I enjoyed the book overall, though the details were tedious at times, and reading it is making me strongly consider a career in pathology. This last section was interesting because the author himself traveled to places such as the cave and the monkey house to trace the origin of the viruses himself. It was a little spooky to know that such a harmful disease was bred where he was standing though. The metaphorical way that he referred to the cave in comparison to a human mouth was interesting and created a very real and very disturbing visual in my head. This whole book has made me a little paranoid of germs and the idea of such deadly viruses being spread so quickly and the end of the novel did not give me any closure to the fact that the virus will not be spread that vastly again.
