This report has been prepared by Colin Rose for Uni-Vite Healthcare to provide some answers to key questions and help in staying safe during the COVID-19 epidemic.<\/p>\n\n\n\n<p>We will explain why age is by far the biggest risk factor for a serious reaction, what can help as protection, when a vaccine may be available, how long immunity may last, and what the long term health effects are of this unprecedented threat<strong>.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Why is age <u>by far<\/u> the biggest risk factor for COVID-19?<\/strong><\/h3>\n\n\n\n<p>You\u2019ll know that most people below the age of 50 \u2013 but not all \u2013 will have mild symptoms with the new coronavirus. Above the age of 65, the risk of severe symptoms rises by 23 times! To the point that 80% of all hospitalisations are in that age category. And the fatality rate for people over 80 is 18% \u2013 almost 1 in 5.<\/p>\n\n\n\n<p>The reason is that older people generally, but not necessarily, have some or all of these increased risk factors:<\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"1\"><li>More chronic (long term) inflammation in cells, tissues and organs<\/li><li>Compromised, less effective, immune systems<\/li><li>Co-morbidities (other health conditions) like high blood pressure, cardiovascular disease, diabetes and COPD \u2013 Chronic Obstructive Pulmonary Disease. COPD is caused by a narrowing of the airways in the lungs.<\/li><li>Extra body fat \u2013 to the point where a BMI (body mass index) of over 30 (obesity) increases the risk of a severe reaction by 7 times. Even being overweight (a BMI of 28) has a 5 times increased risk. The average UK BMI is 27.5.<\/li><\/ol>\n\n\n\n<p>A key article in the Journal <em>Aging<\/em>, published end May 2020, concludes that ALL these risk factors are strongly associated with accelerated ageing \u2013 where biological ageing is running faster than chronological ageing<sup>1<\/sup>.<\/p>\n\n\n\n<p>So what helps delay ageing will also help reduce the impact of COVID-19. That will enable us to list what we believe are the most effective risk reduction actions at the end of this article.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How COVID-19 attacks<\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"587\" height=\"391\" src=\"https:\/\/www.uni-vite.com\/immunoshield\/wp-content\/uploads\/2020\/07\/covid19-pixabay.jpg\" alt=\"\" class=\"wp-image-4554\" srcset=\"https:\/\/uni-vite.com\/immunoshield\/wp-content\/uploads\/2020\/07\/covid19-pixabay.jpg 587w, https:\/\/uni-vite.com\/immunoshield\/wp-content\/uploads\/2020\/07\/covid19-pixabay-300x200.jpg 300w, https:\/\/uni-vite.com\/immunoshield\/wp-content\/uploads\/2020\/07\/covid19-pixabay-272x182.jpg 272w\" sizes=\"(max-width: 587px) 100vw, 587px\" \/><figcaption>Image by Gerd Altman courtesy of Pixabay<\/figcaption><\/figure>\n\n\n\n<p>If you look at a picture of the virus, you\u2019ll see protein spikes sticking out.<\/p>\n\n\n\n<p>On these spikes are rounded ends. At these ends is a part that docks with the receptor in human tissue called the ACE-2 receptor. It is this receptor which allows the virus to gain entry into the heart, the lungs, the lining of blood vessels and other tissues.<\/p>\n\n\n\n<p>Through this route, COVID-19 can trigger a unique constellation of symptoms, including excessive inflammation, respiratory distress, pneumonia, free radical damage, inflammatory responses leading to blood clotting, and what has been described as unusually \u2018sticky blood\u2019. &nbsp;Therefore, potentially to heart disease, stroke and neurological dysfunction.<\/p>\n\n\n\n<p>It is because COVID-19 replicates in the upper airways, more than previous coronaviruses do, that makes it more transmissible.<\/p>\n\n\n\n<p>The significance of the ACE-2 entry point is why researchers are making an improved immune response against the spike protein a vaccine strategy \u2013 see important updated news on vaccines later in this report.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How does it go catastrophically wrong?