Nothing prevents a state from concealing a weapons program under the guise of protecting commercial secrets

Biohazard by Ken AlibekWe may not realize until too late, Ken Alibek explains (in Biohazard), that we have become the victims of a biological attack:

It is not until days or weeks after such an attack has taken place—after the first wave of deaths—that we will most likely recognize its occurrence.

[…]

A small amount of Marburg or Ebola released in the subway system of Washington, D.C., Boston, or New York, or in an airport, shopping mall, or financial center, could produce hundreds of thousands of victims.

[…]

It is easier to make a biological weapon than to create an effective system of biological defense. Based on our current level of knowledge, at least seventy different types of bacteria, viruses, rickettsiae, and fungi can be weaponized. We can reliably treat no more than 20 to 30 percent of the diseases they cause.

[…]

In a simulated attack staged in New York City in 1998, nearly all of the members of an emergency unit dispatched to the scene “died” because they were insufficiently protected. “They did all the right things,” a federal official who watched the exercise told The New York Times. “But the scenario utterly defeated them.” The emergency teams were hampered by their inability to identify which biological agents had been used.

[…]

Most methods involve the exposure of vials or petri dishes containing laboratory-grown cultures to air samples from a suspected target area. This can be a laborious process. A field monitoring device used during the Gulf War took between thirteen and twenty-four hours to make a positive identification. For botulinum toxin, one of the staples of Iraq’s arsenal, this would already be too late.

Technology has improved since then. The Biological Integrated Detection System (BIDS) cut the time to only thirty minutes, but it can so far only determine the presence of anthrax, plague, botulinum toxin, and staphylococcus enterotoxin B.

In September 1998, he explains, Clinton and Yeltsin agreed in Moscow on a program of “accelerated negotiations” to strengthen the Biological Weapons Convention:

In America, the loudest protests have come from commercial biotechnology companies, who argue that open-ended inspections of their labs and production facilities will leave them vulnerable to industrial espionage. Biotechnology is a multi-million-dollar industry. Between 1989 and 1996 the number of firms in the United States developing new-generation drugs soared from 45 to 113.

[…]

Nothing prevents a state from concealing a weapons program under the guise of protecting commercial secrets.

Arms treaties are important. They set standards of international behavior regarding the acquisition and use of weapons of mass destruction. But they are almost invariably ignored when countries believe their national security is at stake.

The American plan to stockpile and develop vaccines against known agents is the most comprehensive of its kind in the world, Alibek notes, but, as parts of that plan have been implemented, its limitations have become clear:

Mandatory immunization of troops has been official Pentagon policy since 1993. All 2.3 million American soldiers have begun to receive shots against anthrax, currently regarded as the principal threat because of its documented presence in Saddam Hussein’s arsenal. But no vaccines are contemplated against other agents believed to be in that arsenal, such as aflatoxin, botulinum, and smallpox. The extra cost would be enormous (the six-year anthrax vaccine program alone will cost the military an estimated $ 130 million) and vaccines are not without side effects. Injecting soldiers against dozens of diseases would not protect them from the agents we don’t know about, or from those for which there are no known vaccines.

[…]

Vaccines made of live but weakened microorganisms are generally more effective than those made of nonliving cellular or subcellular components. Both types are usually benign, but in rare cases they can trigger significant changes in the blood and endocrine systems. Some have been known to affect the functioning of the heart, lungs, kidneys, and other organs. It is not medically advisable to combine too many different courses of vaccination.

There are currently no known vaccines for brucellosis, glanders, and melioidosis or for many viral diseases, such as Ebola and Marburg. The plague vaccine was found to be ineffective against aerosol dissemination in animal studies. The tularemia vaccine is difficult to culture and potentially dangerous. Of the four possible strains available for viral encephalitis, the first and most potent (a live vaccine) produces adverse reactions in 20 percent of all cases and is ineffective in 20 percent. The second is of restricted effectiveness (it only works against three subtypes of the disease), and the third and fourth are poorly immunogenic and require multiple immunizations. The smallpox vaccine, only available in the United States to lab workers and military personnel, can be administered either before or after infection. It requires periodic boosters and wears out after ten years, though revaccination is required after three years in case of infection. Skin testing is recommended for Q fever and botulinum toxin.

The anthrax vaccine used in the United States has to be administered six times before it becomes effective (three times in two-week intervals and three times in six-month intervals) with annual boosters thereafter.

[…]

American experts maintain that annual boosters are safe—the live vaccine we used in Russia was associated with some risks—but scientists generally agree that excessive vaccination can create complications in the immune system, leading in rare cases to the formation of tumors.

Repeated vaccinations has been known to trigger or aggravate allergies. Thirty minutes after I received my last vaccination against anthrax in 1987, my face became swollen, and I developed a rash and had trouble breathing. I took Dimidrol, a powerful anti-allergy medication available in Russia (though not in the United States) and felt better again in a few hours. For the next ten days I received intravenous preparations at a hospital—a form of allergy treatment we called desensibilization therapy. Several colleagues had been forbidden from anthrax work after similar reactions.

[…]

I received my first anthrax vaccination in 1979 and began a course of annual vaccinations in 1982. I was also vaccinated against smallpox once, twice against tularemia, and four times against plague. The chronic allergies I have suffered throughout my adult life are a direct consequence of repeated exposure to live vaccines, and to other biological substances I worked with.

Vaccines provide excellent protection against specific diseases, but the characteristic that makes them so effective—that specificity—is also the source of their limitations.

[…]

Despite American efforts and expenditures, vaccines have limited value for the protection of civilians.

Fears that the Germans would use biological munitions in their unmanned “buzz bomb” never materialized

Friday, September 18th, 2026

Biohazard by Ken AlibekGreat Britain and Canada began investigating biological agents and delivery systems in 1940, Ken Alibek explains (in Biohazard), but President Franklin D. Roosevelt didn’t establish a program until fifteen months after the United States entered World War II, in March 1943:

Based on what Patrick told me of the early history of their program, Americans knew nothing of the ambitious weapons-making drive we [the USSR] had launched in the 1920s.

[…]

The Americans were not fully persuaded until their British and Canadian allies noted that the Germans were suspected of having used glanders against Romanian cavalry during World War I and seemed to be amassing a larger bacteriological arsenal. The Canadians had converted an agricultural experiment station in Suffield, Alberta, into a testing area for anthrax. In southern England, an old chemical warfare proving ground at Porton Down was adapted for the same purpose.

In America, a secret biological warfare unit called the War Research Service was created to work with its British and Canadian counterparts. George W. Merck, president of Merck & Co. Inc., a leading U.S. pharmaceutical firm, was the unit’s first director.

[…]

They settled on four principal sites: a 2,000-acre tract on Horn Island near Pascagoula, Mississippi; the Dugway chemical warfare testing facility in the Utah desert; a 6,100-acre munitions manufacturing complex at Terre Haute, Indiana; and the old National Guard installation at Frederick, Maryland.

