Performance of Fabrics for Home-Made Masks against the Spread of COVID-19 through Droplets: A Quantitative Mechanistic Study
Ayden et al. compared the performance of 11 common household fabrics at blocking large, high-velocity droplets using a commercial medical mask as a benchmark and found that while most fabrics have substantial blocking efficiency, two layers of highly permeable fabric can achieve >94% efficiency compared to medical mask by reducing the velocity of transmitted droplets…

A Modelling Framework to Assess the Likely Effectiveness of Facemasks in Combination with ‘Lock-down’ in Managing the COVID-19 Pandemic
Stutt et al. report modeling results that show that when facemasks are used universally, Re can be reduced below one without the use of further mandated lockdowns or other non-pharmaceutical interventions. They conclude that lockdowns in combination with universal facemask use could substantially reduce Re and prevent subsequent waves of disease transmission. Stutt et al….
