# Biological War: A Scenario
**Biological War: A Scenario** is a 2026 work of narrative nonfiction by the American investigative journalist [Annie Jacobsen](https://www.edgepedia.org/annie-jacobsen) that combines reported history of biological weapons with a hypothetical hour-by-hour account of a global catastrophe triggered by the accidental release of an engineered pathogen from a Russian laboratory. Published by Dutton on July 28, 2026, it follows her bestseller *[Nuclear War: A Scenario](https://www.edgepedia.org/nuclear-war-a-scenario)* (2024) and applies the same ticking-clock structure to biological warfare, a subject the publisher describes as one that had long orbited her reporting.[1](https://www.penguinrandomhouse.com/books/783250/biological-war-by-annie-jacobsen/9798217046034/) The book became an instant New York Times bestseller and a New York Times Editors' Choice.[2](https://books.google.com/books/about/Biological_War.html?id=p-WSEQAAQBAJ)

## The scenario
The book's narrative begins with a lab accident, what scientists call a lab escape or lab leak, at a maximum-security facility in Siberia. In Jacobsen's telling, a scientist who has tried to incinerate the virus he is developing causes an explosion, is infected, and, knowing he will die, goes to confession, infecting others.[4](https://www.kqed.org/forum/2010101914821/annie-jacobsens-doomsday-biological-war-scenario) What escapes is imagined rather than real: a chimeric pathogen based on plague but combining material from other pathogens, engineered for high airborne transmissibility and pneumonic infection, with a basic reproduction number of 11 and an untreated fatality rate near 100 percent.[3](https://jameswphillips.substack.com/p/review-of-annie-jacobsens-biological)
**Spread through travel.** The opening "patient zero" set piece follows unknowingly infected travelers spreading the airborne virus from airport to airport and cruise ship to cruise ship.[7](https://www.kirkusreviews.com/book-reviews/annie-jacobsen/biological-war/) Jacobsen draws the mechanism from the 14th-century bubonic plague, which killed between one-third and one-half of Europe and traveled at the speed humans traveled, about one mile a day by caravan or ship; today, she notes, a person can cross half the planet in half a day, turning an infected airline passenger into a super-spreader event that seeds generation after generation of infection worldwide.[4](https://www.kqed.org/forum/2010101914821/annie-jacobsens-doomsday-biological-war-scenario)
**Government response.** In the scenario, the United States detects the Siberian explosion in its first minutes through the satellite systems that watch for nuclear launches, but, unlike with a missile, there is no way to determine precisely whether a pathogen was released or whether anyone is dying. State Department officials press Moscow for answers and Moscow does not provide them. Jacobsen reports from subject-matter experts that this first window is the only time in which an outbreak could be kept from becoming an epidemic and then a pandemic, and that officials even contemplate a nuclear strike on the site, an option rendered useless because infected people have already boarded planes.[4](https://www.kqed.org/forum/2010101914821/annie-jacobsens-doomsday-biological-war-scenario) A Pentagon wargamer she interviewed, Colonel Thomas Erhardt, told her there is no real homeland defense against a catastrophic pathogen; all that can be done, in his words, is "mitigate extermination."[4](https://www.kqed.org/forum/2010101914821/annie-jacobsens-doomsday-biological-war-scenario)
By "Day Six," in the book's structure, civilization has reached its limit. Scarcities of water, food, and medicine produce panic; false conspiracy theories, riots, and an utter collapse of social trust follow, and the imagined end state is mass death, insurrection, anarchy, and a plague-ravaged landscape.[5](https://theweek.com/culture-life/books/biological-war-the-only-cure) • [1](https://www.penguinrandomhouse.com/books/783250/biological-war-by-annie-jacobsen/9798217046034/)