[…]

More than seventeen hundred people worked at Camp Detrick during the war years, investigating glanders, brucellosis, cholera, dysentery, plague, and typhus.

Anthrax was the largest project. Scientists built a pilot plant capable of producing anthrax in ten-thousand-gallon tanks. They were so successful that Britain placed an order for five hundred thousand anthrax bombs from the facility in September 1944.

[…]

Fears that the Germans would use biological munitions in their unmanned “buzz bomb” raids over English cities, or to repel the D-Day force, never materialized.

[…]

Some facilities were phased out, but revelations about Japan’s Unit 731 forestalled any serious discussion about ending the American program.

[…]

Camp Detrick sent scientists to Japan to interrogate the commanders of Unit 731, who gave details of their program in return for avoiding prosecution for war crimes. Their reports convinced Washington that biological weapons could be developed in greater quantities and with far greater effectiveness than anyone had suspected. The British came to a similar conclusion and decided to upgrade their testing and research unit at Porton Down and at a test site on the Scottish island of Gruinard.

[…]

Beginning in 1951, agricultural agents were developed at Camp Detrick and other facilities to attack the Soviet wheat crop and the rice paddies of Communist China. The pathogens were stored at Edgewood Arsenal in Maryland, as well as at Rocky Mountain Arsenal near Denver, which also manufactured plutonium for nuclear weapons.

U.S. bioweaponeers went on to explore antipersonnel agents such as tularemia, Venezuelan equine encephalitis, and staphylococcal enterotoxin B. Aerosols were tested on animals at Deseret Island in the Pacific Ocean and at Dugway Proving Ground in Utah. They conducted experiments with simulated weapons, as we did, in urban areas.

Human tests took place in 1955 on a group of young Seventh Day Adventists who volunteered as an alternative to military service. The volunteers were exposed to Q fever, which is not lethal and can be treated with antibiotics, in a program called Project Whitecoat, or Operation CD-22.

By the late 1960s, twenty-two microorganisms were under study, and there were plans to weaponize hemorrhagic fevers such as the Machupo virus and Rift Valley fever.

[…]

Nixon, convinced by his advisers that biological warfare was impractical, signed an executive order on November 25, 1969, renouncing the use of lethal biological agents and weapons and promising to confine American biological research to “defensive measures” such as immunization and bio-safety.

We didn’t believe a word of Nixon’s announcement. Even though the massive U.S. biological munitions stockpile was ordered to be destroyed, and some twenty-two hundred researchers and technicians lost their jobs, we thought the Americans were only wrapping a thicker cloak around their activities.

Nixon turned most of Camp Detrick’s buildings over to the National Cancer Institute and assigned to the complex the task of finding a cure for cancer.

The same agents, even the same types of aerosols, were used in experiments occurring sometimes less than a year apart

Wednesday, September 16th, 2026

Biohazard by Ken AlibekWhen Ken Alibek collaborated on a secret history of the Soviet and American programs after his defection, as he explains in Biohazard, he was amazed to discover how closely the research efforts of both countries dovetailed between 1945 and 1969:

The same agents, even the same types of aerosols, were used in experiments occurring sometimes less than a year apart.

[…]

The uncanny similarity between our programs may have been more than a coincidence. Pavel Sudoplatov, a former general of the NKVD (the precursor of the KGB), provided an unwitting clue in his memoirs, published in 1996. Sudoplatov reported almost offhandedly that classified U.S. material on bacteriological weapons research had been transmitted on a regular basis to Moscow during the 1940s and 1950s.

[…]

There had to be at least one informer, if not several, in the American program.

The 1972 Biological Weapons Convention had no provisions for inspections

Monday, September 14th, 2026

Biohazard by Ken AlibekIn October 1990, Ken Alibek explains (in Biohazard), they were informed that a “trilateral agreement” had been reached between the Soviet Union, the United States, and Great Britain to organize a series of reciprocal visits to suspected biological warfare facilities:

The 1972 Biological Weapons Convention had no provisions for inspections, a limitation that continues to frustrate the international arms control community to this day. Visits were to depend on the trust and goodwill of all sides.

[…]

The memo from the Ministry of Foreign Affairs notifying us of the agreement had left it to us to decide which facilities to open. The defense ministry quickly signaled it wanted no part in this charade. You can show whatever you want in Biopreparat,” General Yevstigneyev snapped when I asked for his suggestions. “But no foreigner is getting into our military sites.”

Kalinin, sensing a political opportunity, volunteered that Biopreparat act as the host. He ordered me to decide which of our installations could be “sacrificed” in the interests of East-West relations.

The choices were grim. Though some of our explosive test chambers had been dismantled since Gorbachev’s decree, large industrial fermenters at Stepnogorsk and Omutninsk furnished unmistakable evidence of our activities.

At the time, Biopreparat controlled about forty facilities in fifteen cities across the Soviet Union. About a dozen were used exclusively for offensive work, but many others mixed civilian and military functions. Judicious exposure of the Western delegation to these dual-function facilities would protect us while demonstrating our good faith.

[…]

I never believed that we would be able to pull it off. Anyone with basic knowledge of biological weapons would recognize the signs of our activity.

[…]

The strategy, carefully worked out over the previous weeks, was to waste as much time as possible during the nonessential parts of the tour, to reduce the “official” segments in which our visitors could exercise their curiosity. We had also notified our institute directors in advance to stock up on supplies of vodka and cognac, in the hope of befuddling them with Russian hospitality.

[…]

Obolensk, our next destination, was more difficult. It would require finesse to explain the heavily insulated buildings and labs, the animal cages in our bacteriological genetic engineering program, and other elements of a biowarfare infrastructure. It would be hard, I thought, to conceal our projects to develop antibiotic-resistant strains of tularemia, plague, brucellosis, glanders, melioidosis, and anthrax and to pass our work off as biodefense.

[…]

“Could we finally get to work?” Davis said as Urakov paused for breath during an extended welcoming speech.

The general was undaunted. He told the foreigners that they were free to see whatever they wanted in his compound.

“However, I must warn you that biodefense work involves very hazardous organisms as I’m sure you know,” he said. “If you elect to go into some of our labs, we may have to ask you to stay in quarantine for a couple of weeks. Those are our regulations.”

This was partly true. We did have regulations requiring visitors to stay under observation, but they were totally unnecessary in this case: I had given orders that weekend for Obolensk and Vector to be totally disinfected. The delegation could have walked through any one of the labs in shirtsleeves.

Our visitors, naturally, were unaware of this. They hesitated.

“So,” said Urakov brightly. “What would you like to see?”

They asked for a complete tour of the complex. We got our first rude surprise when Davis pulled out a map and pointed to a large building.

“Take us there,” he said, pointing to the structure that contained Obolensk’s newest, and biggest, explosive chamber.

Ah, I said to myself, here it comes. I assumed the map was based on satellite reconnaissance photos. Pasechnik couldn’t have known about this.

