The Pandemic

The Unnecessary Devastation of the Lockdown

Are COVID-19 Lockdowns Beneficial? A Scaremongering-Free Approach

As of May 22, Australia had suffered 7088 cases of COVID-19 and 102 people had died with the virus*. Most of the fatalities were men aged between seventy and eighty-nine. A sizeable proportion of those admitted to ICU in hospitals were suffering from comorbidity issues such as cardiac disease and diabetes. Australia’s Chief Medical Officer (CMO) has told a Senate inquiry that the Australian government’s actions to lock down the economy saved 14,000 lives.

In the meantime, Camilla Stoltenberg, director of Norway’s public health agency, has confessed:

Our assessment now, and I find that there is a broad consensus in relation to the reopening, was that one could probably achieve the same effect—and avoid part of the unfortunate repercussions—by not closing. But, instead, staying open with precautions to stop the spread.

The cost to the Australian economy of the global pandemic could be as high as one thousand billion dollars, with an additional direct cost to the taxpayer of $260 billion in this year alone. It will be a while before our Prime Minister and the state premiers admit that the continuing lockdown was entirely unnecessary and unjustified.

 

Rampant alarmism

With the support of 289 or more top economists, on April 19 four economists, Edmond, Hamilton, Holden and Preston, denied “that there is a trade-off between the public health and economic aspects of the crisis”. I answered this in an article in the Australian on May 13. Holden and Preston (May 16, 2020) estimate that without lockdowns and similar interventions but presumably with voluntary social distancing, out of our population of 25.5 million 225,000 would have died, based on an assumed fatality rate of 1 per cent and yielding an incredible rate of 882 deaths per 100,000 residents.

The claimed deaths saved are higher than argued by Australia’s CMO by a factor of sixteen times. The same methodology yields nearly three million deaths in the US and seventy million globally. But is this astute economic analysis, or simply fanciful alarmism and fearmongering designed to frighten Australians into acceptance of continuing lockdown?

If one were to accept the Holden–Preston analysis, with an assumed valuation of A$4.9 million per whole of life, the cost of not locking down is placed at A$1.1 trillion. As Paul Frijters (May 18, 2020) has pointed out, deaths are largely confined to the elderly and infirm with very low life expectancy, reducing this outlandish estimate by 95 per cent to a slightly more plausible A$55 billion; and applying the same methodology to the CMO’s more conservative estimate yields a more modest figure of $3.4 billion in comparison with the Commonwealth’s outlay in excess of $260 billion. This is an expenditure of $76 for every dollar saved!

These Holden–Preston death-rate estimates are extreme even relative to discredited forecasts made by Neil Ferguson of Imperial College, London, in March 16, of 510,000 UK deaths and 2.2 million US deaths. These forecasts, with little if any scientific justification, prompted massive lockdowns in the UK and the US, and in much of the rest of the world including Australia.

So far, the UK has experienced 34,600 deaths (54 per 100,000) associated with the virus and the US approaching 100,000 (30 per 100,000), and the global total is 340,876 as of May 22, a very modest rate of 3.7 deaths per 100,000 so far. This is less than 0.5 per cent of the deaths projected by Holden–Preston. Why are these death rates so much higher than Australia’s? Unlike Australia, the UK, with tens of millions of new arrivals in the last few months, is only now commencing mild quarantining arrangements and similarly, quarantining arrangements and bans on non-resident entry to the US did not take place.

By contrast, the far worse “Spanish flu” pandemic of 1918-19 that killed 50 million people worldwide resulted in 12,000 deaths in Australia with only quarantining and social distancing and no lockdowns. This represented a death rate of 236 per 100,000 people or 0.59 per cent of the 40 per cent of the population who caught the flu.

This death rate from by far the worst pandemic to hit the globe in over 100 years is benign compared to the Holden–Preston figure of 882 COVID-19 deaths per 100,000, a factor of 3.7 times higher. The Spanish flu was indiscriminate, killing the young and healthy as well as the vulnerable, while COVID-19 is largely confined to the elderly and those with severe comorbidity factors.

