The children have been placed in quarantine and have not been allowed to return to school, according to a letter addressed to Kehlen residents by deputy mayor Félix Eischen.
The letter went on to say that the children had not contracted the virus at school.
After five days, the children will be tested once again. Should the test be negative, they would in theory be allowed to attend school again. However, this may not occur given the proximity to the summer holidays.
