This was an interesting read and had a lot of unique insights into not only the 2 diseases covered but also the approaches taken in combating them. One can't help but be a bit depressed by the motives and results of some of these endeavours, but conversely be inspired by the ingenuity of some. 

The writing is that of a seasoned non fiction author and can't be readily faulted. On occasion I felt hindsight was helping a bit in the judgement but overall the critiques were justifiable. The short passages at the start of the two major sections linking the diseases with a specific case were great, and whilst they were referred to later on it was without the level of reference to really pull you in. A little more linking to these, or additional case studies would have been good. 

It's a good read, very interesting, but could do a little more to engage the reader who is not a student of the topic
