Yes I had a social distanced coffee with someone yesterday. She wore a mask and then after wearing it only covering her mouth the entire time she then just pulled it down completely, totally negating the entire point of wearing one in the first place We’re in Italy and are allowed to meet up now.
Right! Most people wear dirty masks, keep touching masks, take off and put on masks, etc, putting people at INCREASED risk. Go out and watch-you will witness this all over.
Leslie H yes I have witnessed people wearing some dirty mask over this last week , obviously stained and with a moist ,warm environment is a veritable cesspool of bacteria..
@@leslieh3785 I see misuse of the masks all of the time. I also see these used masks all over the ground, in shopping carts and on transit where I live.
Yes we dont need to wrar one i live by the sea and need to get air got asthma. So grandaugther no mash for us. I been out every day at shops and sons will not wear them it all fear mongers
get a reusable half face respirator. Due to the separate exhaust valve, they don't restrict breathing or increase CO2 levels like disposable face masks do. They look ridiculous, but they actually work to filter air too, being able to get a full seal on teh face, that disposable masks can't achieve & if you have asthma severe enough for your doctor to be discussing a mask's impacts on your breathing, you're going to be at high risk with this virus & so need to protect yourself. Be sure to shower & wash everything down when you get home, or wearing it is useless! I have asthma myself & wore my half face respirator almost everytime I went outside for nearly 3 months this summer, due to living in Australia, where we had constant extreme smoke. Anytime I tried to go out without it on, I immediately got a severe asthma attack. It got to the point where it became such a routine for me that on one occasion I took it off to talk to someone, cause I didn't think the smoke was THAT bad that day & I found there wasn't ANY smoke in the air & I was walking around looking like an idiot for nothing lol At the opposite extreme, I tried to sunbake one day & had to give up, because not only was there no sun due to teh smoke, but I got covered in ash & my eyes were filled with it, but I couldn't smell any of it & had no trouble at all breathing because of the mask, so yeh a half face respirator will work if you need a mask for this virus :)

I wonder what the actual infection rate would have been if both cages were masked at the same time, stunningly low I presume? Another great video, thank you.
One could guess it would be a 5% infection rate, based on 33% (group B infection rate) of 15% (group A infection rate). It's logical unless the specific viruses that made their way through the infected hamsters' mask were exceptionally good at breaking through barriers and would go through the healthy hamsters' mask as well.
one can speculate by combining data, and I calclulate that the 66 hamsters in the well cage who got sick are reduced to only 8. It's worth it to me to wear a mask.
So, I'm very confused. why the scientists in Europe didn't do experiments to prove whether this method is useful or not? What they did in these 4 months?
What about the scenario when both, the infected and non infected hamsters are wearing masks, what would be the transmission rate in that case?🤔 That is actually the scenario in world where all the people would be wearing masks.
Around 80-90% less infections. That was already calculated else where by determining how the viral load is lowered by different filter fabrics in both directions. 3 cities in Germany went from high to moderate infection rate to ZERO new infections within 2 weeks.
@@pteppig o Belice ebay shivam meant was the result within this test . Comparing results from completely different types of tests is not really proportionate.
well-meaning doctor, but there are many studies with no bias that demonstrate opposite information in this video. There is a video "ANTI-MASKERS: RIGHT OR SELFISH?" on The HighWire channel here on YT with Dr. Denis Rancourt, who has looked at many randomized, controlled studies.
this guy gets a cent from every mask he sells from china, doctors are trained to wear masks and its not easy, you can not touch the mask while its on, before you put it on you have to sterillise , when you take them off you have to sterillise, you should only wear them once and for a short time and so on other wise they cause much more harm than good
@@jingoozrajaii53 too many brainwashed and have bought into the fear propaganda to receive this information...very sad really that the non biased scientific studies are being ignored.
That would be 33% of 15% So 5% maximum. Also, the "healthy hamster" rate would drop if the velocity is reduced. That 5% would be reduced considerably, probably to virtually zero.
Based on the results, it would seem to be a mathematical progression so I am thinking it would be 1/2 of 15%.. Also I am interested in social distancing and would like to see some testing on that. Shots I have seen of students in Taiwan show them going to school, wearing masks and something to do with the feet, but not maintaining social distancing. Also, these tests had a duration of a week, that they were in proximity for that amount of time....
@@marybusch6182 Vietnam pop singer created a catchy PSA dance to air over TV showing hand washing techniques, and another country showed the importance of wearing a mask, a door greeter at stores with hand sanitizers etc. Not all of this back and forth between news outlets and politicians. We'd rather bicker over here.
The is OLD news . "Peak Prosperity" channel was saying this in January. It really should not take a "study" to figure this out. Waiting to be "told" what to do by so called "experts" has been a big part of the problem throughout this pandemic. We have lost the ability to THINK for ourselves. Some more than others :)
Some people only believe things if it's 'scientifically proven'. Although even the media ignores this stuff even when its corroborated by heaps of studies
Yup... I've known for years now that people in Asian nations people wear masks because they have a flu or bug and they wear the masks to stop themselves from spreading it, not to stop themselves from catching it. This is common knowledge... why does it take an expert to inform people of this (and no doubt the same experts that said wearing masks isn't beneficial).
@EmtronVenger you don't agree with the video then,prevention....? Let's assume everyone who needs to wear a mask stays at home,great,no need for lockdown.
1:24 I think the flaw in this argument is the assumption that the distances listed by JAMA are fixed, when they depend to a great extent on the amount of circulation in the space. Another faulty assumption is that getting exposed to any virus at all would be a catastrophe when the truth is that the vast majority of people who acquire immunity (20% of NYC residents) are never seriously ill, so avoiding the virus altogether is not only unrealistic for most people, it it will put off herd immunity and force us to live in this siege environment for even longer. I can see requiring masks on sealed subway cars and buses, but if you can walk through the supermarket keeping a 6 foot distance most of the time and keeping your mouth shut most of the time, you won't be a threat to anyone. Meanwhile, masks are terrible for the people who use them, starving the body of oxygen, raising blood pressure and re-introducing the bacteria, fungus, mold and viruses that the lungs are trying to expel, so they should be worn only when absolutely needed. And, finally, I have to ask, why are the public transportation vehicles still running in so many places with all the windows sealed? The first response to this virus should have been to replace windows with screens and grates in as many normally sealed spaces as possible, including vehicles, bars and shops; dealing with the cold would be far healthier than wearing little petri dishes on our faces all day. Note that the following story covers not only a collapsed lung, but 3 deaths in addition to that, although the conditions that led to this were far more extreme than a trip to the store. There was also a woman in NJ who passed out behind the wheel after driving with a mask for a number of hours. www.dailymail.co.uk/news/article-8311179/Joggers-lung-collapses-ran-2-5-miles-wearing-face-mask.html
Completely agree with the windows problem. I was ranting about that long before COVID. How asinine, truly! And it’s not only buses, it’s all the new buildings with air ducts instead of open windows, especially in educational institutions and offices. How was that ever legal, never mind thought of as good practice by engineers?
That's the point. It has a large impact on how fast an infection could progress. So, with 60-70% less viral load, would make the difference between "stay at home" and " ventilator"
@@freebirdh604 Yes, he did and he also indicated that in your own home it is not necessary nor is it necessary outside because of the air circulation. He also said windows should be open do decrease the viral load in the atmosphere. This is a real problem in most of our buildings now.
@David Liptrot the SARS-COV-2 virus is highly contagious and lethal. It's airborne and spread by particulate and aerosolized droplets. So a well fitting mask is essential. The whole point is to filter the air one breathes so as not to breathe in virus. Surgeon's masks are designed to keep the surgeon's spittle and sweat inside the mask and out of the patient's open wound during surgery. Surgeon's masks are designed with an air gap on sides that would let unfiltered air in. So there is a big difference between types of masks and the effectiveness of masks in preventing airborne infection. At this point the idea is to try and get people to wear masks so asymptomatic carriers and symptomatic carriers of COVID-19 do not spread their virus particles to others. I frankly think it would be a lot more effective to just tell the truth to the public and say " Hey we are dealing with a highly contagious and lethal AIRBORNE virus that isn't going away anytime soon. " But the government knows there are not enough P95 masks and doesn't want people to panic. So they are not being direct and to the point. I wonder how many people would resist mask wearing if they knew the truth. I have been wearing a respirator, eye Protection and gloves in public since January 2020.( I refinish furniture for a hobby. )I got a lot of criticism for it. Now I personally know 18 people who have died of COVID-19. Tried to warn people. They didn't listen. It's very sad. I'll be wear my PPEs in public for many years to come. I am sending love and hugs from Washington State, USA, Jeanne of In Loving Hands Counseling and ASMR.
More death creates more fear and government benefits from that. There is also a deliberate economic destruction of weak cultures in the western world happening. It also saves on pension payouts and the lockdown recession gives an excuse for central banks to ail out the investment bankers and corporate CEOs as well as greasing the palms of government funded academia and of course big pharma. A lot of people are profiting from this debacle.
What kind of mask was used in the experiment? It seems to me to be of paramount importance to know this, as a cloth mask can be a vector for infection to the wearer because of the moisture generated after a few minutes. A damp mask permits transmission through cloth, particularly if it touches the mouth. If hamsters were infected despite dry mask simulation, it would be interesting to see the result if the "mask" was damp.
I'm in the pro mask camp but it's a very good question. If some measures were taken to ensure that both the inside and outside of masks remain moisture free then this can only be a good thing. A changeable moisture absorbing layer on the inside of a mask would suffice, as well as regularly changing a moist mask for a dry one when in public. It's worth taking as many precautions as make you feel safe and it may be found to be necessary at some point - so still worth getting the answer.
They used standard surgical mask, click the link in the description, Dr. John linked the study. We promote standard surgical mask here in HK, only when we don't have it we look for alternative.
cloth masks actually did better than surgical masks in stopping covid-19 in a human study www.acpjournals.org/doi/10.7326/M20-1342 In reality, the masks were beyond sneeze distance from the hamsters faces, so the materials & dampness are irrelevant as a result. All this study did was replicate the Korean call centre results, where cases were dependent on air flow in the area. Set up a fan blowing from infected to healthy & they will get sick. set up a barrier between the 2, to divert air elsewhere & they're less likely to get sick. Continuing the study to give a full week of exposure makes it useless though anyway, as incubation period can be anything from one day, so for all we know, 1 hamster got infected from a single stray droplet & then passed it on to all hte other hamsters in his cage
You stated that we should wear a mask to flatten the curve and not overwhelm health services. Dr. Campbell, you were converted by this one _ingenious_ study? I have heard other doctors speak critically of the suggested policy of widespread mask-wearing. They have described various risk factors that you haven't mentioned. I would be interested in hearing your understanding of how scientific consensus works, and just how many studies are required before that consensus can begin to form.
@@PikesCore24 YT didn't notify me of your comment (a recurring problem). Everything you do has risks attached, including deciding to wear or not to wear a mask. I suspect a common problem is believing that the mask will protect you in a situation where it doesn't. An infected person who sneezes in front of you is releasing a virus-filled spray that is quite capable of passing through most masks and face coverings. The N95 mask is the best one, but even it doesn't provide 100% protection. There are numerous other risks, including reduced oxygen supply, cross-contamination from touching the outside of the mask, gaps around the edges, and more. Educating yourself, and social distancing are more effective strategies.
@@johnlvs2run I disagree. There are very smart (but misguided) people who advocate wearing a face covering. The problem is the science doesn't actually support this policy at this time. It is a "strong feeling" or personal opinion of various experts that could turn out to be entirely wrong. Social distancing is a better policy, and ordinary vigilance while out among people.
@@misterlyle. SARS-CoV-2 is about 120 nanometers in diameter. The filtration efficiency of N95 masks with sodium chloride upstream propelled particles of size 120 nm can have between roughly 95% to 100% coverage of particles (multimedia.3m.com/mws/media/376179O/nanotechnology-and-respirator-use.pdf). Wearable cloth coverings vary in efficacy but still range between 80% and 100% with sodium chloride upstream propelled particle of size 120 nm at approximately the same rate of flow (pubs.acs.org/doi/10.1021/acsnano.0c03252, Figure 2 and Figure 3). Silk seems to be the best material. Nevertheless, wearable cloth coverings worn correctly, with proper procedures in place to stop cross-contamination, as Dr. Campbell suggests, are without a doubt better than nothing. The people who advocate face covering are not misguided. Unfortunately, the enforcement of social distancing policy as you say does not seem like it will happen to full efficiency. It is very hard to make people follow such policies in the western world. We have seen in the past few days what social distancing means: Riots, picnics, and protests. Doctors are only advising the correct application of cloth based face masks to people who choose not to follow social distancing guidelines.
Said it before and I'll say it again - Taiwan never locked down (cinemas, cafes, etc. all open) and has the grand total of 7 deaths from 441 cases. It's not just the masks, they are just one of the tools used, but they have certainly helped.
I was starting to visualize the scientists tying little masks on each hamster until John said the cage was masked, not the individual hamsters because "that would be silly" 😳🤣🙃
Can anybody explain/guess why our authorities seem reluctant to even play catch-up with best practice around the world (testing, zinc, vitamins, masks, etc). Our system seems designed to maximise economic disruption/mental health problems/mortality - bring on the conspiracy theories. Tens of thousands of lives could have been saved and based on current performance, we may have to go through it all again next winter.
Because nearly all politicians are incompetent and only listen to pharma lobbyists instead of doctors. Billions for a vaccine that will be ready when the flu is gone. Like the last 2 times. and later a cushy job at that company.
In short, no I can’t, I cannot even think of a secret agenda that might explain it. The only conclusion I arrived at is gross incompetence and they should be held accountable for gross man slaughter. Apologies! I’m just getting more and more frustrated with our UK government the more I understand about the virus.

