The winter break in europe is very strong correlate to the size of the outbreak peak.
Norway,Denmark,Finland,Germany all with excellent low peaks had their holliday before week 9
France,Belgium,GB,Sweden,Netherlands all had their winter holliday partly or fully week 9 or 10
See the trend!
Finally GB has the same problem as Sweden with a slow downward slope after the peak and if Sweden is 2,5 times as bad as Denmark, GB is about 2,0 times as bad as Denmark whenit comes to the behavior after the peak. So it does not look like it's because of the lock down, more due to the fact that we had a critical mass of people that transmitted the virus so that new clusters continously crop up and delay the recovery. If you look at the media around Sweden, the next time around we will have close down italian style and punish all good people that followed the rule. This is like putting another sticker to a tire ontop of an old one to really make it hold although the tire is leaking elsewhere in a new hole.
