It was the summer of 1983 and my first day on the job at KPIX -- San Francisco's CBS television affiliate. My assignment: cover a news conference at the Irwin Memorial Blood Bank. It was about the new and mysterious disease, AIDS, and the blood supply. Sitting in the car to return to the station, my head was reeling. I had heard about AIDS in my previous job on the east coast, but nothing more than that. Clearly this had all the earmarks of a tremendously important story. It was a fearful time. People were dying. The nation’s blood supply was somehow at risk. There was an international race to find the cause and, hopefully, some way to treat this terrible disease and save countless lives.
