claim: efficacy of face masks , neck gaiters and face shields for reducing the expulsion of simulated cough-generated aerosols
evidence_1: one of the primary benefits of face masks and other coverings is as source control devices to reduce the expulsion of respiratory aerosols during coughing, breathing, and speaking.", "our results show that face masks and neck gaiters can significantly reduce the expulsion of small respiratory aerosol particles during coughing.", "efficacy of masks and face coverings in controlling outward aerosol particle emission from expiratory activities.", "efficacy of face shields against cough aerosol droplets from a cough simulator."
