The sudden emergence of the AIDS pandemic in the 20th century raised questions about AIDS origin(s), including the timing and root causes. Research led to understanding that HIV/AIDS is not one pandemic, but rather a combination of multiple epidemics and failed outbreaks, alongside the well known pandemic. The sources of all HIVs are simian immunodeficiency viruses (SIVs) on the African continent. Finding SIV and the evolution of SIV to HIV will be presented, along with prevailing theories on why AIDS emerged in the 20th century.
Dr. Preston Marx is Professor of Tropical Medicine and Chair of the Division of Microbiology at the Tulane National Primate Research Center of Tulane University. A virologist with over 40 years of experience in research on non-human primate models of AIDS vaccines and the origins of the AIDS epidemics, Dr. Marx’s research contributions include finding Simian Immunodeficiency Viruses (SIV’s) in sooty mangabeys in West Africa, showing this particular mangabey monkey sub-species as the source of HIV-2. Dr. Marx has conducted research projects in Sierra Leone, Gabon, Cameroon and the Republic of Congo. He recently published research in Science magazine showing that the SIV family of viruses is hundreds of thousands of years older than previously believed.