<\/strong> <strong>Stress on the immune system<\/strong><\/h3>\n\n\n\n<p>In younger people with better immune systems, white blood immune cells called neutrophils and macrophages migrate to the sites of infection and clear infected cells and their debris.<\/p>\n\n\n\n<p>In older people, this immune response is normally slower and less effective \u2013 a condition called <strong>immuno-senescence<\/strong>. The body produces fewer B and T white blood cells. Moreover, B-cells&#8217; ability to produce antibodies declines, as does T-cells&#8217; ability to respond to antigens. This means more and more cells can become infected, which increases the \u2018viral load\u2019 \u2013 and the sheer weight of the virus becomes overwhelming.<\/p>\n\n\n\n<p>Reduced immune response can generate high levels of inflammation and lead to a <strong>cytokine storm<\/strong>, where the body attacks itself. Cytokines, which are signalling molecules, put out a call for an excess of immune cells.<\/p>\n\n\n\n<p>During a cytokine storm these immune cells flood and attack the lungs they should be protecting \u2013 causing what intensive care doctor Chris Meadows calls <em>\u201ca raging fire<\/em> <em>in the lungs\u201d<\/em> and severe breathing difficulty. Hence the focus on oxygen for ICU (intensive care unit) patients.<\/p>\n\n\n\n<p>Blood vessels begin to leak and the blood itself clots, becoming very sticky, potentially leading to a stroke or heart attack. Blood pressure drops dangerously, organs begin to fail, and fever starts. Effectively, the body now considers its own tissues as invaders and has instituted a catastrophically inappropriate response.<\/p>\n\n\n\n<p>The flow of excess immune cells to sites of infection results in more widespread inflammation and compromises not only the lungs and heart, but the kidney, liver and brain. Even mild cases have reported tiredness, and problems with memory and staying focused.<\/p>\n\n\n\n<p>In addition, coronaviruses are known to initiate epigenetic changes (changes in genes), where protective genes are switched off, potentially accelerating the rate that the immune system ages.<\/p>\n\n\n\n<p><strong>All of which makes COVID-19 a very dangerous virus indeed<\/strong> <strong>to high risk groups and <u>much<\/u> more<\/strong> <strong>than a flu-like respiratory disease.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What can help fight the disease?<\/strong><\/h3>\n\n\n\n<p><strong>Steroids<\/strong> can help dampen down the overactive immune system as evidenced by the success of the steroid <em>dexamethasone<\/em> in reducing death rates. But, of course, you need your immune system to be working, albeit at a lower intensity. So it\u2019s clearly far better to protect yourself from infection and\/or block the inflammatory sequence that can lead to a cytokine storm. &nbsp;<\/p>\n\n\n\n<p><strong>Foods and nutrients<\/strong> with a high anti-inflammatory effect can help \u2013 as will those that keep the immune system functioning well. &nbsp;We list these at the end of the report.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What are the symptoms of COVID-19?<\/strong><\/h2>\n\n\n\n<p>The UK NHS currently recognises 3 main symptoms:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Fever or chills<\/li><li>Cough<\/li><li>Loss of taste or smell (new)<\/li><\/ul>\n\n\n\n<p>The American CDC (Centers for Disease Control and Prevention) adds 9 other symptoms:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Shortness of breath or difficulty breathing<\/li><li>Fatigue<\/li><li>Muscle or body aches<\/li><li>Headache<\/li><li>Sore throat<\/li><li>Congestion or runny nose<\/li><li>Nausea or vomiting<\/li><li>Diarrhoea<\/li><\/ul>\n\n\n\n<p>The problem is that many other conditions can cause similar symptoms to these additional nine \u2013 flu, for example. The safest reaction, if you do exhibit any of these other symptoms, is to assume you might have COVID-19 and get tested. (And take the flu jab this autumn.)