One study from the Centers for Disease Control and Prevention found that a surgical mask protected the wearer from about 7.5 per cent of the particles generated by a simulated cough. But knotting the loops and tucking in the sides of the medical mask reduced exposure by nearly 65 per cent. Covering the surgical mask with a cloth mask, a technique known as double masking, reduced exposure to the simulated cough particles by 83 per cent. A Virginia Tech study looked at how well homemade masks, surgical masks and face shields protected the wearer, based on particle size. The research showed that most masks could block very large particles, like those from a sneeze. But when the researchers looked at smaller aerosol particles that are hardest to block, protection ranged from near zero with a face shield to about 30 per cent protection with a surgical mask. Based on the findings, Dr Marr and her colleagues concluded that a two-layer cloth mask made of flexible, tightly-woven fabric, combined with a filter material(like a coffee filter or surgical mask), could offer good protection, reducing 70 per cent of the most penetrating particles and trapping 90 per cent or more of the larger particles. A study from Tokyo tested how well different types of masks protected the wearer from actual coronavirus particles. It showed that even a simple cotton mask offered some protection(17 to 27 per cent). (Words 235) Typing Passage 2📌📌