"They always wear masks..." and where do these virus's mostly originate? Also what about the potential for hypoxaemia and the cloth mask getting warm and moist...consequences?
Eileen, you nailed it! That short rhyme could be written on the mask. Understanding wearing a mask is for others and not themselves may increase voluntary compliance.
I also like to know if they used different masks in this experiment... Had a Santa Clause mask the same effect as a Guy Fawkes mask? And what about a Bux Bunny mask or a Donald Trump mask? They need to put a lot more money in this essential and scientific experiments... to get proper results.

Thanks a lot and greetings from Toronto/Canada! The hamster experiment is the best to visualize what's the purpose of wearing a mask. We appreciate your videos, John!!!!
He kind of lost me at "We have to flatten the curve; so everyone must wear a mask". The mortality risk is clear now. It is not the general population. Getting a mild infection which creates protective antibodies is not a major medical problem. This is necessary to control the duration of the pandemic. It is epidemiology 101 and called Herd Immunity!
Russell Buskirk Death is not necessarily the worst thing COVID19 does. It’s already shown it can cause long-term organ damage in even asymptomatic or mild cases.
@Yogurt Slinger because it’s not a cold. There are many cases of diabetes linked to a prior COVID-19 infection and there are several reports about neurological and organ damages caused by it. I know many doctors and nurses and I‘ve heard quite some horror stories about 30 year olds with no pre-existing conditions which were close to death and totally wrecked after a COVID-19 infection (and they work in different hospitals in different parts of the country). Just because you didn’t experience it yourself or know anyone who really suffered doesn’t mean it doesn’t exist...
I think PHE and the UK Government were fully aware that masks massively reduced the rate of infection, it is simple science after all (we all know condoms work!). The problem is they didn’t have enough stocks for NHS staff let alone the public and they didn’t want to people to panic buy the absolute PPE from suppliers.
I love this so much. This is far and away Dr John's best video to date. However I remain slightly disappointed that the hamsters were not wearing tiny, perfectly fitted masks.
When I go to a store its my choice to do so. The people who work there have no or little choice in the matter! If my wearing a mask when I decide to go there, makes them safer. That's enough for me, ill wear a mask.
Pinak Kapadia but if you don’t wash them constantly or purchase mass amounts it won’t work oh and you can’t wear any of them for long periods of time.. so there is always that
I wonder what the infection rate is if BOTH cages have protection? Is it even lower than if only the infected hamsters were protected? (Why we should ALL be wearing them).
Only if you believe discredited scientists who were never very recognized in their field, who have been jailed for stealing from her employers, and was all about creating vaccines until it suited her not to be.