<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>There is a gradient of severity<\/strong><\/h3>\n\n\n\n<p>A very recent analysis<sup>2 <\/sup>of almost 17,000 patients, (median age 72), has found that symptoms and outcomes can be put into \u2018clusters\u2019 of increasingly severe outcomes. Spotting what cluster a patient is in can help identify how they should be treated \u2013 to try to prevent progression to hospitalisation and improve the chance of recovery and survival.<\/p>\n\n\n\n<p>The average time from identified infection to hospitalisation was 4 days, average duration of stay was 7 days and 17% were admitted to ICU. 60% of hospital admissions were men.<\/p>\n\n\n\n<p>Although the analysis confirmed that 53% had comorbidities, (other underlying health issues), 47% did not. But mortality was much lower in this latter group. The median age of those who died in hospital from COVID-19 in the UK was 80 years, and only 12% of these patients had no documented comorbidity.<\/p>\n\n\n\n<p>The six groups, in order of severity, were:<\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"1\"><li>Having a respiratory problem (cough, sore throat, ear pain, runny nose, chest pain. <strong>Outcome<\/strong>: 16% required a trip to hospital with 1.5% oxygen support.<\/li><li>Respiratory problems but with added fever and lack of appetite. <strong>Outcome<\/strong>: 17.5% needed a hospital visit and 4.5% oxygen support.<\/li><li>Gastrointestinal problems like vomiting and diarrhoea, but not many other symptoms. <strong>Outcome<\/strong>: 24% needed a hospital visit with 3.7% oxygen support.<\/li><li>Severe fatigue, chest pains and cough: <strong>Outcome<\/strong>: 24% needed a hospital visit and 8.6% oxygen support.<\/li><li>Severe fatigue, confusion and skipped meals: <strong>Outcome<\/strong>: 25% needed at least one hospital visit and 10% oxygen support.<\/li><li>Acute respiratory issues, chest pains, fatigue and gastrointestinal problems. <b>Outcome<\/b>: 46% needed at least one hospital visit and 20% needed oxygen support.<\/li><\/ol>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How long does it take for infection to show?<\/strong><\/h3>\n\n\n\n<p>Most people will show symptoms after 4-6 days. But it can be between 1 and 14 days. You can be infectious for 2 days before symptoms manifest and for 10 days after. Average infection duration is 10 days.<\/p>\n\n\n\n<p>Average recovery time is 14 days, but it can take weeks, or in some cases months.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How do we become immune?<\/strong><\/h2>\n\n\n\n<p>When pathogens enter your body, your&nbsp;immune system&nbsp;is activated:-<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Bacteria and viruses, like the one that causes COVID-19, have&nbsp;proteins&nbsp;called&nbsp;<strong>antigens<\/strong>&nbsp;on their surfaces. Each type of virus has its own unique antigen.<\/li><li>White blood cells of your immune system make proteins called&nbsp;<strong>antibodies<\/strong>&nbsp;to fight the antigen. Antibodies attach to antigens like a key fits into a lock, to destroy the invading virus.<\/li><li>Once you&#8217;ve been exposed to a virus, your body makes&nbsp;<strong>memory cells<\/strong>. If you&#8217;re exposed to that same virus again, these cells recognise it and instruct your immune system to make antibodies against it.<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What about a vaccine?<\/strong><\/h3>\n\n\n\n<p>We\u2019re going to need a vaccine because this virus is so highly transmissible. And since so many people are infected but without many \u2013 or even any \u2013 symptoms, how can you trace all the contacts?<\/p>\n\n\n\n<p>Historically, it\u2019s taken years to show that a new vaccine is both safe and effective. The leading science journal <em>Nature <\/em>recently pointed out that 90% of all vaccines that start clinical trials never make it to the end, either because they\u2019re not triggering an effective immune response or a safety concern arises.<\/p>\n\n\n\n<p>The fastest vaccine ever developed was the mumps vaccine and that took four years.<\/p>\n\n\n\n<p>However, the devastation to the health and economies of the world wreaked by COVID-19 means that billions are being poured into compressing the normal timeline. Pharmaceutical companies are using multiple approaches that include conventional inactivated viruses and new, but unproven, technologies like&nbsp;messenger RNA (mRNA) vaccines.