With antibiotics losing usefulness so quickly — and thus not making back the estimated $1 billion per drug it costs to create them — the pharmaceutical industry lost enthusiasm for making more. In 2004, there were only five new antibiotics in development, compared to more than 500 chronic-disease drugs for which resistance is not an issue — and which, unlike antibiotics, are taken for years, not days. Since then, resistant bugs have grown more numerous and by sharing DNA with each other, have become even tougher to treat with the few drugs that remain. In 2009, and again this year, researchers in Europe and the United States sounded the alarm over an ominous form of resistance known as CRE, for which only one antibiotic still works.
Health authorities have struggled to convince the public that this is a crisis. In September, Dr. Thomas Frieden, the director of the U.S. Centers for Disease Control and Prevention, issued a blunt warning: “If we’re not careful, we will soon be in a post-antibiotic era. For some patients and some microbes, we are already there.” The chief medical officer of the United Kingdom, Dame Sally Davies — who calls antibiotic resistance as serious a threat as terrorism — recently published a book in which she imagines what might come next. She sketches a world where infection is so dangerous that anyone with even minor symptoms would be locked in confinement until they recover or die. It is a dark vision, meant to disturb. But it may actually underplay what the loss of antibiotics would mean.
