COVID-19: Schools urgently need guidelines on improving ventilation in classrooms

There is an urgent need for guidelines on how schools can use ventilation to reduce the risk of COVID-19 transmission in the classroom, according to doctors at Imperial College London and the headteacher of a secondary school in Pinner, Middlesex. In a commentary published by the Journal of the Royal Society of Medicine, the authors say that improving air quality in classroom spaces should be as important as following government advice regarding social distancing, mask-wearing and hand washing.