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Vaccine frontrunners<\/h3>\n\n\n\n<p>Out of over 170 vaccines under development, here are the frontrunners.<\/p>\n\n\n\n<p><strong>USA\u2019s Moderna<\/strong> has a vaccine using a new technology \u2013 which went from a computer design in January to a human study in just three months. &nbsp;<\/p>\n\n\n\n<p>Messenger RNA (mRNA) uses genetic instructions to build just the coronavirus\u2019s spike protein rather than a weakened version of the virus itself. This then alerts the immune system to build antibodies. Although&nbsp;RNA-based vaccines&nbsp;are easy to develop, none has yet been licensed anywhere in the world or been manufactured and distributed at scale.<\/p>\n\n\n\n<p>Moderna had 45 people on a successful Phase 1 trial that showed strong immune response, but with some mild\/moderate side effects that included fatigue or muscle ache. It is planning a Phase 3 trial to start later in July involving 30,000 participants. Phase 3 trials are designed to confirm and expand the results of the small-scale Phase 1 and 2 trials.<\/p>\n\n\n\n<p><strong>Oxford University&nbsp;and&nbsp;AstraZeneca<\/strong> have what is called an adenoviral vector vaccine. The Oxford vaccine is made from a chimpanzee cold virus that has been genetically altered to produce the coronavirus&#8217;s characteristic &#8216;spike&#8217; protein. This tricks the body into thinking it has been infected and so triggers the immune response.<\/p>\n\n\n\n<p>The Oxford team now has 4,000 people in a UK Phase 3 trial and is enrolling 5,000 people in Brazil, also in a Phase 3 trial. &nbsp;The lack of safety problems in the study so far is a good sign \u2013 as is the fact that it has triggered both antibodies AND a T-cell response, as reported July 21st. This means it is prompting both an innate and an acquired immune system response. There is some indication that immunity with this type of vaccine may require two injections.<\/p>\n\n\n\n<p>An insider has said: \u201cOxford is likely to have the first efficacy data in the world\u201d for a COVID-19 vaccine, possibly as early as August 2020, meaning distribution of the vaccine \u201c<em>could <\/em>begin in the fall\u201d.<\/p>\n\n\n\n<p>Other companies using the adenoviral vector vaccine approach include <strong>Johnson and Johnson<\/strong> and China\u2019s <strong>CanSino Biologics<\/strong>.<\/p>\n\n\n\n<p>Some scientists caution that while adenoviral vectors have been tested in far more people than mRNA vaccines, the technology is used in only one commercial vaccine today: a&nbsp;rabies vaccine&nbsp;used to immunise wild animals.<\/p>\n\n\n\n<p>There is another potential problem. Just as human bodies develop&nbsp;immune responses&nbsp;to most real viral infections, our bodies can develop immunity to the adenoviral vectors themselves. That could make booster shots of adenoviral vector vaccines problematic. On sensing a second injection, our bodies might unleash an antibody attack on the vaccine itself.<\/p>\n\n\n\n<p>Nevertheless, the Oxford concept is probably our best bet for an early vaccine.<\/p>\n\n\n\n<p>Other front running vaccine developers are <b>BioNTech&nbsp;and&nbsp;Pfizer<\/b>, a German\/American collaboration, which has launched clinical trials of four separate vaccines in Europe and the USA with money from the US \u2018Warp Speed\u2019 fund. It reported on July 1st 2020 that initial results showed a good immune response after two shots and claimed that if Phase 3 trials succeed and are approved by regulators, it could start manufacturing \u2018up to 100 million doses\u2019 by the year end 2020.<br>&nbsp;<br><strong>Imperial College London <\/strong>are also using an adenoviral vector vaccine, described as<strong> <\/strong>a \u2018self-amplifying RNA\u2019 vaccine. A Phase 3 trial in 6,000 people is due to start in October. Their advantage is manufacturing scale \u2013 one litre of the Imperial COVID-19 vaccine could be used to vaccinate two million people. To produce that many doses with a conventional vaccine, you could need ten thousand litres.