## Historical grounding
The scenario is built on documented history rather than an existing operational agent. Jacobsen describes the Soviet Union's covert Cold War bioweapons effort, among them a "chimera programme" launched nearly 50 years back that aimed at a weapon resembling the pathogen she imagines: plague bacteria combined with a virus that causes encephalitis, designed so that the antibiotics a victim took would set off the second disease instead of clearing it.[8](https://www.supersummary.com/biological-war/authors-note-part-1-summary/) • [3](https://jameswphillips.substack.com/p/review-of-annie-jacobsens-biological) The book also traces the weaponization of scientific progress from recombinant DNA research, which biochemist [Paul Berg](https://www.edgepedia.org/paul-berg) first created in 1971 by joining genetic material from two viruses, to Soviet efforts to engineer agents capable of defeating existing medical countermeasures.[6](https://sobrief.com/books/biological-war?report_issues=true) • [9](https://www.supersummary.com/biological-war/summary/)
**Scale of the risk.** Jacobsen notes that there are 110 known maximum-security labs in 34 countries housing deadly pathogens, and that, given at least one thesis about the origins of COVID-19, there is no reason to assume one will not escape.[7](https://www.kirkusreviews.com/book-reviews/annie-jacobsen/biological-war/) The book links the dual-use problem, in which the same capabilities support cures and countermeasures or can be misused, to weak treaty enforcement, opaque research oversight, underfunded public-health capacity, and social groups left out of routine surveillance.[6](https://sobrief.com/books/biological-war?report_issues=true)
## The Biological Weapons Convention and oversight
The 1972 [Biological Weapons Convention](https://www.edgepedia.org/biological-weapons-convention) prohibits biological weapons but permits pathogen research described as defensive, a loophole the author argues lets offensive work continue under cover of legitimacy, with no real enforcement mechanism.[8](https://www.supersummary.com/biological-war/authors-note-part-1-summary/) According to the Author's Note, a 2025 State Department evaluation identifies Russia and [North Korea](https://www.edgepedia.org/north-korea) as violating the ban at present, while China and Iran are marked over compliance worries that remain unsettled.[8](https://www.supersummary.com/biological-war/authors-note-part-1-summary/) The debate over gain-of-function research grew heated following prominent experiments, among them the 2001 Australian mousepox study, in which a normally mild virus was unintentionally turned lethal against mice that had already been vaccinated, and the H5N1 ferret flu work of 2011-2012 carried out in the Netherlands and the United States, in which H5N1 gained the ability to spread through the air in the experimental model.[8](https://www.supersummary.com/biological-war/authors-note-part-1-summary/)
## Reception and criticism
Critical response was divided. Dwight Garner in The New York Times wrote that the book "moves like a meteor"; George F. Will in The Washington Post called it the only recent book more disturbing than Jacobsen's previous one and a "summons to seriousness"; [The New Yorker](https://www.edgepedia.org/the-new-yorker) praised it as "a scrupulously realistic book about the inconceivable."[5](https://theweek.com/culture-life/books/biological-war-the-only-cure) • [10](https://www.washingtonpost.com/opinions/2026/07/29/annie-jacobsen-biological-war-plausibly-describes-catastrophe/) • [1](https://www.penguinrandomhouse.com/books/783250/biological-war-by-annie-jacobsen/9798217046034/) [The Spectator](https://www.edgepedia.org/the-spectator)'s reviewer, a participant in a 2020 [Downing Street](https://www.edgepedia.org/downing-street) meeting on pandemic biosecurity, wrote that the book was the briefing his government should have received.[1](https://www.penguinrandomhouse.com/books/783250/biological-war-by-annie-jacobsen/9798217046034/)
**Criticism of the assumptions.** [The Bulletin](https://www.edgepedia.org/the-bulletin) of the Atomic Scientists published a skeptical review arguing that the book's hypothetical set-up is skewed and at times factually inaccurate, and that its scenario assumes extreme transmissibility, near-total lethality, treatment resistance, and infection-induced euphoria would all remain stable as the pathogen spread. The same review observed that, despite the title, *Biological War* is principally a scenario of accidental release, not biological warfare, and that the concept of intent is central to the Biological Weapons Convention.[11](https://thebulletin.org/2026/10/annie-jacobsens-road-from-siberia-to-armageddon-is-paved-with-bad-assumptions/) Reader reviews have also been mixed, with some finding the book thin on science and over-reliant on fictional license, and others valuing its account of catastrophic risks at high-containment laboratories.[6](https://sobrief.com/books/biological-war?report_issues=true)
