Conserving Supply of Personal Protective EquipmentA Call

The same logic would permit a washable cloth mask to cover a surgical mask, permitting the surgical mask to be used many days. The owner of each surgical mask could UV disinfect it by laying it in direct sunlight for a few hours on each side. Someone with a sewing machine could make 30 masks a day, so 500 community volunteers could produce
