There were cameras literally everywhere, in London. So far, he’s managed not to think about them. He remembered Bigend saying they were a symptom of autoimmune disease, the state’s protective mechanisms ‘roiding up into something actively destructive, chronic; watchful eyes, eroding the healthy function of that which they ostensibly protected. –William Gibson (2010)
This summer Ron Fouchier’s lab in the Netherlands conducted an experiment as frightening for its simplicity as for its results. The team produced a human-transmissible version of highly pathogenic influenza A (H5N1) or bird flu.
Rather than by reverse genetics, wherein a complex round robin of mutations are introduced in an effort to produce a human-specific bird flu, an approach which failed most recently at CDC, the Fouchier group let the virus converge on a solution all on its own. HPAI H5N1 was intranasally inoculated into a group of lab ferrets (whose immune response mimics humans’). Only ten infection generations later the virus went “airborne”—transmitted by respiration—while remaining as deadly as its field cousins (with a 75% case fatality rate). A repeat of the experiment reproduced the result.