The efficacy and safety of vaccines have never truly been tested and Judy Mikovits is not the only one to make the claims she has made concerning this virus.
@@sueeason275 Up to 25% of the population can be Asymptomatic or Pre-syptomatic at any one time and therefore spread the virus. >>> Everyone wearing a face covering Rate of transmission goes down by 95% mathematically speaking.
Thank you ,too many in USA think a mask is tyranny ( because of extended lockdown) and are refusing to ware one. I think like Taiwan and Slovakia we should have worn them from day one, and not lockdown or just two weeks.
Because some governors behave like tyrants. Like Gretchen or commie coumo. Make masks mandatory and stop the lockdown. They should finally stop the lockdown and the resulting social Crysis.
I wouldn't brush off aversion to masks as a fear for tyranny. There IS an actual huge downsides with masks: it hides your body language. Something in the order of 60% of communication consists of body language, and your facial expressions is a HUGE part of that. This means you can't judge what a masked person is thinking, the emotional state of that person, and even if you talk to the person, the communication is more akin to talking to a machine. This is absolutely a problem and a big reason why mask wearing should not become part of our daily lives.
This has been the most logical fact since day 1. They wore them in the Spanish flu they wore them for Sars. I think they even wore them for the black plague back in the day. China made them mandatory in Wuhan. Numerous other countries have made them mandatory for covid. In my country Australia the chief medical officer for our country said they did not work for the public and this is still the statement that exists on the national broadcaster ABC website. Also by the way there have been other studies from the past saying exactly the same as this study.
If mask wearing wasn't a hallmark of this whole plannedemic, this study would be hilarious. Seriously, the only study in support of masks involves hamsters?!! There are studies done on healthcare workers that show that masks are not only ineffective in preventing infection but long term use is detrimental to health.
bernadette reilly, to simply ask it would get you nowhere as there will always be people who think they know better or this doesn’t apply to them. It has to be made mandatory. How about “No mask wearing, No tube/bus faring”. Ideally they should also place hand sanitizer dispensing stations by the entrance gates...
What's striking me is that we've become so detached from reality that even the most obvious common-sense findings like those ones are a surprise to us.
These are not “common sense.” Common sense tells us that if mask wear were so advantageous, we (or certainly other species) would have developed organic protective masks through evolutionary processes. It is not common sense to breathe your own breath.
was the ebola outbreak a psyop? was the 1968 outbreak a psyop was the outbreak in 1917-1920 a "psyop" jesus christ everything is "psyop" to you guys now
Well, the USA isn't doing much better. In fact, we have a "president" who won't wear a mask because he thinks it makes him look weak and it will smear off his orange spray tan! Vanity is more important to him than saving lives!
Hi Dr John, I’m so thankful that I finally heard how convinced you are now to advise for everyone to wear masks. I still remember months ago that there was a little hesitation in your voice when you talk about masks wearing. Grateful for you & for all your research/studies as always! Stay safe! ❣️

interesting results re hamsters... did they not try both cages masked with infected in one and uninfected in the other? would be interesting to see how much infection there would be there in the healthy hamsters because at the moment they have one or the other covered or neither covered.
I can see several problems with this experiment, though. For one, the masks weren't actually on the hamsters, they were on their cages. So the hamsters weren't actually coming into contact with the masks themselves. Of course it would be highly difficult to get masks on the hamsters in the first place because they would fight them and try to get them back off as much as they could. People often do the same thing because the masks irritate their skin around their nose and their mouth. So they are often touching and adjusting the masks with their hands and scratching the skin around their nose and mouth which studies have shown pretty much negate their effectiveness. When I've worn a mask for more than a few seconds my chin starts to itch terribly. I suspect this is because, as a man, I have facial hair growing all the time. Even after I've shaved, a few hours later I have stubble because my facial hair doesn't stop growing. So I can shave in the morning and by lunch time I have stubble. Put a mask on and my chin itches like crazy. I would have to shave every few hours to keep that from happening. Another problem with the experiment is that the hamsters were kept in separate cages. To be more like a real world experiment they would have to take the infected hamsters out of their cage and let the uninfected hamsters in their cage for a while. This would be like infected people going into public places with masks on and then leaving and then uninfected people coming into the same public place later, which is more real world where people are touching the same surfaces in public places all the time. Masks aren't going to have any effect on that. There was another experiment I saw a video on a few days ago that was interesting. In it the staff of several hospitals was divided into 2 groups--group one wore N95 masks while group 2 wore surgical masks. They wore these masks thru flu season last year. The group that wore N95 masks had about 8% contract the flu anyway, while the group that wore surgical masks had about 7% contract the flu anyway. This seems counter intuitive since N95 masks are supposedly better at filtering out smaller particles than surgical masks. In the video it was speculated that perhaps people touching and adjusting their masks because of skin irritation by them led to the higher infection rate by those wearing N95 masks because those masks were more secure on their faces and therefore irritated their facial skin more. I thought that they needed a control group who wore NO masks just to see if even wearing a mask made any difference. But of course hospital staff have to wear masks because of their job. But then I searched online to see what the average was for people in the US contracting the flu in an average flu season and was surprised to find one source that said on average about 8% of people in the US contract the flu every year. That's about the same percentage of people who contracted the flu wearing the masks in hospitals during flu season last year! Maybe they were subjected to a higher viral load because they worked in a hospital environment during flu season. But still. Hmmmm.
Not worth it. Destroy a fundamental part of our culture, for a disease that has, ultimately, been as bad as a bad flu season? No thanks. Life is about balancing risks, costs and benefits. What's the point of saving a few lives of everyone who's left is worse off? "We should not have fought Nazism, because people died." No. No. No.
Did anyone else notice that people who put NHS stickers up their windows and clap on Thursdays are the same people who don't wear mask, don't do social distancing and break lockdown regulations?
And voted for Brexit and failed to keep out the Conservatives again. Unless you voted against the Tories, you have to take the blame. They cut the NHS to ribbons.
@David Liptrot The lockdown was to protect HNS being overwhelmed. If it wasn't so, people would have started a revolution and thrown Johnson and most ministers over the cliff. HAD the lockdown been done to protect the people, it would have started WEEKS earlier with increased testing and tracing as WHO advised... itself too late to react..
I could never understand why people in the US never bothered wearing masks years ago, when so many people caught the seasona colds and flu in winter. Even if the flu doesn't wind up killing you, who wants to be miserably sick for a couple of weeks. Those pleated surgical masks were cheap and easy to get before this virus hit, so such a small investment could have saved people from getting ill a long time ago.
There is scientific evidence that proves wearing a football helmet whenever you are in a car saves life. That doesn't mean we should wear helmets in cars.
On the contrary it proofs we should. Absence of logic.Different matter that we cannot bother.Racing cyclists for years never wore helmets but now complusary.Motor Bike?
@Miss Information Misinformation, indeed! If wearing a mask is deadly for you, then please protect yourself by staying home. Let the rest of us wear masks out in public, to cautiously/safely get things rolling again.
Thank you for this! I've made masks for the whole of my family from old t-shirts & have been wearing a mask for months now at work (I'm a nurse practitioner) and in public (shopping mainly!). Please please tell me the UK government are aware of this research? Let's hope it is mandatory very very soon.
I hope not mandatory for me. It could kill me. CO2 retention underneath a mask can be fatal. So, I guess lockdown at home for a long long time is my answer. www.dailymail.co.uk/news/article-8332037/People-lung-conditions-NOT-wear-face-masks-makes-hard-breathe.html

