Tracing the Origins of HIV in Humans

Tracing the Origins of HIV in Humans

Host: Mark Nolan Hill, MD

Guest: Michael Worobey, PhD

Previous estimates indicate that the earliest signs of HIV in humans appeared in Africa during the 1930s. Historical data indicates the disease made its way to Haiti, its first stop in the Western Hemisphere, and then eventually on to the United States. But we're learning that the disease may have circulated in Africa for decades before heading west. Does this new information about the origin of HIV offer any clues about the eventual demise of the virus? Dr. Michael Worobey, assistant professor of ecology and evolutionary biology at the University of Arizona, shares details of his research that traces the genesis of HIV/AIDS in humans to the turn of the 20th century.
