I did hear very early on, I no longer know if this is true, that the Germans had a very different accounting system.
If a person who died with only symptoms of CoVid and tested positive they were classed that they had died of CoVid, but if the patient died of something else , say a progression of cancer or heart disease, even if they tested positive they were not ascribed to a CoVid death, even if an "opportunist" infection of the virus may have sped that death up.
But early detection and treatment would certainly be beneficial, and would provide a must better recovery . Germany had anti-viral testing and contact tracing in very early. They also have a different national character and a different leadership than we do. They get things done. All together they were better prepared.
They also have a drug manufacturing and diagnostic assay production centres in Germany. The two I worked with were in Lubeck and Leipzig/Dresden both of them would have easily been turned over to population testing within days.
