From fake news to COVID-19, a "smart and engaging" (New York Times) look at why the science of outbreaks is the science of modern life

It’s undeniable that we live in a world shaped by outbreaks. Whether it’s pandemic disease, misinformation, or violence, grasping why exactly some things spread is essential for understanding the world around us. In The Rules of Contagion, Adam Kucharski uncovers the crucial factors driving outbreaks, exploring what it actually means for something to “go viral.” He offers compelling insights into human behavior, ultimately showing us how we can all get better at predicting outbreaks—and how they can be stopped. Revised in light of the COVID-19 pandemic, this is a comprehensive and essential guide to our times.

Editorial Reviews

"In this smart and engaging tour of epidemiology, written before the pandemic, Kucharski makes a convincing case that just as the arc of an epidemic depends on the transmissibility of a virus and a population's susceptibility to infection, so online contagions obey similar rules."—New York Times Book Review

"The Rules of Contagion is a fascinating and richly detailed excursion into a science as old as biblical plagues and as current as today's headlines: the science of contagion, of disease, of ideas, of emotions, of everything. This is a book you'll want to spread to your friends."— Jordan Ellenberg, author of How Not to Be Wrong

"Perfect timing.... Prepares the ground comprehensively for readers to make sense of what is happening today, by distilling the wisdom gathered by studying previous epidemics over more than a century."—Financial Times

"Learned and lucid.... Coronavirus has prompted hot-headed public and media reaction; this book offers comfort in the form of cold, hard facts."—The Prospect

"A fascinating exploration of the mathematics of things that go viral—not least of them viruses.... Kucharski takes his readers down provocative detours, such as the use of public-health models of disease transmission to examine how social networks figure in urban gun violence, with algorithms that take into account such things as 'age gang affiliations, and prior arrests.'... Utterly timely and readable."—Kirkus Reviews

"It is hard to imagine a more timely book ... much of the modern world will make more sense having read it."—The Times (UK)

"This is a hell of a moment for a book like this to come out ... the principles of contagion, which, Kucharski argues, can be applied to everything from folk stories and financial crises to itching and loneliness, are suddenly of pressing interest to all of us."—Sunday Times (UK)

"The Rules of Contagion is popular science at its best. The prose is sparkling and clear. The subject is deeply fascinating and highly relevant. Touching on psychology, medicine, network theory and mathematics, epidemiologist Adam Kucharski has written a brilliant and authoritative guide to the hidden laws of how things spread - from ideas and memes, to violence and deadly viruses. An example of its subject matter, this book is also highly contagious: once you have read it, you will want to make sure others read it too."
—Alex Bellos, author of Alex's Adventures in Numberland

"Rich in stories, The Rules of Contagion is a down-to-earth account of how mathematical approaches can help us better understand and, in turn, better respond to contagion in all its dynamic forms. Tackling issues from pandemics and gun violence, to financial crises and misinformation, Adam Kucharski inspires us all to think like mathematicians. A must read for anybody interested in epidemics and other crises."—Peter Piot, director of the London School of Hygiene & Tropical Medicine

From the Publisher

This popular science audiobook is mostly about infectious diseases like COVID-19 but also covers phenomena like destructive social media content, financial bubbles, and gun violence. Citing the fascinating histories of communicable diseases we’ve faced in the past few centuries, the author, a London medical school professor, explains the many variables that can interact to speed or slow contagion. Joe Jameson, also a Brit, delivers a narration that is appealing to the ear and blends well with the author’s narrative style. This textured audio is full of informative details, math formulas, and scientific constructs yet sounds friendly and digestible. The production is a model of how good storytelling combined with an excellent performance can bring science to the masses when it’s really needed. T.W. © AudioFile 2020, Portland, Maine

A geeky but fascinating exploration of the mathematics of things that go viral—not least of them viruses.

“If we want a better grasp of contagion, we need to account for its dynamic nature,” writes Kucharski, who does mathematical modeling of disease transmission at the London School of Hygiene & Tropical Medicine. He elaborates throughout: Contagion is constantly in motion as it courses through a population, finding its “susceptibles” and slowing down as the number of susceptibles declines. By the author’s capable account, the math works out pretty much the same whether applied to some negative force, such as a COVID-19 category virus or the concomitant financial crumbling that has surrounded it, or some positive force—e.g., a cultural innovation such as a pop song or dance move. Kucharski works his way through some key epidemiological ideas, including one advanced by the scientist who put it together that malaria was spread by mosquitos, earning him the Nobel Prize—although that scientist later protested that his larger achievement was formulating “general laws of epidemics.” These laws embody a mathematical formula that looks rather like an hourglass turned on its side, representing three key groups: the susceptible, the infectious, and the recovered. There are also the dead, of course, but they don’t move, as the dynamic model does. Kucharski takes his readers down provocative detours, such as the use of public-health models of disease transmission to examine how social networks figure in urban gun violence, with algorithms that take into account such things as “age gang affiliations, and prior arrests.” When things go viral, all kinds of interesting mathematical and real-world effects can happen, from stock market bubbles to horrific explosions of disease. Kucharski is there, calculator in hand, to suss it all out, and highly numerate readers will enjoy going along with the ride to guesstimate the R value of a contagion’s spread.

Utterly timely and readable, if not terribly comforting in the midst of the current pandemic.
