A new study publicized in the journal Nature changes the scale of HIV infection. Previously, it was thought that HIV had been present in human populations by around 1930; the new study suggests that HIV was present in humans as far back as 1884.
Central to this new information is the fact that HIV is extremely quick to mutate, and knowing that the virus has infected humans for a longer period of time helps to explain a greater variation in strains of the virus. The study does not fundamentally change our understanding of HIV, and it is important to note that more research must be done to best use this information to eradicate the pandemic.