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Earliest dates for a vaccine<\/h3>\n\n\n\n<p>Dr Anthony Fauci is the USA\u2019s top infectious disease expert and has frequently clashed with Donald Trump over coronavirus \u2018facts\u2019.&nbsp;&nbsp; He says he\u2019s <em>\u201ccautiously optimistic\u201d<\/em> scientists will be able to create at least one safe and effective vaccine by the end of the year, or early 2021.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Multiple different vaccines?<\/h3>\n\n\n\n<p>To ensure that a vaccine is safe in&nbsp;<em>all&nbsp;<\/em>recipients \u2013 young, elderly, healthy or&nbsp;those with risk factors for severe reactions to COVID-19 \u2013 each of these sub-populations needs to be represented in clinical trials.<\/p>\n\n\n\n<p>That\u2019s why Dr Peter Hotez from the UN Foundation predicts that there won\u2019t be one vaccine \u2013 but several vaccines with different purposes. One vaccine may mostly target the people at highest risk of getting severely ill or dying. Another might be tailored to people with underlying chronic conditions like diabetes or heart disease.<\/p>\n\n\n\n<p>There could even be a vaccine that provokes a particularly rapid immune response for healthcare workers \u2013 since so many healthcare workers get sick, because they inevitably experience such high \u2018viral loads\u2019.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Effectiveness criteria<\/h3>\n\n\n\n<p>In June 2020, the US FDA issued guidelines for the approval of a COVID-19 vaccine. In common with previous guidelines the threshold for effectiveness is <strong>50%<\/strong> \u2013 patients who receive the vaccine should be at least HALF (50%) as likely to be infected. That may sound less than ideal on a personal level, but on a national scale it would save millions of infections and enable health services to cope with an expected second wave.<\/p>\n\n\n\n<p>A note of caution. Douglas Reed, an aerobiologist at the University of Pittsburgh Center for Vaccine Research warns of a possibility that vaccinated people could still spread the virus. He says: \u201cIdeally, you want a vaccine that would protect against disease and against transmission, so that we can kind of break the chain.\u201d<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How do we measure immunity? Antibody tests<\/strong><\/h3>\n\n\n\n<p>Antibody tests, also called serology tests, measure antibodies to coronavirus in the blood. If you have antibodies, it means you have been exposed to the virus and your immune system has made antibodies against it.<\/p>\n\n\n\n<p>Because COVID-19 is so new, there hasn&#8217;t been much time for scientists to check the accuracy of antibody tests. They might create many false-positive results.<\/p>\n\n\n\n<p>Testing for antibodies too soon after an illness can also cause false results. It takes 5-10 days from when you get infected to develop antibodies against the COVID-19 virus<strong>. <\/strong>But in most virus cases, full antibody production takes about 14 days.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>If you&#8217;ve had COVID-19, are you immune?<\/strong><\/h3>\n\n\n\n<p>We don\u2019t yet know for sure \u2013 or how long the immunity may last.<\/p>\n\n\n\n<p>Most people who have recovered from COVID-19 do make antibodies against the virus. But so far, there is no clear evidence that this will protect them against the virus if they&#8217;re exposed to it again. Here\u2019s what we do know.<\/p>\n\n\n\n<p>Studies show that people are protected against the coronaviruses that cause the common cold for up to a year after an infection \u2013 and antibodies against the&nbsp;SARS&nbsp;coronavirus last for up to 4 years.<\/p>\n\n\n\n<p>However, studies have found that most people who have recovered from COVID-19 without hospitalisation do not produce high levels of the antibodies which block the virus from infecting cells.