 

International quarantining seems to be effective in the short term

What this analysis does not recognise is that, like Taiwan, Australia is an island nation. While both nations have similar populations, Taiwan is much closer to the Wuhan epicentre of the virus origin. Taiwan began testing arrivals from Wuhan for flu symptoms from December 31, 2019, but Australia did not restrict access from China until February 1, with a ban on all non-resident entry on March 20.

Today Taiwan has had 441 cases and seven deaths. Hence their infection rate has been 6 per cent of ours and their death rate 7 per cent. Moreover, their far superior result to ours, at least from a short-term perspective, was achieved simply by strict quarantining, banning of cruise ships, testing and tracing of carriers, with voluntary social distancing and hand-washing. As a result, their economy is suffering less than many others, with their exports expanding.

The Australian death rate is 0.4 per 100,000 residents, compared with 51 for the UK, France 43, and the USA 29. While it is likely that the 100-fold higher rate in Europe could be partly due to higher population density and adverse climatic factors including winter, a more plausible explanation is the ability of Australia to impose quarantining earlier and more effectively than in Europe.

The ineffectiveness of lockdown

Despite the slowness with which Australia closed its borders and mindful of the Ruby Princess debacle, infections in Australia peaked before the introduction of severe lockdowns and domestic border closures that were always completely unnecessary. Interstate border closures were never supported by the Australian government on medical or other grounds and seem to contravene Section 92 of the Constitution. In the United States, the most common comprehensive social distancing policy adopted is a shelter-in-place order (SIPO) which requires residents to remain in their homes for all but essential activities.

Dave, Friedson, Matsuzawa and Sabia (2020) analyse the difference in the infection rate and death rate between the forty-two states which imposed SIPO laws and the eight Republican states which did not. The study finds that lockdown was effective in reducing the number of detected COVID-19 cases by 44 per cent, but was not able to estimate a statistically significant lower death toll other than noting that it appeared to be lower.

The study is unable to explain the much better record of some states such as Florida that did not lock down than states such as New York that did. To date, New York City with lockdown in place has suffered 16,565 confirmed COVID-19 deaths and an additional 4749 probable deaths which is a rate of 113 per 100,000, far above even the rate experienced by Belgium, the country which is worst in the world. This contrasts with Florida which has suffered 2233 deaths, a rate of 11 deaths per 100,000; while worse than Australia’s performance it is good in comparison with many US states that did lock down.

The differences are in part due to philosophy. New York Governor Cuomo declared a universal policy: “We need everyone to be safe, or no one can be safe,” in locking down all “non-essential” activity, despite not closing either the airports or mass transit. COVID-19 sufferers in New York were forced to return to aged-care homes to free up beds in hospitals. As a result, many thousands of the elderly died in these infected homes.

By contrast, Florida Governor DeSantis prohibited visitors to nursing and aged-care homes and urged the most vulnerable to stay home. Florida is both more humid and less congested than New York City, perhaps accounting for some of the vastly lower death rate. But the large number of Florida retirees makes Florida even more vulnerable than New York City.

The very nature of lockdowns seems to be designed to promote more deaths in certain areas. People confined in cramped and poorly ventilated spaces indoors with insufficient exercise and limited access to sunlight are naturally going to become more vulnerable to flu-like viruses. This was made worse in Australia as nearly all hospital beds were emptied for COVID-19 sufferers who never showed up. Over 7000 respirators have been provided but fewer than twenty have been used. Was this the precautionary principle in action or simply panic?

Contrast confinement on a cruise ship and being free to enjoy healthy beach and ocean exercise in warm sunlight. Police helicopters and boats, eight-foot fencing along much of the coastline and shores lined with police officers, were used in a hugely expensive and futile attempt to drive swimmers and surfers out of the water in many parts of Australia.

