This video is from Dr Mike Hansen's excellent medical channel, June 16, 2020. Dr Hansen works in Emergency Medicine as a pulmonary specialist and has made a number of highly informative videos on the subject of covid 19.
Transcript for the above video, originally entitled, "Does Blood Type Matter for Coronavirus (COVID-19)?."
People have either blood type A, B, AB, or O.
Are people with blood type O less prone to suffer from COVID-19? And does blood type A make people more prone to COVID-19?
Let me first start out by saying that people of all blood types can get COVID. And people with all blood types can possibly die of COVID if they get the infection.
But, based on several different studies, it looks like people with blood type O have less a chance of getting COVID-19, and people with type A might have a higher chance of getting the infection.
Data from China was the first to show the ABO blood group association with COVID-19 infections.
The researcher Zhao and others compared ABO blood groups of controls from the general population with over 2100 COVID patients from three hospitals in Wuhan.
Across all three hospitals, blood group A was associated with a higher risk for COVID compared with non-A blood groups, whereas blood group O was associated with a significantly lower risk for infection compared with non-O blood groups.
There was another observational study on data from the New York-Presbyterian hospital system, which happens to be where I did my fellowship training. So there, over 1500 people tested for COVID, and they had similar results with blood types.
There was another study done by Andre Franke in Italy and Spain.
In this study, they looked at DNA samples from 1,980 COVID-19 patients who were hospitalized for respiratory failure. And the study produced similar results.
But what about the severity of illness?
Does having blood type O, make someone less likely to have a severe illness from COVID, compared to type B, type AB, and type A?
Well, Zhao and others looked at the case fatality rate, and blood group A was linked to higher mortality risk compared to blood group O.
Interestingly, the association of blood type is not explainable by other risk factors, like obesity, diabetes, and high blood pressure.
Recently, there was a study published by the personal genetics company 23andMe regarding evidence that blood type plays a role in COVID-19.
So if you don’t know, 23andMe is a company that sends out personal genetics testing kits to individuals who are interested in finding out their genetic history and or their predisposition to certain genetically transmitted diseases.
According to their website, they did a study based on over 750,000 people.
Their preliminary results suggest that O blood type appears to be slightly less susceptible to contracting the virus.
But the big question is why?
No one really knows, but there are a lot of hypotheses.
BLOOD TYPE is determined by genetics, and the genes determine the specific proteins on the surface of the cell. These proteins, then have specific sugar molecules that are added to them. They exist in our blood cells and other cell types.
People who are blood type A carry A-sugar-antigens
People who are blood type B carry B-sugar-antigens
People with O blood type have neither A nor B-sugar antigens.
What is the significance of this?
This means that the immune systems of people with type A blood develop antibodies for B antigens.
People with type B blood type have antibodies for A antigens.
People with type O blood have antibodies for both A and B antigens.
People with AB blood type will have neither anti-A nor anti-B antibodies.
And here is an interesting fact we knew before COVID.
There are studies showing that people with type O blood have lower levels of proteins that promote blood clotting.
More specifically, people with blood group O have about 25% lower levels of von Willebrand factor (VWF) than those with types A, B, or AB. This is due to increased clearance of VWF from the circulation.
VWF is always involved in the development of clots, so if there is less VWF, there’s likely to be less clotting. So this might explain why Type O blood type means fewer blood clots, and this might at least partially explain why people with Type O overall have less severe disease. Because as you probably know already, lots of people with COVID pneumonia also have blood clots. Also, we know that the SARS-CoV-2 can replicate in cells that express blood type antigens. Such as the cells that form the lining of our lungs, and the cells that form our tiny little air sacs, the alveoli. And the cells that line the inside of our mouth and nasal passageways. This means that when an infected person coughs or sneezes, there's a possibility that they release viral particles that are coated with their blood type antigens. So this is at least a theory from some scientists.
