The #Covid_19 mortality thus far is quite puzzling in China ~ 4%; Italy ~ 8%; Spain ~ 5%; France ~ 3.5%. Then there is South Korea ~ 1.15%, Switzerland ~ 0.9% & Germany ~ 0.3%.. US thus far ~ 1.4%. Lots of theories but nothing convincing to explain why Italy
and Germany 
Hyper aggressive testing affects numerator more by driving down R0 and allowing effective containment and quarantine. Not sure what Germany is doing- probably age related blip, might help to have lesser that believes in science.
