I love diseases. It's a topic that fascinates me. So when I say I found this book difficult and unsatisfying to get through, you have some idea of my disappointment.
I this the crucial issue is that it is mis-pitched. Clearly Mary Dobson wants to share her passion with a general public, however rather than reading like other engaging pop-sci books (The Ghost Map, Parasite Rex, Level 4-Virus Hunters of the CDC), the disjointed style and 600 page length reads more like an encyclopedia. Like an encyclopedia, there is much repetition with each entry. However, unlike an encyclopedia which should have a level of detail, because this is all crammed into standard book dimensions, a number of things are covered frustratingly fleetingly or not at all. For example very few of the parasitic diseases are covered or even mentioned.
The disjointed feel of the book is not helped by its indecision over what the primary subject is. Is it a history of the diseases, or is it a history of humanity's experiences with disease? Some chapters flip clumsily between the two, leaving the reader feeling like you have started two stories and finished none.
The end of the book, Lifestyle Diseases, is a complete let down. Covering primarily Alzheimers, Heart Disease, and Cancer, this conclusion to the book betrays the title of "Murderous CONTAGION" and is in fact the least interesting section of the book.
Criticisms aside, some parts were genuinely interesting to read and there is a lot of information here, particularly if you have not really looked at these diseases before.
I'm conclusion, though, disappointing and a trudge to read through. Would have been better either with a larger format and more detail as an encyclopedia, or rewritten with some sense of narrative and less detail in parts.
