I never imagined, as I started work on
Pox Americana more than six years ago, that the book's publication would coincide with the appearance of the word "smallpox" in newspaper and television headlines around the world. It was more than unlikely; it seemed downright impossible. Smallpox had been eradicated. It no longer threatened humankind. In May 1980, the 33rd World Health Assembly had triumphantly declared that "the world and all its peoples have won freedom from smallpox."
So confident was this declaration, and so breathtaking were its implications, that I even wrote the following audacious words in an early draft of the book: "In the late twentieth century, smallpox is the only disease known that is appropriately discussed entirely in the past tense."
But what may have been appropriate for the late 20th century is clearly not appropriate for the early 21st. Time passed. Rumors circulated. And the firsthand reports of a former Soviet biological weapons scientist named Ken Alibek jolted us to a new level of alertness. Eradicated for the moment, smallpox was not necessarily eradicated forever. I went back to my manuscript and changed past tense to present. It saddened me to do so.
It saddened me not just because I knew what a momentous effort had gone into smallpox eradication but also because I knew the sorrow and suffering the disease could cause. I knew this firsthand, from my own personal encounter with the historical evidence it left behind.
Pox Americana describes a terrible smallpox epidemic that swept North America from 1775 to 1782. It shows how the disease shaped the early episodes of the Revolutionary War, how it gave the British a biological (and hence military) advantage, and how it dashed the hopes of thousands of freedom-seeking African-American slaves as the war came to an end.
It also shows how this fearsome virus coursed through the Spanish missions of Mexico and traveled northward as far as Canada and southeast Alaska in these same years, wasting native peoples along the way. By the time the Treaty of Paris officially brought the Revolutionary War to a close in 1783, some 25,000 Americans had died in the Continental service. By comparison, some 130,000 Americans had died of smallpox in the same period.
The documentary accounts of the epidemic were grim. "My eyes never before beheld such a seen," wrote a Pennsylvania soldier in awkward but animated prose; "nor do I ever desire to see such another -- the Lice and Maggots seme to vie with each other, were creeping in Millions over the Victims; the Doctors themselves sick or out of Medicine."
A Spanish missionary described the epidemic among the Indians of Baja California just a few years later: "Some threw themselves into the sea, others scorched themselves with firebrands, and the poor little children, abandoned beside the dead, died without help."
And in Canada, an Indian named Saukamappee told a fur trader of the epidemic's aftermath: "When at length it left us, and we moved about to find our people, it was no longer with the song and the dance; but with tears, shrieks, and howlings of despair for those who would never return to us."
What are the lessons for today? Once it gets loose, the smallpox virus depends upon two things for success: vulnerable people and connections between them. In both regards, we are worse off today than we were in the 18th century.
Today, only those few people who are actual survivors of the disease have the acquired immunity that will keep them from catching it. The rest of us are all vulnerable, even if we were vaccinated in childhood.
Moreover, people in the 18th century traveled by foot, horse, sailing vessel, and canoe. Now they travel by airplane and automobile. Thus, on both counts -- vulnerable people and connections between them -- we come up short today.
We do have one advantage that most of our 18th-century forebears did not have. That is vaccination, the seemingly miraculous procedure developed by the English physician Edward Jenner in 1796. By making recipients immune to smallpox, vaccination alters one piece of the equation -- the number of vulnerable people. It is really the only advantage that distinguishes us from our ancestors.
Shouldn't we vaccinate everyone as soon as possible then? That depends. It depends on what the risks are, and it depends on what our public health priorities are.
As of this date, smallpox is still eradicated. The virus has not gotten loose. But other killers -- including cholera, malaria, and HIV/AIDS -- run rampant through the world and threaten the U.S. Despite our newly heightened awareness of biological terrorism, we're still struggling to vaccinate kids against dangerous childhood killers, and we can't even get clean drinking water to millions of people around the globe.
