For most of human history, we have sought to treat and cure diseases. But only in recent decades did it become possible to ensure that a particular disease never threatens humanity again. Julie Garon and Walter A. Orenstein detail how the story of smallpox – the first and only disease to be permanently eliminated – shows how disease eradication can happen, and why it is so difficult to achieve.
