Sweden: Covid 19 deaths no longer stick out.

October 12, 2020

 As schools and colleges have opened and partying has resumed, the number of infections have been rising.

However the deaths attributed to Covid-19 no longer stick out of the average of deaths/day (all causes).

100 years after the Spanish flu, virology still has far to go

October 4, 2020

Medical science does wonders. From amazing surgical procedures to an incredible variety of drugs and a fantastic array of tools and equipment, medicine, as it is practiced today, is light years ahead of where it was in 1918 at the time of the Spanish flu. Yet, medical science has not been capable of quickly defeating the current Wuhan virus pandemic. Health care has improved beyond recognition. Compared to 100 years ago, health services can deploy a bewildering variety of drugs and equipment and therapies to treat the infected.

The effects of the current pandemic are most often compared with the effects of the Spanish flu in 1918. The flu virus was identified in 1933 and the first flu vaccine came out in 1942. However, even today the flu vaccine is thought to be effective only in a little over 50% of cases. It is estimated that the Spanish flu, over a period of 3 years killed between 25 and 39 million people and that about 500 million were infected when the global population was only about 1,800 million. Today with a global population of 7, 200 million it is estimated that at least 35 million have been infected and, so far, over 1 million are thought to have died. The pandemic has lasted 6 months and is still ongoing. The virus was identified very quickly – perhaps one month – but only after the data repressed by the Chinese government and the WHO – leaked out.

The hunt for a vaccine is only 6 months old. There are at least 300 groups actively searching for one. Around 30 proposed vaccines have entered some kind of clinical trials. Estimates of when a vaccine could be readily available range from 6 months to 2 years to never. Money is being thrown at vaccine development at unprecedented levels. Certainly some of the groups chasing a vaccine have zero chance of success but cannot resist the temptation of huge amounts of easy money.

But virology is far from a settled science. In fact, there is still debate on whether a virus is living or not. That there are 300 different groups seeking a vaccine is, itself, evidence of 300 different opinions. During the past 6 months a bewildering variety of suggestions have been made for prophylactics, remedies and cures. Every single one has come from a “medical specialist”. The best advice is still “avoid infection” (by social distancing and masks which may or may not work), and hope. There are no preventive drugs and there are no cures (beyond treating symptoms). If and when vaccines are found, they will vary in how effective they are. Estimates of how expensive a vaccine may be range from 30$ to 300$ per dose for either a one-dose or a two-dose vaccine, with immunity available for periods ranging from 3 months to 1 year after vaccination.

Everyday new “experts” are trotted out on TV. But the science is not settled and there are no experts. The simple reality is that compared to 100 years ago, this pandemic has medical science just as stymied as the Spanish flu did – but at a very much higher level of knowledge.

Wuhan virus perspective

It takes time to gain perspective.

Wuhan virus versus the Spanish Flu.


The Wuhan virus and common sense

July 26, 2020

Common sense went on vacation sometime in March 2020.

It seems to be an extended vacation and it is not certain when it will return.

Virus sense

Lockdowns seem to be counterproductive. They solve nothing. Instead they extend the life of the virus and prolong the pandemic. They could have maximized the global death toll. The only positive is that they may reduce the load on the hospitals.

The two areas where Sweden got it wrong were:

  • they did not restrict infection sources from reaching the care homes, and
  • they locked up the elderly in their “infected prisons”

But all the rest they did right.


Epidemiology is still more art than science and sometimes just speculation

July 24, 2020

The Wuhan virus, after 6 months, is still not under control.

I have grown a little tired of being told by all kinds of people that they are just following the science in the fight against the Wuhan virus. What science? There is a widespread delusion that epidemiology is a “settled science”. Epidemiology is, in reality, a mix of science and art and of “social science” (which is always a politicized view of behaviour). It is about “the frequency and pattern of health events in a population”. With a little known virus, as in this case, epidemiology relies on models and speculation. When the speculation is garbage, the model results are also, necessarily, garbage. The model results have ranged from the ridiculously complacent to the grotesquely alarmist, but what they all have in common is that they are/were wrong. Nothing surprising in that. That is the nature of modelling. A mathematical model is nothing more than a crystal ball and model results are always forecasts of the future. The problem lies in the delusion that epidemiology is an exact science and that model results give a sound and certain basis for public policy.

In the absence of a vaccine we are being led (or misled) by politicians blindly following the epidemiologists’ speculations about both the characteristics of the unknown virus and about social behaviour. In the space of 4 months the “best” epidemiologists at the WHO have changed their view of the Wuhan virus from being “non communicable between humans”, to “communicable by liquid droplets between humans”, to now be of “air borne transmission”. The experts have been divided whether transmission is from the symptomatic or from the asymptomatic. There are as many speculative views about when herd immunity can be achieved as there are epidemiologists. No one really knows. Art not science. Herds are always moving and herd immunity depends upon leaving the weak behind. Public policy is floundering as it staggers from lockdowns to no lockdowns to social distancing, from masks to no masks to some masks to masks for some, and from testing those with symptoms to restricted testing to mass testing. There is no certainty about whether testing is to be for the virus or for antibodies to the virus.

