Respiratory droplets less than 100 microns(a lot less for another definition) can be airborne as mentioned before. (WHO document)Talking for 5 minutes is equivalent to coughing giving out 3,000 droplets. Sneezing is 50,000 droplets ranging from 0.5-12 microns. Air flow would aggravate the situation(even door slamming), footage only proves what I said. Surgical mask whatever the construction, is only tested with 3 um droplets via nebulizer, to ASTM standard. Can't see it's effective for viral protection even upon wearing.(usually no VFE test) However, I believe that concentration and contact time would also matter.

Come on, give me a big hug!

[#2] That means no matter what we do, sooner or later, we will contract the virus. So Boris Johnson could be right.

It further proves that the main purpose of encouraging people to wear masks is to prevent the sicked from spreading the virus, not that it can protect you from infection in a room full of it.

I think I have to start wearing the eye masks I bought last week.

All people will die, only a matter of when. Contract the virus only after death, can't infect a dead man, AFAIK. So, delay as far as practicable or until there is vaccination/cure.(not treatment) Or pray to ET to end this experiment when all data were collected. Same for breaking a lock, no matter how secure it is, someone can get access to your premises. Just buy more time, this is the crucial point.

Besides, the ASTM test is conducted with a bit of differential pressure. So, surgical mask can still protect a bit unless there is gusty wind blowing towards you. Flow rate is proportional to pressure.

Avoid sugar intake(or high carb diet resulting in glucose in blood), high glucose level would aggravate viral/bacterial infection.(an observation, no underlying reasons) Guys with glucose intolerance should be aware of such. (high fasting glucose, or with high A1C) Of course, having food based vitamin C and zinc supplement on daily basis. But all sold out.(so many smart guys) Just do whatever it takes. My last line of defense is Mesosilver CS solution(3x 500ml bottles) and nebulizers(got 2 from France). They are quite expensive but dead man needs no money except defraying funeral expenses.

This appears to be useful, Chloroquine, for treating malaria. A couple in the States died due to taking the different compound for cleaning aquarium, two different things. Reflecting the high cost of treatment in hospital.



https://en.wikipedia.org/wiki/Chloroquine

"It is also being studied to treat COVID-19 as of 2020.[3] It is taken by mouth.[1]. "

禾懷疑即使係呼吸近距離都有機會散播病毒唔一定要飛沫,咳嗽,打乞嗤。

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

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.

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

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.

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~