Perhaps in a sustained effort to protect dolphins from the threat of COVID-19, socially-distancing surfers were driven from the water at McKenzie’s Bay near Bondi on numerous occasions presumably by police concerned with animal rights. But the surfers with little regard for dolphins were back in the water within minutes.

Another study by Brzezinski, Deiana, Kecht and Van Dijcke (2020) using a panel dataset based on 40 million smartphone devices across the United States, combined with detailed data on state- and county-level government policies, finds that compulsory lockdown increased the time spent at home by up to 39 per cnet but voluntary social distancing also increased the time spent at home. They find that higher socio-economic groups were more likely to respond to physical separation advice, and they recommend voluntary distancing as far more cost-effective than lockdown. However, they do consider stronger measures in areas where voluntary response is problematic.

Hence the evidence from Taiwan, Norway and the US does not indicate that lockdown is either necessary or is more effective than voluntary social distancing in combination with protecting the vulnerable, in reducing COVID-19 morbidity. Two other South-East Asian countries, South Korea and Japan, urged voluntary social distancing and introduced strict tracing and testing but did not enforce lockdown. South Korea has suffered 263 deaths so far, a rate of 0.51 per 100,000, comparable to Australia but perhaps with a lower economic cost, and Japan has suffered 749 deaths, a rate of 0.6 per 100,000, also comparable to Australia’s with lower social cost.

Edmond, Holden and Preston (2020) cite the absence of mandatory lockdown in Sweden as an indication of what might have happened in Australia if we had followed the same path. On the face of it, the Swedish experience does not look spectacularly successful in the short term with 3925 deaths to date or a rate of 39 per 100,000 residents. While this is far lower than many other European countries that did lock down, such as the UK and France, and less than half that of Belgium with a rate of 81 per 100,000, it is far higher than Australia’s and even its neighbour, Denmark, that did lock down and also instigated severe quarantine restrictions.

What accounts for the apparently poorer performance of Sweden relative to its near neighbour in the very short term? Most likely, it has little to do with the difference in lockdown policies but could be accounted for by the fact that, unlike its neighbour, it kept its borders open while at the same time, like Australia, it provides generous public subsidies to displaced workers and firms. Hence it is not surprising that its economic costs are not obviously that much lower than Australia’s and the initial death rate at least, higher due to the absence of quarantining.

Hence the evidence indicates that Australia’s initially excellent COVID-19 record so far is due to relatively early closing of international borders and voluntary social distancing. Compulsory lockdown came late in the piece and has made very little difference other than greatly increasing economic costs and adding to the feeling of social isolation, increased threat of family violence, and the appearance at least of home detention.

It is true that people could venture out for exercise so long as they stayed confined to their local area and did not sit down in the park or anywhere else, while denied access to beaches, oceans, pools, gyms, holiday homes, hotels, pubs, restaurants, community sport and all forms of live entertainment and travel. How easily are people convinced that the government has the right to remove most of their freedoms on no more than a whim!

 

Restrictive measures not justified on medical grounds seem to be there to frighten us

Most of the unpopular measures such as school closure, closure of beaches and water access, bans on sitting on park benches while still social distancing, bans on golf and fishing, and bans on entry to a number of states, were instigated by some state premiers contrary to medical advice provided to the Commonwealth government. Queensland’s CMO, Dr Jeanette Young, stated: “while evidence showed schools were not a high-risk environment for the spread of the virus, closing them down would help people understand the gravity of the situation” (Lynch, 2020).  In other words, people needed to be frightened “for their own good”, a task which Holden–Preston have taken up with alacrity.

Can one argue that this peculiar medical advice to close safe schools was an improvement on the frightening medicine provided to patients in Florence during the plague of 1629 consisting of “oil of crushed scorpions in Greek wine” (Henderson, 2019)? No. Closing schools has contributed to the massive economic burden on the state economy and Australia’s rapid decline in educational standards.

