COVID-19: why do asians wear masks?

Question

Repost from Hong Kong groups on FB.

(Personal note: Even though it's probably too late to gather masks as it is almost guaranteed you won't be able to find one in your pharmacy / Chemist Warehouse or Bunnings, as that has been flying off the shelves since early mid JAN to be hoarded or shipped back to China and HK, worse than TP. I still find it abhorrent from an infection control perspective to have officials telling us NOT to wear masks as an excuse to cover up their lack of preparedness over 3 months to secure supplies and local production for the population and still allowed export to countries - when South Korea and Japan has put a stop to daigou bulk purchases. Not to mention replicating procedures from those countries that done very well to keeping a lid on it at a rapid pace. Remember: we (nurses) wear masks not just to protect spreading our bugs/virus to others, but to protect ourselves and other patients from the bugs/viruses that the infected patient has - although with the extremely tight controls of PPE and mask distribution with health services currently, I fear mass spread in the hospital system from Asymptomatic patients.)

COVID-19: why do asian wear masks?

It is very disheartening to see that history time and time again just repeats itself.

Two months ago when the COVID-19 outbreak in wuhan and other province of China became out of control, asian countries who have had experience of SARS, decided not to follow WHO’s advice (because they have repeatedly failed us during the SARS period and obviously during the COVID-19 outbreak).

Hong Kong and Taiwan, having extensive connection and interaction with China, managed to contain the virus simply because we have learned our lesson in 2003, lesson learned from the loss of hundreds of people and healthcare professionals.

We decided to wear mask despite being condescendingly laughed at, aggressively assaulted in western countries, labeled as uneducated hysterical panicky individuals. We decided to shut down schools, non essential government and medical services as well as unnecessary social interaction and gathering when it was only the beginning of the spread.

Yes, we did all these because we value the lives of our citizens and healthcare professionals. Because we don’t want to let what happened in 2003 happen again in 2020, only that this time we actually have the upper hand to prevent this with our experience from SARS.

But guess what, we were THE ONLY ONE applying what we learned from history. It’s not uncommon to see the following arguments from western countries:

1. You do not need to wear a mask if you are not sick

-> I do not know how many times I must reiterate this until someone apply some logical reasoning.

A. ASYMPTOMATIC carriers exist.

B. Definition of sick varies among individuals. People go to work and school all the time even when they are down with influenza. When have you ever seen someone (excluding Asians) wearing a mask to see GP when they exhibit URTI symptoms in Australia?

C. Risk appraisal varies among individuals. Some people are very risk averse and prefer to wear a mask if they believe they MAY BE sick, there’s nothing wrong with that. It’s a responsible and informed decision for one to make, not for random stranger to judge.

2. You only need to wash hands and do good personal hygiene, mask is unnecessary

-> of course one can only do ONE THING at a time huh?

A. Proper surgical mask has been SHOWN to be EFFECTIVE against DROPLET transmission pathogens, which COVID-19 is primarily transmitted through. There are multiple studies published during and after the SARS period by Hong Kong and Taiwan scholars.

B. It’s the same as saying if you diet, you don’t need exercise to lose weight. No one says good hand hygiene is unimportant, but why can’t you wash your hands and wear a mask? Why must these two things be mutually exclusive.

C. A mask is not expensive nor is it a nuclear weapon. Stop discriminating people wearing mask.

3. Improper use of mask does not provide protection but increased risk of infection

-> I AGREE completely. So please EDUCATE the public how to wear a mask, not tell the public not to wear a mask

A. Improper use of condom pose infection risk, should we just tell the public not to wear one? For heaven’s sake, teach them how to put it on!

B. There are many videos on YouTube with detailed explanation on how to wear and dispose a mask.

There are many more arguments like this, but if you apply logic and do your very own literature review, plus obviously empirical evidence now that almost all asian countries successfully contained the virus, may be you can finally appreciate why we wear mask.

It is a responsible act to protect yourself and your family and friends.

If there is ONE message to take away from all this: Learn from the people that HAVE went though similar scenarios in the past and understand WHY they have done what they have done. If only countries learned the lessons from SARS, we would not be in this position today.

I honestly watched and did what the Chinese did..no joke..it was like (metaphorically speaking) watching the animals running away from a forest fire when I smelled the smoke but couldn’t see the flames. I followed their lead.

I agree completely. Is it even possible for the average Australian to get appropriate masks now though?

dangoistOP•

Yes, but you need to vigilant in seeing when pharmacies and Bunnings still have stock (have a network of friends to scout and buy for you and they are discovered. )

Remember, mask (N95 or surgical, industrial or medical) is still better than none. Even cloth masks is better than none. It's all about lowering the odds of getting it.

Use them when visiting highly vulnerable people or very dense areas.

If people are not used to wearing a mask, or the mask is bad fitting and causes someone to repeatedly touch there face it is worse than no mask.

Correct, as per original post. Learn how to wear it properly, plenty of videos on YouTube these days.

Just watch the masks you are buying. In the dental industry, unfortunately, there’s been reports of others going through their bins for masks. No idea if they were for personal use or not. Try to buy sealed packets and if they look like they’ve been used, they may well have been.

