Extensive Definition

Smallpox is an infectious disease unique to humans, caused by either of two virus variants named Variola major and Variola minor. The disease is also known by the Latin names Variola or Variola vera, which is a derivative of the Latin varius, meaning spotted, or varus, meaning "pimple". The term "smallpox" was first used in Europe in the 15th century to distinguish variola from the great pox (syphilis).
Smallpox localizes in small blood vessels of the skin and in the mouth and throat. In the skin, this results in a characteristic maculopapular rash, and later, raised fluid-filled blisters. V. major produces a more serious disease and has an overall mortality rate of 30–35%. V. minor causes a milder form of disease (also known as alastrim, cottonpox, milkpox, whitepox, and Cuban itch) which kills ~1% of its victims. Blindness resulting from corneal ulceration and scarring, and limb deformities due to arthritis and osteomyelitis are less common complications, seen in about 2–5% of cases.
Smallpox is believed to have emerged in human populations about 10,000 BC.
During the 20th century, it is estimated that smallpox was responsible for 300–500 million deaths. As recently as 1967, the World Health Organization (WHO) estimated that 15 million people contracted the disease and that two million died in that year. After successful vaccination campaigns throughout the 19th and 20th centuries, the WHO certified the eradication of smallpox in 1979.


Smallpox is caused by infection with variola virus, which belongs to the genus Orthopoxvirus, the family Poxviridae, and subfamily chordopoxvirinae. It affects mostly babies and young children. Variola virus is a large brick-shaped virus measuring approximately 302 to 350 nanometers by 244 to 270 nm, with a single linear double stranded DNA genome consisting of 186 kilobase pairs (kbp) and containing a hairpin loop at each end. The two classic varieties of smallpox are variola major and variola minor. The closest viral relative is molluscum contagiosum, which like smallpox, infects only humans. However, unlike variola species, molluscum infection is benign. The lifecycle of poxviruses is complicated by having multiple infectious forms, with differing mechanisms of cell entry. Poxviruses are unique among DNA viruses in that they replicate in the cytoplasm of the cell rather than in the nucleus. In order to replicate poxviruses produce a variety of specialized proteins not produced by other DNA viruses, the most important of which is a viral-associated DNA-dependent RNA polymerase. Both enveloped and nonenveloped virions are infectious. The viral envelop is made of modified Golgi membranes containing viral-specific polypeptides, including hemagglutinin.
Four orthopoxviruses cause infection in humans: variola, vaccinia, cowpox, and monkeypox. Variola virus infects only humans in nature, although primates and other animals have been infected in a laboratory setting. Vaccinia, cowpox, and monkeypox viruses can infect both humans and other animals in nature.


Transmission of smallpox occurs through inhalation of airborne variola virus, usually droplets expressed from the oral, nasal, or pharyngeal mucosa of an infected person. It is transmitted from one person to another primarily through prolonged face-to-face contact with an infected person, usually within a distance of 6 feet, but can also be spread through direct contact with infected bodily fluids or contaminated objects (fomites) such as bedding or clothing. Rarely, smallpox has been spread by virus carried in the air in enclosed settings such as buildings, buses, and trains. Smallpox is highly contagious, but generally spreads more slowly and less widely than some other viral diseases, perhaps because transmission requires close contact and occurs after the onset of the rash. The overall rate of infection is also affected by the short duration of the infectious stage. In temperate areas, the number of smallpox infections were highest during the winter and spring. In tropical areas, seasonal variation was less evident and the disease was present throughout the year. ordinary, modified, flat, and hemorrhagic. Historically, variola major has an overall fatality rate of about 30%; however, flat and hemorrhagic smallpox are usually fatal. In addition, a form called variola sine eruptione (smallpox without rash) is seen generally in vaccinated persons. This form is marked by a fever that occurs after the usual incubation period and can be confirmed only by antibody studies or, rarely, by virus isolation. Subclinical (asymptomatic) infections with variola virus have also been noted, but are not believed to be common.
Ordinary smallpox generally produces a discrete rash, in which the pustules stand out on the skin separately. The distribution of the rash is densest on the face; more dense on the extremities than on the trunk; and on the extremities, more dense on the distal parts than on the proximal. The palms of the hands and soles of the feet are involved in the majority of cases. In some cases, the blisters merge together into sheets, forming a confluent rash, which begin to detach the outer layers of skin from the underlying flesh. Patients with confluent smallpox often remain ill even after scabs have formed over all the lesions. In one case series, the case-fatality rate in confluent smallpox was 62%. Flat smallpox is accompanied by a severe prodromal phase that lasts 3–4 days, prolonged high fever, and severe symptoms of toxemia. The rash on the tongue and palate is usually extensive. The skin lesions mature very slowly and by the seventh or eighth day the lesions are flat and appear to be buried in the skin. Unlike ordinary-type smallpox, the vesicles contain very little fluid, are soft and velvety to the touch, and may contain hemorrhages. Flat-type smallpox is nearly always fatal. Strains may be characterized by polymerase chain reaction (PCR) or restriction fragment length polymorphism (RFLP) analysis. Serologic tests and enzyme linked immunosorbent assays (ELISA), which measure variola virus-specific immunoglobulin and antigen have also been developed to assist in the diagnosis of infection.
Chickenpox was commonly confused with smallpox in the immediate post-eradication era. Chickenpox and smallpox can be distinguished by several methods. Unlike smallpox, chickenpox does not usually affect the palms and soles. Additionally, chickenpox pustules are of varying size due to variations in the timing of pustule eruption: smallpox pustules are all very nearly the same size since the viral effect progresses more uniformly. A variety of laboratory methods are available for detecting chickenpox in evaluation of suspected smallpox cases.


