Does Sars-Cov-2 exist?
I ask this question because a number of people have claimed the entire Covid pandemic was a made-up event. A ‘plandemic’ If you like. There was no new virus, it never existed. Others question whether or not viruses actually exist, as ‘they have never been seen.’ I get these comments quite a lot on my blog. I also see people on X, and elsewhere, making similar claims. Conspiracy theory?
I am also often accused of being a conspiracy theorist. That lazy, lazy, form of attack, which never requires any evidence. Nor any attempt to define what a conspiracy theorist may actually be. It is just a ‘catch all’ insult and dismissal. Which continues to be enormously effective. Strangely.
However, when we get into the ‘viruses don’t exist,’ or ‘Sars-Cov-2 doesn’t exist’ territory, I too find myself tempted to dismiss such comments as a conspiracy theory. I try to resist. Everyone is entitled to their opinion. But …
Here I want to try to explain why it is that I am pretty much one hundred per cent certain that viruses exist and that Sars-Cov-2 was a new strain/variant of coronavirus not seen been before.
Do viruses exist?
Some may think this is a stupid question to ask. ‘Of course they exist …you idiot. Don’t you know anything.’ However, it is always worthwhile taking the time to challenge things you believe to know, to be sure. If not all the time, then at least from time to time. A stress test, if you like.
After all, most people are convinced that a raised cholesterol level causes heart disease, and there appears to be a vast mountain of data to support this hypothesis. Only an idiot, or conspiracy theorist, could think otherwise.
Well, ahem, disclosure of interest …. I have spent forty years studying this area, and I am absolutely certain that cholesterol (or LDL – Low Density Lipoprotein) does not cause heart disease. If the mainstream medical research world can get it wrong about something this fundamental, then perhaps they can be wrong about other seemingly inarguable facts?
One of my somewhat geeky hobbies is studying medical ideas from history, which turned out to be complete bunkum. There are many. They include the knowledge that blood does not circulate round the body, that Miasma causes infectious diseases, and the absolute requirement for strict bed rest following a heart attack. To name the first three that spring to mind.
One thing I learned very early on was that the person who first dared challenge the prevailing dogma would be ruthlessly attacked, their reputation stomped into non- existence. Or, in the case of … ‘could doctors please wash their hands to stop spreading horrible diseases’ Semmelweis … beaten to death in a secure mental hospital.
Luckily, someone would finally come along to change things around. Who then succeeded in garnering all the praise. But how did they succeed when others ended as smoking ruins? I have never really managed to work this out.
I certainly wish I knew. Perhaps it was simply a combination of time and persistence. Maybe those who succeeded had terrific communication skills. Maybe the pile of contradictory facts simply grew too enormous to be ignored?
Alternatively, it could be that those established ‘experts’ who had most to lose grew old and gave up the fight to maintain the status quo – then died. As Max Plank once remarked. ‘Science progresses one funeral at a time.’
Back to viruses – and their existence
Here follows information that I can find no reason to doubt.
The first virus ever to be identified was the tobacco mosaic virus. To be more precise, an ‘agent’ was identified. Something far smaller than a bacterium. It was initially called ‘Contagium vivum fluidum.’ Which sounds like something from Harry Potter. A rough translation could be: ‘a contagious living thing that can move about – and infect, and harm, living things.’
Early researchers could not see it, whatever it was. But they knew it had to exist because of the carnage it left behind on their highly valuable tobacco plants. They had previously worked out how to fix bacteria in a gel, which gained bacteria the name ‘contagium fixum.’ And bacteria could be seen under an optical microscope. At least from the late nineteenth century onwards.
However, this agent could not be fixed, nor seen. So, it had to be something else, very, very small – perhaps not even a solid. Which is why we ended up with the term fluidum.
Beijerinck, in 1898, was the first to coin the term, ‘virus’. Virus is Latin for poison or noxious liquid. Which is not a terribly accurate name for a tiny wee solid thing.
‘Investigating the cause of mosaic disease of tobacco, previously shown to be an invisible and filterable entity, Beijerinck concluded that it was neither particulate like the bacteria implicated in certain infectious diseases, nor soluble like the toxins and enzymes responsible for symptoms in others. He offered a completely new explanation, proposing that the agent was a “living infectious fluid” whose reproduction was intimately linked to that of its host cell.’ 1
That last bit about reproduction was certainly a good guess. As for the living infectious fluid bit … not so much.
