Since the fall of the Western Roman Empire, there have been three major bubonic plague epidemics, which afflicted large segments of the population in the continuous Eurasian landmass and North Africa. Death quickly followed the trade routes of the times. The death toll is almost incomprehensible. The Plague of Justinian (6th Century A.D.), the Black Death (14th Century A.D.), and the Bubonic Plague (1665-1666, which coincided with the Great Fire of London) caused an estimated 137 million dead in a world much more sparsely populated than it is today.

To make matters even worse, one must also remember that these pestilences assailed and ravaged mankind at a time when the average life span was short --- less than two decades during the Middle Ages. Survival to age five was a miracle not only because of endemic disease, dirt and filth, concomitant poor hygiene and sanitation, but also because of the primitive state of medical knowledge. Pestilential disease thrived under such conditions. Moreover, during the Middle Ages, bathing and cleanliness, even in the upper classes, was a rarity, being viewed as unhealthy as well as irreverent --- acts of vanity in the face of God.

Epidemics in the Graeco-Roman World

During the Peloponnesian War (431-404 B.C.), fought between ancient Athens and Sparta and Athenian Plaguetheir allies for supremacy of the Greek world, the Athenian army had to withdraw behind the safety of its city walls after a successful invasion was carried out by Spartan forces. Shortly after, in 430 B.C., the historic Athenian Plague broke out decimating a quarter of the population within the city. The supreme Athenian statesman and leader, Pericles (c. 495-429 B.C.), succumbed to this epidemic after seeing his own sister and two sons contract the disease and die. Historians are not completely sure this pestilence was really the plague. It's possible it was some other disease such as smallpox.

Plague or otherwise, the historian Thucydides left a poignant account of this catastrophic time recounting that the Athenians, "...fear of gods or law of men there was none to restrain them. As for the first, they judged it to be just the same whether they worshipped them or not, as they saw all alike perishing; and as for the latter, no one expected to live to be brought to trial for his offences." The historians Frederick F. Cartwright and Michael D. Biddiss in their book, Disease and History, added that Thucydides lamented that "the most staid and respectable citizens devoted themselves to nothing but gluttony, drunkenness and licentiousness."(1)Antonine Plague

Likewise, during the reign of the great Stoic philosopher, the Roman Emperor Marcus Aurelius (emperor, AD 161-180), a great pestilence was brought back to Rome (AD 166-167) by the victorious legions which, led by Lucius Verus (co-emperor, AD 161-169), had been pushing back the invading Parthians pressing on the eastern frontiers of the empire. This pestilence caused the death of approximately 25 million people and was most likely smallpox. Co-emperor Lucius Verus was eventually afflicted and, like Pericles nearly six centuries earlier, succumbed to the disease. One can only imagine the devastation of these epidemics in the midst of wars: the loss of loved ones; the breakdown of societal, civic and learning institutions; the breakdown of law and order, particularly in the countryside where the population was at the mercy of barbarian hordes and brigands; goods not produced; services not rendered; lands not cultivated; crops left unharvested, etc.

The Plagues of the Middle Ages

At the peak of his reign, after accomplishing major political, judicial, and military successes, Justinian, emperor of the Eastern Roman (Byzantine) Empire, suddenly faced an old, ferocious enemy of mankind: pestilence. The bubonic plague, which struck in A.D. 540, is justifiably the worst recorded pandemic to ever afflict humanity. Any hopes of reestablishing the Roman Empire were dashed. Records regarding the dimensions of the devastation and the untold suffering and death were carefully kept by Justinian's chief archivist and secretary, the celebrated court historian, Procopius.

Four Horsement of the ApocalypseIf one considers the dimensions of the devastation of the bubonic plague of the 6th Century in the midst of the Dark Ages --- the savage imperial wars waged against the barbarian hordes, the terrible famines, the ubiquity of death and destruction, and finally the unleashing of this cataclysmic epidemic --- it should not be difficult to imagine that the people at the time believed that they were being scorched and ravaged by the dreaded Four Horsemen of the Apocalypse, as described in the biblical book of Revelation 6:8, "And I looked, and behold, a pale horse; and his name that sat on him was Death." (photo, left: Four Horsemen of the Apocalypse ca. 1497-98 by Albrecht Dürer, woodcut)

The Emperor Justinian, defeated by the cataclysm of the bubonic plague, saw with horror the disease demolishing his once invincible armies and killing his generals and soldiery alike faster than the wounds inflicted on the battlefield. Entire villages and towns were obliterated; the apocalyptic visitations were considered divine retribution from God as punishment for worldly sins. Demoralized and disheartened, he returned to his capital, Constantinople, only to find that there, too, the terrifying pestilence was relentlessly killing his people, rich and poor, regardless of kinship or station in life. The mortality in the city at this time was approaching 5000 deaths a day and would eventually reach an all-time high of 10,000 deaths daily. In despair and in need to fill the void, Justinian sought solitude, and the comfort and solace of religion.

