Correct. I warned about this mid January on the earlier thread “two things you don’t want to hear” where there were some absolute morons thinking that “the virus won’t get us in America”.
It is correct that likely a very large % of the world, especially those in big cities globally, will be exposed.
As for the mortality rate, this is, for various reasons, hard to both measure and predict. This is because the vast majority of those infected don’t ever get tested as positive or even seek medical advice. And secondly because symptoms of infected vary hugely. From my own knowledge and sources I can tell you the rate of directly caused death to those actually infected could be around 1/10000. There are many people, especially kids, are almost entirely asymptotic (yet are fully infected and also are spreaders). For those who are infected and who are ill enough that they actually seek medical attention rate could be 1/1000. And for those who are elderly, smokers, immune compromised, already have pre-existing organ problems, rate could be as high as 4-5%.
These numbers are huge, if (as I have told you and warned) a significant number of global population get infected.
Any (non-idiot) questions let me know and I will answer. This happens to be a field where I know a significant amount and have global insights (both on the health side, geopolitical, and economic).
