No, you're not understanding how it works. You've got it wrong on a few levels:But you said
"I can't see anything suggesting it's as low as 0.5%.
There probably aren't fewer that 100 cases in the UK."
If there are more than 100 cases in the UK and the only Brit to die was on a cruise ship in Japan then the UK death rate is lower than 0.5%.
1) The number of reported cases in the UK is 87 or so at the moment. It seems obvious that over 100 people have it, as some will not have had symptoms or been tested yet. But you're trying to count those who haven't even had symptoms yet, as people who will definitely survive the virus. That's ridiculous.
2) We weren't talking about UK death rate, we were talking about worldwide death rate. I don't think you specified UK only.
3) The numbers in the UK are currently too low to be considered a proper sample size.
You can't say that 1 person in Wales had it, they didn't die, therefore the death rate in Wales will remain at zero.
I asked where you got the figures. You're saying the BBC. That doesn't mean I'm arguing with the BBC. The BBC didn't write that we can use the UK cases to predict a future death rate.Still. as pointed out a number of times on this thread, the numbers I got were from a BBC factual special on covid-19 and applied a statistical margin of error to the WHO data at that time. So, you're not arguing with me, you're arguing with the actual advice that's going out from the national broadcaster.
