Before that, diseases like pneumonia and tuberculosis were often a death sentence, and even an infected scratch could be fatal. Since then, antibiotics have saved hundreds of millions of lives.

They've become resistant to the very drugs designed to kill them. A study commissioned by the British government estimates that by 2050, 10 million people worldwide could die each year from antibiotic resistant bacteria. That's more than currently die from cancer. To understand the danger posed by superbugs, we start with the story of David Ricci...
