Italy has a very old and sick population. More of their seniors are already on life support with several other diseases. I would expect less developed countries with poorer access to healthcare to have fewer very vulnerable individuals. Side note: when at the time of death you have 4 or more illnesses, and one of them is CV, on what basis is the cause of death attributed to just a single condition? It seems Russia has taken a different stance to the West in this regard but it's not clear to me which is correct. It doesn't seem ideal to ignore co morbidities.
