It is all a question of the real figure. Suppose Covid-19 kills 1% of those infected. Assume 11 days pass from the positive test to death. Then we have to compare the current number of deaths with the number of infected people 11 days ago. In Germany this is 4%. That said, Germany actually has four times more infected people than were tested.
Italy has twenty times more infected people than have been tested.
UK has forty times more infected people than have been tested.
In the United States, the number was 50 times a week ago. Now it levels off at fifteen to twenty times because testing is now much more intensive.
The problem is you don't know if the statistics from these countries are measure in the same method. I have heard that German doesn't include some of the deaths from other complications even if the patients have contracted the covid-19. There are just so many variables that we simply can't rely upon these data. One thing we can rely upon is how many people got tested and how many of them came back positives. If the sample size is large enough, we would probably know when they reach covid-19 apex.
