Spillover: Animal Infections and the Next Human Pandemic by David Quammen is a fascinating look into the world of infectious diseases, specifically those that travel from animals to humans, otherwise known as zoonosis or spillover. Humankind is all too familiar with zoonoses in the form of influenza, Ebola, SARS and AIDS. In order to get a sense of the scope of interspecies diseases, keep in mind that about 60% of all infectious disease cross between animals and humans. According to Quammen’s research, zoonosis has killed 30 million people since 1981. To investigate spillover viruses, he travels all over the world with virus hunters. He describes multiple mysterious outbreaks of disease, coming from a wide range of animals such as bats, gorillas and pigs. Quammen believes the next major pandemic will come from a nonhuman animal virus that will infect and spread into the human population.
David Quammen is a terrific science writer and he knows how to tell a good story. He is excited about his subject and takes a warm, personal approach with his readers. He makes this very complicated and frightening subject accessible and easy to understand. Spillover is thoroughly researched, includes an extensive bibliography and is chock-full of fascinating, engaging material. Although Quammen takes issue with Richard Preston’s Hot Zone, readers who enjoyed Hot Zone will love Spillover.
