The bottom line though is that the R0 number - yes, I know, you think it's nonsense
I don't think it's nonsense in the abstract, but with a virus that is very non-dangerous to the vast majority of people it's kind of irrelevant.
I kind of get the idea it was chosen in Ireland as a toy to make people feel safe... as it is, it's probably not the worst idea to go for herd immunity* (while doing what can be done to protect the vulnerable)
If the virus were more... consistent in being life-threatening or even made a larger percentage of people seriously ill then it would be a lot more important.
I'm choosing the running hospitalization and daily fatality rates because those are harder to conceal** (I do realize the delay in deaths happening vs being reported and put into the totals).
Policy in many countries is still based on fears from early March when it seemed far more deadly than it has proven to be (and far more contagious than it appears to be).
Where are you getting your current number? The resource I was using hasn't been updated since May 13.... :(
*which is probably closer to 20 percent of the population as no virus seems to ever affect much more than that...
**a nice project for someone who's concerned about possible under-counting of deaths and with time on their hands would be to compare the weekly or monthly death rates from 2018 and 2019 with this year to see if there's anything out of the ordinary
