Pathology and Epidemiology of HIV

The first cases of AIDS were reported to the Centers for Disease Control and Prevention (CDC) in 1981.

Since that time, HIV/AIDS has emerged as one of the single most significant health threats of our time, claiming the lives of:

  • Over 636,048 people in the United States (as of the end of 2010)
