If you want confirmation of why this is a good day and age to live in, read this book. It’s a fairly comprehensive take on our contagious diseases, and how they have spread and mutated through the aeons. It’s not until recently that we have had the first true inclination of what actually makes us sick - microbes and viruses. You will learn about the difference between typhus and typhoid fever and why “cow” (vacca) is indicated in the word “vaccination”. Enjoy!
