Exactly. I don't see how trying to limit testing to people who had contact with known cases or traveled to at risk countries (as practiced in Germany) can be successful.

Earl_of_Northesk: The RKI is conducting random sample testing to keep track of Influenza in Germany. These tests now also test on COVID-19. So far, not a single prior undetected case of COVID-19 has shown up in these samples. It is thus highly likely that the extensive early tracking and testing means that Germany has, in comparison to other countries, a very low rate of undetected cases, which would obviously lead to a lower mortality rate. That's what the President of the RKI also said in todays press conference together with Angela Merkel.
Painy_: How big is the RKIs sample size tho?
patientzero_: All cases that had the flu and went to the hospital. So the more severe once. But they also re-ran the tests from the beginning of the year to test for Covid-19. If you can't detect it in there it wasn't in the country most likely
Sounds like a massive amount of testing that no other country can match.