So for now my answer is no, vaccinating everyone is not appropriate. But if the virus gets loose, that may change. As General George Washington put it in 1775 when smallpox threatened his camp, we must "continue the utmost Vigilance against this most dangerous Enemy." Vigilance, not vaccination, should be our priority of the moment. (Elizabeth A. Fenn)

VARIOLA
September 28, 1751. Time has left the early pages of his diary so damaged that the exact date remains uncertain. But it was probably on this day that nineteen-year-old George Washington set sail from Virginia to the island of Barbados with his older half brother, Lawrence. If their departure date is unclear, the brothers' purpose is not: The trip was intended to ease Lawrence's persistent cough and congested lungs, symptoms of the consumption that was to kill him within a year. In the eighteenth and nineteenth centuries, travel abroad was a favored treatment for consumption, the contagious disease that today we call tuberculosis. Early Americans understood consumption to be an ailment of heredity and climate, alleviated by salt air, mountain breezes, or whatever atmospheric conditions best suited a particular patient's constitution. It was the Washingtons' hope that Barbados would suit Lawrence.
The trip was difficult. Hurricanes regularly strafe the Caribbean in the early fall, and 1751 was no exception. The brothers and their shipmates endured a week of stiff gales, rain squalls, and high seas in late October, the effects of a nearby storm. They disembarked at Bridgetown, Barbados, on November 2, 1751. Although the purpose of the journey was to ease Lawrence's consumption, it was soon George who lay seriously ill — not from tuberculosis, but from smallpox.
On November 3, the day after landing, the two brothers begrudgingly accepted an invitation to dine at the home of Gedney Clarke, a prominent merchant, planter, and slave trader with family ties to the Washingtons. "We went, — myself with some reluctance, as the smallpox was in his family," George wrote in his diary. His misgivings were justified. For a fortnight afterward, the two Americans plied the Barbadian social circuit, unaware of the virus silently multiplying in George's body. Then, on November 17, when the incubation period had passed, the infection hit hard. "Was strongly attacked with the small Pox," Washington wrote. Thereafter, his journal entries stop. Not until December 12, when he was well enough to go out once again, did George Washington return to his diary.
The brothers' stay in Barbados was brief. "This climate has not afforded the relief I expected from it," wrote Lawrence. On December 22, the brothers parted ways, George returning to Virginia and Lawrence opting for the more promising climate of Bermuda. Lawrence's health was failing fast. He spent the spring in Bermuda and then hurried desperately to his home at Mount Vernon, Virginia, where tuberculosis took his life on July 26, 1752.
On Sunday, July 2, 1775, a much-older George Washington stepped out of a carriage in Cambridge, Massachusetts, to take command of the Continental army, newly established by the Congress still meeting in Philadelphia. Already, an American siege of nearby Boston was under way. The standoff was the outcome of the battles of Lexington and Concord in April 1775, when an angry throng of New England militiamen had routed a column of British troops attempting to seize a stash of munitions at Concord. Exhausted and humiliated, the king's soldiers had staggered sixteen miles back to Boston under relentless American sniper fire. Here they were trapped. The armed patriots were to besiege them in the city for the next eleven months.
By the time Washington arrived to command the American army in July, the confrontation had taken on an added dimension: It was not just military but medical as well. Smallpox was spreading through Boston. Washington knew how debilitating the disease could be, and he knew that the New Englanders who formed the core of his Boston-based army were among those most likely to be vulnerable. It was a vulnerability they shared with a great many others in late-eighteenth-century North America.
When smallpox struck George Washington in Barbados in 1751, his diary entries stopped for twenty-four days. If this was not inevitable, it was nevertheless predictable. Rare was the diarist who kept writing through the throes of the smallpox. The void in Washington's diary is thus telling; its very silence speaks of a misery commonplace in years gone by but unfamiliar to the world today.
