Plague!

Being sick is horrible. But it used to be worse. Inside this book, you'll see evidence of the plagues of the past-rotting skin, dissolving lungs, and sinister swelling all over the body. The Black Death wiped out whole towns and villages, Tuberculosis consumed young people like a bloodsucking vampire. Smallpox left its victims scarred for life-if they survived. At the time, no one knew where these killer diseases came from or how to treat them. But eventually an English doctor discovered how cholera was spread, and a Cuban doctor learned that mosquitoes spread yellow fever. Because of doctors like these, being sick isn't quite so sickening anymore. Read all the books in the Sickening History of Medicine series: Plague!
