It is like nothing changed .... since he wrote that in April 2020.
While better health is questionable in China, major comorbidities in the US w.r.t. Covid are significantly more severe, most of all way higher obesity. The expectation is the US would have higher death rates for all age groups with the exception of health care capacity, but that works in the US not most of the world.
His absolute position was based on very little information and even if we went that route, odds are it would have rapidly changed. The first wave was all old people. In subsequent waves, the hospitals filled with younger and younger people, in the US, the comorbidity of obesity a major issue. Then Delta of course happened and that changed the R0 value by a huge amount.
No doubt there were better ways to address the pandemic, but the good doctor wrote that based on exceptionally small amounts of information. Those that point to Sweden, not that their urbanization is way lower, their transit way less crowded, they have less ethnic large family groups in cities, etc. etc.
It would be nice if even one of you could use your own head and do a critical analysis before posting.