[…]

The visitors were allowed to wander in the corridors until they came to a closed door.

“What’s in here?” Davis asked. No one answered. “Could you please open it?”

“We lost the key,” Petukhov mumbled. “I’ll see if I can find a copy.”

While the visitors waited impatiently, Petukhov took his time finding a “new” key. He eventually opened the door, but the room was dark.

“Can you turn the light on?” Davis asked in irritation.

“Not possible,” Petukhov said. “The bulb is out.”

Undeterred, Davis walked right past him and pulled out a flashlight. At that moment, the façade of international cooperation ended.

Petukhov lunged for the flashlight. Davis shouted. The two men tussled back and forth until someone suggested that they take the dispute back to the conference room, where I was awaiting their return.

[…]

When Davis finally went back and turned the flashlight on, he saw that the walls near the door were dented and pitted—the telltale marks left by fragments of explosives.

“You have been using explosives here,” he declared.

Then, in Novosibirsk:

I could see their eyes widen with astonishment as we took them past enormous steel fermenters, larger than what any Western pharmaceutical firm would ever use for the mass-production of vaccines. We had taken them to one of Vector’s principal research labs—but we made sure to keep them on the ground floor.

In the upper levels were floors dedicated to work on smallpox, Ebola, Machupo, Marburg, Junin, and other hemorrhagic fevers, as well as VEE, Russian spring and summer encephalitis, and a number of other deadly viruses.

[…]

They asked whether they could take air samples and smears from some of the lab areas.

“We haven’t tried to hide the fact that we work with dangerous strains—for defensive purposes,” I replied. “But I don’t have any instructions about allowing you to take samples outside the country. We don’t want to be responsible for a terrible accident.”

Neither did they.

“I can always ask for permission,” I added helpfully. “It might take time and you’d have to wait here for an answer, but I’m sure you’ll be well treated.”

They didn’t press further.

Sandakchiev and I noted with relief that they had not brought special equipment. We had feared for months that the visitors would be carrying advanced monitors capable of detecting viral DNA. Such monitors would have picked up irrefutable evidence of smallpox, and we would have a lot of explaining to do.

The poverty of the lab seemed grimmer by comparison

Biohazard by Ken AlibekIt was impossible to believe, Ken Alibek explains (in Biohazard) that their most important military rival, the U.S., wasn’t pursuing an active biological warfare program:

As part of my duties at Biopreparat I reviewed our budget regularly with Gosplan, the state economic planning agency. Every time I visited the block-long building on Gorky Street, the resources available to us seemed to increase. General Roman Volkov, the balding, scholarly official in charge of funding Ministry of Defense programs, practically begged me to look for ways to spend money.

“I’ve got three hundred million rubles for you in this year’s budget,” he told me in 1990. “You still haven’t supplied me with programs on which to spend them.”

When I suggested civilian medical projects, he brushed me off irritably.

“If you give me more suggestions like that, you’ll never get any money,” he said.

This made little sense to me. Our health-care system was getting worse every day, and conditions in our hospitals were abysmal. The previous year, Biopreparat had shipped boxes of disposable plastic syringes to medical facilities around the country in response to an AIDS scandal in Elista, a small city on the northern steppes of the Caspian Sea. Two hundred and fifty children at the city’s main pediatric hospital had been diagnosed with HIV after having been infected by contaminated syringes. Nurses complained that shortages of equipment and staff prevented them from employing adequate sterilization methods. Stories like these were rife throughout the country.

In February 1990, Valery Ganzenko, the head of the medical directorate, came to my office with a bagful of dirty vaccine vials.

“These are being produced at our facility in Georgia,” he complained. “Hospitals in the area are sending them back to us because they’re not sterile. When I ask the Georgians what’s going on they can’t explain it, but we just sent them a big grant to upgrade their equipment.”

I was responsible for the civilian institutes operating within Biopreparat as well as for our military research program. The supervision of vaccine production and antibiotic development for our state health system occupied almost 50 percent of our official functions. Kalinin paid almost no attention to this part of our agency, and neither did others in the senior staff. We gave civilian managers free rein, and inevitably much of our equipment ended up on the black market. No one seemed to care. But I found myself increasingly drawn to our medical programs and allocated time to them whenever I could.

“Maybe we should take a special trip down to Tbilisi,” I suggested to Ganzenko. He was pleasantly surprised.

“I didn’t think anyone around here wanted to spend time on this kind of thing,” he said.

So he goes to visit the lab:

“Why don’t we go to your lab?” I said.

“Later,” he said. “You must first enjoy Georgian hospitality.”

On our first night he took us to a restaurant where he’d reserved a private room. The table was laden with meat, cheese, fish, and bottles of wine—all in short supply at ordinary food stores in Moscow.

The poverty of the lab we visited the following morning seemed grimmer by comparison. Some of the equipment was over forty years old. Workers used tiny ovens to culture vaccines. Our host was unapologetic, insisting that Biopreparat’s funds were being spent on wages and operating costs.

I knew he was lying as soon as I began talking to the staff. Most of the three hundred employees were women. They told me they were earning such pitiful salaries that they couldn’t even afford lunch.

On some sort of island, a big island, very close to the sea

Wednesday, September 9th, 2026

Biohazard by Ken AlibekKen Alibek explains (in Biohazard) what happened when a Soviet bio-weapons researcher did not return from a trip abroad:

“Who gave him permission to go?”

“I did,” I said. “But I told you about it.”

Shortly after Pasechnik’s initial request, I had informed Kalinin of the invitation from the French company. I had full authority to grant permission for such trips, but Kalinin had told me to keep him abreast of staff movements.

“I don’t remember that,” Kalinin shot back, glancing at Bykov. “You didn’t tell me a thing!”

I felt an involuntary shudder. Kalinin was making it perfectly clear that I was on my own. He looked uncomfortable nonetheless.

Bykov seemed suddenly to enjoy the awkward position in which his rival had been placed. A veteran of Kremlin power struggles, he knew how to take advantage of such situations.

Skipping ahead:

“Well, we think we know where he is.”

“How did you find him?”

“We used a psychic,” Yermoshin explained.

“We showed him a photo of Pasechnik, and he stared at it for a long time until he told us that your man was on some sort of island, a big island, very close to the sea.”

“An island?” I said, puzzled.

“Yes of course,” Yermoshin went on.

“And he said there was a large old building, with two or three men working with him.”

I started to smile. I had never dreamed the KGB was interested in extrasensory perception.

Skipping way, way ahead:

In January 1995, long after I had defected, I was invited by the British government to discuss biodefense issues. During a break, several British officers came up to me and we began to talk through an interpreter about Pasechnik, whom I had not seen since 1989. The mood was light, and I casually told them the story of the KGB and its psychic. They didn’t laugh.

“But that’s exactly where we had him,” one of the officers said. “We wanted to keep him secure, so we brought him to an old house on the coast.”

