1/n A long time ago, in a galaxy far, far away, I was asked this question by @lucaxx85, on comparing Switzerland to Sweden, re #COVID19. https://twitter.com/lucaxx85/status/1274937757484318720

2/n So let's look first at outcome differences between Switzerland and Sweden, before we get onto the whys. "Daily new confirmed #COVID19 cases" is striking; note how the pandemic hit Switzerland before Sweden.

3/n Cumulative confirmed #COVID19 cases, #Switzerland and #Sweden, reinforces how the pandemic hit the Swiss first. It would be near 2 months from start of pandemic in Switzerland before Sweden equaled it in cases. Officially. But the Swiss got it under control.

4/ Daily confirmed #COVID19 deaths, 3-day av, #Switzerland & #Sweden, suggests a different story. It suggests to me the pandemic started earlier in Sweden than thought, only the Swedes couldn't be bothered testing. Also, it suggests the Swiss acted *very* quickly.

5/n Cumulative confirmed #COVID19 deaths, #Switzerland & #Sweden, to me confirms my suspicions in (4) above. Instead of looking like the pandemic hit Sweden 2 months later, looks like the Swedes simply. didn't. test. or. diagnose. or. protect. much. at. all..

6/n And now, finally, @lucaxx85, we get to the whys. Because this looks to me like Switzerland DID undertake much more rigorous measures than Sweden did, and very early at that.
