Wise, witty, authoritative, this book chronicles the influence of our tiny enemies on human history. Microbiologist Jason Tetro has studied germs for 25 years. He relates how pandemics such as the plague, HIV and "swine flu" came about, how others have been averted and how more may occur if we aren't careful. He explains too that not every germ is a plague waiting to happen, and offers advice on harnessing the power of the good ones to keep us healthy and make our planet a better place.