We republish an article from Global Research and an excerpt from the World Health Organisation on this politically, commercially, and thus medically, fraught topic. The World Health Organisation's ongoing research project page on Electromagnetic fields (EMF) is at https://www.who.int/peh-emf/project/EMF_Project/en/. Not mentioned in the Global Research article below is the World Health Organisation's report that "studies suggest that children exposed to EMF magnetic fields have an associated increased risk of leukaemia." The Global Research article below the WHO introduction is useful because it gives a number of strategies for minimising exposure to EMF, particularly where children are concerned. Furthermore, it gives access to opinion from different countries. We should remember that X-Rays were not banned for pregnant women until the mid-1980s, a long time after it was well-known that they were the major cause of childhood cancers. (See Margaret Heffernan, Wilful Blindness.) A much more intensive and pervasive level of electromagnetic fields involved in 5G and "smart cities" is being introduced to Australia and many countries as we write this. Smart cities carry their own dangers of total surveillance and automation that seem calculated to remove almost all possibility of democratic engagement, although that is not the subject of the reports cited below. (See Prof Justin O'Connor in "Smart Cities vs Creative Cities Symposium".)
World Health Organisation: "What is the International EMF Project? - Introduction
Potential health effects of exposure to static and time varying electric and magnetic fields need scientific clarification. Electromagnetic fields of all frequencies represent one of the most common and fastest growing environmental influences, about which there is anxiety and speculation are spreading. EMF exposure now occurs to varying degrees to all populations of the world, and the levels will continue to increase with advancing technology. Thus, even a small health consequence from EMF exposure could have a major public health impact.
Concerns have been expressed that exposure to extremely low frequency (ELF) magnetic fields at power frequencies (50/60 Hz) could lead to an increased incidence of cancer in children and other adverse health effects. The evidence comes primarily from residential epidemiological studies. These studies suggest that children exposed to ELF magnetic fields have an associated increased risk of leukaemia.
Radio frequency (RF) fields are used to great benefits in many facets of everyday life, such as radio and TV transmission, telecommunications (eg mobile telephones), diagnosis and treatments of disease and in industry for heating and sealing materials. With the rapid introduction of mobile telecommunications devices, especially among the general public, there has been a focus on the problems associated with near field RF exposure to the head from the small radiating antenna of mobile phones. In addition, concerns persist that exposure to pulsed and amplitude modulated RF fields may cause specific health effects.
As societies develop, greater use of certain technologies leads to increasing exposure to static electric and magnetic fields. This is especially the case in industry, transport, power transmission, research and medicine. Possible health effects from static fields have never been properly assessed. Given the rapid expansion of medical devices and imminent introduction, potentially on a large scale, of magnetic levitation transport systems that use strong static magnetic fields, any health impacts need to be properly assessed.
As part of its charter to protect public health and in response to public concern over health effects of EMF exposure, the World Health Organization (WHO) established the International EMF Project in 1996 to assess the scientific evidence of possible health effects of EMF in the frequency range from 0 to 300 GHz. The EMF Project encourages focused research to fill important gaps in knowledge and to facilitate the development of internationally acceptable standards limiting EMF exposure."
1. All Cell Phones And Wireless Devices Emit Radiation.
Every wireless device is actually a two-way microwave radio that sends and receives a type of non-ionizing electromagnetic radiation called radio frequency radiation RF – EMF. This machine-made radiation is millions of times higher than the natural electromagnetic fields (EMFs) our grandparents were exposed to. Numerous peer reviewed published research studies shows that these made-made pulsed electromagnetic frequencies cause adverse biological effects and are very different than the natural electromagnetic fields that have existed in the environment for years. Research on humans has found an association between cell phone use and serious effects such as brain cancer, headaches, damage to the brain and immune system. Yale studies found that cellular radiation exposure during pregnancy led to increased hyperactivity and memory problems in offspring.
2. Our Brains And Bodies Are Penetrated By This Radiation.
When we hold a cell phone against our head to talk, the radiation from the phone moves into our brain. Likewise, when we use a wireless laptop, the radiation penetrates into our abdominal region, chest area and brain.According to the International Agency for the Research on Cancer:
“the average radio frequency radiation energy deposition for children exposed to mobile phone RF is two times higher in the brain and 10 times higher in the bone marrow of the skull, compared with mobile phone use by adults”.