<\/p>\n\n\n\n<p>Worryingly, researchers at Kings College London found that antibody responses to the coronavirus can peak three weeks after onset of symptoms, but then begin to decline after as little as two months. So we may need several generations of vaccine to get to a truly effective one \u2013 which was what happened with the flu vaccines in the early years.<\/p>\n\n\n\n<p>Whilst these early indications don\u2019t necessarily translate to final vaccine results, it is a caution that a vaccine might not be the immediate \u2018get out of jail\u2019 solution that we all hope for.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Could herd immunity protect us?<\/strong><\/h3>\n\n\n\n<p>Herd immunity happens when a large part of the population \u2013 the herd \u2013 is immune to a virus either because they got vaccinated or had already been infected. This makes it harder for a virus to spread.<\/p>\n\n\n\n<p>The more contagious a virus is, the more people are needed for herd immunity to take effect. The COVID-19 virus is so contagious that it\u2019s estimated about 70% of people in a community will need to be immune to have herd protection. &nbsp;The <em>New Scientist<\/em> published figures on 20<sup>th<\/sup> June estimating that the percentage of people who have been infected in the UK could be between 20% and 27%.<\/p>\n\n\n\n<p>A peer-reviewed study published in the <em>Lancet<\/em> medical journal in early July 2020 claimed that&nbsp;COVID-19 antibodies in Spain\u2019s population&nbsp;were as yet<em> \u201cinsufficient to provide herd immunity.\u201d<\/em><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>The \u2018game changer\u2019 drug? Interferon beta<\/strong><\/h3>\n\n\n\n<p>On July 20th, a new drug called SNG001 from biotech company Synairgen was announced. It doesn\u2019t necessarily stop you getting infected, but it cuts the risk of a severe reaction by a claimed 79%. The trial size was small \u2013 50 people \u2013 and results have still to be published in a peer reviewed journal, but what we do know is that it uses a protein called <strong>interferon beta-1a<\/strong> (IFN-beta), which the body naturally produces when faced with a viral infection.<\/p>\n\n\n\n<p>Meantime, several foods also naturally increase the body&#8217;s own production of interferon beta \u2013 including black and green tea (at the levels of 5 cups a day), and shiitake and maitake mushrooms. Vitamin D seems to enhance the effect of IFN-beta.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Protective measures against infection<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>F<\/strong><b>ace masks and social distancing<\/b><\/h3>\n\n\n\n<p>Countries like the UK and USA, which are taking longer to achieve widespread mask usage, whether by policy or cultural attitude, have suffered more virus cases and fatalities.<\/p>\n\n\n\n<p>The UK is now in line with many other countries to mandate wearing a facemask in shops. Analysts at the <em>Lancet<\/em> conclude this could cut the average risk of infection by up to 15%. The N95-style mask offers the most protection, compared with disposable masks. So, although they are stuffy and uncomfortable, the potential drop in transmission is significant.<\/p>\n\n\n\n<p>The <em>Lancet<\/em> paper (based on 172 international studies) found that eye protection (face shields) offered a 12% reduced risk and that reduction to 1 metre distancing is a reasonable change. The increase in risk by reducing from 2 metres to 1 metre is just 2%.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Airborne transmission including aerosol (smaller) droplets<\/strong><\/h3>\n\n\n\n<p>Until now, the WHO \u2013 and therefore most governments \u2013 have maintained that the virus is spread mainly by contaminated surfaces and by droplets generated by coughing, sneezing and talking. These droplets are relatively big and thought to travel moderately short distances \u2013 no more than 2 metres \u2013 and then drop quickly from the air.<\/p>\n\n\n\n<p>On July 8<sup>th<\/sup> 2020, however, an international group of 237 clinicians, infectious-disease physicians, epidemiologists, engineers and aerosol scientists urged the medical community to acknowledge the potential for airborne transmission by far smaller aerosol (the word derives from &#8216;aero-solution&#8217;) droplets. These can travel further and possibly stay in the air for hours.