In a study published in the Journal of the Royal Society of Medicine, the authors state that the improvement of air quality in classrooms it is just as important as government advice on social distancing, the use of personal protective equipment (masks) and hand sanitation.
The researchers referred to the case of the aviation sector: the risk of contracting the virus on a flight is currently lower than in an office building or classroom. Dr Kaveh Asanati, professor of occupational lung disease at Imperial College London’s National Heart & Lung Institute (Faculty of Medicine), and lead author of the study, said:
“The ‘tiered’ risk reduction strategy used in the aviation industry appears to have worked efficiently. The strategy includes passenger testing, the use of face shields or masks, various hygiene measures, and most importantly, maintaining clean air by the circulation of a mixture of fresh air and recycled air through HEPA filters (High-Efficiency Particulate Air) ».
