Since about a week ago data has been coming in from antibody testing in Europe... and the results are that IFR (infection fatality rate) is clearly less than 0.5% (0.37% in one city in germany[1]) and the number of actually infected people at least 15 times to 30 times higher than the confirmed number of cases.

There's always the chance that the test itself is not particularly good and just has a high false positive rate. Although it is difficult for a PCR test to produce a match if there is no genetic material present, it may amplify trace signals, depending on the cutoffs chosen.

It does, the more young healthy people are immune, the less likely the virus will make it to them.

Earlier quoted context omitted.

Yes. Many institutions test only if preparing to admit. Anybody else is told to go home and recover in isolation.

if the US has 33K deaths and the death rate is 0.6% then the US must have at least 5 million cases. If the death rate is lower (most likely around 0.3%) then it means 10 million infections. Also a good news actually.

Agree, though still a long way from herd immunity, which I understand starts at 50%-ish.

Note though that the study, its methods and especially its politically charged presentation by repeat social media offenders are still disputed [1]

this is a really good point. AFAIK, 100% of the canonical pre-existing conditions which are highly dangerous with COVID are disqualifiers for joining the military.

this cohort will give us a much better picture of how the virus impacts a totally healthy and young population. as with countless other pieces of evidence, it should also help to put the "it's just a flu bro" falsehood to bed.

I'm not so sure that's clear yet. Just going on blunt metrics, the virus has already killed 0.1% of NYC's entire population, probably on pace to hit 0.2% if the down-curve even only roughly matches the up-curve. So it would have had to have spread to 50% of the population for the fatality rate there to be only 0.4%, which seems unlikely (there's only a smattering of antibody data around the world so far but nothing has found spread even close to 50%, especially at the level of a metropolis)

Do we know if these cases are truly asymptomatic or just presymptomatic as was observed on the Diamond Princess?

48% asymptomatic initially: https://www.niid.go.jp/niid/en/2019-ncov-e/9407-covid-dp-fe-...

18% asymptomatic retrospectively: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7078829/

Also, 58% of asymptomatic COVID-19 infections still show damage to the lungs on CT: https://appliedradiology.com/articles/study-investigates-dia...
