it addressed specific measures that the Chinese took to slow the infection and reduce mortality.
1. Imposed a quarantine on a metropolitan area of 11M;
2. Mass scale up - medical personnel and equipment (ventilators and respirators). They dedicated whole hospital wings as dirty wards. They built 2 hospitals in a week.
3. They instituted mass testing everywhere. They discovered most infections were occurring in the family unit with prolonged contact. So if you went to a store or building, there were fever teams to take your temp. If you had a temp then you had to get tested and were not permitted to return home.
4. They put Covid-19 patients on ventilators and respirators early on and they also used extracorporeal oxygenation to reduce the mortality rate.
Simply stated Trump's dilly dallying has closed off a lot of opportunities to mitigate Covid-19's effects both as a public health threat and as an economic disaster.