The overall case-fatality rate for ordinary-type smallpox is about 30%, but varies by pock distribution: ordinary type-confluent is fatal about 50–75% of the time, ordinary-type semi-confluent about 25–50% of the time, in cases where the rash is discrete the case-fatality rate is less than 10%. The overall fatality rate for children younger than 1 year of age is 40%–50%. Hemorrhagic and flat types have the highest fatality rates. The fatality rate for flat-type is 90% or greater and nearly 100% is observed in cases of hemorrhagic smallpox. The case-fatality rate for variola minor is 1% or less. Other than vaccination, treatment of smallpox is primarily supportive, such as wound care and infection control, fluid therapy, and possible ventilator assistance. Flat and hemorrhagic types of smallpox are treated with the same therapies used to treat shock, such as fluid resuscitation. Patients with semi-confluent and confluent types of may have therapeutic issues similar to patients with extensive skin burns.
No drug is currently approved for the treatment of smallpox. However, antiviral treatments have improved since the last large smallpox epidemics, and studies suggest that the antiviral drug cidofovir might be useful as a therapeutic agent. The drug must be administered intravenously, however, and may cause serious renal toxicity.


The first attempts to prevent smallpox were practiced in India as early as 1000 BC, and involved either nasal insufflation of powdered smallpox scabs, or scratching material from a smallpox lesion into the skin. This procedure was known as variolation and, if successful, produced lasting immunity to smallpox. However, because the person was infected with variola virus, a severe infection could result, and the person could transmit smallpox to others. Variolation had a 0.5–2% mortality rate; considerably less than the 20–30% mortality rate of the disease itself.
An account from letter by Lady Mary Wortley Montagu to Sarah Chiswell, dated 1 April 1717, from the Turkish Embassy describes this treatment:
''.... The small-pox so fatal and so general amongst us is here entirely harmless by the invention of ingrafting (which is the term they give it). There is a set of old women who make it their business to perform the operation. Every autumn in the month of September, when the great heat is abated, people send to one another to know if any of their family has a mind to have the small-pox. They make parties for this purpose, and when they are met (commonly fifteen or sixteen together) the old woman comes with a nutshell full of the matter of the best sort of small-pox and asks what veins you please to have opened. She immediately rips open that you offer to her with a large needle (which gives you no more pain than a common scratch) and puts into the vein as much venom as can lye upon the head of her needle, and after binds up the little wound with a hollow bit of shell, and in this manner opens four or five veins. . . . The children or young patients play together all the rest of the day and are in perfect health till the eighth. Then the fever begins to seize them and they keep their beds two days, very seldom three. They have very rarely above twenty or thirty in their faces, which never mark, and in eight days time they are as well as before the illness. . . . There is no example of any one that has died in it, and you may believe I am very well satisfied of the safety of the experiment since I intend to try it on my dear little son. I am patriot enough to take pains to bring this useful invention into fashion in England, and I should not fail to write to some of our doctors very particularly about it if I knew any one of them that I thought had virtue enough to destroy such a considerable branch of their revenue for the good of mankind, but that distemper is too beneficial to them not to expose to all their resentment the hardy wight that should undertake to put an end to it. Perhaps if I live to return I may, however, have courage to war with them. ...''
In March 1718 she had the embassy surgeon, Charles Maitland, inoculate her five-year-old son. Upon her return to England in 1721, Lady Montegu had her four-year-old daughter inoculated and invited friends to see the child, including Sir Hans Sloane, the King's physician. Despite a great deal of initial prejudice from physicians and the public, this method of controlled infection was used in England, parts of Europe, and the British colonies in the New World during most of the 18th century.
In 1796 Edward Jenner, a doctor in Berkeley, Gloucestershire, rural England, discovered that immunity to smallpox could be produced by inoculating a person with material from a cowpox lesion. Cowpox is a poxvirus in the same family as variola. Jenner called the material used for inoculation vaccine, from the root word vacca, which is Latin for cow. The procedure was much safer than variolation, and did not involve a risk of smallpox transmission. Vaccination to prevent smallpox was soon practiced all over the world. During the 19th century, the cowpox virus used for smallpox vaccination was replaced by vaccinia virus. Vaccinia is in the same family as cowpox and variola but is genetically distinct from both. The origin of vaccinia virus and how it came to be in the vaccine are not known.
There are side effects and risks associated with the smallpox vaccine. In the past, about 1,000 people for every 1 million people vaccinated for the first time experienced serious, but non-life-threatening, reactions including toxic or allergic reaction at the site of the vaccination (erythema multiforme), spread of the vaccinia virus to other parts of the body, and to other individuals. Potentially life-threatening reactions occurred in 14 to 52 people out of every 1 million people vaccinated for the first time. Based on past experience, it is estimated that 1 or 2 people in 1 million who receive the vaccine may die as a result, most often the result of postvaccinial encephalitis or severe necrosis in the area of vaccination (called progressive vaccinia).