The learned physicians of Justinian's day, who at the time followed the precepts of Graeco-Roman medicine, were discredited because their nostrums proved useless at the time of the cataclysm. Instead, the people turned for consolation to monastic medicine and the teachings of Christianity. The Christian church did rush in and, as best it could, tried to fill in the medical void. The monks in the monasteries quickly became the spiritual as well as corporeal healers by tending both to the needs of the soul and the requirements of the body. They used prayer and only the rudiments of physical or herbal medicine to console and heal the sick.

The humbling of the medical profession because of its impotence to control the plague of the 6th Century, essentially halted the advancement of medical knowledge for centuries. Medicine regressed, and disease in general was equated with vice and sin, rather than with filth, poor hygiene, and natural causes.

Yet, medicine was not the only profession in abeyance to disease. Other ancient professions, such as law, engineering, and the natural sciences (not to mention the liberal arts of the Greeks and Romans), were largely erased from the collective memory of humanity. All areas of human endeavor were doomed to intellectual dormancy. Progress stopped. The turning wheels of Western culture and civilization had ground to a shrilling halt as humanity became fully immersed in the Dark Ages. New hordes of barbarians were marauding and ravaging the West, while the plague was humbling the East.(2)Bubonic Plague

The great pestilence of the medieval period was the Black Death (1346-1361), the bubonic plague caused by the then highly virulent bacterium, Pasteurella pestis and transmitted generally by the black rat, Rattus rattus. The plague is passed from rat to rat by fleas. Man becomes infected when he unwittingly interrupts the infectious cycle by being bitten by an infected flea. Once the infection takes place, Pasteurella pestis causes disease by septicemia or by invasion of the lymphatics, spreading in the body with two types of presentations. The pneumonic form of the plague is most ominous. In this highly contagious acute form, the disease may also be transmitted directly from person to person via the pulmonary route (i.e., aerosol droplets), and death takes place rapidly. It was said that one day a person would cough-up phlegm and then be dead by the fifth day.

The predominant form of the disease, though, was the subacute bubonic form, characterized by severe involvement of the lymphatic system with the formation of buboes (from which the disease takes its name). The buboes are swollen, infected lymph nodes, most commonly involving the inguinal and/or the axillary lymph node chains. The buboes may grow to a significant size to erode through the skin and spontaneously burst, draining infectious purulent material. Death came in a slower and more agonizing way. Very few so afflicted lived beyond 10 days, and the affliction still carried a mortality of 90 percent.

The epidemics of bubonic plague were veritably history's greatest scourges. In the case of the Plague of Justinian, the epidemic ravaged the populace for five decades between A.D. 540 and Great Plague of London590 and, although precise figures are not possible to ascertain, it may have caused the death of one-third of the population. The Black Death, which peaked in 1347-1348, also inflicted morbid devastation and rampant desolation and death in medieval Europe and exacted a death toll of perhaps 27 million lives and lasted 15 to 20 years. The Black Death seriously disrupted the social and economic fabrics of Western society. In Europe, the people began to question religion and faith and looked instead for answers in the emerging science of the medieval universities sprouting up throughout Europe, the reverse of what took place after the Plague of Justinian. Moreover in England, large tracts of land were left uncultivated because of the lack of a work force. Suddenly, labor because precious. Workers demanded higher wages and poor peasants disappeared, at least for a time, and were replaced by more prosperous farmers and landowners, threatening the very structure of feudal society.

The Great Plague of London, which assailed England from 1665 to 1666, at its peak killed 2000 Londoners a week but mercifully only lasted several months, coincidentally ending with the Great Fire of London.