Funny, Dr. John should have done his homework back then about “the science” that we knew since the Spanish Flu that mask had little to no effect. Here is Dr. Campbell apologizing for this nonsense on masks with him reviewing the new Cochran Study that proved that masks, had little to no effect on the spread. ua-cam.com/video/S3vY2LyQn1A/v-deo.html
Are viruses alive, or are they dead, do viruses replicate, or are they produced inside of a cell and ejected from the cell to perform a specific task. Can a person catch HIV, Herpes, HPV, from coming within 6 feet of someone having those viruses, like passing them on a sidewalk, or touching an item they handled, if a person who has HIV sneezes, do we catch HIV because we are in the same room with them.
Dr. Campbell please please please see if you can find any data on what happens when both the hamster cages have masks attached to them. I think it’s a critical point of information that we need. Thank you from Canada

If you have a forced air furnace, I would suggest you check the Acoil and plentium for molds. Then retrofit the furnace air filter system with 4 inch filter rack and a Merv 13 filter. Then install a UV light system on the intake side and the Acoil area then the out put side. Then you have a virus,mold,and particulate filtering machine your house. That is what I did way back in February.
Most masks including FFP3 and FFP3 masks are specifically designed to protect the person wearing the mask. It may offer very little protection to others as suggested. This is due to the one way valve that allows unfiltered exhaled air out. Therefore if someone sneezes, coughs or even breathes the the positive pressure within the mask will be released into the air via the valve as this is path of least resistance. This exhaled air will not have been filtered!! Therefore more sophisticated masks such as these should be reserved for NHS staff as the priority should be that they protect themselves. I completely agree that non valved masks or home made face coverings should be worn in the community by everyone. There should be lower transmission rates than the hamster tests as both the infected and non infected persons will be wearing a mask. I just wish the UK government would wake up and encourage face coverings!!
This is were Boris and Hancock messed up, gave this advice too late during the pandemic. The thing is as the weeks are going by, less people are wearing masks in shops and on transport, so potential second peak on the way.
@@peterpeters2412 the evidence was there all of the time but it met the political narrative to create a climate of fear and control. Now the evidence has got out and been reinforced by new studies
An Excelent and very encouraging video Dr. Campbell... I just wish people in charge of the health department and the goverment in Mexico could understand the facts you've just presented here. They keep on saying that simple masks are useless whatsoever up to this very day...
I'm in the states. It's becoming increasingly difficult to deal with my fellow citizens on this topic. There's funny anecdotes comparing mask effectiveness to a cotton condom. Though it's funny, people here literally don't believe it works especially when they discover it's not a respirator lol. Thank you for keeping me sane, these factual videos from people like you are important.
The better anecdote is comparing people standing next to each other and peeing. If they're both naked, the peeing guy will get his pee all over the naked non peeing guy. If the non peeing guy is wearing pants, he'll get some pee on him but not as much, but still a lot, depending on the porousness of the pants. If the peeing guy is wearing pants, he'll have the pee mostly on him with only some pee getting outside the pants and onto the floor, but if the non peeing guy's still not wearing pants and/or socks, he might still get some on his skin but even less. Now if they're both wearing pants and/or socks, there's the least chance of pee getting on the non peeing guy and even in the slight chance, there's the least amount of pee. A crude, but very effective description...
To mask or not to mask has been causing division here that is beyond common sense. Instead of looking at fact (what the science/research shows), many people I know see mask-wearing as a political/cultural issue. As a person who has immune system dysfunction, I see it as life or death. This discrepancy has caused a lot of stress between me and people I call my friends.
reality is, it appears to be not factual, but rather just a quick fix to con people & get them happily going back to work to restore the economy, thinking they're safe because of their mask when it's purely a placebo. Hamsters with a mask attached to a cage wall over sneeze distance from their faces is NOT a valid scientific experiment on this! An experiment like that is only going to get massive coverage on all media if it's consistent with the line the government/s want told. All mask wearing countries have seen spikes in cases weeks after containing the majority of cases & enforcing mask wearing for all, showing the masks are NOT working! The only countries that haven't seen these spikes are New Zealand & Australia, who do NOT wear masks! The exception being that Australia saw one new cluster of cases in an abattoir, where workers wear masks for hygiene reasons. Remove the masks & the clusters vanish, that's the reality! Australia & New Zealand however are insisting people are to be tested & then stay home if they have even a sniffle. Countries like the US & UK aren't willing to encourage that, because it will impact on productivity & so they roll out this fake "wear a mask & your protected" propaganda www.acpjournals.org/doi/10.7326/M20-1342 www.abc.net.au/news/2020-04-04/coronavirus-covid-19-face-masks-paul-kelly-australians/12122042
@@cb4435 the one type of mask that will work is a proper, reusable half face respiratory, with fully washable silicon face seals & seperate inlet & outlet valves. I suggest you buy & wear one of those if you have a need for genuine protection from this virus. Remember though, unless you do proper washing to accompany it, it's useless! You need to be wearing it consistently from when you leave your home to when you get back home & on arriving home, you need to be heading straight to your bathroom/laundry, removing the mask, pulling it apart for cleaning, striping your clothes into your washing machine & then getting into the shower & fully washing your entire body, hair etc & the mask with soap & water for at least 15 minutes, then going back to any door handles, taps, washing machine controls you touched & washing & disinfecting them. If you're not doing all of that everytime you go out, you're kidding yourself to think your mask is useful
Dr Campbell, thank you so much for doing this video. It has frustrated me so much that the UK Govt and its' scientific advisors have almost obsessively focussed on dissuading us to not wear masks, even telling us it could put us at more risk at some points, and even now only "if we want to - not mandatory" when in public internal places. I have had really positive personal success with reducing colds by wearing them in planes and public transport for months before this outbreak happened that I have been convinced about their value also for reducing risks. Before I would get regular colds and this often resulted in 2-3 months long exhausting coughs and it would have roll on effects to other aspects of my health. So finding ways to stop this was very important to me for my quality of life. Mask wearing in public transport myself has made a significant difference to me. And as you say, the empirical evidence is also clear from the countries which have worn them in public and also had best success in reducing the scale of the outbreak. I understood from a presentation by Professor Lum as part of the UK Health and Social Care Committee expert panel discussion the other day that in Hong Kong they also didn't really lock down - but they had 97% of the population wearing masks by March (along with the track and trace and quarantine) and in January they mandated all care workers must wear masks. They did not have a single COVID infection in care homes and not a single health worker death. Now that's really impressive. I have seen in my own work that sometimes an 'expert' has a particular take on something and then because they say it loud enough and they are respected, many other people start saying the same thing and it becomes a kind of 'fact' that others are looked down upon if they contradict. I think that is also what has probably happened here and it hasn't helped that the WHO also didn't come out and strongly advise to wear them, giving more justification to a government like ours to ignore the experience in the countries which previously fought SARS. Hopefully now that we can see how badly we have done against these other countries, this will be revisited, but that needs the experts advising the government to also be a bit humble about their misjudgement... I am doubtful as to whether that will happen... although I guess they can just say... "with the new evidence... we are now changing our advice".. even though the evidence has been there for some time. In case you are interested please also see this post re some mapping we did on the UK govt guidance to care homes and the major issues with it. We continue to be very concerned about the fact that the government still continues to not talk about asymptomatic and pre-symptomatic transmission (thank you also for raising this in your video) - as until it focusses on this in its guidance to care homes the risk of spread will continue: ltccovid.org/2020/05/15/mapping-of-uk-government-guidance-for-infection-prevention-and-control-ipc-for-covid-19-in-care-homes/
What drives me crazy is that authority and experts in the West were telling people not to wear them!! It's hard to find trustworthy sources of information, but this doctor is one I do trust.
Thanks Dr. John. Thank you for the detailed explanation on this situation. I'm here in Singapore. We were advised to wear mask in public places all the time. If caught, there's a fine for not wearing. Stay safe Dr. John.
You probably meant to say face mask wearing was made mandatory in Singapore. The same should apply here...by simply asking to wear one would not work as there will always be people who will feel it does not apply to them.
Edinburgh University did a fantastic study months ago and the results were fantastic!! They tested a range of different masks and fabrics and everyone showed great rates of protection. I immediately bought a small amount of masks for my family and found out how we could effectively and safely rotate them, so they could be reworn many more times than they normally would. We were amongst the first to use them locally and worried about it simply because we were told by Government, we would be talking those masks away from frontline staff. I thought it was unlikely the seller l bought from on ebay, would be approached by my Government to supply masks for our hospitals. So we soon got over those concerns and none of us leave the house without one anymore.
Morning my friend hope all is well . That why i wear a mask i could not live with myself if someone died or got it from me a wish i could get tested even tho i dont have symptoms lol take care much love xxx
Hi Kevin. Ignore the harrassers. I think it's fascinating how things that are so obvious (benefits wearing masks) are looked upon with a blind eye, when the (outdated) social norms say to do otherwise. I also think the early recommendations to not wear mask were to conserve masks for hospital workers, prevent hoarding, and (sadly) to allow facial recognition software to keep working. one also can't ignore the outdated social stigma against masks that sadly seems to exist. peace, carol
19:04 SUGGESTIONS!! "If you Care, wear!" "Wear to Care" "Don't Spread it / Don't Catch it!" "Let's face it! ...together!" You choose Dr Campbell...or maybe find even better one!! All good! ;D kekkkee!
*unfortunately, politicians and scientists are not on the same page vis à vis Covid- 19 prevention: the lack and the shortage of masks make false policies* .
What drives me crazy are the people who wear a mask over their mouths, but leave their noses exposed. Sort of defeats the purpose.
Ikr!
You;re right I've noticed too.
Yes I had a social distanced coffee with someone yesterday. She wore a mask and then after wearing it only covering her mouth the entire time she then just pulled it down completely, totally negating the entire point of wearing one in the first place We’re in Italy and are allowed to meet up now.
This is the reason it's pointless. People don't understand it and it's antithetical to our culture.

