Doctors in New York, Los Angeles, and San Francisco were mystified as they watched their patients die rapidly of infections they shouldn’t have contracted at all. A medical response would take time they didn’t have—time to identify the virus, to develop a drug, and to push the drug through the FDA’s clinical trial process, which took at least four years.
