The Plague, the Spanish Flu, and the Coronavirus: Equivalence and Progress in Infectious Diseases

History forgotten is history to be repeated, for evolution occurs over such vast oceans of time that for our purposes, human biological nature is fixed. Yet history kept fresh can permit progress such that the species is better equipped to combat problems such as pandemics. At the time of the coronavirus pandemic of 2020, serious comparisons to the Spanish Flu of 1918 and the Black Death of the fourteenth century were lacking in the American media, including by public health officials and government officials even as claims of vague equivalence were made. Such claims, I submit, were erroneous. In fact, they did more harm than good by instilling excessive fear in the population.

Hearing the coronavirus being referred to as a plague on National Public Radio in the United States, I instinctively bristled at the assumed equivalence. A plague is a contagious bacterial disease with a high mortality rate. Coronavirus is a virus rather than a bacterium. The Black Death was a plague pandemic that “devastated Europe from 1347 to 1352 CE, killing an estimated 25-30 million people.”[1]  Paris buried 800 dead each day of the peak, or apex, there. “On average 30% of the population of affected areas [in Europe] was killed, although some historians prefer a figure closer to 50%, and this was probably the case in the worst affected cities.”[2] In 2020, two months after the first recorded death from the coronavirus in Europe, 97,000 people there were dead. The global mortality rate of coronavirus as of March 3, 2020, according to the World Health Organization (WHO), was just 3.4%, which is much closer to the 1% from seasonable flu.[3] Therefore, the coronavirus pandemic was not a plague.

The coronavirus pandemic was also publically likened to the Spanish Flu, which hit the U.S. in 1918. At least both were viruses, unlike the Plague. “The Spanish flu of 1918 lasted only a few months but took an estimated 50 million to 100 million lives around the globe, including 675,000 in the U.S.”[4] Ten days short of two months since the first death from the coronavirus in the U.S., 38,917 people were dead from the disease and less than 5% of the population had been infected. Worldwide, at least 158,000 people had died.[5] Clearly, the two pandemics were not equivalent. The assumed equivalence in the comparisons in 2020 demonstrates not only ignorance, but also a lack of interest in acquiring even a bit of historical knowledge so as to make tolerable comparisons.

In spite of historical knowledge being available and there being advances in knowledge, weaknesses of our species exerts a countervailing wind on the road of progress. The Spanish flu itself may not have been more virulent, however, because medical and public-health knowledge was so significantly less in 1918 than a century later. To put the two eras in perspective, model-T cars were on the road in 1918, whereas electric (and hybrid) cars were being driven and self-driving cars were being tested by 2020.

Parades and “other large public gatherings were common, contributing to the spread” of the Spanish Flu.[6] American governments facing the coronavirus pandemic prohibited or recommended people to maintain a physical distance from each other and stay home as much as possible (e.g. shelter-in-place orders). Retail businesses either shut voluntarily or by government order. Medically, antibiotics “to treat secondary bacterial infections that often accompany the flu had yet to be discovered” by 1918.[7] In addition to antibiotics, physicians in 2020 could put patients struggling to breath on ventilators.

It cannot be assumed, however, that people in 2020 could not have improved their chances of staying healthy by learning more about the 1918 societal protocols. During the Spanish Flu, it was thought “that keeping windows open would deter the spread.”[8] Trolley cars in Cincinnati, Ohio displayed fliers encouraging the practice, “which was utilized nationwide.”[9] In contrast, bus drivers in Phoenix, Arizona kept the bus’s narrow upper windows closed during the coronavirus pandemic a century later. Missing the larger point, the bus company’s management claimed that even open slits were unsafe because passengers could throw small objects out of the buses. Even though medical knowledge was clear that the coronavirus stays airborne relatively long due to its small size among flus and could even be transmitted by normal breathing, the bus company in the desert did not bother to read up on how trolley companied had dealt with the pandemic in 1918. Nor did the passengers figure that physical distancing applied to getting on the bus (i.e., giving deboarding passengers some space). In grocery stores in Phoenix, employees and customers alike overwhelmingly ignored the store policies on keeping at a distance from other people. In spite of the signs and announcements, the managements did not have control over their own employees.

