She states it as diminishing the viral load in the air in a healthcare setting. It would do the same out of a health care setting.
In a healthcare setting, they deal with patients who are critically ill with fulminant infections, and the virus is aerosolized in conditions where they suction the airway, and do endotracheal intubations and extubations. The viral load is WAY different with these patients compared to people in public. And the aerosolized conditions described above are certainly different than the conditions you’d encounter in public. These are conditions unique to caring for critically ill infected patients in the healthcare setting, and are NOT the same as those outside of the healthcare setting.
