Four basic categories of interventions to reduce the spread of SARS-CoV-2 that can result in a significant reduction in the risk of SARS-CoV-2 airborne transmission. Source control: Source control can significantly reduce, if not completely eliminate, the number of aerosols released into the air. Filtration/Ventilation: With effective filtration/ventilation, the number of viral aerosols can be greatly reduced. Individual protective equipment and social distance: These interventions can offer some protection by reducing a person's exposure. Hygiene: Research indicates that the highest viral loads or positive samples can be found on the floor. Cleaning the floor can reduce the possibility of resuspension.
