Imagining the Post-Antibiotics Future [View all]

After 85 years, antibiotics are growing impotent. So what will medicine, agriculture and everyday life look like if we lose these drugs entirely?

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.

In 2009, three New York physicians cared for a sixty-seven-year-old man who had major surgery and then picked up a hospital infection that was “pan-resistant” — that is, responsive to no antibiotics at all. He died fourteen days later. When his doctors related his case in a medical journal months afterward, they still sounded stunned. “It is a rarity for a physician in the developed world to have a patient die of an overwhelming infection for which there are no therapeutic options,” they said, calling the man’s death “the first instance in our clinical experience in which we had no effective treatment to offer.”

Many treatments require suppressing the immune system, to help destroy cancer or to keep a transplanted organ viable. That suppression makes people unusually vulnerable to infection. Antibiotics reduce the threat; without them, chemotherapy or radiation treatment would be as dangerous as the cancers they seek to cure. Dr. Michael Bell, who leads an infection-prevention division at the CDC, told me: “We deal with that risk now by loading people up with broad-spectrum antibiotics, sometimes for weeks at a stretch. But if you can’t do that, the decision to treat somebody takes on a different ethical tone. Similarly with transplantation. And severe burns are hugely susceptible to infection. Burn units would have a very, very difficult task keeping people alive.”