The KGB psychic was either remarkably talented or he had remarkably good contacts. Even at the time, I suspected that Yermoshin had been ordered to let me in on the psychic’s “secret” to check my reaction. Bykov or Kalinin must have been determined to catch me up. If I had not shown surprise at the news about the island, it would have been proof of guilt. I was angry with Yermoshin for agreeing to be part of such a clumsy trick.

Their reaction:

A consensus was reached quickly. Everything relating to secret defense work at Pasechnik’s facility would have to be destroyed. The Institute of Ultra-Pure Biopreparations would become civilian in fact as well as in name. This would leave a major hole in our program, but there was no alternative.

[…]

“There’s only one thing to do. He has to be killed.”

[…]

One of the KGB colonels spoke up. “I’d like to stop this discussion,” he said softly.

“Nobody is going to say anything about killing here.”

A chill came over the room. I think we all got the message: if an assassination was required, the KGB needed no advice from amateurs.

The key was clearly its general-purpose, algorithmic nature

Tuesday, September 8th, 2026

Many seemingly basic questions of area, length and tangents could not be solved by the ancient geometers:

Even when solutions could be found, they were always ad hoc. As with the circle, Archimedes was also able to find the area enclosed by a line and a parabola. But his solution required an ingenious setup that was entirely different from his solution for the circle. Every property of every curve needed its own distinct solution.

This was the problem that 17th century mathematicians were aiming to address. Before calculus had been invented, René Descartes described in a 1619 letter his ambitious goal to create an “entirely new science, by which all problems that can be posed, concerning any kind of quantity, continuous or discrete, can be generally solved.”

Newton’s mentor Isaac Barrow demonstrated the fundamental theorem of calculus and came close to developing a true general calculus. In describing his unified approach to analyzing curves, he wrote: “I have previously proved a number of general properties of curves of continuous curvature, deducing them from a certain mode of construction common to all.”1

The first publication on (differential) calculus proper is credited to Gottfried Leibniz in 1684; it is from here the name “calculus” originates. To understand how Leibniz perceived his invention and its importance, we need only read the title of the paper: “A new method for maxima and minima, and for tangents, that is not hindered by fractional or irrational quantities, and a singular kind of calculus for the above mentioned.” In other words, it was one method (“singular kind of calculus”) from which multiple properties (maxima, minima, and tangents) could be obtained, applicable even to complicated curves (“not hindered by…”).

The key was clearly its general-purpose, algorithmic nature. Leibniz gave for the first time the world a tool that made the calculation of these properties easy, systematic and general. In the paper he provided not only algorithms for determining tangents, minima and maxima for general curves, but also a corresponding notation and general rules of differentiation (e.g., the addition rule, product rule, quotient rule and power rule). A few years later, Leibniz also published papers on integral calculus and on the fundamental theorem of calculus.

Independently and before Leibniz, Newton also invented a calculus he called the Method of Fluxions, though it remained unpublished until after his death. The two methods differed in important ways—certainly in terminology and symbols used—and yet generality was also key to the Method of Fluxions.

One of Pasechnik’s most important projects was the modification of cruise missiles for the delivery of biological agents

Monday, September 7th, 2026

Biohazard by Ken AlibekThe Institute of Ultra-Pure Biopreparations, Ken Alibek explains (in Biohazard), provided many of the Soviet Union’s breakthroughs in bio-weapons production:

One of its most notable contributions was a milling machine that used a powerful blast of air to turn bacterial and viral mixtures into a fine powder. Nothing like this “jet-stream” machine had ever been built before, at least so far as we knew. It was intended to replace the heavy ball-bearing mills used for decades by the Ministry of Defense and to become a standard fixture at all of our production plants.

Work was also done on new approaches to drying and microencapsulation—the process of covering agents in polymer capsules to preserve and protect them from ultraviolet light. Highly pathogenic agents were forbidden inside the city limits, so the focus of the institute was on developing new processes and equipment.

One of Pasechnik’s most important projects was the modification of cruise missiles for the delivery of biological agents. The Leningrad scientists were asked to analyze the efficiency of aerosol clouds sprayed from a “fast-flying, low-altitude moving object” containing one or more twenty-liter canisters of liquid or dry agent. They designed a moving platform to release canisters as the missile passed over successive targets. The canisters would break apart on impact with the air.

The mysterious virus appeared to liquefy body organs

Saturday, September 5th, 2026

Biohazard by Ken AlibekThe first recorded outbreak of the virus we now call the Marburg virus occurred in 1967, Ken Alibek explains (in Biohazard), at the Behring pharmaceutical works in Marburg, an old university town seventy miles north of Frankfurt:

An animal keeper died two weeks after he contracted a mysterious illness from green monkeys sent to the Behring lab from central Africa. The lab was culturing vaccines in kidney cells extracted from the monkeys. Other workers soon fell sick, and similar cases were reported at laboratories in Frankfurt and Belgrade, both of which had received shiploads of green monkeys from central Africa at the same time.

Twenty-four lab technicians came down with the unknown disease, along with six of the nurses caring for them. Of the thirty-one people infected, seven died. This kind of undiagnosed outbreak would be alarming enough, but it was the horror of their deaths that caught the attention of biologists and tropical disease specialists around the world.

The mysterious virus appeared to liquefy body organs. One of the survivors went mad after the organism chewed away his brain cells. Before the victims died, every inch of their bodies was wet with blood.

Following tradition, the virus was named after the place where it was first identified. It would alter forever the image of a city that has been a center of European philosophy, science, and religion for centuries.

Some of the world’s greatest bacteriologists and biochemists have studied at Marburg—including Albrecht Kossel, whose research laid the groundwork for the discovery of DNA, and Alexandre Yersin, a codiscoverer of the plague bacterium (named Yersinia pestis after him). The lab in which Marburg was first smeared on a glass slide was itself named after the man credited with founding the science of immunology—Emil von Behring.

A similar virus surfaced nine years later on the banks of the Ebola River in Zaire, now the Democratic Republic of Congo. By the time that epidemic died out, 430 people were dead in Zaire and nearby Sudan.

[…]

Under an electron microscope, both organisms seemed to proliferate by shooting out tiny filament-like threads, like the lines cast by fishermen, from the cells they had already scoured for the food they needed to grow. The threads were often bent at the top, like fishing hooks, and as they prepared to invade a new cell they curled into rings, like microscopic Cheerios. Marburg and Ebola were deemed to belong to a new family of viral organisms. They were called filoviruses.

[…]

Ebola’s mortality rate is between 70 and 90 percent.

Naturally the Soviets developed weaponized versions:

A strain of Marburg arrived in the Soviet Union a decade after it was first isolated, during one of our periodic global searches for promising material. It wasn’t clear from the records whether we obtained it from the United States or directly from Germany, but it was immediately added to our growing collection of viral warfare agents. We were already investigating a number of microorganisms that weaken blood vessels and cause hemorrhagic fevers, such as Junin from Argentina and Machupo from Bolivia.

