咪一路以黎講緊既野囉
戴口罩要配合洗手同唔好鳩摸
你戴口罩但又係咁撚個口罩然後又捽眼，返屋企又唔洗手係無撚用
啲鬼佬呢個時候永遠分化撚上身，口戴同hand hygiene明明可以同時做，但就要講到戴口罩就咩都唔做得

內容係戴口罩 原來係對"防疫"無撚用
除非你有醫學知識咁戴n95級別以上/豬咀
最有用係洗手 保持hand hygiene
Disposable medical masks (also known as surgical masks) are loose-fitting devices that were designed to be worn by medical personnel to protect accidental contamination of patient wounds, and to protect the wearer against splashes or sprays of bodily fluids (36). There is limited evidence for their effectiveness in preventing influenza virus transmission either when worn by the infected person for source control or when worn by uninfected persons to reduce exposure. Our systematic review found no significant effect of face masks on transmission of laboratory-confirmed influenza.
