Tucson, AZ (AHN) - The discovery of a 50-year-old human tissue sample in an African university shows that HIV/AIDS pandemic in humans originated at least three decades earlier than previously thought.

Michael Worobey, an evolutionary biologist at the University of Arizona, Tucson, and lead author of the study suggests that AIDS may have been triggered by rapid urbanization in west-central Africa during the early 20th century and the virus most likely started circulating among humans in sub-Saharan Africa sometime between 1884 and 1924.
