Intensive ventilation of the classrooms is an important element in the schools' hygiene concepts for protection against corona. Many students and parents fear that it could get cold in the classrooms in the coming weeks and months. Every 20 minutes, the Ministry of Education stipulates that classrooms must be ventilated. This is a measure to ensure that the aerosol concentration and thus the risk of corona does not increase too much. Photo: Guido Kirchner/dpa - 20201026_PD1179 - Rechteinfo: Rights Managed (RM)
