What makes you stronger might also kill you. A survey shows that antibiotic use is rampant worldwide, giving rise to drug-resistant bacteria, especially in developing countries. In India, for example, E. coli is nearly untreatable, and globally the use of last-resort drugs has risen 40 percent in a decade. All of this points to a deadly road ahead. Experts suggest that better education about when to use antibiotics, higher rates of vaccination and even simple handwashing can decrease our usage and stop mutating bacteria in their tracks.
