Advice on the use of masks in the context of COVID-19 – WHO

Transmission:

According to the current evidence, COVID-19 virus is primarily transmitted between people via respiratory droplets and contact routes. Droplet transmission occurs when a person is in close contact (within 1 metre) with an infected person and exposure to potentially infective respiratory droplets occurs.

N95 vs medical masks:

Meta-analyses in systematic literature reviews have reported that the use of N95 respirators compared with the use of medical masks is not associated with any statistically significant lower risk of the clinical respiratory illness outcomes or laboratory-confirmed influenza or viral infections.

Wearing masks by the general public:

There is limited evidence that wearing a medical mask by healthy individuals in households, in particular those who share a house with a sick person, or among attendees of mass gatherings may be beneficial as a measure preventing transmission.

At present, there is no direct evidence (from studies on COVID-19 and in healthy people in the community) on the effectiveness of universal masking of healthy people in the community to prevent infection with respiratory viruses, including COVID-19.

At the present time, the widespread use of masks by healthy people in the community setting is not yet supported by high quality or direct scientific evidence and there are potential benefits and harms to consider.

Interim Guidance for the Use of Masks to Control Seasonal Influenza Virus Transmission – CDC

Persons who are diagnosed with influenza…should remain at home until the fever is resolved for 24 hours…and the cough is resolving to avoid exposing other members of the public. If such symptomatic persons cannot stay home during the acute phase of their illness, consideration should be given to having them wear a mask in public places when they may have close contact with other persons. 

No recommendation can be made at this time for mask use in the community by asymptomatic persons, including those at high risk for complications, to prevent exposure to influenza viruses.

Can surgical masks protect you from getting the flu? – Medical Xpress (2019)

The study, published in JAMA, found that surgical masks were as effective as N95 respirators at preventing the flu, which is to say, not all that effective because, of the 446 nurses who took part in this study, nearly one in four (24%) in the surgical mask group still got the flu as did 23% of those who wore the N95 respirator. And, because both groups wore masks, it’s impossible to say how they would have fared compared with not wearing a mask at all.

Basically, there is no strong evidence to support well people wearing surgical masks in public. Or as the US Centers for Disease Control and Prevention put it: “No recommendation can be made at this time for mask use in the community by asymptomatic persons, including those at high risk for complications, to prevent exposure to influenza viruses.”

The best thing you can do to stop getting the flu is to regularly wash your hands, and try to avoid touching your face.

Limited evidence regarding the respiratory protection using non-medical / homemade masks – SAGE

SARS-CoV-2 in the hospital environment and risk of COVID-19 nosocomial transmission

A document produced by SAGE states the following.

Evidence on efficacy of cloth face-coverings (non-medical masks):

There is limited evidence regarding the respiratory protection that non-medical / homemade masks can offer for the wearer, and there are no established quality standards for self-made face masks. One study reported a low filter efficiency (3-33%), and high penetration (up to 97%) of NaCl aerosol particles in homemade masks (42). A trial comparing the use of cloth and medical masks by healthcare workers also showed penetration of microorganisms by 97%, compared with a rate of 44% for medical masks (43).

Coronavirus: Why everyone was wrong – Dr. Beda Stadler

Professor Dr. Beda M Stadler is the former director of the Institute for Immunology at the University of Bern, a biologist and professor emeritus.

Novelty:

Sars-Cov-2 isn’t all that new, but merely a seasonal cold virus that mutated and disappears in summer, as all cold viri do — which is what we’re observing globally right now. Flu viri mutate significantly more, by the way, and nobody would ever claim that a new flu virus strain was completely novel.

Immunity:

In mid-April work was published by the group of Andreas Thiel at the Charité Berlin. A paper with 30 authors, amongst them the virologist Christian Drosten. It showed that in 34 % of people in Berlin who had never been in contact with the Sars-CoV-2 virus showed nonetheless T-cell immunity against it (T-cell immunity is a different kind of immune reaction, see below). This means that our T-cells, i.e. white blood cells, detect common structures appearing on Sars-CoV-2 and regular cold viri and therefore combat both of them.

