(CNN) -- We've come a long way since my early days as the associate medical director of the AIDS clinic at San Francisco General Hospital in the 1980s and 1990s. By 1990, I had seen over 500 patients die from a disease that we just couldn't treat. As an infectious disease doctor, I was overcome not only by the tragic loss of life, but also by the inability to find the "magic bullet" to help prevent these deaths. Like many of my colleagues, I devoted my time to caring for my patients and to research. I am proud to say that many of the successful antiretroviral treatments (ART) that were developed emerged from San Francisco General.
