Part ~
Understanding the Spread of
HIV Infection
In Part I, we discuss key aspects of the scientific knowledge re-
quired to understand the spread of the human immunodeficiency
virus (HIV) and the epidemic of acquired immune deficiency syn-
drome (AIDS). Chapter 1 reviews estimates of the current size of
the epidemic and evaluates the statistical data systems that have
been established to monitor the spread of HIV in the United States.
Chapters 2 and 3 discuss the two major classes of behavior that have
spread HIV infection and thereby sustained the epidemic: sexual
behavior and intravenous (IV) drug use.
