All affected school classes in the cycles 1, 3 and 4 will be tested for the virus by mobile test teams.
A total of 24 classes in Steinsel have been in quarantine since Wednesday, after eight teachers and two children tested positive. The maison relais, too, has been closed.
Only cycle 2 is currently working as normal. Minister for Education Claude Meisch confirmed to RTL on Thursday that the entire school will be fully tested twice.
