UK Covid-19 mortality rate could be just 0.15%

I doubt we'll every know that precisely. People are still trying to figure out how many died from flu in 1918. Here in the US the mortality rate is surely higher than .15 percent. The testing regimen is clearly not counting everyone who's been exposed; it is likely several times higher than the official count. But not yet anywhere close to half the population. And then there are places like Brazil and Mexico, where the disease is clearly rampant and the testing regimens are totally inadequate.

In a similar vein perhaps people have seen a statistic going around about a "0.13% death rate".

The origin of the 0.13% death rate statistic is as follows: On Monday Oct 05 the WHO announced there were 750 million cases of Covid worldwide (see tons of news sources). According to the official WHO tracker there have been 1 million deaths.

1 million divided by 750 million is 0.00133333 or 0.13% IFR.
