Compare that to bacteria’s 1,000-nm size. It’s a grape compared to a grapefruit. A surgical mask whose purpose is to block bacteria will do little to prevent passage of the smaller coronavirus particle. https://www.fastcompany.com/90483762/why-masks-arent-better-at-protecting-us-from-viruses Your own article agrees with me that N95 masks that I quote work well: "That’s why N95 masks, which block 95% of all airborne particles, are the gold standard in hospitals treating COVID-19 patients. They have a much more selective filter." You correctly state a coronavirus is ~.125um. What you don't mention is that these masks block 0.125um particles better than they block 0.3um particles. In fact, 0.3um particles have maximum penetration power, which is why masks are rated for 0.3um. Why? Below 0.3 um Brownian motion, collisions of fast air molecules, push small particles about so they don't fly straight and are more easily captured. So the idea a virus penetrates better because of their size is not correct. Anyway, most viruses are part of larger drops or goop. When properly worn, N95 masks and above work well to block viruses from entering the airways. IOW, Yinn is right. 1 Link to comment Share on other sites More sharing options...

You are misrepresenting what is stated in the article you presented to make your point. Doctor Anthony Fauci, whom I listen to in his daily briefs at the White House, did not say we should wear a mask as you suggested he said. That was your interpretation. This is what he said: =================================================================================================== Quote: (directly from the article you linked) “The idea of getting a much more broad, community-wide use of masks outside of the health care setting is under very active discussion at the task force. The CDC group is looking at that very carefully,” Fauci told CNN. “The thing that has inhibited that a bit is to make sure that we don’t take away the supply of masks from the health care workers who need them,” he continued. “But once we get in a situation where we have enough masks, I believe there will be some very serious consideration about more broadening this recommendation of using masks.” Fauci cautioned that while “we’re not there yet,” he said he believed the task force was “close to coming to some determination” soon on whether to expand the administration’s recommended mitigation measures to include masks. “Because if, in fact, a person who may or may not be infected wants to prevent infecting someone else, one of the best ways to do that is with a mask. So perhaps that’s the way to go,” he said, adding that the subject was “under very active consideration” and would be raised at the task force’s meeting on Tuesday afternoon. ================================================================================================= It is quite clear that the matter is still under consideration and Fauci did not say, as you said, that we "should wear masks". 1 Link to comment Share on other sites More sharing options...

Infection / 1 million population: Germany 931 Czech 337 South Korea 195 Japan 19 Taiwan 14 Thailand 27 and if you don’t trust the infection numbers due to lack of testing, how about the number of deaths per 1 million population: Germany 11 Czech 4 South Korea 3 Japan 0.5 Taiwan 0.2 Thailand 0.2 As I explain above the infection numbers are inaccurate. Germany conducts 500,000 tests a week. Therefore it finds more cases. You can't go by 'identified' case numbers, by that measure Zimbabwe is the most successful country because it identifies no cases because it doesn't test.

It is scathing about the quality of the majority of the studies which it reviews, however, then goes on to conclude that because of a slightly higher cumulative number of studies saying a mask works than ex measure therefore masks work. One does get the sense that this is not an actual but a review of many studies, many concerned with influenza not the SARS Cov2 virus. I also find it odd that it says: "A tiny study comparing the N95 respirator with paper surgical masks in volunteers found that surgical masks, even when worn in multiple layers (up to five), filtered ambient particles poorly (Derrick 2005); this principle was confirmed in another small study of air filtration to prevent droplet spread (Somogyi 2004)." But then goes on to say there is no difference between a surgical and a N95 mask in effectiveness. Still, very interesting. A surgical mask does not protect the wearer, it protects others from the wearer. So it may not be good at filtering ambient particles, it does significantly reduce the spread of particles from ones mouth to the ambient air. So if we both wear a mask, my mask protects you, and your mask protects me. Especially with viruses that are transmitted before symptoms show, it is important for everyone to wear masks. 4 2 Link to comment Share on other sites More sharing options...