…almost no children under ten years old got sick, everyone should have made the argument that children clearly have to be immune. For every other disease that doesn’t afflict a certain group of people, we would come to the conclusion that that group is immune. When people are sadly dying in a retirement home, but in the same place other pensioners with the same risk factors are left entirely unharmed, we should also conclude that they were presumably immune.

Modelling:

Epidemiologist also fell for the myth that there was no immunity in the population. They also didn’t want to believe that coronaviri were seasonal cold viri that would disappear in summer. Otherwise their curve models would have looked differently. When the initial worst case scenarios didn’t come true anywhere, some now still cling to models predicting a second wave.

Asymptomatic transmission:

The term “silent carriers” was conjured out of a hat and it was claimed that one could be sick without having symptoms.

The next joke that some virologists shared was the claim that those who were sick without symptoms could still spread the virus to other people…But for doctors and virologists to twist this into a story of “healthy” sick people, which stokes panic and was often given as a reason for stricter lockdown measures, just shows how bad the joke really is. At least the WHO didn’t accept the claim of asymptomatic infections and even challenges this claim on its website.

Testing:

So if we do a PCR corona test on an immune person, it is not a virus that is detected, but a small shattered part of the viral genome. The test comes back positive for as long as there are tiny shattered parts of the virus left. Correct: Even if the infectious viri are long dead, a corona test can come back positive, because the PCR method multiplies even a tiny fraction of the viral genetic material enough [to be detected]…The crux was that the virus debris registered with the overly sensitive test and therefore came back as “positive”. It is likely that a large number of the daily reported infection numbers are purely due to viral debris.

Kawasaki Syndrome:

If an infected person does not have enough antibodies, i.e. a weak immune response, the virus slowly spreads out across the entire body. Now that there are not enough antibodies, there is only the second, supporting leg of our immune response left: The T-cells beginn to attack the virus-infested cells all over the body. This can lead to an exaggerated immune response, basically to a massive slaughter; this is called a Cytokine Storm. Very rarely this can also happen in small children, in that case called Kawasaki Syndrome. This very rare occurrence in children was also used in our country to stoke panic. It’s interesting, however, that this syndrome is very easily cured. The [affected] children get antibodies from healthy blood donors, i.e. people who went through coronavirus colds.

Second Wave:

The virus is gone for now. It will probably come back in winter, but it won’t be a second wave, but just a cold.

Face masks:

Those young and healthy people who currently walk around with a mask on their faces would be better off wearing a helmet instead, because the risk of something falling on their head is greater than that of getting a serious case of Covid-19.

Lethality:

People below 65 years old make up only 0.6 to 2.6 % of all fatal Covid cases. To get on top of the pandemic, we need a strategy merely concentrating on the protection of at-risk people over 65.

Visualizing the effectiveness of face masks in obstructing respiratory jets – AIP Publishing

The use of face masks in public settings has been widely recommended by public health officials during the current COVID-19 pandemic. The masks help mitigate the risk of cross-infection via respiratory droplets; however, there are no specific guidelines on mask materials and designs that are most effective in minimizing droplet dispersal. While there have been prior studies on the performance of medical-grade masks, there are insufficient data on cloth-based coverings, which are being used by a vast majority of the general public. We use qualitative visualizations of emulated coughs and sneezes to examine how material- and design-choices impact the extent to which droplet-laden respiratory jets are blocked. Loosely folded face masks and bandana-style coverings provide minimal stopping-capability for the smallest aerosolized respiratory droplets. Well-fitted homemade masks with multiple layers of quilting fabric, and off-the-shelf cone style masks, proved to be the most effective in reducing droplet dispersal. These masks were able to curtail the speed and range of the respiratory jets significantly, albeit with some leakage through the mask material and from small gaps along the edges. Importantly, uncovered emulated coughs were able to travel notably farther than the currently recommended 6-ft distancing guideline. We outline the procedure for setting up simple visualization experiments using easily available materials, which may help healthcare professionals, medical researchers, and manufacturers in assessing the effectiveness of face masks and other personal protective equipment qualitatively.

HM Government guidance states evidence for face coverings is weak

Working safely during COVID-19 in offices and contact centres, published 24 June 2020, states:

6. Personal Protective Equipment (PPE) and face coverings
Unless you are in a situation where the risk of COVID-19 transmission is very high, your risk assessment should reflect the fact that the role of PPE in providing additional protection is extremely limited.

