Invisible microbes cause sickness by invading our bodies and multiplying. But doctors didn't always know that sickness was caused by germs. Most people thought diseases came from smelly, damp air. But over time, those ideas changed. A Dutch scientist saw bacteria through his microscope. Doctors realized that when they washed their hands, fewer people died. And a doctor in London recognized that disease could spread through contaminated water. Because of these discoveries, people eventually learned that hygiene was the key to stopping disease. Hospitals used clean surgical instruments, and cities developed trash removal and sewage systems. Learn more about the discovery and defeat of bacteria!

It's easy to take a pill when we aren't feeling well. But did you know that the art of making medicines goes back thousands of years? Early remedies weren't always so easy―or effective. Some seemed downright disgusting. Wine infused with a venomous snake was used to cure fatigue and hair loss. Snail slime soothed burns, and a mixture of ear wax and mud treated headaches. Discover more about how medicine was practiced centuries ago and how, eventually, scientists discovered some truly amazing remedies, from the magic bullet that treated syphilis to the insulin used for diabetes.

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. Diseases like the Black Death wiped out whole towns and villages. Tuberculosis consumed young people like a bloodsucking vampire. And 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 doctors discovered how these diseases and others were spread. Being sick isn't quite as sickening as it was in the past!
