The biggest problem with the discussions on most subject is that everyone cherrypicks their data or just don't have whole picture. And this picture is a realy big one.

For example Sweden already had a big spread because of the big traveling weeks of school holidays. People tend to cluster together in certain areas from different countries. The Finish people goes to this location in the alps, the Norwegians to this other, and the Swedes to this third place. Turns out the third place had a superspreader in the pub. Mystery solved?