6.1 Face coverings
There are some circumstances when wearing a face covering may
be marginally beneficial as a precautionary measure. The evidence
suggests that wearing a face covering does not protect you, but it
may protect others if you are infected but have not developed
symptoms.

It is important to know that the evidence of the benefit of using a face covering to protect others is weak and the effect is likely to be small…

Why Face Masks Don’t Work: A Revealing Review – John Hardie, PhD, Oral Health Group (2016)

The primary reason for mandating the wearing of face masks is to protect dental personnel from airborne pathogens. This review has established that face masks are incapable of providing such a level of protection. Unless the Centers for Disease Control and Prevention, national and provincial dental associations and regulatory agencies publically admit this fact, they will be guilty of perpetuating a myth which will be a disservice to the dental profession and its patients. It would be beneficial if, as a consequence of the review, all present infection control recommendations were subjected to the same rigorous testing as any new clinical intervention. Professional associations and governing bodies must ensure the clinical efficacy of quality improvement procedures prior to them being mandated. It is heartening to know that such a trend is gaining a momentum which might reveal the inadequacies of other long held dental infection control assumptions. Surely, the hallmark of a mature profession is one which permits new evidence to trump established beliefs. In 1910, Dr. C. Chapin, a public health pioneer, summarized this idea by stating, “We should not be ashamed to change our methods; rather, we should be ashamed not to do so.” 36 Until this occurs, as this review has revealed, dentists have nothing to fear by unmasking.

Surgical masks as source of bacterial contamination during operative procedures – Science Direct (2018)

The source of bacterial contamination in SMs was the body surface of the surgeons rather than the OR environment. Moreover, we recommend that surgeons should change the mask after each operation, especially those beyond 2 hours. Double-layered SMs or those with excellent filtration function may also be a better alternative.

Coronavirus: Face masks could increase risk of infection, medical chief warns – Independent

Members of the public could be putting themselves more at risk from contracting coronavirus by wearing face masks, one of England’s most senior doctors has warned.

Jenny Harries, deputy chief medical officer, said the masks could “actually trap the virus” and cause the person wearing it to breathe it in.

“For the average member of the public walking down a street, it is not a good idea” to wear a face mask in the hope of preventing infection, she added.

 Jake Dunning, head of emerging infections and zoonoses [infectious disease spread between humans and animals] at Public Health England, told The Independent there was “very little evidence of a widespread benefit” from wearing them.

A cluster randomised trial of cloth masks compared with medical masks in healthcare workers – BMJ (2015)

Penetration of cloth masks by particles was almost 97% and medical masks 44%.

This study is the first RCT of cloth masks, and the results caution against the use of cloth masks. This is an important finding to inform occupational health and safety. Moisture retention, reuse of cloth masks and poor filtration may result in increased risk of infection. Further research is needed to inform the widespread use of cloth masks globally. However, as a precautionary measure, cloth masks should not be recommended for HCWs, particularly in high-risk situations, and guidelines need to be updated.

Tell MPs ‘not in my name’ if you are horrified by this social experiment – The Telegraph

Are we going to stand for the pathological coercion of our nation – or finally start organising against it?

Many people who lived through the last war – or whose parents have vivid recollections of it – will tell you that they are infuriated by any suggestion that our present emergency is anywhere near comparable to that experience. We are not descending into bomb shelters at night, emerging in the morning possibly to find our homes and family possessions destroyed. The deprivations that we are enduring today are relatively trivial: locked in, as most of us are, with our myriad electronic devices and forms of entertainment which would have seemed magical to that stoical population gathered around the wireless every evening to listen to whatever the government permitted the BBC to offer.

Professor Dolores Cahill on The James Delingpole Channel

Professor Dolores Cahill from James Delingpole on Vimeo.

James talks with Professor Dolores Cahill, a world renowned immunologist who has advised the Irish government and the EU.

