At the end of 2003,* an estimated 1,039,000 to 1,185,000
persons in the United States were living with HIV/AIDS [1].
In 2006, 35,314 new cases of HIV/AIDS in adults, adolescents,
and children were diagnosed in the 33 states with long-term,
confidential name-based HIV reporting [2].
CDC has developed a new and innovative
system designed to estimate the number of
new HIV infections (or incidence) for the
United States in a given year.
Using this new technology, CDC estimates
that 56,300 new HIV infections occurred in
the United States in 2006. [3]
By Sex
In 2006, almost three quarters of HIV/AIDS diagnoses among
adolescents and adults were for males.

By Transmission Category
In 2006, the largest estimated proportion of HIV/AIDS
diagnoses among adults and adolescents were for men who
have sex with men (MSM), followed by persons infected
through high-risk heterosexual contact.

Although blacks, or African Americans,
made up only 13% of the population in the
33 states, they accounted for almost half
of the estimated number of HIV/AIDS
diagnoses made during 2006.

Trends in AIDS Diagnoses and Deaths
During the mid-to-late 1990s, advances in HIV treatments slowed the progression of
HIV infection to AIDS and led to dramatic decreases in deaths among persons with AIDS
living in the 50 states and the District of Columbia. In general, the trend in the estimated
numbers of AIDS cases and deaths remained stable from 2002 through 2005. Estimates
for 2006 suggest that the number of AIDS cases remained stable and that the number of
deaths decreased; however, it is too early to determine whether this trend will hold. Better
treatments have also led to an increase in the number of persons who are living with AIDS.