The Center for Disease Control has this definition of epidemiology:

Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems.

But then they go on:

…. the practice of epidemiology is both a science and an art.

The reliance on speculation and the resulting weaknesses of epidemiology are well known and there are many scientific articles about spurious but statistically significant epidemiological forecasts. This article in the BMJ from 2004 is just an example.

The scandal of poor epidemiological research

Something surely must be wrong with epidemiology when the new editors of a leading journal in the field entitle their inaugural offering, “Epidemiology—is it time to call it a day?” Observational epidemiology has not had a good press in recent years. Conflicting results from epidemiological studies of the risks of daily life, such as coffee, hair dye, or hormones, are frequently and eagerly reported in the popular press, providing a constant source of anxiety for the public.  In many cases deeply held beliefs, given credibility by numerous observational studies over long periods of time, are challenged only when contradicted by randomised trials. In the most recent example, a Cochrane review of randomised trials shows that antioxidant vitamins do not prevent gastrointestinal cancer and may even increase all cause mortality. 
Now Pocock et al describe the quality and the litany of problems of 73 epidemiological studies published in January 2001 in general medical and specialist journals. …… Worryingly, Pocock et al find that the rationale behind the choice of confounders is usually unclear, and that the extent of adjustment varies greatly. They also confirm that observational studies often consider several exposures, outcomes, and subgroups. This results in multiple statistical tests of hypotheses and a high probability of finding associations that are statistically significant but spurious. 

Modern epidemiology starting from – say – the 1854 London cholera outbreak has vastly improved public health. But it is not just a science and it is certainly not a “settled science”. The Wuhan virus is not under control. The various public policy interventions (lockdowns of various kinds and the deselection of the old for treatment) have prolonged, rather than shortened, the outbreak. The lockdowns may have protected health systems while maximizing the number of deaths. In fact, politicians have often abdicated responsibility for public policy to epidemiologists and bureaucrats who have not been best-suited to make political decisions. In other cases public policy has exploited epidemiology to protect the system rather than protecting people.

This is not so much to criticize epidemiology as to criticize the manner in which public policy has misused epidemiology. Epidemiology can only be an input for determining public policy. It cannot replace common sense. And it is not a convenient shelter for politicians to hide behind.


Has “flattening the curve” maximized the number of Wuhan virus deaths?

July 22, 2020

I am beginning to think that the international lockdowns may have been a colossal mistake.

The primary objective of “flattening the curve” was to protect health services, not to minimize deaths.

In theory, flattening the curve should have given the same number of deaths but over a longer period of time. In practice, the flattened curve has kept the pandemic alive for much longer than necessary. The lockdowns have ensured that no general immunity has been achieved anywhere. The total number of deaths could well have been lower with a more intense but short-lived pandemic.


“Flattening the curve” Theory

“Flattening the curve” Actual?

The assumption that the curve can be flattened without affecting the area under the curve is speculative and unjustified. The two curves cannot be equated. The reality is that extending the tail of the curve by attempting to flatten the peak may have done more damage than good.

Have the lockdowns actually saved any lives?

Or have they extended the pandemic such that more lives have been lost than if there had been no lockdowns. And at the cost of a global economic shutdown. Fewer lives lost per day but for a very, very long time as opposed to many lives lost per day over a much shorter period of time.

Flattening the curve may well have maximized the number of deaths.

The Chief Minister of Karnataka State in India actually made some sense yesterday when he said:

“There will be no lockdown in Bengaluru from tomorrow. However, I humbly request the people of Karnataka — with folded hands — to wear masks and to practice social distancing. This is the only way to combat COVID-19, at least till a vaccine is found,  …….. People can resume work and businesses as usual, outside containment zones. A stable economy is essential for the state to combat the coronavirus pandemic effectively.” 

Indeed. Protecting a health service in a collapsed economy is not possible.


So what exactly have the lockdowns achieved?

July 20, 2020

The Wuhan virus continues to lay waste.

Cases are on the rise again.

Deaths are also rising globally.

The pandemic is now expected to continue into 2021.

There will be no reliable vaccine at least until spring 2021.

So, what exactly have the lockdowns and economic disruption achieved?

If anything?

But one thing is certain. The lockdowns have extended the life of the pandemic.

Without any lockdowns there may well have been a sharper peak.

But it could possibly all have been over by now.

The WHO is clueless. It went from “no person-to-person transmission” to “transmission by fluids only” and is now on to “air-borne transmission”.

Alarmist models don’t make for settled science.




Covid puts ethics under pressure in Sweden

July 18, 2020

The Wuhan virus pandemic is bringing many ethical questions about the treatment of the aged into stark relief.

