“May be they just don not want to know?”
Or maybe they are just not at the same point in a wave as UK is (yet). Maybe they don’t have as many people requesting testing. The previous waves in different countries didn’t all happen at the same time. As far as I can tell, from informaton on https://ourworldindata.org/coronavirus, Germany and UK count tests performed. A more useful figure would be persons tested (and sepearate episodes). If someone has a lateral flow test that shows positive then subsequently has a confirmatory PCR test, that is one test to me not two. Also, some testing for those self isolating requires more than one test at different time periods. If they are on the same person in the same episode then really should count as one test.
@Mods
I have posted the link to ourworldindata because it allows you to compare different countries by selection for various data which is very useful when looking at timelines. I have specifically tried to show Michael that although the UK is showing high rates of cases and Germany low it doesn’t mean that at some point that position will be reversed.