Arizona at the time had one of the worst public education systems in the U.S.; even bad judgment could be traced back to this factor. Perhaps it is too idealistic to assume that everyone can be educated enough to reason his or her way to better secure even self-interested self-preservation. Even with historical knowledge and advances thereof available, human nature presents a limit as to how much actual progress can be made against infectious diseases.

Oceans Arising on Edifices of Arrogance

A study published in late November 2012 in the journal Science estimates that the melting of ice sheets in Antarctica and Greenland had raised global sea levels by 11.1 millimeters (0.43 inch) since 1992. That represents one-fifth of the total sea-level rise increase in that period. Other contributors include the expansion of the sea water from warming, and the melting of glaciers, as for instance on mountains. In the 1990s, melting of the polar ice sheets in the Antarctica and Greenland was responsible for about 10 percent of the global sea-level rise, but by 2012 the effect had risen to 30 percent.[1] The study does not, however, uncover the underlying cause, or association, lying in a complexity in human nature itself. Our species has vaunted to the top of the food chain and leveraged a brain capable of engineering technological advances that would have seemed magical even just in the nineteenth century, and yet we seem hard-wired to accelerate our course to a self-destructive extinction. This lack of balance is reflected in the increasing extremes in the global climate. In this essay, I begin with the study and steadily work toward uncovering the underlying, subterranean culprit.