It is isolating those infected. https://www.nytimes.com/reuters/2020/03/26/world/europe/26reuters-health-coronavirus-germany-tests.html Now, you don't look at a case numbers, okay, because by that measure Zimbabwe is the most successful country as it, supposedly, has zero cases. Because it does not do testing. You look at the mortality rate. Even though Germany has been testing the most, and therefore identified more cases than most, it still has the lowest mortality rate of all major countries. The only countries with lower mortality rates are mini-countries like Austria (which is Germany anyway) and Norway, they don't count. If you look at the table below you will see that where it counts, mortality rate, Germany is the leading nation of all the major countries, in fighting Covid19.

Hey boys and girls, let's specifically define what we're discussing. Are you a spreader or a spreadee of Corona? The above quote is addressed to spreadees, i.e., a healthy person with the potential for catching Corona from a spreader. And its the spreaders that the most recent CDC addresses about masks. Their worry: 25% of Corona infected folks are asymptomatic but can spread the disease with an uncovered cough or sneeze. So, maybe everyone feeling fine should wear a mask, just to preclude those 25% of feeling fine spreaders from spraying their surroundings with contaminated droplets. I suspect the reason for not yet going full tilt with this is because of the fear about adding to the mask shortage, to include the more expensive and efficient masks used by medical personnel. Anyway, this 'no need to wear a mask' argument may make sense when only the spreadees are being addressed. But, when we now know about all those spreaders walking around that feel healthy -- yeah, please do wear a mask. 2 1 Link to comment Share on other sites More sharing options...

It's fair to say that with some countries there are significant doubts about the figures. I'm not just talking about Thailand, whose figures are not worth the paper they're written on, but even the UK. "The UK's coronavirus death toll is higher than official figures show as the current statistics only include those who have died in hospital. Today, the true numbers will be revealed after the Government admitted that the 1,415 fatalities so far recorded in Britain are not the actual number. Daily figures recording the pandemic's death toll have shown a growing time lag approaching up to three weeks." https://www.dailymail.co.uk/news/article-8170065/UKs-coronavirus-death-toll-HIGHER-official-figures.html However, I would say that comparing the mortality rate figures between South Korea and Germany would be reasonable, since one can probably trust the figures for those two countries. I think you will find that, even as of today, the mortality rate of Germany is half that of South Korea. Link to comment Share on other sites More sharing options...

Mattd Posted April 2, 2020 Share Posted April 2, 2020 https://www.bbc.com/news/science-environment-52126735 It is debatable whether wearing a mask if you are healthy will stop you from catching the virus. One of the main reasons a lot of people wear them is because they think it will, personally I have no problem with this if it makes them feel better, but it does give a false sense of security and most available masks do not seal the nose and mouth and are handled incorrectly. However, it does show the way hype affects somebody's thinking and attitude, whereby the people wearing the mask think that this will protect THEM from catching the virus, it is fact that most masks are not worn to protect other people. A mask can be considered as PPE and yet inexplicably a big percentage of the Thai people that wear a mask will not think twice about jumping on to a motorbike without putting a crash helmet on, where statistically they have far more chance of being killed or badly injured.

Thank you for posting the above, I don't get it why some don't get this very simple proposition. The authorities know the above, and IMO the only reason why wearing masks is not mandatory , is because they are not available to everyone, and they want them available for those at high risk such as hospital workers etc. I am convinced that if this virus persists and face masks become more widely available they will become mandatory to wear in public, because it would reduce the transmission rate by that factor. In the absence of an effective treatment and/or inoculation, the only way forward is reducing the transmission rate. If such transmission rate can be reduced to below 1:1 the virus will die out on it's own. 3 Link to comment Share on other sites More sharing options...

That's one person every 5 days in a country where about 1600 die per day of all causes. Thailand didn't end up with this amazingly low mortality rate due to anything they have done as they were very slow to react. They also had more contact with Chinese tourists than most other countries. However, it is reason enough to destroy their economy.

Using the Johns Hopkins dashboard you check the number of cases for Germany (not obviously 100% accurate but more accurate than any other country's), then you take the deaths as a percentage. You get a mortality rate of 1.19% Compare this to South Korea, perhaps the only other country with half-way credible figures, like Germany. You get 1.69% So even with yesterday's unusually large increase in the death figure for Germany you will see that Germany's mortality rate is considerably lower than South Korea's. In South Korea mask wearing is common, in Germany is not. Therefore in terms of Covid19 mask wearing would not seem to make any difference whatsoever.
