6 Feet Distance May Not Be Enough To Prevent Virus Spread Indoors: Study

The researchers examined three factors: the amount and rate of air ventilated through a space, the indoor airflow pattern associated with different ventilation strategies and the aerosol emission mode of breathing versus talking.
Physical distancing of two metres - about six and a half feet - may not be enough to sufficiently prevent transmission of virus-carrying airborne aerosols indoors, according to a study.
The results, published in the journal Sustainable Cities and Society, suggest that physical distance alone is not enough to prevent human exposure to exhaled aerosols and should be implemented with other control strategies such as masking and adequate ventilation.
The researchers examined three factors: the amount and rate of air ventilated through a space, the indoor airflow pattern associated with different ventilation strategies and the aerosol emission mode of breathing versus talking.
They also compared transport of tracer gas, typically employed to test leaks in air-tight systems, and human respiratory aerosols ranging in size from one to 10 micrometers.
