Coronavirus - What Happened?

Depends on the country and demographics, like you said, I guess. I wrote the following in another thread after having followed Singapore’s stats for several months, which are very concise and accurate if you visit their government’s website, and wrote this:

98-99% were Bangladeshi migrant workers 20s to 40s. So all relatively healthy, non-smokers, got lots of exercise etc. ALL workers were tested according to credible sources.

That’s like a 0.04% death rate.
