Apples to oranges. Can not compare Italy with Germany.
Germans are willingly being tested, there process, order, proactive testing. In Italy everyone is 1) quarantined for the past 2 weeks and 2) didn’t even give a crap about this prior to the quarantine.
Italy is triaging, out of hospital space, vastly over estimating numbers, and probably using models with some accuracy to report their numbers. Unless someone can PROVE this otherwise.
Their death rate is what it is due to a very elderly population, with 2 or more co-morbidities, in understaffed and overwhelmed hospitals full of chaos, and infection.