 

Incremental cost of lockdowns over voluntary distancing

Estimating the cost in Australia of compulsory lockdown, state border closures and bans on travel is difficult, as voluntary social distancing would have reduced domestic travel and use of venues such as dining in restaurants, clubs and cinemas in any case. International travel restrictions would have reduced revenues for the university sector from foreign students and the international tourism industry would still have suffered.

Much of this extreme voluntary social distancing was doubtless excessive and not warranted on medical grounds but was promoted by alarmism and fearmongering from media, academic economists, public servants and all forms of government. Holden–Preston assume a 10 per cent fall in GDP this year alone, with no long-term effects and a very conservative cost of the COVID-19 crisis of $180 billion but argue, inconsistently, that this grossly overestimates the cost of shutting down as voluntary social distancing would have been costly even without forced closure of much business activity. Might not voluntary social distancing have saved 225,000 lives even without lockdown? Paul Frijters (May 18, 2020) argues persuasively that the true cost of the global pandemic on Australia is likely to be six times higher than that provided by Holden–Preston, making it $1,080 billion.

Holden–Preston, having already argued that voluntary social distancing was going to cost 225,000 lives without forced closure, it is hardly consistent to argue that half the total cost costs would have been incurred anyway. Hence, according to the Holden/Preston analysis, we are left with a net cost of $90 billion from the shutdown but no sign of any benefit as voluntary social distancing, international quarantining, testing, and tracing would have done the job anyway at far lower cost. Their entire $1.1 trillion, or more credible $55 billion, benefit from lockdown is vacuous.

 

The payment of $260 billion to stop people working is far from costless

Holden–Preston then argue that a $320 billion (16.4 per cent of GDP) cost of supporting the economy during the compulsory shutdown is not a cost but simply a transfer of resources from one part of society to another. Since it is paid for initially by borrowing, the immediate impact is on the young and future generations. While this figure comes from Josh Frydenberg (2020, April 15), a $60 billion overstatement in the government’s JobKeeper estimate means that it is actually lower at $260 billion once this error is corrected.

So we learn that this sizeable boost to the social security budget to pay about three and a half million people to quit work and perhaps do nothing at home comes at no cost, other than “the economic distortions coming from raising the revenue to service the spending”. In fact, we learn from Holden–Preston that this cost is likely to be “tiny” as it will simply raise our international debt obligations at a time when real interest rates are low.

Suppose we have two otherwise identical workers, each creating equal value of $1500 per fortnight, but one is employed in an “essential service” and the other is not. The latter is placed out of work by shutdown orders and receives a JobKeeper payment of $1500 per fortnight. Not only does GDP fall by $1500 per fortnight due to the forced lockdown but the essential worker is now taxed $1500 per fortnight to support the now unemployed person in idleness. Since he cannot afford to pay the tax, the essential worker joins the inessential worker in idleness. The cost of the lockdown has now doubled to $3000 per fortnight. Hence, I cannot agree that a policy of paying people not to work is “costless”.

If adding debt is essentially “costless”, I am puzzled as to why we have taxes at all, since these are highly distorting and come at huge cost. Why not go one step further with this costless funding and pay the entire nation not to work? What is wrong with zero GDP? Surely, everyone would be better off if we exploited unlimited international borrowing capacity. Despite what one might infer from these statements, taxpayers will need to be slugged this additional $260 billion cost in a year in which the budget was supposed to be in surplus for the first time in decades.

One can identify some benefit from JobKeeper subsidies, as they retain a link between employer and employee. It is the lockdowns which have forced about three and a half million people into idleness. According to Australia’s CMO, this outlay has saved 14,000 lives at a cost of a sizeable $19 million per life, but in reality, probably close to zero lives.