Although the route of infection is impossible to determine, it is most likely that Washington picked up Variola through direct contact with a sick member of the Gedney Clarke household. The contagious party may have been Mrs. Clarke herself, who was "much indisposed" at the time of the brothers' visit. If Washington had a face-to-face meeting with her, he might have inhaled tiny infectious droplets or his hands might have carried the contagion to his mouth or nose. Such an encounter is the most likely mode of infection, but it is by no means the only one possible. Even scabs and dried-out body secretions can transmit smallpox. If someone had recently swept the floors or changed the bedclothes in a sickroom in the Clarke home, desiccated but dangerous particles may have circulated aloft. Finally, one last form of transmission bears mentioning. Variola can survive for weeks outside the human body. Carefully stored, it retains its virulence for years. Thus it is conceivable that George Washington caught smallpox from an inanimate object (often cloth or clothing) contaminated with the virus.
How do we know that Washington caught smallpox in the Clarke household? The acknowledged presence of the disease there is one clue. Timing is another. The incubation period for smallpox usually ranges from ten to fourteen days. A twelve-day incubation is most common, with the first symptoms appearing thirteen days after exposure. George Washington's case was thus fairly typical. He dined at the Clarke home on November 3, and according to his diary, his first symptoms appeared fourteen days later.
We have no firsthand description of Washington's bout with the pox. But to judge by the experience of other victims, his early symptoms would have resembled a very nasty case of the flu. Headache, backache, fever, vomiting, and general malaise all are among the initial signs of infection. The headache can be splitting; the backache, excruciating. Lakota (Sioux) Indian representations of smallpox often use a spiral symbol to illustrate intense pain in the midsection. Anxiety is another symptom. Fretful, overwrought patients often die within days, never even developing the distinctive rash identified with the disease. Twentieth-century studies indicate that such hard-to-diagnose cases are rare. But eyewitness accounts suggest that in historical epidemics, this deadly form of smallpox may have been more common among Native Americans, who frequently died before the telltale skin eruptions appeared.
To judge by the outcome of his illness, George Washington's "pre-eruptive" symptoms were not nearly so grave. The fever usually abates after the first day or two, and many patients rally briefly. Some may be footed into thinking they have indeed had a mere bout of the flu. But the respite is deceptive, for relief is fleeting. By the fourth day of symptoms, the fever creeps upward again, and the first smallpox sores appear in the mouth, throat, and nasal passages. At this point, the patient is contagious. Susceptible individuals risk their lives if they come near.
The rash now moves quickly. Over a twenty-four-hour period, it extends itself from the mucous membranes to the surface of the skin. On some, it turns inward, hemorrhaging subcutaneously. These victims die early, bleeding from the gums, eyes, nose, and other orifices. In most cases, however, the rash turns outward, covering the victim in raised pustules that concentrate in precisely the places where they will cause the most physical pain and psychological anguish: The soles of the feet, the palms of the hands, the face, forearms, neck, and back are focal points of the eruption. Elsewhere, the distribution is lighter.
If the pustules remain discrete — if they do not run together — the prognosis is good. But if they converge upon one another in a single oozing mass, it is not. This is called confluent smallpox, and patients who develop it stand at least a 60 percent chance of dying. For some, as the rash progresses in the mouth and throat, drinking becomes difficult, and dehydration follows. Often, an odor peculiar to smallpox develops. "The small-pox pustules begin to crack run and smell," wrote a Boston physician in 1722. A missionary in Brazil described a "pox so loathsome and evil-smelling that none could stand the great stench" of its victims. Patients at this stage of the disease can be hard to recognize. If damage to the eyes occurs, it begins now. Secondary bacterial infections can also set in, with consequences fully as severe as those of the smallpox.
Scabs start to form after two weeks of suffering, but this does little to end the patient's ordeal. In confluent or semiconfluent cases of the disease, scabbing can encrust most of the body, making any movement excruciating. The Puritan leader William Bradford described this condition among the Narragansett Indians in 1634: "They lye on their hard matts, the poxe breaking and mattering, and runing one into another, their skin cleaving (by reason therof) to the matts they lye on; when they turne them, a whole side will flea of[f] at once." An earlier report from Brazil told of "pox that were so rotten and poisonous that the flesh fell off" the victims "in pieces full of evil-smelling beasties."
Death when it occurs, usually comes after ten to sixteen days of suffering. Thereafter, the risk drops significantly as fever subsides and unsightly scars replace scabs and postules.
