AIDS:
This
refers to persons diagnosed with AIDS,
based on the CDC definition in
adults and adolescents and
children.
-
HIV/AIDS: This refers to
cases of HIV infection, regardless
of whether they have progressed to AIDS
from the 39 areas (34 states and 5 U.S.
dependent areas) that have had
confidential name-based HIV infection
reporting long enough to monitor trends.
According to the number of AIDS cases, these 34 states represent approximately
66% of the epidemic in the 50 states and
the District of Columbia.
-
Dependent Areas: American Samoa, Guam, the Northern
Mariana Islands, Puerto Rico, and the
U.S. Virgin Islands.
- 34 States and 5 Dependent
Areas with Confidential Name-Based HIV
Infection Reporting: Alabama,

about HIV infection reporting.
- Transmission Category:
The
classification of a case that indicates
the risk factor most likely to have been
responsible for transmission. Cases are
counted only once in a hierarchy of
transmission categories. Persons with
more than 1 reported risk factor for HIV
infection are classified in the
transmission category listed first in
the hierarchy. The exception is men who
report sexual contact with other men and
injection drug use; this group makes up
a separate transmission category.
- HIV Incidence: The number
of new HIV infections in a specific
population during a specific period of
time.
- HIV Prevalence:
The number of people living with
HIV/AIDS in a given year.

AIDS data are tabulated, read the "Technical
Notes" from the

HIV Prevalence Estimate
Prevalence is the number of people living with HIV infection
at the end of a given year.
At the end of 2006, an estimated 1,106,400 persons (95% confidence interval 1,056,400-1,156,400) in the United States were living with HIV infection, with 21% undiagnosed.1

Go to top
HIV Incidence Estimate
Incidence is the number
of new HIV infections that occur during a
given year.
In 2008, CDC estimated that approximately
56,300 people were newly infected with HIV
in 20061 (the most recent year that data are
available). Over half (53%) of these new
infections occurred in gay and bisexual men.
Black/African American men and women were also
strongly affected and were estimated to have
an incidence rate than was 7 times as high
as the incidence rate among whites.

AIDS Cases
In 2007, the estimated number
of persons diagnosed with AIDS in the United States
and dependent areas was 37,041.
Of these, 35,962 were diagnosed in the 50
states and the District of Columbia and 812
were diagnosed in the dependent areas. In the 50
states and the District of Columbia, adult and
adolescent AIDS cases totaled 35,934
with 26,355 cases in males
and 9,579 cases in
females, and 28 cases estimated in children under age
13 years.
The cumulative estimated number
of diagnoses of AIDS through 2007 in the
United States and dependent areas was
1,051,875.
Of these, 1,018,428 were diagnosed in the 50
states and the District of Columbia and 32,051 were
diagnosed in the dependent areas.
In the 50 states and the District of Columbia, adult and adolescent AIDS cases totaled
1,009,220 with 810,676 cases in males and
198,544 cases in females, and
9,209 cases estimated in children under
age 13 years.
These numbers do not
represent reported case counts. Rather,
these numbers are point estimates, which
result from adjustments of
reported case counts. The reported case
counts have been adjusted for reporting
delays and for redistribution of cases in
persons initially
reported without an identified risk factor,
but not for incomplete reporting.
Totals include
persons of unknown race or multiple races, persons of unknown sex,
and persons of unknown state of residence. Because
totals were calculated independently of the
values for the subpopulations, subpopulation
values may not equal the totals.