However, it was not until the 1930s that anyone started to pay much attention to ‘viruses.’ No-one knew much about them, even if they truly existed. Virology wasn’t a research area until the second half of the twentieth century,
The first time a virus was ever spotted was in 1939. This was almost immediately after the first electron microscope was created, by Siemens, in 1939. You could say that that the moment it became technically possible to see a virus, they were seen. And lo, vaccination was born. Sorry… couldn’t resist.
Thus, when people state that viruses have never been seen, I tend to sigh gently to myself. This is simply not true. You can see hundreds of different types. Thousands, even millions.
A CORONAVIRUS

For the last eighty-five years, we have been seeing them in ever greater detail. You can also grow a virus in the lab. You can define their exact RNA, or DNA, sequence. You can construct a new virus from lab created RNA – if you so wish.
In addition, you can add bits to existing viruses to make them more, or less, infectious to humans. This is known as gain of function research. In many ways there is little that we don’t know about them.
We know what they look like, how they replicate within host cells, what their gene sequence is, how they attach to cells in order to gain entry. Yet, and yet, their ineluctable essence remains difficult to grasp.
In what direction, exactly, will they mutate? Why do they sometimes spring back to life? I am thinking of my cold sores here. Will they jump across from animal hosts to kill us all? And why don’t we have any decent drugs to stop them being so damned deadly? I am thinking more Ebola here.
It is simply because they are so tiny, that is hard to get a handle on them. They float around us, unknown and in important ways unknowable. I remember reading an article where someone tried to work out, at the peak of the Covid pandemic, how large a container you would need to hold all the Sars-Cov-2 viruses in the world.
The answer was, a can of Coke, as reported by the BBC.
‘If you collected up every Sars-CoV-2 virus particle in the world, it would fit inside a soft drinks can.’ 2
Which I find pretty mind-boggling. It also gives you some idea of how small they are. And how little, in terms of volume, is required to infect and potentially kill someone. But what of Sars-Cov-2 itself. Is it real, was it real, was it a new virus that had never been seen before? I believe the answers here to be yes, yes, and yes.
The evidence that supports Sars-Cov-2 as a ‘new’ virus
You can argue about when a new strain of an existing virus becomes a distinct ‘new’ virus. Or even what to call each variant. Naming things has never been a precise science:
‘The issue of naming the coronavirus had arisen about twenty years back and the need for a standard nomenclature system was asserted after the emergence of SARS in 2002–2003 . However, the issue resurfaced in early 2020 when a novel coronavirus (SARS-CoV-2), deadlier than the previous, brought the world to a halt. Over the years, no solid standard naming system has been developed and implemented.’ 3
But, for now, I will say Sars-Cov-2 represents a distinct ‘new’ virus and leave it at that. Clearly coronaviruses themselves are not remotely new. They have been around, and known about, for a long time. They are called a ‘corona-virus’ because of the crown, or halo, of protruding spikes (the spike protein). There are four main subgroups. Alpha, beta, gamma and delta – although this will doubtless change. I think it may have already happened.
They can infect other animals. Cats, for example, die from coronavirus infections. In humans they have been causing the common cold for many years.
Coronaviruses are an RNA virus, which means they only contain a single strand of genetic material. Some viruses have DNA – two strands. DNA viruses mutate relatively slowly. However, RNA viruses tend to mutate rapidly, and veer all over the place. Which means that:
- Vaccines are likely to become ineffective pretty rapidly (see under influenza)
- They can more easily avoid host immune defences, so you can become infected again and again.
Be afraid of the mutations. One form of coronavirus that mutated was MERS-CoV. [Middle-East Respiratory Syndrome – Coronavirus]. It had a reported infection fatality rate of thirty-five per-cent. It came, it is believed, from camels. MERS scared the bejesus out of the virologists. Luckily it did not prove highly infectious between humans. So, it faded away. Although it has not gone.