Mitigation Strategy: (plan A) Avoid hazard completely => (plan B) Remove the hazard completely => (plan C) Wear PPE

Well for those that survive in the countries that are experiencing the pandemic for the first time (i.e. those did not get affected by SARS), I hope they will learn something valuable out of this hell and protect themselves and future generations if another pandemic happens again.

There should be a tiered approach to mask use and allocation. The researches from SARS show that surgical masks are about 68% effective in reducing getting infected. Hand washing 45-55%. Unvalved cloth mask has no equivalent data but my estimation is that it's about half that of surgical masks.

The main value of surgical and unvalved cloth mask is that it protects the world from the wearer. Asymptomatic carriers will be less infectious. If everyone wears one regardless, it cuts down the transmission; this is especially important on buses, public transports, and planes. If you are healthy, put on an unvalved cloth mask and have several so you can rotate, just like your underwear (if you are one of those who don't change underwear everyday, you are disgusting). Prioritize surgical masks for symptomatically sick people and their carers.

Valved cloth masks are slightly more effective, about 70% that of surgical masks. You still need to wash and rotate.

N95 masks are really effective, like 91%. Reserve this for people who are in greatest danger: healthcare workers.

Mission-critical business and workers: like water, food, electricity, and transports need to invest modestly in reusable elastomeric respirators. These are not expensive. 100 dollars will buy you a respirator and particulate filters sufficent for at least 6 months (depending on the level of pollution). These respirators have a shelf life of 20 years and the filters have a shelf-life of 5 years (if you buy 3M stocks) or 10-20 years (RD 40 filters). Do not rely on disposable masks. People make excuses like "I can't breath through a light disposable N95, I certainly cannot breath through a respirator". No. I've worn several. True, N95 masks becomes difficult to breath through after a while but I've worn elastomeric respirators for 4 hours continuously without any issues.

I recently argued with a manager in a metal working firm and she said that her firm ran out of N95 masks to give to workers but "work still need to be done", so "everyone" agreed that workers should be given cloth masks. I was fucking livid. They did not prepare for this, so now someone is paying the price; not the twat I was arguing with, she's safe in the office. I pointed out that you can still purchase some respirators and give workers adequate protection. Nope.

I wonder if you'd mind explaining the difference between a surgical mask, unvalved cloth mask & valved cloth mask? Thanks

This is the research on their relative efficacy https://www.nature.com/articles/jes201642

For 100nm particles , which is close to the virus, N95 mask blocks about 90%. Surgical mask isn't bad, at 70%. Vavled cloth mask is actually not far from 90%. Unvalved cloth mask is at 30%.

surgical mask example, unvalved cloth mask example , valved cloth mask

Surgical mask has three layers: outer layer with fluid resistance and inner resistant layer. Cloth mask is usually just 3 layers of cotton. Valved version has a one-way exhalation valve.

THIS!! This is how to keep a lid on things.

Textbook is theoretical knowledge, it is the experience that triumphs.

Because there are not enough masks. But, anything is better than nothing, even a scarf. Here is how to go close to the effectiveness of a proper mask: https://www.youtube.com/watch?v=aNjpH5lBZ8w&list=PLb0pTwlVfukmdMWEnWHoNTW1h4lbsCIyl&index=2&t=0s

Could not agree more. After living in an Asian country (Japan) wearing a mask when sick, or when allergens are bad, became "normal" behaviour to me, and as responsible as covering your mouth when coughing or sneezing. I read the research coming out of HK and Taiwan, the stats on surgical and even DIY masks, and examined the rates of spread in countries that have high rates of mask use vs. not. On this basis, I've recommended masks to family members, and been wearing one myself when social distancing isn't an option, despite all the misinformation circulating (and weird looks). As I posted in another subreddit, earlier on in the crisis, I was at a sparsely populated airport in Australia where I was able to practice social distancing, but planned to don a mask just before boarding, reasoning my risk would be higher (of spreading or contracting) in the plane itself. After witnessing the rude stares and snarky comments those wearing masks inside the airport received, I almost chickened out. The social pressure to shrug and say "she'll be right" in Australia is very strong. But then I looked closer at who was wearing masks. Passengers of Asian appearance, for whom wearing masks might be considered more normal, responsible behaviour. And elderly passengers. Wearing masks isn't just about protecting ourselves. It's about protecting the most vulnerable in our society too. OP's analogy to condoms is exactly right. Just because something isn't 100% effective, or because people don't always get it right, doesn't mean it's not immensely helpful. Even cutting risk of aerosol droplet transmission by half would be immensely helpful in smoothing the curve and taking the burden off our health system. But in order to do that, just like immunisation, we need a herd response. The only reason I can think of to discourage the general population from wearing masks when we know there are asymptomatic carriers and when we know they're effective at reducing transmission is to prevent panic-buying, stock-piling, hoarding and price-gouging that might leave healthcare professionals with a shortage. But that's no reason for people who aren't symptomatic not to use DIY masks, and leave the commercially produced ones for doctors, nurses and confirmed cases. (For those interested, here's some instructions for masks from Hong Kong-Shenzen Uni: https://www.scmp.com/news/hong-kong/health-environment/article/3050689/how-make-your-own-mask-hong-kong-scientists)

You also can go to China too since you are keen to exploit others for profit, just like the communists...

In fact you probably will welcomed with open arms and a free membership to the CCP for helping out with the motherland and the party.
