Random political dig aside (by the magazine interviewer mind you), the doctor mentioned ECMO machine in treatment of critical patients. This is not the first time it has come up in this thread. Reading other sources, this is an extremely rare and expensive machine, not even available in many hospitals in developed countries.
It seems like certain kinds of medical care and attention can greatly affect outcome even without an effective drug. Wuhan's initial heavy toll seems to stem from initial shortages of gear, overcrowded hospitals, and overworked staff. We can see the repeat situation occurring in Italy (caught unprepared) and Iran (totally short of gear due to sanctions). Meanwhile South Korea and Singapore which have had a large number of cases, but not too many deaths.
As I am in Canada, we are hearing a lot from Dr. Bruce Aylward who was the head of the WHO fact finding mission to China. He was very impressed with the handling of the situation and has stayed out of the politics as far as I have seen.
I think one problem with the current handling of the situation in many countries is treating as a political issue. A lot of media/countries were pointing to the infection and death of Dr. Li as a weakness of the PRC and "proof" of covering up. By creating this miasma around the situation, they gave many people a false sense of security ("I don't have to worry as long as I avoid China", "Every other country would have let doctors solve the problem"). Honestly, how many garbage articles were written about eating bats/mice/pangolins/whatever in the first few weeks of the outbreak?