The New World and Disease

With the discovery of the New World in 1492, infectious diseases, such as measles and smallpox were brought to the New World, wreaking havoc in the immunologically susceptible indigenous population. In return, the Europeans carried syphilis back to their homelands. Recently, there have been accusations of European genocide upon native populations of the New World. But, as the author wrote in Vandals at the Gates of Medicine: "This depopulation [of the Americas] was neither officially sanctioned, anticipated, or even intended by the Spanish or Portuguese authoritiesThese afflictions had more to do with the mingling of two very different and isolated cultures (which up to this time had not been in contact with each other) than with a deliberate act of genocide."(2)

In 1647, yellow fever appeared in the colony of Massachusetts assailing the population and killing many inhabitants. To prevent further spread of the disease, quarantine was implemented for the first time in the colonies. In 1665, the quarantine was extended to all ships coming from England to prevent spread of the bubonic plague that was then assailing London. In the eighteenth century, yellow fever reappeared in Philadelphia, particularly in 1793, decimating the population of that city. It is estimated that ten percent of the population died, and according to medical historian Howard W. Haggard, in his book the Doctor in History, "Philadelphia reseDr. Benjamin Rushmbled London in the days of the bubonic plague."(3) Many people fled the city but one doctor who stayed was Dr. Benjamin Rush (photo, right), an American patriot and one of three physicians who signed the Declaration of Independence in 1776. Dr. Rush indefatigably ministered to the sick with the treatments of the time, purging and bleeding, and became a popular hero.

Humorous medical historian, Art Newman, in his book The Illustrated Treasury of Medical Curiosa, described one such occasion: "[Dr. Rush's] coach was stopped at Kensington by a crowd of hundreds who begged him to visit their homes and care for their sick. Rush stood up in his curricle and addressed the throng. 'I treat my patients successfully by bloodletting and copious purging with calomel and jalop, and I advise you, my good friends, to use the same remedies.' Someone shouted, 'What, bleed and purge everyone?' 'Yes!' cried the doctor. 'Bleed and purge all Kensington!' "(4)

The Final Act in the Drama

The first case of cholera occurred in England in 1831. No explanation can be offered for why cholera, which had been confined to India as an endemic disease for at least 2000 years, suddenly burst forth as a worldwide affliction. We do know that up to the mid-nineteenth century, European cities were reservoirs of disease because of the ubiquity of dirt and filth and poor hygiene and sanitation. Newman recalled: "Down the middle of English streets ran a gutter or kennel into which garbage and refuse were tossed to fester in the hot sun"; and the great Anglo-Irish writer and satirist Jonathan Swift (1667-1745) parodied: "Now from all parts the swelling kennels flow, And bear their trophies with them as they go; Filths of all hues and odours seem to tell/ What street they sailed from by their sight and smell"(4)Dr. John Snow

Cholera reached New York in 1832 and subsequently spread to Mexico, Cuba, and the rest of the Americas. Credit should be given to the great English physician from Newcastle upon Tyne, Dr. John Snow (photo, left), whose work solved the problem of the transmission and prevention of cholera in 1849. A fine anesthesiologist and epidemiologist, Dr. Snow proved by scientific investigation that cholera is a water-borne disease, his research eventually led to the conquest of such epidemic diseases as dysentery and typhoid fever.

Snow's epidemiological studies were momentous discoveries, but they needed to be applied by his successors. Consider that still in the Spanish-American War (1898), the U.S. lost more soldiers to typhoid fever than were killed in the battlefields of Cuba and the Philippines.

In 1885, the French scientist Louis Pasteur (1822-1895) established a clear relationship between microorganisms and disease, formulated and proposed the fundamental principles of the germ theory of disease, and ended the vicious cycle of superstition, ignorance and disease. Pasteur finally demolished and put to rest the old theory of spontaneous generation that had held medicine back for centuries by convincingly demonstrating that living microbes caused not only fermentation but also putrefaction and disease.Louis Pasteur

It was Pasteur's (photo, right) systematized observations and experiments that clearly rejected the theory of spontaneous generation, which had dictated that disease arose from non-living things such as miasmas from marshes rather than living microbes.

The germ theory of disease was the Achilles heel of those old, furious enemies of humanity --- plagues and epidemics. Once scientific theory was put into practice with improved hygiene and sanitation, disinfection, and the use of antibiotics --- the old bacterial enemy was largely vanquished.(5)

Yet, infectious disease has not been eradicated. In modern times, the Influenza Epidemic of 1918 suddenly erupted and unmercifully killed 20 million people. Of those who survived, many later suffered unusual sequelae, such as atypical Parkinson's disease.

