One needs to be careful with such statistics though. The Netherlands had similar numbers but luckily also reported they could only trace 20% of the outbreaks. And that puts things in a very different perspective. Of the traced outbreaks, most were in schools. But that is not really a surprise, as outbreaks in schools are really easy to trace. If you have a group of 25 students which basically spend 40 hours a week together and they all get sick, super obvious. But how do you trace clients of a restaurant back to a restaurant? You mostly don't. My reading of these lists is as a mix between places that are easy to trace, and places where really a lot of infections are happening. It is hard to tell which are which and which are both. Not to mention where the other missing 80% of cases came from.