Im afraid my own doctor suggested mask_wearing for me could be dangerous because I suffer from asthma. I would like to hear your comment Dr Campbell.
Yes we dont need to wrar one i live by the sea and need to get air got asthma. So grandaugther no mash for us. I been out every day at shops and sons will not wear them it all fear mongers
get a reusable half face respirator. Due to the separate exhaust valve, they don't restrict breathing or increase CO2 levels like disposable face masks do. They look ridiculous, but they actually work to filter air too, being able to get a full seal on teh face, that disposable masks can't achieve & if you have asthma severe enough for your doctor to be discussing a mask's impacts on your breathing, you're going to be at high risk with this virus & so need to protect yourself. Be sure to shower & wash everything down when you get home, or wearing it is useless!
I have asthma myself & wore my half face respirator almost everytime I went outside for nearly 3 months this summer, due to living in Australia, where we had constant extreme smoke. Anytime I tried to go out without it on, I immediately got a severe asthma attack. It got to the point where it became such a routine for me that on one occasion I took it off to talk to someone, cause I didn't think the smoke was THAT bad that day & I found there wasn't ANY smoke in the air & I was walking around looking like an idiot for nothing lol At the opposite extreme, I tried to sunbake one day & had to give up, because not only was there no sun due to teh smoke, but I got covered in ash & my eyes were filled with it, but I couldn't smell any of it & had no trouble at all breathing because of the mask, so yeh a half face respirator will work if you need a mask for this virus :)

I wonder what the actual infection rate would have been if both cages were masked at the same time, stunningly low I presume? Another great video, thank you.
I thought of the same thing, a bit of a glaring omission, in the trial.
That's what I would have liked to see.
This guess by no means matches an experimental result, but it should be somewhere around 15% * 15% (or 0.15 * 0.15) or 2.25% overall.
One could guess it would be a 5% infection rate, based on 33% (group B infection rate) of 15% (group A infection rate). It's logical unless the specific viruses that made their way through the infected hamsters' mask were exceptionally good at breaking through barriers and would go through the healthy hamsters' mask as well.
one can speculate by combining data, and I calclulate that the 66 hamsters in the well cage who got sick are reduced to only 8. It's worth it to me to wear a mask.
Chinese have been saying this since January, they knew what they said!. Thanks Doctor, let's hope people take this seriously
remember when asian people were beaten up for wearing masks in public? This is more than just ignorance
So, I'm very confused. why the scientists in Europe didn't do experiments to prove whether this method is useful or not? What they did in these 4 months?
What about the scenario when both, the infected and non infected hamsters are wearing masks, what would be the transmission rate in that case?🤔
That is actually the scenario in world where all the people would be wearing masks.
Around 80-90% less infections.
That was already calculated else where by determining how the viral load is lowered by different filter fabrics in both directions.
3 cities in Germany went from high to moderate infection rate to ZERO new infections within 2 weeks.
They'd also have to make more tiny masks
This is a really good question
@@pteppig o Belice ebay shivam meant was the result within this test . Comparing results from completely different types of tests is not really proportionate.
Mathematically it would be 0.15 x 0.33 = 5% infected so a lot less than only one group wearing masks
well-meaning doctor, but there are many studies with no bias that demonstrate opposite information in this video.
There is a video "ANTI-MASKERS: RIGHT OR SELFISH?" on The HighWire channel
here on YT with Dr. Denis Rancourt, who has looked at many randomized,
controlled studies.
this guy gets a cent from every mask he sells from china, doctors are trained to wear masks and its not easy, you can not touch the mask while its on, before you put it on you have to sterillise , when you take them off you have to sterillise, you should only wear them once and for a short time and so on other wise they cause much more harm than good
@@jingoozrajaii53 too many brainwashed and have bought into the fear propaganda to receive this information...very sad really that the non biased scientific studies are being ignored.
me: picturing a bunch of hamsters wearing masks
John: it's not like the individual hamsters were wearing masks that would be silly.
me: >:(
It's a shame they didn't test both cages with masks. I'd like to see the total infection.
That would be 33% of 15%
So 5% maximum.
Also, the "healthy hamster" rate would drop if the velocity is reduced.
That 5% would be reduced considerably, probably to virtually zero.
mathematically 5%!! ,95% protection
Based on the results, it would seem to be a mathematical progression so I am thinking it would be 1/2 of 15%..
Also I am interested in social distancing and would like to see some testing on that. Shots I have seen of students in Taiwan show them going to school, wearing masks and something to do with the feet, but not maintaining social distancing. Also, these tests had a duration of a week, that they were in proximity for that amount of time....

And that is a very good Channel to navigate when looking for Corona virus info.
Some people only believe things if it's 'scientifically proven'. Although even the media ignores this stuff even when its corroborated by heaps of studies
Yup... I've known for years now that people in Asian nations people wear masks because they have a flu or bug and they wear the masks to stop themselves from spreading it, not to stop themselves from catching it.
This is common knowledge... why does it take an expert to inform people of this (and no doubt the same experts that said wearing masks isn't beneficial).
Dr John has been saying this for months - he’s just giving us the up-to-date proof to back up what he already knew
Again,why are the professional "experts" so slow to acknowledge these common sense measures,I have been doing this since march in supermarkets
They should be fired!
@EmtronVenger you don't agree with the video then,prevention....?
Let's assume everyone who needs to wear a mask stays at home,great,no need for lockdown.
Because they are dumber than the dumbest
@David Liptrot They are useless against aerosolized viruses, but NOT against the droplets that viruses are attached to!
@David Liptrot My guess is that neither you or your dog are normal.
1:24 I think the flaw in this argument is the assumption that the distances listed by JAMA are fixed, when they depend to a great extent on the amount of circulation in the space. Another faulty assumption is that getting exposed to any virus at all would be a catastrophe when the truth is that the vast majority of people who acquire immunity (20% of NYC residents) are never seriously ill, so avoiding the virus altogether is not only unrealistic for most people, it it will put off herd immunity and force us to live in this siege environment for even longer. I can see requiring masks on sealed subway cars and buses, but if you can walk through the supermarket keeping a 6 foot distance most of the time and keeping your mouth shut most of the time, you won't be a threat to anyone. Meanwhile, masks are terrible for the people who use them, starving the body of oxygen, raising blood pressure and re-introducing the bacteria, fungus, mold and viruses that the lungs are trying to expel, so they should be worn only when absolutely needed. And, finally, I have to ask, why are the public transportation vehicles still running in so many places with all the windows sealed? The first response to this virus should have been to replace windows with screens and grates in as many normally sealed spaces as possible, including vehicles, bars and shops; dealing with the cold would be far healthier than wearing little petri dishes on our faces all day. Note that the following story covers not only a collapsed lung, but 3 deaths in addition to that, although the conditions that led to this were far more extreme than a trip to the store. There was also a woman in NJ who passed out behind the wheel after driving with a mask for a number of hours.

