This is not only a matter of teaching material, but also impacts the social skills that children and young adults learn imparts through the interaction in school. At the beginning of the COVID-19 crisis, it was said that schools would certainly not be closed, but in the course of the epidemic, attendance was interrupted. Unaware of the role children play in the dissemination of COVID-19, the schools have now been reopened. It remains to be seen how quickly a return to school normality will be possible.
