Why is the coronavirus mortality rate so much lower in Germany?

The Spectator
Is there something about being Germany which protects the body against coronavirus Covid-19? Probably not, I would guess. In which case why do the latest figures from the Robert Koch Institute show that the country has a case fatality rate (CFR) of 0.3 per cent, while the World Health Organisation (WHO) figures from Italy seem to show a CFR of 9 per cent? To say there is a vast gulf between those figures is an understatement. If nine per cent of people who catch Covid-19 are going to die from it we are facing a calamity beyond parallel in the modern world. If only 0.3 per cent of people who catch it die from it, this pandemic may yet turn out to be no worse than seasonal flu, which as I have explained here before is estimated by the US Centers for Disease Control to kill between 291,000 and 646,000 people a year without the world really noticing. According to John Hopkins University, which is collating fatalities data, 15,308 have died to date.  .....On the other hand, German hospitals do not routinely test for the presence of coronavirus in patients who are dying or who have died of other diseases. Italy, by contrast, is performing posthumous coronavirus tests on patients whose deaths might otherwise have been attributed to other causes. This matters hugely to the Case Fatality Rate for each country. As explained here before, CFR is not to be confused with the genuine Mortality Rate."