Completely agree with the windows problem. I was ranting about that long before COVID. How asinine, truly! And it’s not only buses, it’s all the new buildings with air ducts instead of open windows, especially in educational institutions and offices. How was that ever legal, never mind thought of as good practice by engineers?
Mask wearing is uncommon in the UK because for the last 3 months everyone has been told masks don’t work! 🙄
They don't
headrat1 Let JAMA know 👍🏻
And the Brits are absolutely correct--> www.lewrockwell.com/2020/05/no_author/masks-are-there-benefits-or-just-a-comfort-prop-let-the-facts-speak/
*Mask wearing is uncommon in the UK because for the last few months the government has been told us that we have a huge masks shortage!* .
Numbers putting here as flattend curve is just because of LOCKDOWN not by wearing masks .
Wouldn't wearing a mask, if not prevent infection, at the very least reduce the viral load one would otherwise inhale without a mask?
That's the point. It has a large impact on how fast an infection could progress.
So, with 60-70% less viral load, would make the difference between "stay at home" and " ventilator"
I think the good doctor mentioned reduced viral load of mask wearing in the vid
@@freebirdh604 Yes, he did and he also indicated that in your own home it is not necessary nor is it necessary outside because of the air circulation. He also said windows should be open do decrease the viral load in the atmosphere. This is a real problem in most of our buildings now.
@David Liptrot the SARS-COV-2 virus is highly contagious and lethal. It's airborne and spread by particulate and aerosolized droplets. So a well fitting mask is essential. The whole point is to filter the air one breathes so as not to breathe in virus.
Surgeon's masks are designed to keep the surgeon's spittle and sweat inside the mask and out of the patient's open wound during surgery. Surgeon's masks are designed with an air gap on sides that would let unfiltered air in. So there is a big difference between types of masks and the effectiveness of masks in preventing airborne infection.
At this point the idea is to try and get people to wear masks so asymptomatic carriers and symptomatic carriers of COVID-19 do not spread their virus particles to others. I frankly think it would be a lot more effective to just tell the truth to the public and say " Hey we are dealing with a highly contagious and lethal AIRBORNE virus that isn't going away anytime soon. " But the government knows there are not enough P95 masks and doesn't want people to panic. So they are not being direct and to the point. I wonder how many people would resist mask wearing if they knew the truth.
I have been wearing a respirator, eye Protection and gloves in public since January 2020.( I refinish furniture for a hobby. )I got a lot of criticism for it. Now I personally know 18 people who have died of COVID-19. Tried to warn people. They didn't listen. It's very sad. I'll be wear my PPEs in public for many years to come. I am sending love and hugs from Washington State, USA, Jeanne of In Loving Hands Counseling and ASMR.
@Andrew Ongais animals and humans. Any barrier helps
From Jan till now, the hesitation towards masks is staggering. Just ideological and idiotic.
Cultural norms are weird ... I'm gonna sleep for hours and hours with a fan blowing right on me.
Lockdown would be unnecessary if they admitted the trut that they were trying to confuse people to make more “contagion” and cause more “death”
@David Liptrot A little c4 might alleviate that problem.
@David Liptrot What about a blow up doll?
More death creates more fear and government benefits from that. There is also a deliberate economic destruction of weak cultures in the western world happening. It also saves on pension payouts and the lockdown recession gives an excuse for central banks to ail out the investment bankers and corporate CEOs as well as greasing the palms of government funded academia and of course big pharma. A lot of people are profiting from this debacle.
What kind of mask was used in the experiment?
It seems to me to be of paramount importance to know this, as a cloth mask can be a vector for infection to the wearer because of the moisture generated after a few minutes. A damp mask permits transmission through cloth, particularly if it touches the mouth. If hamsters were infected despite dry mask simulation, it would be interesting to see the result if the "mask" was damp.
I'm in the pro mask camp but it's a very good question. If some measures were taken to ensure that both the inside and outside of masks remain moisture free then this can only be a good thing. A changeable moisture absorbing layer on the inside of a mask would suffice, as well as regularly changing a moist mask for a dry one when in public. It's worth taking as many precautions as make you feel safe and it may be found to be necessary at some point - so still worth getting the answer.
They used standard surgical mask, click the link in the description, Dr. John linked the study. We promote standard surgical mask here in HK, only when we don't have it we look for alternative.
They used surgical masks, we need another study with cloth masks to see how it compares. I suspect not nearly as good but would be sure nice to know!!
cloth masks actually did better than surgical masks in stopping covid-19 in a human study www.acpjournals.org/doi/10.7326/M20-1342
In reality, the masks were beyond sneeze distance from the hamsters faces, so the materials & dampness are irrelevant as a result. All this study did was replicate the Korean call centre results, where cases were dependent on air flow in the area. Set up a fan blowing from infected to healthy & they will get sick. set up a barrier between the 2, to divert air elsewhere & they're less likely to get sick. Continuing the study to give a full week of exposure makes it useless though anyway, as incubation period can be anything from one day, so for all we know, 1 hamster got infected from a single stray droplet & then passed it on to all hte other hamsters in his cage
The cited research also indicates that non-infected hamsters wearing a mask received a lower viral load which is important.
You stated that we should wear a mask to flatten the curve and not overwhelm health services. Dr. Campbell, you were converted by this one _ingenious_ study? I have heard other doctors speak critically of the suggested policy of widespread mask-wearing. They have described various risk factors that you haven't mentioned. I would be interested in hearing your understanding of how scientific consensus works, and just how many studies are required before that consensus can begin to form.
Anyone who recommends wearing a mask to protect from a virus is an idiot.
What "risk factors" are you referring to? Are you saying that wearing a mask creates a risk of some kind?
@@PikesCore24 YT didn't notify me of your comment (a recurring problem). Everything you do has risks attached, including deciding to wear or not to wear a mask. I suspect a common problem is believing that the mask will protect you in a situation where it doesn't. An infected person who sneezes in front of you is releasing a virus-filled spray that is quite capable of passing through most masks and face coverings. The N95 mask is the best one, but even it doesn't provide 100% protection. There are numerous other risks, including reduced oxygen supply, cross-contamination from touching the outside of the mask, gaps around the edges, and more. Educating yourself, and social distancing are more effective strategies.
@@johnlvs2run I disagree. There are very smart (but misguided) people who advocate wearing a face covering. The problem is the science doesn't actually support this policy at this time. It is a "strong feeling" or personal opinion of various experts that could turn out to be entirely wrong. Social distancing is a better policy, and ordinary vigilance while out among people.
@@misterlyle. SARS-CoV-2 is about 120 nanometers in diameter. The filtration efficiency of N95 masks with sodium chloride upstream propelled particles of size 120 nm can have between roughly 95% to 100% coverage of particles (multimedia.3m.com/mws/media/376179O/nanotechnology-and-respirator-use.pdf). Wearable cloth coverings vary in efficacy but still range between 80% and 100% with sodium chloride upstream propelled particle of size 120 nm at approximately the same rate of flow (pubs.acs.org/doi/10.1021/acsnano.0c03252, Figure 2 and Figure 3). Silk seems to be the best material. Nevertheless, wearable cloth coverings worn correctly, with proper procedures in place to stop cross-contamination, as Dr. Campbell suggests, are without a doubt better than nothing. The people who advocate face covering are not misguided.
Unfortunately, the enforcement of social distancing policy as you say does not seem like it will happen to full efficiency. It is very hard to make people follow such policies in the western world. We have seen in the past few days what social distancing means: Riots, picnics, and protests. Doctors are only advising the correct application of cloth based face masks to people who choose not to follow social distancing guidelines.
Said it before and I'll say it again - Taiwan never locked down (cinemas, cafes, etc. all open) and has the grand total of 7 deaths from 441 cases. It's not just the masks, they are just one of the tools used, but they have certainly helped.
HK has 1029 cases and 4 deaths. We all wear masks from day 1.

