An adviser to Italy's minister of health, Professor Walter Ricciardi, said the coronavirus death rate in Italy may be higher than in other countries not only because of demographics -- Italy has the second oldest population in the world -- but also because of the way Italy records deaths of those who have tested positive for the coronavirus. "The way in which we code deaths in our country is very generous in the sense that all the people who die in hospitals with the coronavirus are deemed to be dying of the coronavirus," (https://townhall.com/tipsheet/bronsonstocking/2020/03/21/so-thats-why-italys-coronavirus-death-rate-is-so-high-n2565445)
The same is said of the flu:
In 2001, 257 American death certificates listed the flu as cause of death. Albeit, only 18 of these 257 people were positively confirmed as having a true flu, while the remaining 239 were simply assumed to have died from the flu.
