Yesterday morning, I published a story about the silent spread of resistance against the antibiotic of last resort, colistin?a major step toward the emergence of a superbug resistant to all antibiotics. While reporting this story, I interviewed Alex Kallen, an epidemiologist at the CDC, and I asked if anyone had found such a superbug yet. ?Funny you should ask,? he said.
Funny?by which we all mean scary?because yesterday afternoon, the CDC also released a report about a Nevada woman who died after an infection resistant to 26 antibiotics, which is to say all available antibiotics in the U.S. The woman, who was in her 70s, had been previously hospitalized in India after fracturing her leg, which led to an infection of the bone.
