Yes, I've seen that reported. I never expected the mortality rate to be as high as the originally quoted 3 - 4% figure, if only because that was based on incomplete data. Neither do I expect it to be as low as 0.02% as quoted on this thread.
We won't know for quite some time what it really is. However, back-of-the-envelope calculations are possible. New Jersey's Governor has just tweeted that SARS-CoV-2 has killed more people in his State in 6 weeks than the last 3 seasonal 'flu outbreaks combined. With the pandemic far from over, that suggests a lethality of at least 3 times that of a typical seasonal 'flu virus.
And that isn't the only relevant factor, of course. SARS-CoV-2 has a far higher infection ratio than typical 'flu. Estimates again vary, but the lowest I've seen is 2.5 and the highest (suggested from Ireland) is 5. 'Flu is typically around 1.3- 1.4. That makes it probably 3 times as contagious as 'flu.
*reaches for back of envelope again*
If you're keen on risk assessment, you multiply the factors. 3 x 3 gives us a figure of 9 - let's round that to 10. That means SARS-CoV-2 is 10 times as high a risk as seasonal 'flu. Or, to put it another way, it will probably put something like *10 times* the pressure on health services if allowed to run free as seasonal 'flu would. Think about that for a moment, especially in the context of headlines that often speak of the NHS "at breaking point" in just a typical 'flu season.
That's what lock-down is about - in this country, at least. If your health system goes into melt-down, more people die from everything. Many more.
Best educated guesses on CFR so far are somewhere between 0.5 and 1%.
