I set my expectations a bit high for this book, for some reason. The jacket text leads off with a flu epidemic example, and so I thought that there would be a decent amount of text devoted to pandemics (e.g plague, influenza, etc.). Instead, a fleeting reference to the flu gave way to a syphilis outbreak in Baltimore. Not quite as interesting, but mis-set expectations will do that to you. It’s one of the examples from the last rule, however, that made me think the most and therefore kept me from being completely negative in my assessment of the book.
