As per the article I posted, many countries did better than us due to having a much healthier pop.
Arguing with you is like shooting fish in a barrel. You never research anything and simply say stupid stuff constantly off the top of your head. Like this latest drivel. The reasonably large countries that have death per capita rates in the <10 per 1MM range (vs. our over 350 per 1MM and 500-800 in Europe) have been able to do that because they have greatly reduced transmission rates and cases, yet their deaths per case ratios are not far from ours. I'm sure health and comorbidities (and age - part of why Italy is so high - no idea why the UK is so high other than maybe not seeing all their cases) matter a bit, but the big differences in deaths per capita, the most important stat, is clearly a strong function of cases per capita.
Country...........Cases/1MM........Deaths/1MM........Deaths/Case.......Tests/1MM
USA.....................6397.................354.......................5.5%....................72,000
Italy......................3908.................566......................14.5%...................71,000
UK........................4316.................611......................14.1%...................95,000
Germany..............2235.................106........................4.7%...................56,000
South Korea...........234....................5.........................2.3%..................21,000
Japan.....................137....................7.........................5.3%....................2,600
China.......................58....................3..........................5.6%.......................N/A
Brazil....................3906................197.........................5.1%....................6,400
And how do these countries have such low case and death rates per capita? Early aggressive testing, tracing and isolating and early/continued mask usage with physical distancing. China is the only one of the three countries with very low deaths per capita that had to go to a lockdown, which is understandable, since they were first to be hit and had no clue what was hitting them (especially with most being told to ignore it early on). SK/Japan never instituted full lockdowns, like most other countries did.
SK tested massively early, along with other interventions to contain the outbreak and hasn't had to test nearly as much since then, given very low transmission rates. So, it's not just testing a lot, but it's really important to test early, which the US completely bungled, thanks to the CDC and the Administration. Japan has never had to test much, since they already had the most active mask culture in the world and ratcheted that up immediately, never having huge outbreaks (yet). Broken record.
Finally, getting back to health/risk factors, most would likely agree that Japan and China have healthier populations than the US, especially with regard to much lower obesity rates (which is well known) - certainly the paper from China had 6% with comorbidities vs. 75% for the US for hospitalized COVID patients. Yet China, Japan, and the US all have nearly identical deaths per case, so clearly that's likely not a big differentiator. SK likely has the lowest deaths per case ratio due to such massive early testing finding many more asymptomatic cases vs. other countries (increasing the denominator).
I threw in Germany and Brazil, just to show two more populous countries that have similar deaths per case as the US, but Germany has far less deaths per capita, since they have - wait for it - far less cases per capita, as they have a lot less transmission than the US. Brazil is rapidly catching up to the US on deaths per capita, sadly - the big difference with them is they simply started later.
I'm sure every country will, at the end of all this, have similar deaths per actual infection, as the virus just isn't that different, country to country, once it infects people; we'd actually be able to see this now, if we had country-wide antibody testing to know the actual number of infections, but we don't, so we have to deal with imperfect data.
That utlimate infection fatality rate is still likely to be 0.5-1.0%, as I've said many times, simply because we know it's around 1.0-1.2% for NY and Spain based on actual deaths and antibody results and the death rates will likely drop some, since it's likely more of the most vulnerable did die in the first wave. Also, those rates will drop hugely, when and if we get a cure/vaccine, obviously - and if that comes in 3-4 months with antibody cocktails, those countries that kept their transmission and death rates per capita so low will then feel like they truly accomplished something by saving all those lives vs. other countries that didn't implement strong interventions early on and/or didn't sustain them.