Yes, in a world in which resources are essentially free, why worry about who is going to meet the largely unnecessary bill of $260 billion or $10,200 for every Australian man, woman and child? There is an upside for the non-economists in our midst. If resources are free, then there is no need to employ any economists and nor to train them. I find it surprising that a large number of top economists should argue that they are either redundant or perhaps should be made redundant.

 

Should we be concerned with the additional 750 to 1500 suicides each year?

According to the May 7 statement from the Australian Medical Association, between an extra 750 and 1500 more suicides may occur annually, in addition to the 3000-plus lives that are lost to suicide already every year, due to the expected increase in job loss and business failure arising from the shutdown. Could simply fear of the virus itself generate a sizeable loss of life from suicide? Very unlikely. The virus could have been presented simply as yet another form of flu that would affect a small vulnerable portion of the population but would be extremely mild or unnoticeable for the bulk of the population.

Holden–Preston argue that these effects are small relative to the mass deaths of 225,000 people that they envisage but are unable to justify. Moreover, from the perspective of deaths, they envisage economic crises as being beneficial, as there are fewer deaths in the workplace and on the roads. Yes, almost certainly the mortality rate has fallen greatly during the COVID-19 pandemic with millions of people forced out of a job and travel largely banned. Would they wish to live in a COVID-19 world permanently, or do they favour more Great Depressions with 50 per cent unemployment, since fewer die on the roads or in the workplace?

Holden–Preston have a simple message: “The shutdown wins”, and they believe that there are high risks from relaxation of restrictions in the absence of a vaccine.

To the contrary, Holden–Preston are simply alarmist, frightening the public with entirely discredited pandemic modelling in which they argue that mortality from COVID-19 is far worse than the devastating Spanish flu of 1918-19 and would kill nearly a quarter of a million Australians if the economy was not locked down. Yet the current world COVID-19 death toll would have to rise by a factor of 202 times to reach their estimate of seventy million global deaths in the absence of lockdown.

 

At great economic cost, Australia has failed to generate herd immunity

It would be a mistake to think that Australia and Taiwan, and all the other countries that have employed similar strategies, have got off lightly from COVID-19 by the simple expedient of banning the entry of non-citizens and early quarantining. Quarantining is exceedingly disruptive and impossible to sustain for any length of time.

I agree with Paul Frijters (May 14, 2020) that it is likely Sweden will emerge from COVID-19 better prepared than many other countries due to the creation of at least some herd immunity. Herd immunity does not rely on everyone being exposed to the virus. Rather, it relies on enough of the young and healthy being exposed with sufficient antibodies such that the elderly and vulnerable are protected from it. This would be especially important if it proves impossible to develop a vaccine in reasonable time. While Sweden may suffer because of the decline in the global economy, unlike most economies it has not deliberately forced millions into potential penury.

We can be sure that Governor Cuomo in New York and authorities in Belgium have exposed a sizeable portion of their populations to the COVID-19 virus, making “second wave” attacks less likely when borders reopen, as they must. However, they will never be “winners” in an economic sense because, unlike Sweden, they locked down the most productive while not taking care of the vulnerable.

 

Conclusion

Our actual current death toll of 102 would have been far lower if we had earlier implemented the quarantining, tracing and testing methods so successfully employed by Taiwan with their voluntary social distancing. Forced lockdown in a highly responsible society such as Australia’s yields no lives saved but huge and devastating economic costs and future deaths arising from economic despair. According to Australia’s CMO, some lives have been saved at a cost of $19 million per life, but this is a gross understatement of the cost per life. The sooner we cease the lockdowns and travel restrictions, while retaining voluntary social distancing and protecting the vulnerable, the better.

    A reasonable assessment on how many lives have been “Saved” by the lockdown measures can be made by comparing figures with 2009 Swine Flu. Then there were 38000 swine flu cases for 191 deaths (no mass hysteria then!). Given a similar R0 value to Covid then with just level 1/2 restrictions we would likely have seen about the same number of covid cases. So based on current mortality (About 9000 cases for 106 deaths) for 38000 cases would expect about 106 x 4.2 = 447 covid deaths. So far then measures have saved 447-106= 341 lives. At a cost of $300,000,000,000/ 341 = $879M each. Astonishing!!