In Greenland, melted ice, or water, headed to the Atlantic Ocean. NYT

The study can be interpreted as essentially “firming up” what had been left to guesswork hitherto. “It allows us to make some firm conclusions,” Andrew Shepherd of the University of Leeds said. “It wasn’t clear if Antarctica was gaining or losing ice. Now we can say with confidence it is losing ice.”[2] This is significant because there are hundreds of feet of sea-level rise in the combined ice of Greenland and the Antarctica, and even that sort of rise could occur in even just two centuries. Unlike ice in the sea melting, water from land-ice is added to the sea and thus is particularly salient in the rise in sea-level.
Although correlation is not necessary causation, global emissions of carbon dioxide were at a record high in 2011, having jumped 3% from the previous year. The international goal of limiting the ultimate warming of the planet to 3.6 degrees (F) was all but disregarded at the time as unrealistic, according to researchers at the Global Carbon Project. Slowly falling emissions in some of the developed economies, including the U.S., were more than matched by continued growth in developing countries like China and India. Coal was growing fastest, with related emissions jumping more than 5 percent in 2011 from the previous year.[3]
Moreover, the level of carbon dioxide, the most important heat-trapping gas in the atmosphere, had increased 41% since the beginning of the Industrial Revolution. Meanwhile, the temperature of the planet increased about 1.5 degrees (F) since 1850. The New York Times reports that scientists expected at the time of the release of the 2011 figures that further “increases in carbon dioxide” would “likely . . . have a profound effect on climate, . . . leading to higher seas and greater coastal flooding, more intense weather disasters like droughts and heat waves, and an extreme acidification of the ocean.”[4] The volume of carbon dioxide in the atmosphere in 2013 was 396 parts per million, 2.9 ppm higher than in 2012; this represents the largest year-to-year increase since 1984, when reliable global records began.[5] As a result, "(c)oncentrations of nearly all the major greenhouse gases reached historic highs in 2013, reflecting ever-rising emissions from automobiles and smokestacks but also, scientists believe, a diminishing ability of the world's oceans and plant life to soak up the excess carbon put into the atmosphere by humans."[6] Accordingly, climatologists were predicting more accelerated ice-melt.
To be sure, distinguishing a causal connection from the sort of cycle that was responsible for Greenland being green in Mediaeval times has been the fulcrum of much controversy and debate; it is not as though scientists can treat one earth by increasing the carbon dioxide in the atmosphere while leaving another earth as a control-group and measure the differing climatic consequences. As the philosopher David Hume argued in the late eighteenth century, we actually know much less about cause and effect than we think we do. The human brain naturally that’s a strong positive correlation accompanied by a logical rationale as good enough to pronounce a causal relationship.
Regardless of whether our use of fossil fuels is a contributing factor in the melting of the ice-sheets, that the sea-level was rising even in 2011 and so much of humanity lives within fifty miles of a sea-coast suggests that major dislocations will undoubtedly be necessary within one or two hundred years, and perhaps even sooner given the record-high level of carbon dioxide in the planet’s atmosphere in 2013. As much as a third of Florida could be underwater again—whether it eventuates as a result of a natural climatic cycle or carbon dioxide emissions, or both. That the acceleration in the ice-sheet melting reported in 2012 was five times that which scientists had supposed earlier suggests that the data in from the following year may result in even more dramatic headlines. That the C02 and methane (from leaks in wells and distribution as well as from permafrost melt) levels were not only increasing, but doing so at unprecedented rates, suggests that we humans have literally outdone ourselves. It seems a fantasy to expect prudent measures that would obviate beforehand even just some of the anticipated damage. Even in the wake of Hurricane Katrina, the U.S. Government could have given Louisiana a financial incentive to rebuild the city further inland, above sea-level. That would have been an easy decision compared with what to do about Manhattan, and yet the unquestioned, knee-jerk response was to rebuild on site.
Accordingly, even the study on ice-melt reported in late 2012 and the report in 2014 of the record increase in C02 in the atmosphere were unlikely to affect public policy significantly, at least in the United States. Enabling such negligence, Andrew Shepherd of Leeds said in 2012: “The signals suggest there is no immediate threat.”[7] Meanwhile, the carbon emissions were actually increasing from the previous year. This represents two degrees of separation from a reduction. The emissions targets in the UNFCCC agreement signed in 1992 had included stabilisations at 1990 levels for some countries and reductions for others by the year 2000.   In other words, we as a species seem pretty clueless, even as we promote ourselves being of the highest and most developed species. 
We are, it can be said, a species of today. The stock markets demonstrate this innate propensity clearly enough. For a complex organism not known for quick evolutionary adaption to a changing environment, it is dangerous to be so “hard-wired” for today when our artifacts collectively can shift a planetary equilibrium beyond its natural cycle. It is not a given that we will be able to rely on our prowess at technological development to make up for our convenient habit of looking on and even making a situation worse. I have personally felt this in momentary lapses of my new-found better diet when I eat one after another chocolate cookie after having fallen with one. My mind succumbs to the fallacy that in having lapsed, might as well open the flood-gates. The next morning, I make myself go running, as if the presumed cause-effect relation might prevent any future lapses. Nietzsche may have been right in suggesting that thoughts are really instinctual urges and reasoning is their tussling for dominance.
As Mark Twain observed, speaking through an angel in The Mysterious Stranger, “Man’s mind clumsily and tediously and laboriously patches little trivialities together and gets a result—such as it is.”[8] Yet so conceited is that mind, and in other matters too. In spite of having a moral sense, and perhaps because of our knowing right from wrong, our “paltry race [is] always lying, always claiming virtues which it hasn’t got.”[8] From an angel’s point of view, homo sapiens—arrogantly self-named here as the “wise man” species—can only be “dull and ignorant and trivial and conceited, and so diseased and rickety, and such a shabby, poor, worthless lot all around”[10] as to be met with utter indifference from the angelic perches so different—the pathos of distance being hollow rather than filled with empathy or even sympathy.[10] Twain’s angel does not mince words. Humans “have nothing in common with me—there is no point of contact; they have foolish little feelings and foolish little vanities and impertinences and ambitions; their foolish little life is but a laugh, a sign, and extinction.”[12] It is not merely the staying power of the moneyed commercial caste that moves us as a species to our own extinction; all of us are complicit.
We have built our mammoth edifices and modern conveniences on such a scale, and we use them as if we were junkies on a drug-fix that we have outstripped our own capacity as a species even to mop up after ourselves. This vulnerability becomes truly dangerous now that we are capable of having a significant impact on the planetary ecosystem, including its atmosphere. Even so, we continue to single our species out as “Made in the Image of God,” and as we preach our moral sense, ignorant of the probability that a more intentionally cruel and self-destructive race has never roamed on the land or swam in the sea. Our reckless conceit, it would seem to all outward appearances, is in such denial of its own existence that we naturally assume we cannot be wrong—that we affirm with such factuality, “I know what I know.” If only the ice on this towering edifice would melt from global warming; if only we could be so lucky.