We also had SARS-Cov-1 (Severe Acute Respiratory Syndrome – Coronavirus, mark 1). Which kicked off in 2002, in China – quelle surprise. It spread to nearly thirty countries but caused only nine hundred reported fatalities. Why did it not kill more, and spread more widely? The widely believed answer is that it was only infectious – could only be passed on – when people had symptoms. So, if you isolated people who had symptoms, no-one else got infected. End of viral spread.
Then we had Sars-Cov-2, or Covid19, or just Covid. Call it what you like. It was new. Why do I believe this?
One of the main reasons is because I had very direct experience of the effects it had. I was working on the front line during Covid, helping to manage the elderly in rehabilitation units and nursing homes. I went in, every single working day. I saw over thirty people die of this ‘new’ virus. Possibly more. I kind of lost count.
Their deaths were often strange. I have seen a lot of people die over my decades working as a doctor. Some sudden, mostly slow. But with Covid people died ‘differently’. The most unusual thing was when their oxygen saturation levels – the amount of oxygen contained in red blood cells – started to fall, dramatically. Despite this, they often had no symptoms.
Maximum oxygen saturation is 100%. People with a level of 80% are in trouble and need to get into hospital a.s.a.p. They will be struggling badly and usually need oxygen. With Covid, I was sticking on a probe and getting levels of 70%. Which would normally mean – almost dead, or just about to die. Instead, there was nothing to see. Breathing rate normal, fully conscious and alert. Smiling and chatting even.
Then, less than ten minutes later, in two cases. Dead. Bang, gone. What the …?
This observation, of very low saturation levels in otherwise well people, was described all over the place. According to what I had been taught, it should not have been possible. But clearly it was, because it happened.
Here from the University of Boston. ‘Three Reasons Why COVID-19 Can Cause Silent Hypoxia.’
“We didn’t know [how this] was physiologically possible,” says Bela Suki, a BU College of Engineering professor of biomedical engineering and of materials science and engineering and one of the authors of the study. Some coronavirus patients have experienced what some experts have described as levels of blood oxygen that are “incompatible with life.” 4
Then there was the sudden loss of smell. Our next-door neighbours have five boys. One of whom was working in Macao at the start of it all. He came back in March 2020. The boys all then reported sudden loss of smell. One of them farted and the others could smell nothing. They were otherwise well.
Pretty much the same thing happened with my son. It started when my wife cooked him some scrambled eggs and they tasted of almost nothing. About which he complained bitterly. Then, everything tasted of nothing. Apart from things the tongue can sense. Salt, sweet, bitter, sour and umami. Then my daughter, who did have symptoms of Covid, lost her sense of smell completely. She was working as a junior doctor on a Covid ward in Wales.
This occurred very early on, before anyone had even mentioned loss of smell, or very low oxygen saturation accompanied by a complete lack of symptoms. This was not a case of me seeing things I had been told I would see. These were signs and symptoms that I had neither come across, nor read about.
I knew very early on that a loss of taste/smell was diagnostic of Covid. It was ‘pathognomonic’, to use the medical term. Although it took about nine months for this symptom to be accepted by the mainstream. Having said this, it never happened to me, despite the fact that I was surrounded by Covid every working day, for months. And I lit up Lateral Flow Tests from time to time.
Anyway. To see one set of symptoms you have never seen before could be considered coincidence. To see two. that’s new. Then there were the blood clots, and the cytokine storms. Yes, the latter two can be seen with other viral infections. But not to the same extent. To my mind, these were also new, at least in their intensity.
You would have to work pretty damned hard to convince me that Covid was not a new disease, caused by a new virus Sars-Cov2. Things that you have never seen before, seen with your own eyes, tend to be the most convincing.
More science
More scientific support for the fact that Sars-Cov2 comes from the way it caused damage, and the specific type of cells that it damaged. Which fits with the known structure of the virus itself.
One fascinating thing about viruses is how they manage to gain entry to a cell. In almost all cases they attach to a protein, or proteins, on the cell membrane. This allows them to be absorbed/invaginated into the cell. This represents a ‘lock and key’ mechanism.
HIV, for example, locks onto a receptor called the ‘C-C chemokine receptor type 5 (CCR5’). Then, and only then, is it granted entry from the outside world into the cytoplasm – the inside world of a cell.
