Dr. Stefan Wiktor is a public-health physician with more than twenty-five years’ experience in epidemiologic research and in the implementation of public-health programs for the control of infectious diseases. Dr. Wiktor started his public-health career at the U.S. National Cancer Institute where he conducted research on the epidemiology of human retroviruses. After joining the U.S. Centers for Disease Control and Prevention, he conducted research studies of HIV-1 and HIV-2 in Ivory Coast, West Africa and led the implementation of a large-scale HIV/AIDS prevention and treatment program in Tanzania. Dr. Wiktor’s research in Africa showed that anti-retroviral medications were effective in preventing mother-to-child HIV transmission. He was also was responsible for showing that antibiotics reduced bacterial infections in HIV-infected adults, thereby reducing the morbidity and mortality of the disease. This research led to the WHO recommendation for antibiotic prophylaxis to prevent deaths in HIV-infected adults.
