If Germany is not reporting a death if a person has high blood pressure, then I think theirs are under. The death rate from numbers I had seen were like 10x more fatal if you have some other issue.
IMHO Italy is more accurate, because it could be said that the deaths would not have occurred, yet, without Covid.
Other explanation, per an email from a German relative: Germany is probably the only country in the EU where following the WHO recommendation of 1m distancing will bring people closer together'
