Human immunodeficiency virus 1 (HIV-1) is currently the most clinically imporant of the retroviruses. At the end of 1998, an estimated 33.4 million people worldwide were infected with HIV, predominantly with HIV-1 (UNAIDS report). Another virus, HIV-2, is responsible for some cases of AIDS. HIV-2 infection tends to be milder and much less common, comprising less than 1% of HIV cases in most areas of the world.

This page concentrates on certain aspects of HIV-1 infection and disease, but many portions of it are more generally applicable. Comments are welcomed.
