@epythymy The re-opening of schools has been going very well so far. The cantons were left to each decide how to handle it (as is usual here), and for mine they have full school days, full classes and no social distancing required for the children. The teachers are advised to maintain the 2m distance, and when they can't they should wear masks. There is also a lot of hand washing during the day (parents should provide hand cream now, as well as sun cream!).
There was a LOT of debate about this, with people saying that it was inadequate and they would keep their children at home, but in the end it's been fine. There has been no increase in cases, that has come down nationally - I think the figures for the past five days have been - new cases - 20, 19, 3, 9, 17 and new deaths - 0, 1, 0, 0. There have been 2 new cases in my canton in the past week - 2 siblings of school age - their classes were sent home for 14 days, but the school did not close - and there have been no other cases reported from their classmates, teachers or parents.
Testing is widely available and anyone who suspects they might have symptoms is encouraged to go and be tested.
Its probably still a bit early to know for sure, but it's promising.
