There was no talk of a 14-day quarantine for infected students, their neighbors or even entire classes, and that in tens of thousands of cases.

High and holy, but still with a back door, the ministers of education had promised children, adolescents and their parents long before the start of the summer holidays that the schools should remain open in (almost) every case in the second Corona autumn.

The nationwide vaccination of at least 12 to 17-year-olds and the immunization of all teachers should make schools safe from Corona.

In addition, air filters were promised in all classrooms.

But the delta variant of the virus and the STIKO's non-recommendation for a general vaccination in this age group for weeks made this beautiful plan burst.

Sophisticated quarantine rules that differed from country to country and were difficult to understand for the increasingly frequent case of infected schoolchildren were the emergency plan.

The fact that the health ministers have now spoken out in favor of more uniform, simpler quarantine rules may close a perceived justice gap between Konstanz and Rostock. However, many questions remain unanswered and unanswered in the details. It is up to the respective health authorities how big or small a group of students affected by Corona is that is sent into quarantine. Reliable everyday school life and lessons look different.
