A 39-year-old member asked:

How has human immunodeficiency virus (hiv) evolved since late 1970s?

Probably not: The virus itself probably hasn't evolved much. What has evolved is our ability to treat it. Resistance mutations occur, but this sort of evolution affects individuals and sometimes the people they infect. It has not resulted in global evoluation of the virus.

Blood: Tainted blood transfusions are the easiest way to become infected with hiv. In the developed world, all blood is screened for HIV and blood transfusions are safe. Other high risk activities include sharing needles for intravenous drug use with infected individuals and having unprotected receptive anal intercourse with an HIV infected person.