Since Jenner demonstrated the effectiveness of cowpox to protect humans from smallpox in 1796, various attempts were made to eliminate smallpox on a regional scale. As early as 1803, the Spanish Crown organized a mission (the Balmis expedition) to transport the vaccine to the Spanish colonies in the Americas and the Philippines, and establish mass vaccination programs there. In 1842, England banned inoculation, later progressing to mandatory vaccination. The British government introduced compulsory smallpox vaccination by an Act of Parliament in 1853. In the United States, from 1843 to 1855 first Massachusetts, and then other states required smallpox vaccination. Although some disliked these measures, In Northern Europe a number of countries had eliminated smallpox by 1900, and by 1914, the incidence in most industrialized countries had decreased to comparatively low levels. Vaccination continued in industrialized countries, until the mid to late 1970s as protection against reintroduction. Australia and New Zealand are two notable exceptions, neither experienced endemic smallpox and never vaccinated widely; relying instead on protection by distance and strict quarantines.
The first hemisphere-wide effort to eradicate smallpox was made in 1950 by the Pan American Health Organization. The campaign was successful in eliminating smallpox from all American countries except Argentina, Brazil, Colombia, and Ecuador. At this point, 2 million people were dying every year. Overall, however, progress towards eradication was disappointing, especially in Africa and in the Indian subcontinent. In 1967, the World Health Organization intensified the global smallpox eradication by contributuing $2.4 million annually to the effort. An international team, the Smallpox Eradication unit, was formed under the leadership of an American, Donald Henderson.
To eradicate smallpox, each outbreak had to be stopped from spreading, by isolation of cases and vaccination of everyone who lived close by. This process is known as "ring vaccination". The key to this strategy was monitoring of cases in a community (known as surveillance) and containment. The initial problem the WHO team faced was inadequate reporting of smallpox cases, as many cases did not come to the attention of the authorities. The fact that humans are the only reservoir for smallpox infection, and that carriers did not exist, played a significant role the eradication of smallpox. The WHO established a network of consultants who assisted countries in setting up surveillance and containment activities. Early on donations of vaccine were provided primarily by the Soviet Union and the United States, but by 1973, more than 80% of all vaccine was produced in developing countries.
By the end of 1975, smallpox persisted only in the Horn of Africa. Conditions were very difficult in Ethiopia and Somalia, where there were few roads. Civil war, famine, and refugees made the task even more difficult. An intensive surveillance and containment and vaccination program was undertaken in the spring and summer of 1977. The last naturally occurring case of indigenous smallpox (Variola minor) was diagnosed in Ali Maow Maalin, a hospital cook in Merka, Somalia, on 26 October 1977.
The global eradication of smallpox was certified, based on intense verification activities in countries, by a commission of eminent scientists on 9 December 1979 and subsequently endorsed by the World Health Assembly on 8 May 1980 as Resolution WHA33.3. The first two sentences of the resolution read: "Having considered the development and results of the global program on smallpox eradication initiated by WHO in 1958 and intensified since 1967 … Declares solemnly that the world and its peoples have won freedom from smallpox, which was a most devastating disease sweeping in epidemic form through many countries since earliest time, leaving death, blindness and disfigurement in its wake and which only a decade ago was rampant in Africa, Asia and South America."


