Superbugs flourish worldwide. No one is exempt. Every year in the U.S. alone, they infect more than 2 million people, and of these, kill about 35,000--a low estimate. Annually, too, 700,000 die globally, fast competing with cancer as the world's No. 1 deadliest disease. Many of our common habits have unwittingly fast-tracked their virulence. Seventy per cent of our antibiotics are now largely ineffective, and few new ones are on the way.
