This was a solid pop science book on how diseases spread, and what we’re doing (or not doing!) to stop them. The book is structured according to human behaviors vis-a-vis diseases, and also uses cholera as a particular case of a disease with which to weave together the general complexity of epidemiology. I found the overall book a bit disjointed, though many individual parts were quite enjoyable. That said, overall I would’ve liked a bit more depth, especially in the sections concerned with policy.
