Today I came up with an idea to use existing data in a new way, and I'll start with my findings right away:
European countries are NOT detecting the vast majority of cases. The actual amount of cases in Europe is likely 3 to 7 times higher. I'll explain:
1) Confirmed cases (=people with #COVID19) / people on intensive care
2) People on intensive care with COVID / people who died due to COVID
3) Confirmed cases / COVID deaths
It's much harder however to detect all mild #COVID19 cases.
This too implies the reported # of deaths and ICU are more likely to be correct than the # of cases.
They test A LOT. They have drive in screening centers where you get diagnosed without leaving your car and get the result by text message.
