The book avoids medical and academic jargon, opting for a more conversational, at times exasperated tone as he recalls the stories behind the headlines. Through the many layers of news gathering and joining the dots, the author explores the social, psychological, and cultural forces, along with the political and medical structures, that dictate how pandemics move through populations. While Part One is a more informal reflection on pandemics, Part Two looks at the tangled roots of such diseases, and how they change society. Part Three goes deeper into the ways they spread globally, including in India, and the role of understanding crowd psychology in controlling them. McNeil also turns his attention inward, with an insider account of “Media’s Forced Errors”, and the sometimes insidious synergy between media outlets, politicians and health agencies and the issue of “sources deceiving reporters”, such as when he believes a group of scientists misled him early in the Covid-19 pandemic.
