For years scientists thought that infectious diseases had been licked. Antibiotics, the drugs used to treat bacterial infections, were the magic cure-all - or so they thought. Scientists never expected the bacteria to fight back. Now the superbugs here - and they're virtually untreatable. They can cause ear infections that won't go away, skin infections that send professional footballers to hospital, and food poisoning that kills. This book explains how superbugs came to be, how scientists are fighting them, and how readers can protect themselves.