    >”Spanish Flu died out by itself and I dont know why”

    That particular virus eventually mutated to a strain that our immune systems could deal with. All of the corona viruses evolve like this but the time span is not predictable.

    My experience with viruses tells me that not all the copies, say…. 1,000,000,000,000,000,000,000,000+ are going to mutate in the same direction at the same time, become incompetent, and thus die out. Let us look at a virus I know well – HIV, originally GRID [gay related immunodeficiency].
    1% of Europeans are naturally immune to HIV, having being born with homozygous mutated chemokine receptors [first discovered by me as the result of a search for novel cellular antigens]. Suppose the whole world turned gay. Then 1% of Europeans would be left alive. HIV and all susceptible humans would be history.
    So, I suspect, but cannot prove, that Spanish Flu ran out of hosts, and thus Spanish Flu likewise died out.

  • pgang

    T B Lynch, given enough time a corona or flu virus will evolve into a human being. Then they will be a danger only unto themselves.
    Or it could simply be that enough deleterious mutations accumulated within the virus to result in a form of genetic entropy, with decreased functionality resulting in catastrophically low adaptability. https://tbiomed.biomedcentral.com/articles/10.1186/1742-4682-9-42
    A crazy, heretical idea, I know. Only a lunatic would think such a thing. Clearly the first scenario makes much more sense.

  • Elizabeth Beare

    The statistical phenomenon of reversion to the mean will generally see a virus attenuate to the less damaging variety over time. All epidemics have their curve and then the attenuated disease becomes endemic and less harmful. Herd immunity helps too as the virus devolves in virulence the fewer the chances it has of making a transfer. Very virulent viruses kill their hosts and they die too.
    Immunity with Corona viruses is not secure, hence we are all open to catching and re-catching common colds, but a basic level of immunity exists so that each cold is fought off, with the main issue, as with the more damaging influenza, being secondary bacterial infections. Herd immunity is what we must eventually move towards; a Cov-2 vaccine is likely to be needed yearly, as with influenza, it may be ineffective, and it is unlikely to cover whole populations world-wide or locally.
    I would like to see a major effort in Australia to test for immunity rather than putting all of the focus on testing for cases and creating media panic over them. We would get a clearer picture then of where we are, especially given that new research suggests that we can increase the figure revealed by immune testing because some who have been exposed have used their T-cells to repel the virus even before mounting an immune response.
    Why are we not doing testing for population immunity as has been done in the US?
    If it were to reveal that we have little or no population immunity, then we are sitting ducks, and should recognise that by opening up we increase prevalence and herd immunity and avoid the cycle of lockdowns. We should now be able to rely on improved treatments to cope with any burden of illness from Covid-19. Sitting behind a continental wall in today’s world is madness except for creating initial preparedness to flatten an expected curve.
    Are politicians scared of immunity testing because they have spent so much money per saved life?
    Someone should tell them further lockdowns will only make this figure per life saved much worse.

  • Citizen Kane

    Add to this analysis that even ‘professor pants down’ admitted in recent UK parliamentary inquiry that statistically, 66% of those elderly victims of this virus would have Died within a year anyhow from their age related morbidities. Parts of Europe and the US are on the precipice of herd immunity which will begin to flow through in case loads by August. At which time these countries will be emerging out the other side of this pandemic while Australia will remain just at the beginning.

    This, along similar lines, re herd immunity stats, is worth reading too. Forget the link being off-guardian. It has some very sensible figures on death rates and the epidemic curve, very well worth pursuing. I’d say that there is now a fair amount of scientific acceptance that lockdowns are not necessary, indeed harmful except in the early epidemic curve stage to flatten it. The trouble now is convincing the terrified populace and pollies that this is the case.
