Submission + - AIDS Virus Now Estimated to be 100 Years Old
ChazeFroy writes: A new study estimates that the AIDS virus, HIV, started to circulate in the human population between 1884 and 1924, with a more focused estimate at 1908. This is much earlier than the previously-held estimate of 1930. "The new result is 'not a monumental shift, but it means the virus was circulating under our radar even longer than we knew,' says Michael Worobey of the University of Arizona, an author of the new work." The article also speculates that HIV first began to spread in Kinshasa, Congo.