The last cases of smallpox in the world occurred in an outbreak of two cases (one of which was fatal) in Birmingham, England in 1978. A medical photographer, Janet Parker, died from the disease on 11 September 1978, In 2002 the policy of the WHO changed to be against its final destruction. Destroying existing stocks would reduce the risk involved with ongoing smallpox research; the stocks are not needed to respond to a smallpox outbreak. However, the stocks may be useful in developing new vaccines, antiviral drugs, and diagnostic tests.
In March 2004 smallpox scabs were found tucked inside an envelope in a book on Civil War medicine in Santa Fe, New Mexico. The envelope was labeled as containing the scabs and listed the names of the patients they came from. Assuming the contents could be dangerous, the librarian who found them did not open the envelope. The scabs ended up with employees from the CDC who responded quickly once informed of the discovery. The discovery raised concerns that smallpox DNA could be extracted from these and other scabs and used for a biological attack.

Biological warfare

The British may have used smallpox as a biological warfare agent during the French and Indian Wars (1754–63), against France and its Native American allies (see more information at Siege of Fort Pitt). It has been alleged that smallpox was also used as a weapon during the American Revolutionary War (1775–83). During World War II, scientists from the United Kingdom, United States and Japan were involved in research into producing a biological weapon from smallpox. Plans of large scale production were never carried through as they considered that the weapon would not be very effective due to the wide-scale availability of a vaccine.
An outbreak of weaponized smallpox may have occurred during its testing in the 1970s. General Prof. Peter Burgasov, former Chief Sanitary Physician of the Soviet Army, and a senior researcher within the Soviet program of biological weapons described the incident:
“On Vozrozhdeniya Island in the Aral Sea, the strongest recipes of smallpox were tested. Suddenly I was informed that there were mysterious cases of mortalities in Aralsk. A research ship of the Aral fleet came 15 km away from the island (it was forbidden to come any closer than 40 km). The lab technician of this ship took samples of plankton twice a day from the top deck. The smallpox formulation—400 gr. of which was exploded on the island—”got her” and she became infected. After returning home to Aralsk, she infected several people including children. All of them died. I suspected the reason for this and called the Chief of General Staff of Ministry of Defense and requested to forbid the stop of the Alma-AtaMoscow train in Aralsk. As a result, the epidemic around the country was prevented. I called Andropov, who at that time was Chief of KGB, and informed him of the exclusive recipe of smallpox obtained on Vozrazhdenie Island.”
Others contend that the first patient may have contracted the disease while visiting Uyaly or Komsomolsk, two cities where the boat docked.


Eurasian epidemics

It is important to note that, although historical epidemics and pandemics are believed by some historians to have been early outbreaks of smallpox, contemporary records are not detailed enough to make a definite diagnosis at this distance.
The Plague of Athens devastated the city of Athens in 430 BC, killing around a third of the population, according to Thucydides. Historians have long considered this an example of bubonic plague, but more recent examination of the reported symptoms led some scholars to believe the cause may have been measles, smallpox, typhus, or a viral hemorrhagic fever (like Ebola).
The Antonine Plague that swept through the Roman Empire and Italy in 165–180 is also thought to be either smallpox or measles. Smallpox was thus regarded as possession by Sitala. In Hinduism the goddess Sitala both causes and cures high fever, rashes, hot flashes and pustules. All of these are symptoms of smallpox.
Smallpox did not definitively enter Western Europe until about 581 when Bishop Gregory of Tours provided an eyewitness account that describes the characteristic findings of smallpox. Most people became infected during their lifetimes, and about 30% of people infected with smallpox died from the disease.
The Franco-Prussian War triggered a smallpox pandemic of 1870–1875 that claimed 500,000 lives.

