CORONAVIRUS: INFECTIONS/DEATHS PARADOX

We are told that the death rate from coronavirus is about 1%.  In case you wonder what is behind this "guesstimate," there is nothing behind it.

Consider, the official counts as of April 8 were 426,300 cases and 14,622 deaths.  Normally I would consider the death rate to be the more accurate figure, but we should remember that the death count is only for those hospitalized and does not include those who die at home.  If the death rate is 1%, then the caseload should be 1,462,200 (100 x 14, 622) rather than the published value of 426,300.  So 426,300/(1,462,200) = 0.29%.  That is to say that the death rate is something more like 0.29% rather than 1%.

Let's do it the other way around.  Let's say that the caseload is the better number so if there are 426,300 cases then 1% should be 4,263 deaths (426,300/100), but this calculation is 0.29%, even less (4,263/14,622).

To the best of my knowledge, all death-rate figures come out to be much less than 1%.

 As of April 8, there were 1,508,965 cases of coronavirus worldwide and 88,323 deaths.  If the death rate is 1%, then there should be 8,832,300 cases which would indicate that the death rate is about 0.17%.

As of 04-10-2020, the caseload has topped 518,892 and the deaths have topped 20,109 for the U.S.*  Here the death rate would be about 0.25%
