Query: Great insight into diseases after WWII.Slows down in middle

As others have stated, real life is a lot more frightening than Hollywood. First chapters are great and read like a novel. Halfway through the book, chapters start giving too many facts per paragraph which tend to make the book boring and slow. Last couple of chapters make up for it with a great conclusion. Provides great insight into how human activity (and arrogance) have contributed to the emergence of diseases after WWII. It's scary how ordinary activities can be dangerous and irresponsible when confronted with diseases that threaten our own existence. YOU MUST READ THIS BOOK if your care about human nature and the impact we, as a society, are having on the world around us, and how that world is fighting back with soldiers called: bacteria, viruses and parasites. After reading this book I'm not so sure who's going to win that war.
