Wendy Orent, author of Plague and co-author of Bio Warrior with Soviet plague expert Igor Domaradsky, explains the biology, history, and weaponization of plague, the recent fatal lab infection in Siberia, and why plague remains a uniquely dangerous pathogen that cannot be engineered into something worse than it already is.
Wendy Orent’s path to plague expertise began with the Soviet bioweapons program
She was writing about biological weapons when she obtained a heavily redacted copy of Troublemaker by Domaradsky, which referenced Viktor Zhdanov — the man who proposed smallpox eradication while simultaneously directing the Soviet bioweapons program
Domaradsky confirmed Zhdanov had developed smallpox as a weapon after eradication would leave humanity defenseless
Orent corresponded with Domaradsky, became friends, and helped publish his book in English (Bio Warrior)
Domaradsky, a bacteriologist with two PhDs, was the world’s leading plague expert and sent Orent his plague research, hooking her on the disease
The Soviet bioweapons program (Biopreparat) and its structure
Biopreparat was the civilian branch of the Soviet offensive biological weapons program, run by Domaradsky; a parallel military program operated four closed labs no Western scientist ever entered
Domaradsky started at anti-plague institutes (legitimate public health work) but was pulled into Biopreparat because of his brilliance — the program offered elite scientists a far better life
His nemesis, Urovkov, was a Lysenkoist (ideologically driven pseudoscientist); Domaradsky was a committed Darwinian, creating a deep scientific and ideological rift
Domaradsky discovered virulence factors in plague existed on plasmids (small DNA rings) but couldn’t publish due to secrecy; Robert Brubaker in the US independently discovered plasmids three years later
The anti-plague institutes supplied strains to Biopreparat; the military labs remain a black box — possibly still active
Plague biology: Yersinia pestis is the deadliest bacterium, with unique transmission dynamics
Yersinia pestis is a bacterium, not a virus; among bacteria it is the most virulent and, in its marmot-adapted strains, the most transmissible
Three clinical forms: bubonic (60% untreated mortality), septicemic (100% untreated mortality), pneumonic (100% untreated mortality; death in 2–3 days)
Humans are dead-end hosts; the natural reservoirs are rodents — especially tarbagan marmots in Central Asia/Siberia, prairie dogs and black-footed ferrets in the US
Marmot strains are exceptionally transmissible; some Russian scientists believe they have neurotropism (head straight to lungs), enabling respiratory spread
Pneumonic plague suppresses the immune system; victims feel fine until sudden catastrophic collapse — coughing blood, death within hours
In the US, no person-to-person pneumonic transmission since 1924; in Russia, Mongolia, and China, it happens regularly
Plague cannot be made more virulent (already 100% lethal in septicemic/pneumonic forms); transmissibility genetics are a “black box” — no one knows how to engineer increased spread
Antibiotic resistance can be added via plasmids, but the altered strain is crippled; without constant antibiotic pressure, wild-type outcompetes it and resistance disappears
Historical plague outbreaks reveal the power of pneumonic transmission
Earliest recorded outbreak may be biblical (1 Samuel 5–6): Philistines struck with “emerods in their secret parts” (buboes in groin) alongside a rat/mouse infestation
Black Death (1347–1353) descended from Y. pestis medievalis strains; spread via Mongol armies’ Yam (pony express) system — infected riders traveled days before symptoms appeared
The siege of Caffa (1346): only one contemporary source (Gabriel de Mussis) claims Mongols catapulted plague corpses; a second source (Guy de Chauliac) describes the same siege but says survivors converted to Christianity — no catapults mentioned
Black Death’s speed came from massive pneumonic element plus human flea (Pulex irritans) transmission — person-to-person, not just rat-flea
Physician Guy de Chauliac observed: blood-spitting (pneumonic) arrived first in a new area, followed by buboes; “from the buboes one could sometimes recover, from the blood-spitting never”
Manchurian outbreaks (1910–11, 1920–21, 1921): 60,000, 16,000, and 10,000 deaths respectively — all marmot plague, highly pneumonic
Wu Lien-teh stopped the 1910–11 outbreak with strict quarantine, open-air isolation (plague transmits poorly outdoors), and masking — “no disease is more susceptible to quarantine than plague”
The recent Siberian case: a young woman at an anti-plague institute died; Russian response confirms plague
A lab technician at an anti-plague institute in Siberia died within days; initial claim she broke a test tube contradicted by her mother (also a scientist) who said she was meticulous and would have sought prophylaxis immediately
