Ventilation is a very important factor in lowering the risk of the spread of Covid-19 indoors. Whenever possible in public buildings such as workplaces and classrooms, it’s essential to ensure good ventilation with fresh air.
Would it be possible to study how building layout can impact the flow of viral aerosols? Thus in future we could design buildings with natural ventilation that could minimise the harm caused by virus aerosol. Maybe just different workplace layouts could radically reduce spread.