<\/p>\n\n\n\n<p>It is the potential for \u2018aerosol\u2019 transmission that makes indoor gatherings risky and supports the wearing of masks in shops.<\/p>\n\n\n\n<p>Researchers concerned about airborne aerosol transmission point to the case of a choir rehearsal near Seattle, Washington, on 10th March. Sixty-one members of the chorale gathered for a 2\u00bd hour practice. Despite the availability of hand sanitiser, and choir members refraining from close contact and handshakes, at least half \u2013 33 choristers \u2013 contracted COVID-19 and two eventually died.&nbsp;<\/p>\n\n\n\n<p>A key researcher quoted in the leading journal <em>Nature<\/em> states: \u201c<em>There is a substantial probability that normal speaking causes airborne virus transmission in confined environments<\/em>\u201d. Other researchers have shown that aerosols of COVID-19 remained infectious for at least 16 hours, and were more infectious than aerosols of the SARS or MERS coronaviruses.<\/p>\n\n\n\n<p>As a result, the German Department of Health has stated that any room with several people in it should be well ventilated and is considering recommending against air re-circulation in buildings and\/or filtering through UV light. I understand that the WHO is reconsidering its stance on aerosol transmission.<\/p>\n\n\n\n<p>Public transport and taxis are recognised as bringing elevated risk, as are offices and lifts \u2013 but one barely mentioned route for aerosol transmission is the lavatory.<\/p>\n\n\n\n<p>Here\u2019s how. If someone recovers from COVID-19 they will stop shedding the virus from respiration after about 10 days. But the virus can still be in stools for as much as 17 days \u2013 and the act of flushing can \u2018aerosolise\u2019 faecal particles. So office workers should be warned to close loo lids and toilets should be regularly swabbed with disinfectant.<\/p>\n\n\n\n<p>The virus lingers in faeces because the gastrointestinal tract has millions of cells that express the protein called ACE-2 (angiotensin-converting enzyme 2) which, as we have seen, is the receptor that helps the virus attach to the surface of the host cell.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Hand washing and sanitisation<\/strong><\/h3>\n\n\n\n<p>The average person touches their face, nose or eyes <strong>10 times an hour<\/strong>. And these are the three key entry points for the coronavirus. So using a sanitiser into or out of a shop is not being fussy \u2013 it is a sensible precaution for yourself and others. As is frequent hand washing with soap.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Extra vitamin D?<\/strong><\/h3>\n\n\n\n<p>The UK\u2019s National Institute for Clinical Excellence (NICE) points out that there are no studies on the use of vitamin D for the treatment of COVID-19. Although NICE acknowledges that there is a correlation between lower vitamin D status and the development of COVID-19, they say this might be confused by other factors, like a high BMI and underlying health conditions.<\/p>\n\n\n\n<p>This might be overly cautious. A study published in the journal <em>Aging Clinical and Experimental Research<\/em> looked at coronavirus and vitamin D levels in 20 European countries. It commented:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p><em>\u201cVitamin D has been shown to protect against acute respiratory infections &#8230; and older adults, the group most deficient in vitamin D, are also the ones most seriously affected by COVID-19.\u201d<\/em><\/p><\/blockquote>\n\n\n\n<p>The online journal <em>medRxiv<\/em> further analysed coronavirus data from 10 countries. They found that low vitamin D levels are associated with a dangerously overactive immune response, whereas vitamin D helps keep this danger and inflammation under control.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What can you do to help protect yourself and your family?