90% of all deaths in Sweden due to the Wuhan virus have been of those over 70 years. I have been less than impressed by the Government and the National Board of Health and Welfare (Socialstyrelsen) in Sweden. Their “remaining useful life” criterion is rational but hypocritical in trying to maintain the pretense of it not being age discrimination. They have effectively removed those over 70 from their definition of the herd to be protected. Even the trade unions were extremely concerned about protective equipment for their members working in the care sector. They threatened to strike at some care homes. I suppose that very few inmates of the care homes are active trade union members.

Suspected cases in care homes were usually kept away from the health care system and its facilities. The health system was under stress but never overwhelmed. Isolating those over 70 certainly helped reduce the pressure on the health services, but did not protect the over 70s from themselves being infected in their care “prisons”. In most cases the inmates were infected by their carers. However, unlike the inmates, the carers had recourse to the hospitals. The isolation also eliminated – probably as intended –  any chance of the +70s participating in any herd immunity that may develop. In the fight against the Wuhan virus, “Official Sweden” (from government to bureaucrats), has taken the position that the over 70s are not part of the herd and are expendable.

Take this ethical question:

When an 80+ year old in a care home contracts a treatable condition (bacterial pneumonia for example), but is misdiagnosed (assumed) to have the Wuhan virus and, without any further testing, is put on “palliative” care (morphine) leading inevitably to death, is it 

    1. unfortunate accident? or
    2. humane care?, or
    3. negligence?, or
    4. incompetence?, or
    5. euthanasia?, or
    6. justifiable manslaughter?, or
    7. murder?

“Official Sweden” has generally taken the comfortable position that such cases  – and there are more than a few – are all “unfortunate accidents”. I would put it less complacently at 3 on the list above or even higher.

The nice thing about “unfortunate accidents” is that nobody is accountable and nobody needs to take any responsibility.


All the Chinese viruses from the Spanish flu to the Wuhan coronavirus

July 10, 2020

This is the Wuhan virus and it did come from China. 

Trying to be politically correct is more misleading and probably the cause of more disinformation and self-delusion than any other. Political correctness applied to the scientific process is particularly destructive and gives us the burgeoning levels of fake science. Results are determined before the investigations have begun. For the WHO it is servility to Chinese interests which has prevented the Wuhan coronavirus from being named the Wuhan virus.

It now seems highly probable that even the Spanish flu of 1918 originated from China.

National Geographic:

 The deadly “Spanish flu” claimed more lives than World War I, which ended the same year the pandemic struck. Now, new research is placing the flu’s emergence in a forgotten episode of World War I: the shipment of Chinese laborers across Canada in sealed train cars.

Historian Mark Humphries of Canada’s Memorial University of Newfoundland says that newly unearthed records confirm that one of the side stories of the war—the mobilization of 96,000 Chinese laborers to work behind the British and French lines on World War I’s Western Front—may have been the source of the pandemic. …..

…. The 1918 flu pandemic struck in three waves across the globe, starting in the spring of that year, and is tied to a strain of H1N1 influenza ancestral to ones still virulent today.

There is little doubt that the current pandemic originated from Wuhan though, every so often, some journalist or “scientist” who is part of the China lobby will cast doubt on that. 


The Asian Flu in 1956 killed between one and four million people worldwide. SARS in 2002 infected 8,098 and killed 774 in seventeen counties. H7N9 emerged ten years later to strike at least 1,223 people and kill four out of every ten of them. Now, the milder, yet more infectious COVID-19 has sickened more than 70,000 across the globe, resulting in 1,771 deaths.
All of these outbreaks originated in China, but why? Why is China such a hotspot for novel diseases?

“It’s not a big mystery why this is happening… lots of concentrated population, with intimate contact with lots of species of animals that are potential reservoirs, and they don’t have great hygiene required. It’s a recipe for spitting out these kinds of viruses,” Dr. Steven Novella recently opined on an episode of the Skeptics’ Guide to the Universe.

South Central China is a noted “mixing vessel” for viruses, Dr. Peter Daszak, President of EcoHealth Alliance, told PBS in 2016. There’s lots of livestock farming, particularly poultry and pigs, with limited sanitation and lax oversight. Farmers often bring their livestock to “wet markets” where they can come into contact with all sorts of exotic animals. The various birds, mammals, and reptiles host viruses that can jump species and rapidly mutate, even potentially infecting humans. Experts are pretty sure this is precisely what happened with the current COVID-19 coronavirus, which is why, on January 30th, China issued a temporary ban on the trade of wild animals. ………

….. China is also notorious for its misinformation, secrecy, and censorship, which raises the chances that new diseases will fester and spread. Back in early January, Chinese government officials told the public that the new infection’s spread had been effectively halted. This was not true. At the same time, the authoritarian regime bullied health experts who attempted to sound alarm. The young doctor Li Wenliang attempted to warn others about the new coronavirus. He was ‘rewarded’ with a threatening reprimand by police. Li subsequently caught COVID-19 and succumbed to the disease the first week of February.

It may be called the Covid-19 virus but it is the Wuhan coronavirus pandemic