Can anybody explain/guess why our authorities seem reluctant to even play catch-up with best practice around the world (testing, zinc, vitamins, masks, etc). Our system seems designed to maximise economic disruption/mental health problems/mortality - bring on the conspiracy theories. Tens of thousands of lives could have been saved and based on current performance, we may have to go through it all again next winter.
Because nearly all politicians are incompetent and only listen to pharma lobbyists instead of doctors.

But staying home’s the thing to do,

For family and friends,
It’s just one way to keep in touch
Until this madness ends.

If only they would do the dishes,
Cause I’ve done a lot more cooking
Eat at home, no restaurant booking.
I’m grateful that I’m not alone,
My guy, my dog, the cats, my phone.
A chance to clean the house for spring,
And hope to see what time will bring.
I pray this awful thing will end
And our poor earth can start to mend.
I love this. Thank you!

The mortality risk is clear now. It is not the general population. Getting a mild infection which creates protective antibodies is not a major medical problem. This is necessary to control the duration of the pandemic. It is epidemiology 101 and called Herd Immunity!

@@gypsypath1 wheres your theory behind this and wheres a video explaing long term damage to asymptomatic victims. I would be interested to watch it.
@Yogurt Slinger because it’s not a cold. There are many cases of diabetes linked to a prior COVID-19 infection and there are several reports about neurological and organ damages caused by it. I know many doctors and nurses and I‘ve heard quite some horror stories about 30 year olds with no pre-existing conditions which were close to death and totally wrecked after a COVID-19 infection (and they work in different hospitals in different parts of the country). Just because you didn’t experience it yourself or know anyone who really suffered doesn’t mean it doesn’t exist...

This video should be forced watching for all UK MP's.
Maybe then they would realise the errors of their actions.
I won't hold my breath though.
I think PHE and the UK Government were fully aware that masks massively reduced the rate of infection, it is simple science after all (we all know condoms work!). The problem is they didn’t have enough stocks for NHS staff let alone the public and they didn’t want to people to panic buy the absolute PPE from suppliers.

I wonder what the infection rate is if BOTH cages have protection? Is it even lower than if only the infected hamsters were protected? (Why we should ALL be wearing them).

Thank you ,too many in USA think a mask is tyranny ( because of extended lockdown) and are refusing to ware one. I think like Taiwan and Slovakia we should have worn them from day one, and not lockdown or just two weeks.
Because some governors behave like tyrants. Like Gretchen or commie coumo.
Make masks mandatory and stop the lockdown.
They should finally stop the lockdown and the resulting social Crysis.
Because of an extremely low level of intelligence
I wouldn't brush off aversion to masks as a fear for tyranny. There IS an actual huge downsides with masks: it hides your body language. Something in the order of 60% of communication consists of body language, and your facial expressions is a HUGE part of that. This means you can't judge what a masked person is thinking, the emotional state of that person, and even if you talk to the person, the communication is more akin to talking to a machine. This is absolutely a problem and a big reason why mask wearing should not become part of our daily lives.

@@esecallum But what rates higher - an individual's right not to wear a mask, or my right not to be infected by that individual?
This has been the most logical fact since day 1. They wore them in the Spanish flu they wore them for Sars. I think they even wore them for the black plague back in the day. China made them mandatory in Wuhan. Numerous other countries have made them mandatory for covid. In my country Australia the chief medical officer for our country said they did not work for the public and this is still the statement that exists on the national broadcaster ABC website. Also by the way there have been other studies from the past saying exactly the same as this study.
Hi Dr. Campbell! Mike from Canada 🇨🇦 What do you think about face shields instead of face masks? Thanks!
If mask wearing wasn't a hallmark of this whole plannedemic, this study would be hilarious. Seriously, the only study in support of masks involves hamsters?!!
There are studies done on healthcare workers that show that masks are not only ineffective in preventing infection but long term use is detrimental to health.

@@charleslindsey6789 Wear masks forever, this is clever.
Thank you so much for your videos giving us important factual information on this virus. Your hard work and dedication are truly appreciated🤗
I can see several problems with this experiment, though. For one, the masks weren't actually on the hamsters, they were on their cages. So the hamsters weren't actually coming into contact with the masks themselves. Of course it would be highly difficult to get masks on the hamsters in the first place because they would fight them and try to get them back off as much as they could. People often do the same thing because the masks irritate their skin around their nose and their mouth. So they are often touching and adjusting the masks with their hands and scratching the skin around their nose and mouth which studies have shown pretty much negate their effectiveness. When I've worn a mask for more than a few seconds my chin starts to itch terribly. I suspect this is because, as a man, I have facial hair growing all the time. Even after I've shaved, a few hours later I have stubble because my facial hair doesn't stop growing. So I can shave in the morning and by lunch time I have stubble. Put a mask on and my chin itches like crazy. I would have to shave every few hours to keep that from happening.
Another problem with the experiment is that the hamsters were kept in separate cages. To be more like a real world experiment they would have to take the infected hamsters out of their cage and let the uninfected hamsters in their cage for a while. This would be like infected people going into public places with masks on and then leaving and then uninfected people coming into the same public place later, which is more real world where people are touching the same surfaces in public places all the time. Masks aren't going to have any effect on that.
There was another experiment I saw a video on a few days ago that was interesting. In it the staff of several hospitals was divided into 2 groups--group one wore N95 masks while group 2 wore surgical masks. They wore these masks thru flu season last year. The group that wore N95 masks had about 8% contract the flu anyway, while the group that wore surgical masks had about 7% contract the flu anyway. This seems counter intuitive since N95 masks are supposedly better at filtering out smaller particles than surgical masks. In the video it was speculated that perhaps people touching and adjusting their masks because of skin irritation by them led to the higher infection rate by those wearing N95 masks because those masks were more secure on their faces and therefore irritated their facial skin more. I thought that they needed a control group who wore NO masks just to see if even wearing a mask made any difference. But of course hospital staff have to wear masks because of their job. But then I searched online to see what the average was for people in the US contracting the flu in an average flu season and was surprised to find one source that said on average about 8% of people in the US contract the flu every year. That's about the same percentage of people who contracted the flu wearing the masks in hospitals during flu season last year! Maybe they were subjected to a higher viral load because they worked in a hospital environment during flu season. But still. Hmmmm.
In other words, this study probably understates the effectiveness of wearing a properly fitted mask.
I hope that more people here in the U.K. do wear masks...if everyone was to wear one it would greatly reduce the spread
Not worth it.

Did anyone else notice that people who put NHS stickers up their windows and clap on Thursdays are the same people who don't wear mask, don't do social distancing and break lockdown regulations?

@David Liptrot The lockdown was to protect HNS being overwhelmed. If it wasn't so, people would have started a revolution and thrown Johnson and most ministers over the cliff. HAD the lockdown been done to protect the people, it would have started WEEKS earlier with increased testing and tracing as WHO advised... itself too late to react..
I could never understand why people in the US never bothered wearing masks years ago, when so many people caught the seasona colds and flu in winter. Even if the flu doesn't wind up killing you, who wants to be miserably sick for a couple of weeks.
Those pleated surgical masks were cheap and easy to get before this virus hit, so such a small investment could have saved people from getting ill a long time ago.
Please remember that masks with valve don't protect other people from you

If you have a forced air furnace, I would suggest you check the Acoil and plentium for molds. Then retrofit the furnace air filter system with 4 inch filter rack and a
Merv 13 filter. Then install a UV light system on the intake side and the Acoil area then the out put side. Then you have a virus,mold,and particulate filtering machine your house. That is what I did way back in February.
Most masks including FFP3 and FFP3 masks are specifically designed to protect the person wearing the mask. It may offer very little protection to others as suggested. This is due to the one way valve that allows unfiltered exhaled air out. Therefore if someone sneezes, coughs or even breathes the the positive pressure within the mask will be released into the air via the valve as this is path of least resistance. This exhaled air will not have been filtered!! Therefore more sophisticated masks such as these should be reserved for NHS staff as the priority should be that they protect themselves. I completely agree that non valved masks or home made face coverings should be worn in the community by everyone. There should be lower transmission rates than the hamster tests as both the infected and non infected persons will be wearing a mask. I just wish the UK government would wake up and encourage face coverings!!