The Age of Humans: Snuffing Our Species Out

With California entering its fourth year of severe drought and the planet having its warmest August and September since records began in 1880, one scientist at NASA’s Institute for Space Studies said in 2014 that the warm data points “point toward the long-term trends.”[1] At the time, scientists were already claiming that the planet had entered a new era—that of the Anthropocene—noted for the impact of the homo sapiens species in altering Earth. The implications are profound, even if the huge shift has not fully registered in human consciousness.



According to one geologist speaking in 2014, “humans have become a geologic force on the planet. The age we are living [in now] is really distinct.”[2] Yet we might be too close to it to recognize the distinctness, and so our elected representatives may not feel emboldened to craft public policy to the new reality. The resulting vulnerability has scarcely been contemplated. John Kress, the acting undersecretary of science for the Smithsonian Institution highlighted the mammoth nature of the change. “Never in its 4.6 million-year-old history has the Earth been so affected by one species as it is being affected now by humans.”[3] In addition to climate change, the impact extends to ozone loss, disruption of nitrogen and phosphorous cycles, the acidification of oceans, endocrine disruptors, and deforestation.[4] I submit that we are not even aware of other footprints that could make the planet potentially uninhabitable for our species one day; for without much of a recognition of the new era, we cannot expect to have much of a grasp on the breadth of our species’s impact on the planet.

In his book, Steps to An Ecology of Mind, Gregory Bateson approaches ecological principles from the standpoint of general systems theory. That is to say, he stresses the system-qualities of an ecosystem. His notion of a maximizing variable is relevant here. Such a variable maximizes without taking a break. A species in an ecosystem qualifies as a maximizing variable if that species continues to increase, unhampered even as it butts up against the semi-permeable membrane of an ecosystem’s constraints. When such a species “breaks through” what its ecosystem will tolerate, the state-state equilibrium is disrupted and the ecosystem must “find” another equilibrium. The new resting point may or may not include the species.

Our species is indeed a maximizing variable, with a population of over 7 billion as of 2014. In his pathbreaking work on populations, Malthius postulates that an over-populated species is vulnerable to famine, epidemics, and war. Studies using rats have demonstrated the theory in action. Yet in the Anthropocene Age in which we live, we can add a more “macro” consequence—that of being vulnerable to the planet becoming uninhabitable to our species. As Nietzsche brilliantly writes regarding how people can unintentionally discredit their own conception of God and thus effectively ruin it, we may have blood on our hands and yet not realize that we ourselves have done the deed. Like light coming from the farthest star, awareness of our large-scale impacts already committed has not yet reached us.

Indeed, the Earth’s equilibrium was already on the move in the early 2010s and yet we struggled to separate this out from “natural fluctuations.” Without much recognition of the new era and even less comprehension of the impacts and how serious their respective consequences would likely be, our species could indeed be heedlessly maximizing itself to extinction without realizing it. In genealogical time, our genes could be outstandingly successful in terms of replication only for a short burst of time before burning out like a candle’s flame enjoying too much wick.

