Study of the low moving efficiency of bioaerosol with insufficie<i>nt air inflow and exhaust in the public toilets</i>

Due to insufficient ventilation, public toilets have become incubators for cross-infection during the pandemic. WHO has proposed an approach improve indoor including ventilation in isolated spaces like toilets, by applying 10L/s/person criteria, and keeping fans running effective ventilation. However, less air inflow many causes We ever found colony forming units (CFUs) staying surrounding floor junctures, inside of a lid-less trash can toilet. If minimal exhaust is not equal inlet air, bioaerosol will stay toilets. Therefore, speed suggested be somewhat higher reach 0.5m/s or more facilitate reduce risk cross-infection.
