Since underlying conditions have an impact on death rates, I just did a quick search and found out 36.5% of US adults are obese, while only 4% of South Korean adults are obese. Coincidence?
You need to break those numbers out by age groups. You need to provide sources for your data. You need to provide percentages of those who died who are obese. Percent of US infected vs percent of Korea infected (stage of disease). Likelihood of further spread in Korea vs US. And any other factors that might come into play. I’m interested, but I’m not going to do the research for you, other than to say I used your numbers and back of the napkin calculations with 100% of those dying being obese, still need six times the number in Korea to die just to equal current deaths in US based on your seriously inadequate available and unsourced information.