  • We should end the lockdown. Quarantining healthy people was a huge mistake, should never have been done and should never happen again.
  • All the available information tells us there’s no longer any basis for the lockdowns. The economic harm and resulting health effects could be five times higher than those caused by the virus. The adverse health implications of poverty is well-known and has lots of supporting data.
  • The immunology community knew in January and February that there was nothing very special about COVID-19.
  • There are lots of clinical trials showing the usefulness of vitamins C, D and Zinc for preventing symptoms of corona-type viruses.
  • It is also very well established that hydroxychloroquine, which is a very safe drug, can be used as a treatment.
  • There was no need to ramp up the hospital care system because there were established methods for prevention and treatment.
  • It was known that the virus would circulate the world in a month. Professor Cahill was surprised at the lockdown because the ‘virus was gone.’ There is clearly enough data for this.
  • COVID-19 (also known as SARS-CoV-2) is about 80% the same as SARS-CoV-1 in 2003. These types of viruses last about 6 weeks in each location before naturally ‘dying off’ as people become exposed and then developing immunity.
  • 80 out of 100 people would have developed antibodies within 10-11 days and become immune for life without experiencing symptoms.
  • Although COVID-19 is a novel virus, it can be ‘recognized’ by the immune system of anyone who had already been exposed to SARS-CoV-1. This is because of COVID-19’s 80% similarity to the earlier 2003 virus.
  • With these types of viruses, you will be negative for the PCR test (which tests for the presence of the virus) after recovery but you will test positive for the antibodies.
  • You don’t need the lockdown if you boost your immune system. in fact, the lockdown made matters worse by depressing people’s immune system. Sunshine, interacting with people, shaking hands–all these help to boost your immune system.
  • Elderly people should be taking vitamin C, D and Zinc to protect their immune systems. People with underlying conditions, or those who develop symptoms, should contact their doctor to consider prescribing off-label hydroxychloroquine.
  • Symptoms: flu-like for the first five days. If it gets worse and you develop a cough, that’s when you need to ring your doctor for treatment. Treatment includes hydroxychloroquine for 3-5 days, with Zinc and AZT antibiotic. This is an established protocol that has been used in many clinical trials in 2020.
  • There was some reason to be scared of COVID-19 during the very early stages (around January) because because we didn’t know anything about it. However, the media and WHO was fearmongering when they used Wuhan as an example of what would happen everywhere.
  • From February onward, the immunology community recognized that COVID-19 is the same as a normal virus in most parts of the world. There was something different about Wuhan, Bergamo and New York but t here was no reason to lockdown the rest of the world.
  • Vaccines have their place and can be safe. However, studies show that animal and human subjects that were given a type of influenza vaccine later reacted badly when they encountered a coronavirus ‘in the wild’. The reaction caused a cytokine storm that either killed the subject or made the subject very ill. The reaction between different types of vaccinated and wild viruses is called viral interference.
  • People in Wuhan and Bergamo were given a certain type of influenza vaccine. It became apparent around April-May that the high death rates in both cities could be due to viral interference from the administered influenza vaccine.
  • It has not been possible to make a safe and effective vaccine for the SARS-CoV-1 in 2003. If we have not been able to make a vaccine for this coronavirus, we should not expect a safe vaccine for COVID-19 any time soon. A vaccine developed for COVID-19 would be a complete experiment on those who take it.
  • Vaccines containing alluminium, Thimerodal or mercury are intrinsically unsafe.
  • The global death rate for COVID-19 is around the same as a bad influenza. Outside of Wuhan, Bergamo and New York, the death rate appears to be less than the normal flu.
  • Current data shows that the real death rate for COVID-19 is 20 or 30 times less than the initial estimates from the WHO. We now know the death rate is about one in a thousand for the vulnerable and one in five thousand for the healthy. In the under 70s age range, this is lower than the average flu.
  • It was well-known in February that there was no need for the lockdowns.
  • There have been no cases of transmission from children.
  • If we were to end the lockdown, we would need 10 days to prepare. This is because people have not been out and exposed to sunlight. Preparation include taking vitamins C, D and Zinc; getting fresh air; avoiding stress; and making sure doctors have hydroxychloroquine.
  • It is almost as if the current advice is geared to making sure people get sick in order to support more lockdowns.
  • There will be no second spike if people take the above precautions to strengthen their immune system.
  • A recent study shows that people who continued working were healthy. Engaging with other keeps you healthy by strengthening the immune system.
  • There hasn’t been an open debate in any country about the harm versus benefits of the lockdown. This may be a big reason for why the lockdowns are continuing.
  • Dr. Rashid A. Buttar and Dr. Judy Mikovits are trying to open the debate about prevention and treatments but their voices are being censored.
  • The use of hydroxychloroquine as a treatment has been politicized.
  • Evidence is being cherry-picked in order reach a predetermined goal: a money-making vaccine. The existing prevention and treatment methods don’t make money for big-pharma.
  • Masks and social distancing is appropriate for something like ebola but not for coronaviruses.
  • We will build up herd immunity within about two weeks.
  • We know how COVID-19 is transmitted because it belongs to the family of coronaviruses. It is not transmitted through the air. This has been proven because groups of people in encloses spaces (for example, plane-loads of fruit-pickers) did not all come down with the sickness.
  • The two meter rule is unnecessary.
  • There was enough information from many sources for the government and their advisors to know that all these measures are wrong. There should be legal implications for those who advocate continued lockdown. Hundreds of unnecessary deaths should be grounds for a legal tribunal.
  • There is a high risk of a death spike after lockdown due to other causes, such as cancers, that will attributed to COVID-19. This will be used to support more lockdowns.
  • The politicians, broadcasters, newspaper editors, ministers for health–everyone complicit in censoring and withholding information from the public about the true nature of COVID-19 needs to be held personally liable for the deaths caused.

