A properly worn three-ply surgical mask may help block transmission of large-particle microorganisms from droplets, sprays, splatters, and splashes. The mask may also reduce the likelihood ofhand-to-face contact.
The surgical mask’s three-ply layers work as follows:
- 外层排斥水,血液和其他体液。
- The middle layerfilters certain pathogens.
- The inner layer吸收呼出空气的水分和汗水。
However, the edges of surgical masks don’t form a tight seal around your nose or mouth. Therefore, they can’t filter out small airborne particles such as those transmitted by coughing or sneezing.

A recent2019年随机临床试验published in the journal JAMA supported these findings.
如果您有呼吸疾病,最大限度地减少传输的最佳方式是避免别人。如果您想避免承包病毒,同样适用。