Humanity Getting Ahead of Itself: A Mass-Extinction Event Already Underway

Around 252 million years ago, the “Great Dying” took out 90% of the world’s species. About 66 million years ago, a meteor caused the extinction of three out of four species, including those known to us as dinosaurs.[1] After 1.8 million years of existence, our own species is triggering yet another mass extinction event, according to a study in the journal Science by Stuart Pimm and Clinton Jenkins. According to Pimm, species are now going extinct at about ten times faster than scientists had thought. Prior to the arrival of homo sapiens (i.e., our species), the extinction rate was about 0.1 out of a million species per year; as of 2014, the rate had climbed to 100 to 1000 species per 1 million.[2] Behind this evolutionarily abrupt bump is not only the complicity of our species, but also unforeseen consequences that could easily take homo sapiens out of the equation.

Beyond the positive correlation of our species and the rate increase, Pimm and Jenkins posit a causal relationship, pointing in particular to habitat loss due to the territorially expansive attribute of an expansive human population globally. Climate change and overfishing, both of which are related to the increase in the human population, are also salient factors.

As observable as this leap in the extinction rate is, the implications may elude our cognitive grasp, and thus be especially dangerous for our species. In other words, our collective failure to manage our population level may result ironically in the downfall of the species.
In another study in 2014, Rodolfo Dirzo points to the overexploitation of resources and habitat destruction as examples of human activities responsible for the rise in the extinction rate of species. Since 1500, 322 terrestrial vertebrates had gone extinct, with the remaining species declining in numbers by an average of 25 percent; for invertebrates, the typical decline in population is a whopping 45 percent.[3] With these stark changes naturally come unforeseen consequences. “We tend to think about extinction as loss of a species from the face of the Earth, and that’s very important, but there’s a loss of critical ecosystem functioning in which animals play a central role that we need to pay attention to as well,” Dirzo said in a statement.[4] Even amid all of our advanced technology, we are a species that lives within ecosystems; the collapse of such a system means all bets are off in things like food supply that we take for granted.

For example, “(w)here human density is high,” Dirzo continues, “you get high rates of [animal decline], high incidence of rodents, and thus high levels of pathogens, which increases the risks of disease transmission. It can be a vicious circle.”[5] Rodents and pathogens can of course hit our food sources as well as us. Ironically, our own technological advances can exacerbate the potential harm.

Air transportation, for example, could turn the massive spread of the Ebola virus in Africa during 2014 into a worldwide pandemic. Even as we were congratulating ourselves on finally accepting what climatologists had been telling us for over a decade concerning the harmful impact of our carbon-dioxide emissions on the planet’s temperature, we were blissfully unaware of the contribution being made by methane, a gas with ten-times the “greenhouse” effect as carbon dioxide, through leaks in extracting and distributing natural gas—the “clean” gas—as well as in the melting of the permafrost around the Artic. With the kind of scales to which our technology can be applied, both the unforeseen impacts and the damage can be much greater than we know. Put another way, we have increased the size of our footprint so much as a species that we cannot get our minds around all of the unintended consequences.

In short, we have gotten too big, both in population and the scales in which we chose to operate, for our own good. While our genes are doubtlessly quite pleased with their success in replication, they are clearly not smart enough for their own long-term survival. The human brain seems naturally inclined to assume the absence of unforeseen implications rather than holding as a default that they exist “out there” even if we have not yet detected them. As superior as our species’ brain is, it sports a major flaw in having or adopting a schizogenic (i.e., a variable that maximizes itself without limit) mentality rather than one that is homeostatic, or steady-state (e.g., ecologizing).[6] This explains why we have been so hesitant as a species even to reduce the increases in our carbon footprint, let alone bring it down to a level at which the warming of the planet will allow for the continued survival of our species. In short, we tend to be all about maximizing—even as if it were an end in itself—in line with our greed and hubris rather than valuing the achievement of equilibrium in line with, rather than puncturing, the ecosystems within which we live and breathe.