There are some people, not many, who have a mutation of the CCR5 protein called the Delta-32 mutation which prevents CCR5 from being expressed on the outside of the cell membrane. So, HIV cannot attach, therefore you cannot get AIDS.5
The Ebola virus also attaches to CCR5 protein. If you have the Delta-32 mutation, you can’t get HIV or Ebola. Or to be slightly less black and white, you are almost entirely resistant to them. There is now much work being done in the area.
‘The triad “CCR5, extracellular vesicles and infections” is an emerging topic.’ 5
It is why viruses that affect animals e.g. bird flu, usually cannot infect us. We have different proteins on our cells. There is no lock, and therefore entry is barred. However, if the virus mutates just a little bit, then you can end up with a key that fits a human lock and then … watch out. Species jump is what keeps virologists awake at night. Ebola is a species jumper. Luckily, it does not spread very easily.
When it comes to Sars-Cov-2, the virus gains entry to human cells by attaching to a protein known as the ACE2 receptor. A common protein/receptor found on many cells. Once the virus latches on, this triggers downstream processes that ‘open up’ the cell to viral entry. The specific ‘key’ in this case is the S1 protein that sits on the spike protein.
As a quick jump sideways, the lock and key system is precisely how LDL molecules gain entry into cells. They attach to a protein receptor ‘lock’ known as the LDL receptor. The key here is the ApoB-100 protein ‘key’, which is attached to all LDL molecules. After locking onto the protein receptor, the LDL molecule is accepted into the cell. LDL molecules and viruses are just about the same size. [Getting into a cell would be impossible for either of them, without a magic key].
Anyway, back on track. Certain cells in the body have far more ACE2 receptors than others. They are most abundant in ‘epithelial’ cells lining the lungs, blood vessels and the small intestine.
‘ACE2 was shown to be abundantly present in human epithelial cells of the lung and enterocytes of the small intestine as well as in endothelial cells of the arterial and venous vessels.’6
Knowing the type of cell that Sars-Cov2 is designed to lock onto you would expect to see the following triad. Lung damage, diarrhoea (caused by damage to cells lining the intestine) and vascular damage – creating blood clots, causing heart attacks and strokes and suchlike. Which is exactly what we did see.
Once you knew that the new spike protein fitted perfectly onto ACE2 receptors, it became possible to predict what would happen. Including, almost certainly, the loss of sense of smell, caused by damage to the ‘epithelial’ lining of the nose.
At this point I am not sure what else I can say. I think the evidence is overwhelming that viruses exist. Equally I find it virtually inarguable that Sars-Cov2 is/was a new coronavirus not seen before. We can see it, we can grow it, we can test for it, and it causes damage predicted by the type of cells it gains entry to – and therefore kills.
Was it made in a biolab in Wuhan, or did it start off in a wet market in Wuhan – having evolved from a bat virus – then travelling a thousand miles across China … without any sign of it on the way? Dum de dum, taps fingers on desk.
I shall let you decide on that one. Bear in mind that the biolab leak explanation would place greater blame on China, and the Chinese authorities are the only ones who have the evidence to support, or fully refute, this theory … So, I wouldn’t hold my breath on that on. But in many ways, it doesn’t’ really matter where it came from. It was a virus, it was new, it arrived. It did its thing.
Although, having just said that, the main purpose of an enquiry should be to try and learn how to stop bad things happening again. If the virus was made in a lab, and then escaped, we need to ensure that man-made viruses like this never escape again. Or are never made again?
Alternatively, if the virus evolved on a long and winding road across China, on its way to a wet market, well, we probably need to ask China, and other countries with wet markets to close them down. Or do something else. Not quite sure what the something else would be. Autoclave all bats? Death to all pangolins?
Summary
I never like to say that something is true, or false, or a fact, as this makes it very difficult to examine that thing again with an open mind. I prefer to define ideas as probable, possible and unlikely. However, I will say that it is just about 100% certain that:
- Viruses exist.
- Sars-Cov2 was/is a ‘new’ version of a coronavirus.
Next, the reasons why I believe that many people were convinced that Covid was a plandemic. And remain convinced of it, to this day.
