我o係一個台灣網站抄出黎o既一段文字：
「既然我們無法跟所有人保持二公尺以上的安全距離，那麼我們是不是可以把病人的口鼻封起來，這樣含有病毒的飛沫就會出不來？我們是不是也可以把自己的口鼻封起來，這樣含有病毒的飛沫就進不來？但是我們一般所用的口罩，防護的效果並不好。這些口罩可以檔掉大體積的顆粒，但是無法檔掉很多更小的飛沫顆粒。曾經有人在帶了口罩以後，用力打噴嚏，然後在極快速的快門條件下，用照相機把打噴嚏的情景拍攝下來。洗出來的照片顯示，很多小小的飛沫的確可以穿透一般的口罩。」

Author: 人一個 [ Edit \| View ]	Date Posted: 13:36:35 04/18/03 Fri 根據教育o既指引，教職員及學生須戴上自備口罩，但唔係個個學生都會自備口罩，咁樣學校就要幫佢地準備喇。所以學校準備口罩，係因為戴口罩有用，定係因為教育署話要戴口罩，就真係唔知喇。