Epidemics in the Americas

After first contacts with Europeans and Africans, some believe that the death of 90–95% of the native population of the New World was caused by Old World diseases. It is suspected that smallpox was the chief culprit and responsible for killing nearly all of the native inhabitants of the Americas. For more than 200 years, this disease affected all new world populations, mostly without intentional European transmission, from contact in the early 1500s to until possibly as late as the French and Indian Wars (1754–1767).
In 1519 Hernán Cortés landed on the shores of what is now Mexico and was then the Aztec empire. In 1520 another group of Spanish arrived in Mexico from Hispaniola, bringing with them the smallpox which had already been ravaging that island for two years. When Cortés heard about the other group, he went and defeated them. In this contact, one of Cortés's men contracted the disease. When Cortés returned to Tenochtitlan, he brought the disease with him.
Soon, the Aztecs rose up in rebellion against Cortés and his men. Outnumbered, the Spanish were forced to flee. In the fighting, the Spanish soldier carrying smallpox died. After the battle, the Aztecs contracted the virus from the invaders' bodies. Cortes would not return to the capital until August 1521. In the meantime smallpox devastated the Aztec population. It killed most of the Aztec army and 25% of the overall population. A Spanish priest left this description: "As the Indians did not know the remedy of the disease…they died in heaps, like bedbugs. In many places it happened that everyone in a house died and, as it was impossible to bury the great number of dead, they pulled down the houses over them so that their homes become their tombs." On Cortés's return, he found the Aztec army’s chain of command in ruins. The soldiers who lived were still weak from the disease. Cortés then easily defeated the Aztecs and entered Tenochtitlán. The Spaniards said that they could not walk through the streets without stepping on the bodies of smallpox victims.
The effects of smallpox on Tahuantinsuyu (or the Inca empire) were even more devastating. Beginning in Colombia, smallpox spread rapidly before the Spanish invaders first arrived in the empire. The spread was probably aided by the efficient Inca road system. Within months, the disease had killed the Sapa Inca Huayna Capac, his successor, and most of the other leaders. Two of his surviving sons warred for power and, after a bloody and costly war, Atahualpa become the new Sapa Inca. As Atahualpa was returning to the capital Cuzco, Francisco Pizarro arrived and through a series of deceits captured the young leader and his best general. Within a few years smallpox claimed between 60% and 90% of the Inca population, with other waves of European disease weakening them further. A handful of historians argue that a disease called Bartonellosis may have been responsible for some outbreaks of illness, but this opinion is in the scholarly minority. The effects of smallpox were depicted in the ceramics of the Moche people of ancient Peru.
Even after the two mighty empires of the Americas were defeated by the virus and disease, smallpox continued its march of death. In 1633 in Plymouth, Massachusetts, the Native Americans were struck by the virus. As it had done elsewhere, the virus wiped out entire population groups of Native Americans. It reached Mohawks in 1634, the Lake Ontario in 1636, and the lands of the Iroquois by 1679. During the 1770s, smallpox killed at least 30% of the West Coast Native Americans. Smallpox epidemic of 1780–1782 brought devastation and drastic depopulation among the Plains Indians. By 1832, the federal government of the United States established a smallpox vaccination program for Native Americans.
A particularly virulent sequence of smallpox outbreaks took place in Boston, Massachusetts. From 1636 to 1698, Boston endured six epidemics. In 1721, the most severe epidemic occurred. The entire population fled the city, bringing the virus to the rest of the Thirteen Colonies. In the late 1770s, during the American Revolutionary War, smallpox returned once more and killed an estimated 125,000 people. Peter Kalm in his Travels in North America, described how in that period, the dying Indian villages became overrun with wolves feasting on the corpses and weakened survivors.

Famous sufferers and survivors

Famous historical figures who contracted smallpox include Date Masamune of Japan (who lost an eye to the disease), Ramesses V, the Kangxi Emperor, Shunzhi Emperor and Tongzhi Emperor of China (official history), Maximilian III Joseph, Elector of Bavaria, George Washington, The Incan emperor Huayna Capac in 1527 and Peter II of Russia. Guru Har Krishan 8th Guru of the Sikhs in 1664, Peter III of Russia in 1744. Joseph Stalin, who was badly scarred by the disease early in life, often had photographs retouched to make his pockmarks less apparent.
Families prominent in History the world over often had several people infected by and/or perish from the disease. For example, several relatives of Henry VIII survived the disease but were scarred by it. These include his sister Margaret, Queen of Scotland, his fourth wife, Anne of Cleves, and his daughter, Elizabeth I of England in 1562 (as an adult she would often try to disguise the pockmarks with heavy makeup). A more distant relative, Mary Queen of Scots, contracted the disease as a child but had no visible scarring.
In Europe, deaths from smallpox often impacted dynastic succession. Louis XV of France succeeded his great-grandfather Louis XIV through a series of deaths of smallpox or measles among those earlier in the succession line and he himself died of the disease in 1774. The son of Henry VIII, Edward VI, likely died from complications shortly after apparently recovering from the disease, thereby rendering all of his sire's infamous efforts to provide England with a male heir moot. (His immediate successors were all females.) William III lost his mother to the disease when he was only ten years old in 1660, and named his uncle Charles as legal guardian: her death from smallpox would indirectly spark a chain of events that would eventually lead to the permanent ousting of the Stuart line from the British throne and usher in a new age.