Most parsimonious explanation: accidental aerosolization during routine work; she inhaled a lethal dose, didn’t realize she was infected until too late
Russian response — FSB lockdown, mass quarantine, antibiotic prophylaxis, then denial (“no plague in Russia”) — is classic Soviet/Russian pattern: plague is officially nonexistent, so outbreaks are denied even while extreme containment measures are taken
Orent expects no further cases because quarantine and treatment were implemented rapidly; anti-plague institutes do legitimate strain-typing work, not weapons research
Lab leaks are common but rarely explained; plague lab leaks are rare
Orent documented numerous lab leaks (smallpox, SARS, etc.) — most are swept under the rug with no definitive explanation
1978 UK: Janet Parker, a photographer above a smallpox lab, infected via air duct; lab director Henry Bedson committed suicide
1966 UK: photographer infected with variola minor (mild smallpox) from same lab; infected 72 people before bartender noticed pustules
2009 Chicago: Malcolm Casadaban, a plague researcher with undiagnosed hemochromatosis (iron overload), died from an attenuated vaccine strain that could not acquire iron — his body supplied it
Biosafety levels: US work on plague sometimes done at BSL-2 (Orent witnessed this at CDC Fort Collins); Russian anti-plague institutes likely similar
Plague as a biological weapon: effective but with constraints
Plague is a strategic weapon (ICBM delivery), not tactical — vaccines don’t work well, own troops would be at risk
Advantages: extreme virulence, person-to-person spread (marmot strains), self-sustaining epidemic (“spread from man to man will go on by itself and no further effort on the part of the military is necessary” — Domaradsky)
Limitations: treatable with antibiotics if caught early; quarantine works; no effective vaccine exists anywhere
Chimeric “designer” plague (e.g., euphoria-inducing, diagnostic evasion) is science fiction — every genetic modification cripples the organism; wild-type always wins
Soviet program wanted marmot strains specifically for their transmissibility; Urovkov said “don’t give me any strains but marmot strains”
Other pathogens compared: smallpox, anthrax, polio, Ebola, Marburg, rabies
Smallpox: good weapon but effective vaccine exists; US has stockpiles for entire population
Anthrax: non-contagious, affects mainly older/compromised people, nearly impossible to clean up
Polio: “most devious virus” — silent spread from asymptomatic carriers, causes paralysis, post-polio syndrome; Orent hates it more than plague
Cutter incident (1955): 200,000 children received incompletely inactivated Salk vaccine; 40,000 got polio, 200 paralyzed, 10 died — tragedy but Salk vaccine now safest known, eliminated polio from India
SV40 (simian virus 40): contaminated polio vaccines 1955–63 (grown on monkey kidneys); harmless in humans despite causing tumors in hamsters; eliminated from stocks decades ago
HIV origin theories (Edward Hooper: contaminated polio vaccine in Congo) debunked by evolutionary biologist Bill Hamilton — HIV entered humans decades earlier
Ebola/Marburg: spread by care rituals (washing dead); no cost to virulence because next host is immediately exposed; supportive care allows survival
Rabies: 100% fatal once symptoms start; “demonic” — hijacks CNS to induce aggression/biting for transmission; post-exposure prophylaxis works if given before symptoms
Vaccines, public trust, and the current landscape
Vaccines are “the greatest triumph in human health”; polio nearly eradicated, smallpox gone
Cutter incident was a one-time manufacturing failure, not an indictment of vaccines
Anti-vaccine sentiment (e.g., RFK Jr., Aaron Siri) is ideological, not scientific; eliminating polio vaccination would bring back iron lungs and paralysis
Pharmaceutical companies have committed crimes (opioids), but that doesn’t invalidate all their products — cancer patients still take chemo/immunotherapy
Biological Weapons Convention has no effective inspection regime; US program shut down by Nixon in 1969; Orent believes no US offensive program existed until possibly recent administration
Soviet/Russian denialism (“plague is illegal, we don’t have it”) persists; military labs remain opaque
Practical implications: plague is containable but requires knowledge and speed
Quarantine, antibiotics, and isolation work — Manchurian villages that self-cordoned survived
Modern outbreaks in US are rare, zoonotic (prairie dogs, cats), not person-to-person
Fear of plague exceeds its actual threat in developed settings with antibiotics and public health infrastructure
The real danger is ignorance: policymakers and public don’t understand plague’s mechanics, leading to either panic or complacency
Orent’s books (Plague, Bio Warrior) remain in print for those who want the science