<\/strong><\/h2>\n\n\n\n<p>It\u2019s very clear from the opening of this report that chronological age is only a crude risk factor for turning the coronavirus from an illness into a killer. The real dangers are the weakening of the immune system and accumulated high levels of inflammation \u2013 which we and others have called \u2018inflamm-ageing\u2019.<\/p>\n\n\n\n<p>So, with the probability of us getting a vaccine around early 2021, but that it may not initially give long-lasting immunity, this is what we suggest in addition to the measures above. The aim is not necessarily to prevent infection but to help cut the risk of a severe outcome:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Increase foods known to support and enhance the immune system and reduce inflammation<\/strong><\/h3>\n\n\n\n<p>These include dark polyphenol-rich red and blue berry fruits, citrus fruits (for vitamin C), green and black tea, garlic, leafy green vegetables (broccoli and kale are especially good), nuts and seeds and avocados (for vitamin E), shellfish (zinc) and mushrooms. &nbsp;<br><br>To these, add foods that support a healthy microbiome\/gut \u2013 which is home to at least 70% of your immune system cells. Feature <strong>fermentable fibre foods<\/strong> \u2013 oats, whole grains, beans and legumes like chickpeas and soybeans \u2013 and <strong>fermented foods<\/strong> like sauerkraut, kefir and real yoghurts that are an important source of probiotics. Plus prebiotic foods that feed your probiotic bacteria, like garlic, onions, leeks, asparagus and flaxseeds.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Maintain activity levels<\/strong><\/h3>\n\n\n\n<p>Ensure you&nbsp;are physically active for half an hour or more on at least 5 days a week \u2013 &nbsp;exercise boosts immune function.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Take a daily health supplement<\/strong><\/h3>\n\n\n\n<p>A daily comprehensive supplement like <a href=\"https:\/\/uni-vite.com\/supplements\/\"><b>NutriShield<\/b> <\/a>is formulated to boost the levels of anti-inflammatory, plant derived nutrients like polyphenols in your diet. It also contains many nutrients that underpin the working of the immune system, including zinc, folic acid, copper and vitamins A, B6, B12, D3, E, and Omega 3.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Consider an immune supplement<\/strong><\/h3>\n\n\n\n<p>An immuno-modulator like <strong><a href=\"https:\/\/uni-vite.com\/supplements\/\">ImmunoShield<\/a><\/strong> can help normalise the immune response. If an immune response is weak, an immuno-modulator strengthens it, but if the response is excessive, it brings it back towards normal. That\u2019s why the evidence is that Wellmune 1-3, 1-6 beta glucans in ImmunoShield will not cause or contribute to a cytokine storm.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Look at a probiotic supplement<\/strong><\/h3>\n\n\n\n<p>Some probiotic strains have been shown to support the natural production of antibodies and may increase the production of T-cells and Natural Killer cells. These strains include Lactobacillus rhamnosus, L. casei and the very robust Bacillus coagulans They are included in the multi-strain probiotic <strong><a href=\"https:\/\/uni-vite.com\/supplements\/\">Microbiotic Plus<\/a><\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Take extra vitamin D3<\/strong><\/h3>\n\n\n\n<p>For most people, 800 IU of vitamin D3 should be enough in the summer. But once we get to October, we recommend supplementing at 2,000 IU a day (see <a href=\"https:\/\/uni-vite.com\/supplements\/\"><strong>Uni-Vite<\/strong> <strong>Vitamin D<\/strong><\/a>). And if you feel you want extra protection, this level is well below the upper safe limit even during the sunnier months (the UK upper safe limit for vitamin D supplementation being 5,000 IU).<\/p>\n\n\n\n<p>I hope this report has been helpful.<\/p>\n\n\n\n<p>Stay safe!<\/p>\n\n\n\n<p>Colin Rose<\/p>\n\n\n\n<p>July 2020<\/p>\n\n\n\n<p><strong>References:<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"1\"><li>Why does COVID-19 disproportionately affect older people: Mueller et al, <em>Aging<\/em> (Albany NY). 2020 May 29;12(10):9959-9981. doi: 10.18632\/aging.103344.