Masks Don’t Work: A review of science relevant to COVID-19 social policy – ResearchGate

Masks and respirators do not work. There have been extensive randomized controlled trial (RCT) studies, and meta-analysis reviews of RCT studies, which all show that masks and respirators do not work to prevent respiratory influenza-like illnesses, or respiratory illnesses believed to be transmitted by droplets and aerosol particles. Furthermore, the relevant known physics and biology, which I review, are such that masks and respirators should not work. It would be a paradox if masks and respirators worked, given what we know about viral respiratory diseases: The main transmission path is long-residence-time aerosol particles (< 2.5 μm), which are too fine to be blocked, and the minimum-infective-dose is smaller than one aerosol particle. The present paper about masks illustrates the degree to which governments, the mainstream media, and institutional propagandists can decide to operate in a science vacuum, or select only incomplete science that serves their interests. Such recklessness is also certainly the case with the current global lockdown of over 1 billion people, an unprecedented experiment in medical and political history.

LOCKDOWN LUNACY: the thinking person’s guide

  • Fact #1: The Infection Fatality Rate for COVID-19 is somewhere between 0.07-0.20%, in line with seasonal flu
  • Fact #2: The risk of dying from COVID-19 is much higher than the average IFR for older people and those with co-morbidities, and much lower than the average IFR for younger healthy people, and nearing zero for children
  • Fact #3: People infected with COVID-19 who are asymptomatic (which is most people) do NOT spread COVID-19
  • Fact #4: Emerging science shows no spread of COVID-19 in the community (shopping, restaurants, barbers, etc.)
  • Fact #5: Published science shows COVID-19 is NOT spread outdoors
  • Fact #6: Science shows masks are ineffective to halt the spread of COVID-19, and The WHO recommends they should only be worn by healthy people if treating or living with someone with a COVID-19 infection
  • Fact #7: There’s no science to support the magic of a six-foot barrier
  • Fact #8: The idea of locking down an entire society had never been done and has no supportable science, only theoretical modeling
  • Fact #9: The epidemic models of COVID-19 have been disastrously wrong, and both the people and the practice of modeling has a terrible history
  • Fact #10: The data shows that lockdowns have NOT had an impact on the course of the disease.
  • Fact #11: Florida locked down late, opened early, and is doing fine, despite predictions of doom
  • Fact #12: New York’s above average death rate appears to be driven by a fatal policy error combined with aggressive intubations.
  • Fact #13: Public health officials and disease epidemiologists do NOT consider the other negative societal consequences of lockdowns
  • Fact #14: There is a predictive model for the viral arc of COVID-19, it’s called Farr’s Law, and it was discovered over 100 years ago
  • Fact #15: The lockdowns will cause more death and destruction than COVID-19 ever did
  • Fact #16: All these phased re-openings are utter nonsense with no science to support them, but they will all be declared a success

Face Mask Use and Control of Respiratory Virus Transmission in Households – NCBI (2009)

The key findings are that <50% of participants were adherent with mask use and that the intention-to-treat analysis showed no difference between arms. Although our study suggests that community use of face masks is unlikely to be an effective control policy for seasonal respiratory diseases, adherent mask users had a significant reduction in the risk for clinical infection. Another recent study that examined the use of surgical masks and handwashing for the prevention of influenza transmission also found no significant difference between the intervention arms.