And, naturally, accidents occurred:

Ustinov had been conducting a series of experiments with guinea pigs and rabbits to monitor the effects of increasingly higher concentrations of Marburg. The injection of such a highly concentrated dose directly into his thumb meant that he now had hundreds, perhaps thousands of times more particles of the virus coursing through his body than any of the victims in Germany. I thought his chances of survival were near zero.

[…]

This was less than two years after Chernobyl; the Soviet Union was in no mood for a new disaster.

[…]

No technician should have worked long hours with such a contagious organism. People tired easily in the heavy protective suits required for Zone Three. Their reflexes slowed down, and it was easy to become careless. Adding to our problems, Marburg research had begun at Vector before a supply of antiserum was on hand.

Ustinov’s illness lasted nearly three weeks. Throughout that time, none of his colleagues was allowed to stop working.

[…]

Ustinov had been injecting Marburg into guinea pigs with the help of a lab technician, working through a glove box. He was not in a full space suit and was wearing two thin layers of rubber gloves instead of the thick mitts normally required for such work in Zone Three. The gloves provided the flexibility to control the laboratory animals, who will otherwise squirm and try to wriggle out of a technician’s grip.

Our rules required that animals targeted for injection be strapped to a wooden board to hold them securely in place. That day, Ustinov wasn’t following procedure. He decided to steady the guinea pigs with his gloved hand. Perhaps he thought it would help calm them. Or perhaps he was in too much of a hurry.

The technician became distracted and nudged him accidentally. Ustinov’s hand slipped just as he was pressing down on the syringe. The needle went through the guinea pig and punctured his thumb, drawing blood.

The needle went in no farther than half a centimeter, but the faint spot of blood indicated that liquid Marburg had entered his bloodstream. As soon as he realized what had happened, Ustinov called the duty supervisor from the telephone inside the lab.

From then on, the procedures established for such emergencies were followed to the letter. Doctors and nurses dressed in protective suits were waiting for him as he emerged from the disinfectant shower. They rushed him to the small hospital in the Vector compound, a twenty-bed isolation facility sealed off from the outside with thick walls and pressure-locked doors.

[…]

Within a couple of days he was complaining of a severe headache and nausea. Gradually, he became passive and uncommunicative, as his features froze in toxic shock. On the fourth day his eyes turned red and tiny bruises appeared all over his body: capillaries close to his skin had begun to hemorrhage.

Ustinov twitched silently in his bed while the virus multiplied in his system. Too tired to speak, or to turn over, or to eat, he would drift in and out of consciousness, staring for long periods of time at nothing. Occasionally, lucidity would return. He called for paper during those brief moments to record the progress of the virus as it foraged through his body. Sometimes he burst into tears.

On the tenth day, his fever subsided and he stopped retching. As brilliant a scientist as he was, Ustinov began to entertain the delusion that he was improving. He started smiling again and asked about his family.

[…]

By the fifteenth day, the tiny bruises on Ustinov’s body had turned dark blue, and his skin was as thin as parchment. The blood pooling underneath began oozing through. It streamed from his nose, mouth, and genitals. Through a mechanism that is still poorly understood, the virus prevents normal coagulation: the platelets responsible for clotting blood are destroyed. As the virus spreads, the body’s internal organs literally begin to melt away.

Shuddering bouts of diarrhea left rivers of black liquid on his sheets. The scraps of paper on which he had been scribbling his symptoms and which the nurses had gingerly carried out to transcribe each day no longer littered the floor. There was nothing more to write.

[…]

Each viral particle, or virion, forms a brick that pushes against the cell walls until they burst. The cells then sprout wavering hair-like antennae that home in on their next target, where the process of foraging and destruction blindly repeats itself.

[…]

The doctors from the Ministry of Health arrived early in the first week with the antiserum. To no one’s surprise, it proved useless. Antiviral drugs such as ribavirin and interferon were also tried. Hemorrhagic fevers can sometimes be treated with whole-body blood transfusions, but the medical team concluded that it would in this case be ineffective.

[…]

I don’t know how the senior levels of our bureaucracy reacted to Ustinov’s death, but no condolence letter was ever sent to his widow. Sandakchiev asked us for ten thousand rubles as special compensation for his family in addition to the normal pension survivors were entitled to. It was a princely sum in those days, and Kalinin balked at first, but he finally approved the request.

[…]

The risk of contagion made normal interment impossible, so his corpse was covered with chloramine disinfectant and wrapped in plastic sheeting. The remains were placed inside a metal box, welded shut, and fitted into a wooden coffin. Only then was it safe to lay him in the ground.

[…]

The small group of mourners included Ustinov’s immediate family, his closest colleagues, and a cordon of KGB agents who had worked frantically to keep the circumstances of his illness secret. No one came from Moscow.

Regulations prohibited the circulation of any reports about accidents, fatal or otherwise, but news of the tragedy spread quickly through The System.

[…]

A virus grown in laboratory conditions is liable to become more virulent when it passes through the live incubator of a human or an animal body. Few were surprised, therefore, when samples of Marburg taken from Ustinov’s organs after his autopsy differed slightly from the original strain. Further testing showed that the new variation was much more powerful and stable.

No one needed to debate the next step. Orders went out immediately to replace the old strain with the new, which was called, in a move that the wry Ustinov might have appreciated, “Variant U.”

[…]

After testing the weapon in explosive chambers, we applied it to the monkeys. Every one of the twelve monkeys contracted the virus. They were all dead within three weeks.

In early 1990, Marburg Variant U was ready for approval by the Ministry of Defense.

Our scientist had found it more difficult to cultivate Ebola than Marburg—they were not able to reach the necessary concentration—but by the end of 1990, the long-term problem of cultivation had been solved and we were close to developing a new Ebola weapon. Meanwhile, at Zagorsk (Sergiyev Posad) military scientists were putting the finishing touches on new Lassa fever and monkey pox biological weapons.

Biohazard by Ken AlibekOf all the diseases that have tormented mankind, Ken Alibek explains (in Biohazard), smallpox has left the oldest and the deepest scars:

Recorded as early as 1122 B.C. in China, it altered the course of history, ravaging eighteenth-century Europe and decimating the native populations of North America. Smallpox comes from the pox family of viruses, which assault the upper respiratory tract. Variola major, the scientific name by which the smallpox virus is known, is patient and systematic. It will begin by insinuating itself into cells close to the surface of the skin and in the neural system. The smallpox virus sheds its shell as soon as it enters a live cell, and quickly begins to multiply. Viral transcription begins almost immediately, inhibiting DNA synthesis and thereby preventing the cell from activating its defense mechanisms. Once the virus has inserted its genetic information into the host cell, proteins and enzymes are created to help it mature and develop. The progress of the virus can be mapped by the spread of tiny pink spots from the face and arms to the lower regions of the body.