Thus, enemies of humanity, like viruses (e.g., human immunodeficiency virus [HIV] that causes AIDS), some protozoa (e.g., malaria, toxoplasmosis, etc.) and even infective particles made up of nucleic acids (i.e., DNA and RNA) and/or proteins, such as prions which are posited to cause such dreadful diseases as Jakob-Creutzfeldt disease and Mad Cow Disease --- are yet to be subdued. Medicine still has a lot of work to do in the struggle of humanity against epidemic illness, disease, and pestilence.

Ebola & Obamacare

Obama to send 3,000 troops to west Africa to fight Ebola

By Associated Press September 16, 2014

WASHINGTON (AP) — The Obama administration is ramping up its response to West Africa's Ebola crisis, preparing to assign 3,000 U.S. military personnel to the afflicted region to supply medical and logistical support to overwhelmed local health care systems and to boost the number of beds needed to isolate and treat victims of the epidemic.

President Barack Obama planned to announce the stepped-up effort Tuesday during a visit to the federal Centers for Disease Control and Prevention in Atlanta amid alarm that the outbreak could spread and that the deadly virus could mutate into a more easily transmitted disease...Ebola & ObamaCare

Rush Limbaugh October 6, 2014

RUSH: Well, yeah, that's another story. But this additional thousand, this was announced late Friday when it was supposed to be unnoticed. So now the total is up to 4,000. What I don't know, I haven't heard it explained -- maybe it has been and I've missed it. But how do uniformed military personnel fight Ebola? You can't shoot it. What are they gonna do? Are they basically there to enforce quarantines? Are they basically there to make sure that the infected do not escape wherever they are and spread it?

CALLER: I'm wondering if they're not over there to get infected. And what do you do with these people when you bring 'em back? I mean, if there's a high infection rate and you try and bring 'em back and put 'em into, say, military hospitals?

RUSH: ... I don't know if you were listening on Friday, but we had this author -- I can't remember his name now, and I wish I could. David something or other -- and he actually said, in his own politically correct way, that we bear the responsibility for these people in Africa getting this disease, and we can't turn our backs on 'em because of that.

He said the only reason they are there is because of American slavery. Liberia came to exist because of American slavery, and since they fled this country to escape the bonds of slavery and they set up Liberia, if it hadn't been for us, they wouldn't now be suffering from this virus, and so we can't turn our backs on them. We are culpable, in his way of thinking. If it hadn't been for us, if it hadn't been for slavery, there might not be Ebola. Now, he didn't say it in those words, but it's inescapable that conclusion. My point to you, Cliff -- and I know there are gonna be some people smirk at this.

David Quammen was the guy's name, and he's a well-known Ebola expert and has written books about it. And I'm telling you there are oddballs, there are people in this country -- do not doubt me on this, folks -- there are people in this country who believe what this guy said, that this is ultimately traced back to us because of our slavery and these poor people had to leave this country because it was so horrible here because of slavery and they established Liberia. Sierra Leone, by the way, was established by British African-Americans who fled slavery there, and if it hadn't been for that, they probably wouldn't have. So there are some people who think we kind of deserve a little bit of this. Make no mistake. That is leftist political correct thinking. It's always been around.

Obama & Ebola

"...But President Obama is very sensitive to being defined in any way by the borders of this country. I think he sees himself as a citizen of the world and sees Americans as having infected others with our deadly economic policies for a long time, thereby inflicting untold suffering on developing nations. To now lead the way to America insulating itself from a scourge sweeping the very countries he seems to think we have preyed upon could, of course, strike him (if only unconsciously) as profoundly unfair.Ebola Malaria

"I believe the president may literally believe we should suffer along with less fortunate nations. And if he does, that is a very dangerous psychological stance from which to confront Ebola. Let me say this plainly, as a psychiatrist who has studied this president only from a distance: In order for President Obama to keep thinking of himself as the leader of the world — and not just the free world — it may be that our boundaries must remain porous, allowing illegal immigrants and, potentially, even diseases to flow through them." — Fox News contributor Keith Ablow, October 15, 2014

Bubonic plague!

ANTANANARIVO, Madagascar (AP) — Local authorities in Madagascar say 20 people have died since last week because of what they suspect to be an outbreak of bubonic plague.

Police in the northwestern district of Mandritsara said Wednesday the deceased could not be treated in time. They say more than 20 others suspected of being infected are currently receiving treatment.

Madagascar's Health Ministry says the outbreak is not yet confirmed pending analyses of samples by the country's Pasteur Institute research facility.

The health research institute could not immediately be reached.

The plague, known as the Black Death, killed millions in Europe in the Middle Ages but is now extremely rare and can be treated. It is carried by bacteria that primarily are carried by wild rodents.