Research also has found that radiation from tablets penetrates more deeply into children’s brains (Ferreira 2015.) A 2018 study that considered the radiation dose into the brain of teenagers found that teens who used cell phones up to their head had decreased memory performance on researchers tests.
3. Cell Phones And Wireless Devices Emit Radiation Constantly, Even When You Are Not Talking Or Using The Phone.
A powered on cell phone is always “checking in” and maintaining a connection to the nearest cell tower by sends intense bursts of radiation several times per second. Likewise, a wireless-enabled laptop, tablet or other device is always “checking in” with the nearby router or a network base. These “check ins” are radiation emissions—happening several times per second, and whether or not a connection is successfully established.Medical doctors have written many letters to schools calling for administrators to reduce exposures to this radiation in schools. Harvard doctors have published research linking electromagnetic fields to autism.
4. Every Wireless Device Has Fine Print Instructions Buried In Its User Manual That Specify A Distance Between The Device And User That Should Not Be Surpassed.
For example, most cell phone manuals state the phone should be held at specified distance (often around 5/8th of an inch) from the body. If you look in the user manual for your DECT cordless home phone, wireless laptop or printer, it will state that the device should be at least 20 cm (approximately 8 inches) away from the body to prevent “exceeding FCC radiation exposure limits”. These instructions are in the user manuals because cell phones and wireless devices are tested for user radiation exposures at those specific distances.
In other words, if you are using a laptop on your lap, you are exposing yourself to untested radiation emissions that could exceed the radiation levels our government regulations presently allow. When you use a device closer than the manufacturer’s distance instructions, you risk exposing yourself to radiation levels that our federal government understands can cause sterility, brain damage and tissue damage. Learn more about the fine print warnings on various devices here.
5. These Fine Print Instructions DO NOT Protect You From All Health Effects.
The instructions buried in your manual are not safe enough. Even if you follow these instructions, you risk your health. Note: radiation exposure at the specified distances is much higher than zero. Accumulating research now shows a myriad of health effects occur at levels far far below (literally tens of thousands times lower than) government regulation limits. Wireless devices were not adequately tested before they came on the market.
6. Research Shows Low Levels Of This Radiation Impact The Brain And Reproductive System.
Wireless radiation has been shown to change brain function even at levels hundreds of thousands of times below federal guidelines. In 2011, Dr. Volkow’s NIH research showed that the brain increased glucose metabolism when exposed to cell phone radiation. Dr. Suleyman Kaplan has published multiple research studies showing damaged brain development in the offspring of prenatally exposed test subjects. Significant research shows that wireless exposures decrease and damage sperm and that prenatal exposure can alter testis and ovarian development. These are just a few examples from a large body of accumulated science which shows effects from cell phone and wireless radiation.
7. Radiation Emitted By Cell Phones And Wireless Is Officially Linked To Cancer.
In 2011, the World Health Organization’s International Agency for Research on Cancer first classified cell phone and wireless radiation as a “class 2 B Possible Human Carcinogen” based on these research studies that showed long-term users of cell phones had higher rates of brain cancer on the side of the head where they held the phone.The United States National Toxicology Program completed a $30M study that found “clear evidence” of cancer in male rats exposed to long term low level radio-frequency radiation. Due to these findings, several scientists have published that the weight of current peer reviewed evidence supports the conclusion that radiofrequency radiation should be regarded as a human carcinogen.
8. As The Evidence Linking Wireless Radiation To Cancer Has Significantly Increased Since 2011, Now Scientists State That Cell Phone Wireless Radiation Is A Human Carcinogen.
In 2016, a major US government study found cell phone radiation caused increased cancers (brain and heart nerve) in rats exposed at low levels for two years. The results were stunning because the cancers the rats developed are the same type humans are developing after long term cell phone use.
Furthermore, since 2011, new research studies have been published linking wireless radiation to cancer. CERENAT (a case control national study in France) again showed a statistically significant association between glioma (brain cancer) and long-erm cell phone use. Another study out of Jacobs University (which replicated previous study results) showed that RF acted as a tumor promoter. The study details in its conclusion how, “Numbers of tumors of the lungs and livers in exposed animals were significantly higher than in sham-exposed controls. In addition, lymphomas were also found to be significantly elevated by exposure.”
