During the last 5 years, major advances have been made in our understanding of the pathogenesis of human immunodeficiency virus (HIV) disease and in the development of new potent antiviral agents. With regard to HIV pathogenesis, several recent observations have not only changed our perspectives of HIV disease, but have been critical for the design of therapeutic strategies.
