Schools are busy places: lots of children and teachers are constantly moving around in classrooms, corridors and break areas. Contact surfaces such as door handles, light switches, window handles and tabletops are touched by many different people. Each individual can potentially transmit infection. This is why hygiene in schools is so important. The aim is to ensure the health of children, teaching staff and parents, and prevent the transmission of infectious illnesses – not just since SARS-COV-2 and the coronavirus crisis.