In light of this published science, several World Health Organization experts are stating that the evidence has now substantially increased. Dr. Anthony B. Miller has testified on the increased evidence, and he and colleagues have written several published papers detailing their opinion and in 2018 he was lead author on a published literature review concluding that cell phone wireless radiation is a human carcinogen. Scientists from Israel researching cancr in radar operators also concluded that the evidence indicates radiofrequency can cause cancer (Peleg 2018.) Dr. Hardell and colleagues have long published papers concluding that that wireless “should be regarded as human carcinogen requiring urgent revision of current exposure guidelines.”
9. Solutions Exist: Hundreds Of Scientists Worldwide Recommend Taking Action To Reduce Exposures To Wireless Devices Because Of The Serious Health Effects From These Devices.
In 2015, a large group of scientists and medical doctors signed onto a formal Appeal to the United Nations and the World Health Organization, calling on them to take immediate action on this issue. This Appeal is now signed by over 250 experts and is published in the International Journal of Oncology.In 2014, a group of U.S. physicians, including the Chief of Obstetrics at Yale Medicine, presented scientific studies at the launch of the BabySafe Project, issuing specific recommendations to pregnant women on how to decrease wireless exposures in order to decrease risks to babies’ brain development. We do not have to give up our technology but we can make smarter choices about the way we use it. Every person can easily decrease exposure to this radiation by making simple changes every day.
10. Government Regulations Are Outdated And Antiquated.
In the United States, the last review for radio frequency limits was in 1996, and the reality is that these are limits are based on research from the 1980s. Many countries are using guidelines developed by the IEEE or ICNIRP—guidelines that have remained unchanged for decades. Those guidelines do not consider the more current science showing harm. Thankfully other countries – over twenty countries- are enacting protections to reduce public exposure to this radiation and have radiation limits far lower than the FCC and ICNIRP. Some have banned Wi-Fi in classsrooms, other have banned cell phones made for young children and others have cell tower limits 100x lower than ICNIRP.Regulations are antiquated because they have not kept pace with the manner in which consumers use devices—usage has changed considerably since 1996. For example, the regulations only consider one radiating device at a time and do not account for a residence, classroom, or workplace, healthcare, retail, recreational and other venues filled with multiple devices. The regulations do not consider that people carry their cell phones tightly in a front pocket of jeans or in a bra. They do not consider that laptops would be placed on laps by schoolchildren in the classroom. Regulations did not consider research that looked at long-term exposures to vulnerable groups such as children, pregnant women or to medically compromised individuals. Guidelines were set by only considering the impact to a full-grown man. Many scientists and major medical organizations have written about the inadequacy of these outdated guidelines.
Final Bonus Fact: No Safe Level Of This Radiation Has Been Identified.
Scientific studies have not been done to develop a “safe level” of exposure. The latest science clearly shows that biological effects could occur at non-thermal (non-heating) levels. Science also shows that children and the developing pregnancy are far more vulnerable to these damaging effects. The Food and Drug Administration (FDA) and Environmental Protection Agency (EPA) did not do the research necessary to define a safe level that the public can be exposed to without harmful effects.
In a 2015 study (replicating prior scientific findings linking RF to cancer promotion), the researchers state, “Since many of the tumor-promoting effects in our study were seen at low to moderate exposure levels (0.04 and 0.4 W/kg SAR), thus well below exposure limits for the users of mobile phones, further studies are warranted to investigate the underlying mechanisms.” and “We hypothesize that these tumor-promoting effects may be caused by metabolic changes due to exposure. Our findings may help to understand the repeatedly reported increased incidences of brain tumors in heavy users of mobile phones.”
No medical organization has determined a “safe level” of this radiation for long-term exposure to children. In fact, medical organizations worldwide – including the American Academy of Pediatrics, the largest group of children’s doctors in the United States and the Athens Medical Association and Vienna Medical Association – are calling for eliminating and reducing radiofrequency cell phone wireless radiation exposures.
