Research Reports: HIV/AIDS
What Is the Scope of HIV/AIDS in the United States?
Currently, an estimated 1 million people in the United States are living with HIV/AIDS. In this country, annual reported AIDS cases peaked in 1993 at approximately 80,000. Between 1993 and 1998, the incidence of new cases declined steadily before leveling off between 1999 and 2001. However, since 2001, the number of new cases has increased slightly each year with approximately 42,500 new AIDS cases reported in 2004.
The number of HIV infections is harder to confirm given that, unlike AIDS reporting, HIV reporting is not mandatory. Currently, only about two-thirds of States report HIV infections; from these data, it is estimated that 40,000 new HIV infections have been occurring annually since the early 1990s, down from the peak of 160,000 new infections per year in the mid-1980s. Nonetheless, the persistence of this rate for more than a decade indicates that much remains to be done to improve the effectiveness of HIV prevention.