Smallpox symptoms were once familiar to every doctor. After a quiet incubation period of five to ten days, the virus manifests itself suddenly. The first stage of the disease brings high fever, vomiting, headache, and a strange stiffness. This can last from two to four days. Within less than a week, small spots will begin to develop, forming a rash around the face. As the rash spreads over the following week these spots will develop into painful blisters. In the normal course of the illness, the blisters form scabs that linger for several weeks until they dry and fall off, leaving scars. More severe forms of black or red pox can lead to death within three to four days.

[…]

On May 8, 1980, the World Health Organization announced that smallpox had been eradicated from the planet. The last naturally occurring case was reported in Somalia in 1977, and no new cases had been detected in three years. The WHO recommended the discontinuation of smallpox immunization programs, observing that there was no longer any need to subject people to even the negligible risk connected with vaccination.

The international agency simultaneously adopted a resolution restricting the world’s stocks of smallpox to four sites, where limited quantities would be available for research purposes. A few years later, the sites were narrowed down to two: the Centers for Disease Control in Atlanta and the Ivanovsky Institute of Virology in Moscow.

The conquest of smallpox generated a special feeling of accomplishment in the Soviet Union: the worldwide crusade against smallpox had been a Soviet initiative. Moscow first proposed the campaign at a World Health Organization meeting in 1958, and its sponsorship of vaccination programs in the third world won it admirers everywhere. Russia had suffered its share of smallpox outbreaks over the centuries, finally managing to eliminate the disease in 1936, after a decade-long immunization program sponsored by the fledgling Bolshevik government.

Soon after the WHO announcement, smallpox was included in a list of viral and bacterial weapons targeted for improvement in the 1981–85 Five-Year-Plan.

Where other governments saw a medical victory, the Kremlin perceived a military opportunity. A world no longer protected from smallpox was a world newly vulnerable to the disease.

[…]

In 1947, the Soviet Union established its first smallpox weapons factory just outside the ancient cathedral town of Zagorsk, forty minutes’ drive northwest of Moscow. Zagorsk (now Sergiyev Posad) is the site of the

[…]

A few miles away, in another walled compound, Soviet army scientists at the Virological Center of the Ministry of Defense devoutly cultivated smallpox, Q fever, and Venezuelan equine encephalitis in the embryos of chicken eggs.

[…]

Using tiny syringes, laboratory workers injected microscopic amounts of smallpox virus into eggs and sealed each egg with paraffin. The eggs were placed inside thermostatic ovens for several days while the embryo host cells stirred the virus into life. As it monopolized the cells’ normal growth mechanisms, the virus spawned successive replications of itself until the host was engulfed or destroyed. The eggs were then punctured and the liquid inside poured into special vats and mixed with stabilizing materials. The resulting weapon could remain potent in refrigerated conditions for at least a year.

[…]

Under a state-controlled agricultural system it was easy to conceal the purpose of hijacking so many eggs from the marketplace.

[…]

In 1959, a traveler from India infected forty-six Muscovites with smallpox before authorities realized what had happened. The traveler had been vaccinated, but smallpox vaccinations lose their effectiveness over time, and while his weakened immunity was enough to protect him from suffering the symptoms of the disease, he could still pass it on to others. The strain of Variola major in his system was so virulent that an epidemic was only narrowly averted. Partly in response to this incident, the Soviet government sent a special medical team to India to help purge the virus from the subcontinent.

KGB agents went with them.

They returned to Russia with a strain of Indian smallpox excellently suited to weapons production.

[…]

In the 1970s, smallpox was considered so important to our biological arsenal that the Soviet military command issued an order to maintain an annual stockpile of twenty tons. The weapons were stored at army facilities in Zagorsk. Annual quotas of smallpox were required as it decayed over time.

[…]

The smallpox virus is so hardy that it can remain infectious for long periods, even in the soiled linen of those who have been infected. Smallpox victims are infectious from the moment of their first symptoms until the healing of the last scar, two to three weeks later, and they can transmit the disease to others with as little as a cough.

[…]

Humans are the virus’s only natural hosts. There is no way, therefore, for the disease to propagate in nature.

[…]

There are no therapeutic measures currently available to treat smallpox once symptoms develop.

[…]

Smallpox kills between 30 and 50 percent of unvaccinated victims, a low mortality rate, but its morbidity rate ranges from 60 to 90 percent. For many people, contracting smallpox amounts to a life sentence. Some victims are permanently blinded. Others will bear scars as long as they live.

[…]

Schoolchildren in the United States, Russia, and elsewhere around the world are not vaccinated against the disease, and international travelers are no longer required to show proof of smallpox immunity.

Today there are twelve million doses of smallpox vaccine on hand in the United States—of which only seven million are fully reliable, according to the Centers for Disease Control in Atlanta—a portion of the roughly two hundred million doses available in the world. This sounds like a comfortable amount to meet an emergency, until you consider the damage a smallpox attack would do in a densely populated commuter city like New York.

[…]

During World War II the Western allies explored the possibility of weaponizing several viral diseases, including Venezuelan equine encephalitis and smallpox. American, Canadian, and British scientists found to their frustration that viruses were far more difficult to manipulate than bacteria.

[…]

Aerosols were still in the early stages of development in the 1940s, and most of the approaches considered by the Allies for weaponizing smallpox seem strange today. One method involved grinding an Asian strain of smallpox into a fine powder to dust over letters. By the time the war ended, the Allies had largely given up on weaponizing viruses.

[…]

Fewer than five viral particles of smallpox were sufficient to infect 50 percent of the animals exposed to aerosols in our testing labs. To infect the same percentage of humans with anthrax would require ten thousand to twenty thousand spores. For plague, the comparable figure is fifteen hundred cells. The differences in quantity are too minute to be discernible to the naked eye, but they are significant if you are planning attacks on a large scale. Smallpox requires almost no concentration process.

While we had clung to our egg-and-conveyor-belt method of making smallpox, Western pharmaceutical labs were manufacturing vaccines in special reactors from cultures grown in tissue cells obtained from animals or humans. This technique required expertise.

The word virus comes from the Latin term for poison

Sunday, August 30th, 2026

Biohazard by Ken AlibekThe word virus, Ken Alibek explains (in Biohazard), comes from the Latin term for poison:

Viruses are invisible under most microscopes and hundreds of thousands of times smaller than a grain of sand. Their existence was unsuspected until Dmitry Ivanovsky, a Russian microbiologist, discovered them in the late nineteenth century while investigating an outbreak of mosaic disease in tobacco plants. Ivanovsky found that the mysterious agent responsible for this disease was able to pass through filters that otherwise blocked bacteria. Over half a century would pass before the first virus was seen and identified under an electron microscope, but Ivanovsky’s discovery launched a new field of research into infectious diseases.

