It sounds like many of the deaths were people who were so sick from comorbidities that all it took is some problem from an illness for their comorbidity to cause their death. I am not sure how those should be scored, but if it were the flu their death would be scored as diabetes or heart disease or whatever the health issue was. Statistics....
Back when this all began, I remember an Italian doctor saying that 95% of the fatalities were so sick with other things they’d be dead within a year anyway.