Professor Karol Sikora: fear is more deadly than the virus – UnHerd

  • Professor Karol Sikora says that COVID-19 behaves like pandemics in the past.
  • Society is scarred all over the world.
  • The virus will go but the fear will do the damage.

Note: YouTube has taken down the video. Please go directly to UnHerd’s site:

https://unherd.com/thepost/professor-karol-sikora-fear-is-more-dangerous-than-the-virus/

Professor Karol Sikora has become something of a celebrity in the UK over the past months for his expert commentary on the pandemic, and his unusual tendency for optimism rather than pessimism.

Virus ‘getting tired’
– In the past two weeks, the virus is showing signs of petering out
– It’s as though the virus is ‘getting tired’, almost ‘getting bored’
– It’s happening across the world at the same time

Existing herd immunity
– The serology results around the world (and forthcoming in Britain) don’t necessarily reveal the percentage of people who have had the disease
– He estimates 25-30% of the UK population has had Covid-19, and higher in the group that is most susceptible
– Pockets of herd immunity help *already* explain the downturn
– Sweden’s end result will not be different to ours – lockdown versus no lockdown

Fear more deadly than the virus
– When the history books are written, the fear will have killed many more people than the virus, including large numbers of cancer and cardiological patients not being treated
– We should have got the machinery of the NHS for non-corona patients back open earlier

Masks and schools
– Evidence on masks is just not there either way so it should be an ‘individual decision’
– We should move to 1m social distancing which means restaurants and bars could reopen
– More schools should reopen in June as ‘children are not the transmitters of this virus’
– We should be getting back to the ‘old normal’ not a ‘new normal’

Why is Sweden not recommending face masks to the public?

Face masks in public spaces do not provide any greater protection to the population,” Johan Carlson from the Swedish Public Health Agency Folkhälsomyndigheten said at a press conference on May 13th.

Swedish health authorities argue that keeping a distance, washing your hands, not touching your face, and staying at home if you experience any symptoms are still the best ways to halt the spread of the coronavirus. There is a concern that wearing face masks would make people follow these guidelines less strictly.

  • There is a risk of a false sense of security.
  • The virus can gather in the mask and when you take it off, the virus can be transferred to your hands and thereby spread further.
  • Worn properly, masks might reduce the spread of infection if worn by those with asymptomatic infections, even if they might not protect the wearer themselves.

Face Masks Pose Serious Risks To The Healthy – Russell Blaylock MD

As for the scientific support for the use of face mask, a recent careful examination of the literature, in which 17 of the best studies were analyzed, concluded that, “ None of the studies established a conclusive relationship between mask/respirator use and protection against influenza infection.”1

When a person is infected with a respiratory virus, they will expel some of the virus with each breath. If they are wearing a mask, especially an N95 mask or other tightly fitting mask, they will be constantly rebreathing the viruses, raising the concentration of the virus in the lungs and the nasal passages. We know that people who have the worst reactions to the coronavirus have the highest concentrations of the virus early on. And this leads to the deadly cytokine storm in a selected number.

Surgical Mask vs N95 Respirator for Preventing Influenza Among Health Care Workers – JAMA (2009)

Surgical masks and N95 respirators are not effective at preventing the flu. Of the 446 nurses who took part in this study, nearly one in four (24%) in the surgical mask group still got the flu as did 23% of those who wore the N95 respirator.

Influenza infection occurred in 50 nurses (23.6%) in the surgical mask group and in 48 (22.9%) in the N95 respirator group (absolute risk difference, −0.73%; 95% CI, −8.8% to 7.3%; P = .86), the lower confidence limit being inside the noninferiority limit of −9%.