I'm in the states. It's becoming increasingly difficult to deal with my fellow citizens on this topic. There's funny anecdotes comparing mask effectiveness to a cotton condom.
Though it's funny, people here literally don't believe it works especially when they discover it's not a respirator lol.
Thank you for keeping me sane, these factual videos from people like you are important.
The better anecdote is comparing people standing next to each other and peeing. If they're both naked, the peeing guy will get his pee all over the naked non peeing guy. If the non peeing guy is wearing pants, he'll get some pee on him but not as much, but still a lot, depending on the porousness of the pants. If the peeing guy is wearing pants, he'll have the pee mostly on him with only some pee getting outside the pants and onto the floor, but if the non peeing guy's still not wearing pants and/or socks, he might still get some on his skin but even less. Now if they're both wearing pants and/or socks, there's the least chance of pee getting on the non peeing guy and even in the slight chance, there's the least amount of pee. A crude, but very effective description...
The sad thing is, a cotton condom could probably work, it just wouldn't feel too good!
To mask or not to mask has been causing division here that is beyond common sense. Instead of looking at fact (what the science/research shows), many people I know see mask-wearing as a political/cultural issue. As a person who has immune system dysfunction, I see it as life or death. This discrepancy has caused a lot of stress between me and people I call my friends.
reality is, it appears to be not factual, but rather just a quick fix to con people & get them happily going back to work to restore the economy, thinking they're safe because of their mask when it's purely a placebo.
Hamsters with a mask attached to a cage wall over sneeze distance from their faces is NOT a valid scientific experiment on this! An experiment like that is only going to get massive coverage on all media if it's consistent with the line the government/s want told.
All mask wearing countries have seen spikes in cases weeks after containing the majority of cases & enforcing mask wearing for all, showing the masks are NOT working! The only countries that haven't seen these spikes are New Zealand & Australia, who do NOT wear masks! The exception being that Australia saw one new cluster of cases in an abattoir, where workers wear masks for hygiene reasons. Remove the masks & the clusters vanish, that's the reality!
Australia & New Zealand however are insisting people are to be tested & then stay home if they have even a sniffle. Countries like the US & UK aren't willing to encourage that, because it will impact on productivity & so they roll out this fake "wear a mask & your protected" propaganda

You need to be wearing it consistently from when you leave your home to when you get back home & on arriving home, you need to be heading straight to your bathroom/laundry, removing the mask, pulling it apart for cleaning, striping your clothes into your washing machine & then getting into the shower & fully washing your entire body, hair etc & the mask with soap & water for at least 15 minutes, then going back to any door handles, taps, washing machine controls you touched & washing & disinfecting them. If you're not doing all of that everytime you go out, you're kidding yourself to think your mask is useful
Looks like we need to mask our pet hamsters then to lower this R0. ;)

Such a simple concept for a study. Sometimes it's the simple solutions that are effective, and not overthinking the problem.
Thanks again Dr. John,
Dr Campbell, thank you so much for doing this
video. It has frustrated me so much that the UK Govt and its' scientific
advisors have almost obsessively focussed on dissuading us to not wear masks,
even telling us it could put us at more risk at some points, and even now only
"if we want to - not mandatory" when in public internal places.
I have had really positive personal success with reducing colds by wearing them in planes and public transport for months before
this outbreak happened that I have been convinced about their value also for
reducing risks. Before I would get regular colds and this often resulted in 2-3
months long exhausting coughs and it would have roll on effects to other
aspects of my health. So finding ways to stop this was very important to me for
my quality of life. Mask wearing in public transport myself has made a
significant difference to me.
And as you say, the empirical evidence is also
clear from the countries which have worn them in public and also had best
success in reducing the scale of the outbreak. I understood from a presentation
by Professor Lum as part of the UK Health and Social Care Committee expert
panel discussion the other day that in Hong Kong they also didn't really lock
down - but they had 97% of the population wearing masks by March (along with
the track and trace and quarantine) and in January they mandated all care
workers must wear masks. They did not have a single COVID infection in care homes
and not a single health worker death. Now that's really impressive.
I have seen in my own work that sometimes an
'expert' has a particular take on something and then because they say it loud
enough and they are respected, many other people start saying the same thing
and it becomes a kind of 'fact' that others are looked down upon if they
contradict. I think that is also what has probably happened here and it hasn't
helped that the WHO also didn't come out and strongly advise to wear them,
giving more justification to a government like ours to ignore the experience in
the countries which previously fought SARS.
Hopefully now that we can see how badly we have
done against these other countries, this will be revisited, but that needs the
experts advising the government to also be a bit humble about their
misjudgement... I am doubtful as to whether that will happen... although I
guess they can just say... "with the new evidence... we are now changing
our advice".. even though the evidence has been there for some time.
In case you are interested please also see this
post re some mapping we did on the UK govt guidance to care homes and the major
issues with it. We continue to be very concerned about the fact that the
government still continues to not talk about asymptomatic and pre-symptomatic
transmission (thank you also for raising this in your video) - as until it
focusses on this in its guidance to care homes the risk of spread will
continue:

What drives me crazy is that authority and experts in the West were telling people not to wear them!! It's hard to find trustworthy sources of information, but this doctor is one I do trust.
Hammy wears a mask.

Well then airlines are still a major hazard, more time is more viral load.
Can't stand wearing a mask. I get lightheaded after a while.
Are you for real?
I'd love to hear the percentage differences of handwashing.
Wait for it: Time Magazine's Hamster of The Year.
In Belgium, The Heysel palace (a hugh show hall) has repurposed their air-conditioning with adding UV lamps in the airflow.
Thanks Dr. John. Thank you for the detailed explanation on this situation. I'm here in Singapore. We were advised to wear mask in public places all the time. If caught, there's a fine for not wearing. Stay safe Dr. John.
Brilliant. Just as it should be.
You probably meant to say face mask wearing was made mandatory in Singapore. The same should apply here...by simply asking to wear one would not work as there will always be people who will feel it does not apply to them.
Edinburgh University did a fantastic study months ago and the results were fantastic!! They tested a range of different masks and fabrics and everyone showed great rates of protection. I immediately bought a small amount of masks for my family and found out how we could effectively and safely rotate them, so they could be reworn many more times than they normally would.
We were amongst the first to use them locally and worried about it simply because we were told by Government, we would be talking those masks away from frontline staff. I thought it was unlikely the seller l bought from on ebay, would be approached by my Government to supply masks for our hospitals. So we soon got over those concerns and none of us leave the house without one anymore.
Thank you Dr Campbell for all your hard work. Your research is amazing. I like how you give it to us straight.
Morning my friend hope all is well . That why i wear a mask i could not live with myself if someone died or got it from me a wish i could get tested even tho i dont have symptoms lol take care much love xxx
My Taiwanese girlfriend has been insisting I go out masked for about two months now!
What is it with old white guys and Asian women lol.
Nothing wrong with that?
Hi Kevin. Ignore the harrassers. I think it's fascinating how things that are so obvious (benefits wearing masks) are looked upon with a blind eye, when the (outdated) social norms say to do otherwise. I also think the early recommendations to not wear mask were to conserve masks for hospital workers, prevent hoarding, and (sadly) to allow facial recognition software to keep working. one also can't ignore the outdated social stigma against masks that sadly seems to exist. peace, carol
Aspergers versus Neurotypicals mine was a simple joke. I’m not harassing anyone.
@David Liptrot Same, means people don't fancy kidnapping me XD If you're happy, you're happy.
19:04 SUGGESTIONS!!
"If you Care, wear!"
"Wear to Care"
"Don't Spread it / Don't Catch it!"
"Let's face it! ...together!"
You choose Dr Campbell...or maybe find even better one!! All good! ;D
kekkkee!
This needs to apply forever. Flu viruses can kill too.
*unfortunately, politicians and scientists are not on the same page vis à vis Covid- 19 prevention: the lack and the shortage of masks make false policies* .