[…]

The immune system works on many levels at once, like an army with scouts and infantrymen, naval and air power, a sophisticated information network, and a carefully delineated command structure. Some cells are responsible for surveillance, others for coordinating information; some focus on local maneuvers while still others direct more general attacks. Immunologists distinguish between specific and nonspecific immunological reactions. Specific or acquired immune responses depend on memory cells, which store information about previous invaders and thus play a significant role in conferring immunity.

Among the most important agents in the immune system are T cells. They act as scouts, circulating through the bloodstream and moving into lymph nodes, on the lookout for foreign substances. As soon as a virus enters the bloodstream and infects its first cell, it will be recognized by T cells, which immediately activate, replicating themselves and sending out signals, calling for the formation of antibodies and attracting them to the site of infection. Antibodies are like ground troops. They are particularly effective at attacking viruses and bacteria that are still coursing through the system, before they have infiltrated target cells.

Within seconds of infection, defensive proteins and inflammatory agents are released, which activate natural killer cells and lead them to the site of infection. Interferon, one of the most powerful antiviral agents, degrades viral RNA, slows down protein synthesis, and inhibits viral reproduction in infected cells.

By the end of the first week or the beginning of the second, the body will in many cases have developed virus-specific antibodies, which sometimes seek to neutralize the virus by binding to its surface and preventing it from penetrating into new cells. But viruses are adept and mutate quickly. Countless are now capable of inhibiting and neutralizing the body’s natural defenses, rendering their resistance ineffective.

[…]

More than one hundred different viruses have been identified as causes of the common cold.

Americans live shorter lives despite being much richer

Friday, August 28th, 2026

The reasons Americans live shorter lives despite being much richer than their peers are well-understood at this point, Cremieux explains:

The biggest contributor is that obesity is very bad for health, as countries get richer their citizens tend to get fatter, and America is the richest country.

[…]

All Americans regardless of race are, in principle, exposed to a health care system of the same quality understood broadly, although there are gaps in access, but those access gaps don’t fit the order of the longevity gaps—as a close proxy, in 2024, the insurance rates go Asian > White > Black > Hispanic. These race results and the sex ones combine to produce a picture that cannot be explained by a simple health care-centric story. In fact, when it comes to things the health care system can plausibly intervene on, America is usually the highest-performing country—at least cross-sectionally—or it’s very nearly so. When it comes to lifespan and America’s lag despite its riches, look elsewhere than health care.

There were one or two accidents every week

Thursday, August 27th, 2026

Biohazard by Ken AlibekBy 1986, Ken Alibek explains (in Biohazard), they had over 900 people at the bioweapons plant, and more were coming every month:

There were one or two accidents every week.

Once Gennady Lepyoshkin, the chief of our biosafety directorate, reported that a technician had been infected with anthrax in a lab that was supposed to be sterile. He had an abrasion on his neck, one of the most dangerous places in the body through which to contract cutaneous anthrax. When the neck swells, it interferes with breathing.

At first we treated him with streptomycin and penicillin, the most effective antibiotics for use against cutaneous anthrax, but a painful swelling erupted on his chest and spread over his body, making it increasingly difficult for him to breathe. Within three days, death seemed inevitable. A gloomy message was being prepared for Moscow when, in a final attempt to save his life, we gave him an abnormally high dose of anthrax antiserum. The shock dose worked: he began to recover.

The technician’s narrow escape drove home the potency of our new weapon. Our powdered and liquid formulations of anthrax were three times as strong as the weapons that had been manufactured at Sverdlovsk. It would take only five kilograms of the Anthrax 836 developed at the Kazakhstan base to infect half the people living in a square kilometer of territory; the Sverdlovsk weapon needed at least fifteen kilograms to achieve the same impact.

[…]

Our factory could turn out two tons of anthrax a day in a process as reliable and efficient as producing tanks, trucks, cars, or Coca-Cola.

The cultural anthropology students went up one after the other and explained what they were going to find

Wednesday, August 26th, 2026

Robert Lynch started graduate school in 2006:

Like a lot of anthropology departments at the time, Rutgers was split between the biological anthropologists and cultural anthropologists. Although we were all supposedly in the same department and required to take some of the same classes, it was like putting the math and the art departments together — except they hated each other.

[…]

In our second year, all the graduate students had to present their hypotheses at something called the Dissertation Proposal Defence. It was a crucial moment in the process of getting your PhD in anthropology. All of the biological anthropologists presented research questions that they were planning to test.

[…]

I was already used to the massive differences between the two wings of anthropology, and familiar with the jargon employed by the cultural wing (embodied subjectivity, intersectionality, structural violence, hegemonic knowledge production), but I was still taken aback when the cultural anthropology students went up one after the other and explained what they were going to find. Not what they were hoping to understand, or learn, or test, or discover, but what they were going to find.

[…]

There were no questions. No hypotheses. No data to be collected, let alone analysed. There were claims about arguments being “based on the ethnographic evidence”, but no evidence was ever presented. Conclusions were drawn from a series of assertions.

A clogged air filter was not an unusual occurrence, but it had to be replaced immediately

Tuesday, August 25th, 2026

Biohazard by Ken AlibekKen Alibek explains (in Biohazard) the Sverdlovsk anthrax leak of 1979:

The story went public a few months later—in a way. In November 1979, a Russian magazine published by anti-Soviet émigrés in what was then West Germany reported that an explosion in a military facility in the southwest section of Sverdlovsk had released a cloud of deadly bacteria the previous April. It claimed that as many as a thousand people had died. Western news agencies picked up the story, quoting U.S. intelligence officials who claimed that the accident was clear evidence of Soviet violation of the 1972 Biological Weapons Convention.

Moscow denied the reports. On June 12, 1980, a statement published by the official Soviet news agency TASS declared that there had only been a “natural outbreak of anthrax among domestic animals” in the Sverdlovsk region.

“Cases of skin and intestinal forms of anthrax were reported in people, because dressing of animals was sometimes conducted without observing rules established by veterinary inspections,” the statement said, adding that all of the patients had been treated successfully in local hospitals.

This was a lie, of course.

[…]

I learned the truth by talking to people who had been at the plant when the accident happened, and to army officers who had been in charge of the cleanup.

[…]

As I rose higher in The System, I applied some of the lessons of Sverdlovsk to the plants under my control.

[…]

On the last Friday of March 1979, a technician in the anthrax drying plant at Compound 19, the biological arms production facility in Sverdlovsk, scribbled a quick note for his supervisor before going home. “Filter clogged so I’ve removed it. Replacement necessary,” the note said.

[…]

The fermented anthrax cultures had to be separated from their liquid base and dried before they could be ground into a fine powder for use in an aerosol form, and there were always spores floating in the air. Workers were given regular vaccinations, but the large filters clamped over the exhaust pipes were all that stood between the anthrax dust and the outside world.

After each shift, the big drying machines were shut down briefly for maintenance checks. A clogged air filter was not an unusual occurrence, but it had to be replaced immediately.

