At least , shared responsibility. Already informed the general public but how to get the masks, they are on their own. Can be a big market to HK production, that's why more than ten companies get involved. Besides, reusable masks are getting popular, the one from Canada is pretty good, with viral protection and replaceable filter. Won't compete with medical staff.

我覺得其中一個重要原因, 就係佢地極度唔夠口罩, 政府出聲叫人戴但市場沒有貨, 都唔會有好結果.

老美一路叫人唔駛（好）戴口罩，昨天卒之改口，要求在公共地方要戴上非醫療級口罩！
之前叫人唔駛係因為醫護人員都唔夠口罩，睇過有報導話有醫院要求一個N95要用一星期，驚一話戴口罩，情況會更差.但確診數字而家直線上升，卒之要改口！

Must have aerosol transmission based on previous cases, also explaining why the virus is so contagious . I didn't believe level one mask can fully protect oneself, already mentioned about this last two months. Implied on footage, not even N95.
..

唔戴口罩搭巴士/黨鐵會比人打！所以一定要戴！

感染者呼出氣體應該有, 問題係病毒數量夠唔夠令其他人感染~

Good information yet people can still insist, not A/B comparisons for the sake of argument. HK is warmer and humid, less favorable to the virus.(I believe this is one of the co-factors) So, let them don't wear mask but the virus would come back as 3rd wave.

good explanation on airborne vs droplet transmission... I think I need to get goggles just to be safe as well....

有帶同無帶口罩一睇圖就知道係...當然有分別.

Many things in everyday life, you can't prove, similar for mask can protect Vs bacteria or virus in the street due to no scientific study on a batch of people, so many variables. In fact, just believe in the design and application, plus kind of observation. (even the no. of flu/cold patients was reduced) Similarly, some guys still insist that there was no proof re. lung cancer for a particular patient was due to smoking, though smoking might cause lung cancer.

People love to challenge, instead of looking for a viable solution, for the benefit of many others. Even you can provide strong evidences, they would still think in the same way, yet attacking your points one by one.

我根本吾會信CHO所說的一切

我不相信 WHO 這說法!

Loong but fig 2 is interesting. 100/10 um.

Human breath,too. Must be in a closed environment, for hours/days. See the cruise ship incident.