Lieutenant Colonel Nikolai Chernyshov, supervisor of the afternoon shift that day, was in as much of a hurry to get home as his workers. Under the army’s rules, he should have recorded the information about the defective filter in the logbook for the next shift, but perhaps the importance of the technician’s note didn’t register in his mind, or perhaps he was simply overtired.

When the night shift manager came on duty, he scanned the logbook. Finding nothing unusual, he gave the command to start the machines up again. A fine dust containing anthrax spores and chemical additives swept through the exhaust pipes into the night air.

Several hours passed before a worker noticed that the filter was missing. The shift supervisor shut the machines down at once and ordered a new filter installed. Several senior officers were informed, but no one alerted city officials or Ministry of Defense headquarters in Moscow.

In the next few days, all the workers on the night shift of a ceramic-making plant across the street from the facility fell ill. The plant had been directly in the path of the wind that night. Within a week, nearly all of them were dead.

By then hospitals were admitting dozens of patients from other areas of town who had worked in the plant’s vicinity. Curiously, there were few women or children among the victims. Years later, some Western analysts wondered if the Soviets had developed a “gender weapon” capable of attacking only adult males. But women seldom worked night shifts in production plants, and few children would have been playing in the streets late on a Friday night.

[…]

That it happened on a Friday night helps explain why the workers were so anxious to get home and why so many people had passed by that evening, heading for a drink at a nearby bar.

[…]

The Soviet Union later claimed that 96 people were stricken with the disease and 66 died. The scientist who was working in the Sverdlovsk facility at the time told me the death toll was 105, but we will probably never know for sure.

[…]

Sverdlovsk residents were informed that the deaths were caused by a truckload of contaminated meat sold on the black market. Printed fliers advised people to stay away from “unofficial” food vendors. More than one hundred stray dogs were rounded up and killed, on the grounds that they represented a danger to public health after having been seen scavenging near markets where the meat was sold. Meanwhile, military sentries were posted in the immediate neighborhood of the plant to keep intruders away, and KGB officers pretending to be doctors visited the homes of victims’ families with falsified death certificates.

[…]

A Northwestern University physics professor named Donald E. Ellis, who was in Sverdlovsk at the time on an exchange program, reported that he noticed nothing unusual in the city. “I don’t exclude the possibility that something may have occurred,” he told The New York Times years later, “but I think either I or my wife would have sensed some effort to protect us from it. We … were not aware of any restrictions.”

[…]

“We couldn’t understand why people continued to die,” a general who was there told me much later. “We assumed that this was a quick, one-time exposure and that our mopping-up would be completed in a few days, but there were deaths for a month and a half after the release.”

The coverup was responsible for turning what began as a medical emergency into a small epidemic.

The local Communist Party boss, who was apparently told that there had been a leak of hazardous material from the plant, ordered city workers to scrub and trim trees, spray roads, and hose down roofs. This spread the spores further through “secondary aerosols”—spores that had settled after the initial release and were stirred up again by the cleanup blitz. Anthrax dust drifted through the city, and new victims arrived at the hospitals with black ulcerous swellings on their skin.

The cutaneous form of anthrax, contracted when spores enter the body through a cut or abrasion on the surface of the skin, occurs naturally in rural areas around the world, especially those with large herds of domestic cattle, sheep, and goats. It is the most common form of anthrax and is rarely lethal when treated with antibiotics such as penicillin. Russians refer to it as the “Siberian ulcer,” as it manifests itself through the formation of small and localized lesions on the surface of the skin. An outbreak of cutaneous anthrax in the region was credible, but it wouldn’t explain why so many factory workers, who could have had no contact with animals, were suddenly sick, or why so many died.

Anthrax spores can survive for years—even decades—in a dormant state. Animals will become infected while foraging for food. The spores germinate in a matter of hours and multiply in their hosts, returning to spore form when they die or on contact with oxygen. Men and women who work with infected animals—butchers, tanners, farmers, and workers in textile mills—become infected in turn through abrasions, by inhaling spores or drinking contaminated water, or, in rare cases, by eating contaminated meat.

[…]

Inhalational anthrax was first identified in the early nineteenth century when workers in a textile mill were exposed to spores released into the air by the new industrial processes developed to make wool. It is often called wool sorters’ disease.

As soon as an anthrax spore enters the body it germinates and begins to multiply. A few days will pass before the anthrax bacteria produce toxins which, in the simplest terms, bind to the protective membranes of target cells and cripple the ability of white blood cells to fight off disease. It is the toxin, and not the bacterium itself, that ravages the body and is responsible for death. If an anthrax victim is treated with high doses of penicillin injected into the bloodstream at short intervals for a week to ten days before the first toxins are released, chances of survival are almost 100 percent. But antibiotics can do little to fight the anthrax toxin. Combinations of penicillin and streptomycin have been used at this stage, but the prognosis is grim.

The headlong trajectory of pulmonary anthrax can be blocked if penicillin is administered before the first symptoms appear. I was told that thousands of Sverdlovsk residents were given antibiotics and vaccinated immediately after the first cases were reported, but it was too late to save the victims who had already begun to suffer from the fever, shortness of breath, and distinctive dark swellings along their chest and neck that mark the onset of pulmonary anthrax.

[…]

I was told by army personnel involved in the cleanup that the corpses of the victims were bathed in chemical disinfectants and that much of the documentary evidence, including hospital records and pathologists’ reports, was destroyed. To add verisimilitude to the cover story, several black-market vendors in Sverdlovsk were imprisoned on charges of selling contaminated meat.

[…]

The Communist Party chairman of Sverdlovsk at the time of the accident was Boris Yeltsin, the first leader of post-Soviet Russia.

[…]

In 1981, Brezhnev signed a secret decree ordering the relocation of all biological weapons-making equipment and materials from Sverdlovsk to Stepnogorsk, a small biological research facility operated by Biopreparat in the remote deserts of northern Kazakhstan.

[…]

For the good of our biological warfare program, Chernyshov’s mistake had to be kept quiet. A thorough investigation of what had happened in Compound 19 would raise too many awkward questions even inside our own government about our activities. This was further proof that secrecy was valued above all else in our system—even if it endangered our own safety. In the West, an accident of such magnitude would have been investigated ad nauseam and its lessons distributed, however quietly, to those working in similar areas. Our coverup virtually guaranteed further disasters.

A few months later I ran into another veteran of Sverdlovsk, Lieutenant Colonel Boris Kozhevnikov. In the year following the accident, he told me, a work crew was ordered to take a boxload of 250-liter containers filled with dried anthrax to storage bunkers inside Compound 19. Kozhevnikov had been assigned to escort the workers as they rolled the containers on carts toward the bunker a few hundred feet away. One cart hit a bump, and a container fell open. I was aghast.

“What did you do?” I asked him.

“I just closed it.” He shrugged.

Hastily, he added that he had ordered disinfectant poured everywhere. No one had fallen sick. And, of course, his superiors were not informed.
